SSD

SSD硬碟和HDD硬碟有何區別？

SSD和HDD的最大區別之一是SSD硬碟沒有移動部件。由於沒有移動部件，SSD硬碟的速度更快，更安靜，抗衝擊力和抗震力也更強。

如何在計算機中安裝SSD硬碟？

請參閱快速入門指南，網址： https://www.lexar.com/cn/support/downloads/

安裝SSD之前是否需要安裝驅動程式？

一般來講，如果SSD支持SATA接口，則Windows 7和10中內置驅動程式。無需安裝任何第三方驅動程式。
如果SSD支持PCIe，則必須在Windows 7中安裝NVMe驅動程式。Windows 10具有PCIe SSD的本地驅動程式。

什麼是「S.M.A.R.T」？如何檢查SSD的S.M.A.R.T？

S.M.A.R.T代表「Self-Monitor and Report Technology」（自我監測和報告技術），內置在硬碟和固態硬碟中以指示硬碟狀態。所有Lexar SSD系列都支持S.M.A.R.T，並且Lexar提供的SSD Dash工具可在Lexar官網上免費下載，以幫助用戶輕鬆獲取S.M.A.R.T值。S.M.A.R.T包含平均P/E週期計數、總通電時間、通電週期計數、總主機寫入/讀取數和其他特定信息。

購買新的SSD時，如何將操作系統和數據保留在原始硬碟中？

建議採用系統克隆方式將操作系統傳輸至SSD。它將保留計算機所需的所有數據、設置和驅動程式。要克隆硬碟，Lexar建議使用EaseUS Todo Backup作為助理，更多詳情請訪問https://www.easeus.com/ 。

什麼是「垃圾回收」？

在SSD中，會在使用過程中產生大量分散數據塊。垃圾回收（所謂的GC）機制將這些數據塊移至特定物理單元，然後重新使用原始單元存儲新數據。垃圾回收是必要的，並可提高SSD的整體性能。Lexar優化高效GC的算法以確保SSD運行順暢。

什麼是「Trim」？Trim和垃圾回收之間的關係是什麼？

TRIM是OS（操作系統）命令集，在Windows 7中開始支持。當用戶刪除文件時，OS發送TRIM以通知SSD此刪除操作，然後SSD將特定存儲單元標記為無效狀態。一旦GC操作，GC就可以更準確高效地擦除存儲單元，無需在閃存中重新分配數據。

什麼是「M.2」？

M.2稱為NGFF（Next Generation Form Factor，下一代外形規範），允許將功能擴展、收縮和高度集成到單個外形規範中。SSD是採用M.2的設備之一，輕薄緊湊，可靈活適應不同的設備。

為何我的性能基準與期望值不同？

測試值因不同基準工具而異。
工具的版本也對測試結果有影響。
平台可能也會影響結果。一般而言，在高端平台上的性能會更好。
如果SSD被使用過，裡面包含數據，則可能會有點慢。

即使在相同的條件下，單個測試的結果也有細微差別。

如何檢查計算機是否兼容可使用M.2 Pcle SSD？

M.2插槽可能僅支持SATA協議。購買M.2 PCIe SSD前，請聯繫服務中心或訪問PC/筆記本電腦/主板製造商網址，獲取詳細規範。

SSD需要進行碎片整理嗎？

SSD具有耗損均衡機制。此機制可確保每單個物理存儲單元都獲得相同的P/E週期。它旨在延長工作壽命。不需要碎片整理。

修改或篡改SSD硬碟會使保修失效嗎？

修改或篡改SSD硬碟會使保修失效。

NVMe M.2 SSD硬碟是否適用於任何M.2插槽？

否，請驗證您的筆記本電腦或台式機是否支持NVMe SSD硬碟。

SD/microSD

什麼是 SD UHS?

UHS 是超高速度（Ultra High Speed）的英文縮寫，指的是 SDHC 記憶卡和 SDXC 記憶卡提高總線接口速度的新技術。
UHS-I最高傳輸速度（理論值）為104MB/s，支持UHS的SDHC/SDXC記憶卡讀寫性能可提升至104MB/s。UHS-I 可使接口速度達到每秒104MB，而支持 UHS 的 SDHC 卡或 SDXC 卡的傳輸性能可提升至每秒104MB。
UHS-II是新一代UHS。 UHS-II將接口速度提高到312MB / s。比UHS-I快3倍。

*資料來源：SD協會

什麼是 U1/U3 速度等級？

有些新的UHS記憶卡會標稱U1速度，這表示該UHS-I具備U1速度等級，代表錄制視頻內容最低寫入速度為10MB/s。值得注意的是，雖然U1速度等級與Class 10的速度相同，但二者測試方式不同，符合其中一種速度等級並不意味著同時也符合另外一種速度等級。U3 標記意味著記憶卡性能需要達每秒30MB才能滿足4K分辨率的錄制和播放。

什麼是 V30/V60/V90視頻速度等級？

它代表視頻錄制與寫入恆定速度的分級。分為三種速度等級，「速度等級」，「UHS速度等級」和「視頻速度等級」。此速度等級通過指定最低寫入性能來提供視頻記錄所需的恆定速度。這包括V6，V10，V30，V60和V90。 V6 Speed Class意味著記憶卡的最低寫入速度需要達到每秒6MB，V10為每秒10MB，30為每秒30MB，依此類推。

V60和V90可應用於高分辨率和高質量的8K視頻錄制，V30可應用於4K分辨率。

SD卡製造商會在其記憶卡(SDHC，SDXC，UHS-I，UHS-II和其他SD記憶卡等)打印上這些速度等級（V60，V90等）。用戶可依照不同速度等級挑選最符合使用需求的記憶卡。

*資料來源：SD協會

什麼是A1 / A2應用性能等級？

它用於智能手機應用程序性能分類。應用程序性能等級1（A1）和等級2（A2）定義隨機讀/寫IOPS的最小平均值。 A1的IOPS規格讀取1500IOPS /寫入500IOPS，最小持續順序性能為10MB / s。 A2的IOPS規格比A1快幾倍。隨機讀取為4000IOPS，隨機寫入為4000IOPS。這意味著A2的寫入性能比A1讀取性能快，並且最小持續順序性能也是10MB / s。

JUMPDRIVE® 隨身碟常見問答

Lexar U盤不支持 4GB 或更大的文件，這是什麼原因？

要傳輸大於 4GB 的文件，必須具有 NTFS 或 exFAT 文件系統。 U盤出廠時的默認的文件系統是FAT32，不能處理大於 4GB（準確地說是比 4GB 小一個字節）的單個文件。

請按照下面的步驟，使用 NTFS 文件系統來格式化U盤：
警告，U盤上的所有數據將會丟失！繼續之前，請備份U盤上的數據。

1.打開”我的電腦”（Vista 和 7 中為”計算機”）。右鍵點擊Lexar U 盤並選擇”格式化”。
2.從文件系統下拉列表中選擇 NTFS 或 exFAT。
3.選擇「快速格式化」作為「格式化」選項，然後單擊「開始」。
注：如果 NTFS 不是可用的選項，請關閉”格式化”窗口並按步驟 4-9 操作。
4.右鍵單擊「我的電腦」（Vista 中為「計算機」），然後選擇「屬性」。
5.選擇「硬件」選項卡，然後單擊「設備管理器」。
6.展開磁盤驅動器，然後右鍵單擊Lexar U 盤。選擇「屬性」。
7.單擊「策略」選項卡，然後選擇「為提高性能而優化」。
8.單擊「確定」。
9.重復步驟 1-3。

請注意，MacOS 10.6.5 支持對 exFAT 格式的驅動器進行完全的讀寫訪問。 MacOS 仍然只能對 NTFS 格式的驅動器進行只讀訪問。有些設備（MP3 播放器、數碼相框等）無法讀取 NTFS 或 exFAT 文件系統。此外，Windows XP 和 Vista 需要更新才能訪問 exFAT。

能否將Lexar U盤，作為可啓動的 USB 設備？

雖然可以從U盤啓動，但這並不是Lexar 支持的功能，U盤原本是作為存儲盤來使用的。

Lexar U盤否具有寫保護功能？

Lexar U盤不具寫保護功能。如果您使用 U 盤是遇到寫保護消息，請檢查以下各項：
1. 確認您被允許對可移動存儲設備進行寫入。操作系統中可能有安全設置禁用對可移動存儲設備的寫入訪問。

2. 確認您是否在使用U盤時啓用了第三方軟件的寫保護。
如果以上都不是，那麼 U 盤可能有故障。請與售後服務部門聯繫獲取進一步的幫助。

USB3.0與USB3.1一樣嗎?

USB3.1是USB協會制訂的規範，USB3.1可以分為USB3.1 Gen1以及USB3.1 Gen2:
USB3.1 Gen1 (SuperSpeed): 最高理論傳輸速度為5 Gb/s(等同於USB3.0)。
USB3.1 Gen2 (SuperSpeed+): 最高理論傳輸速度為10 Gb/s。
實際速度依產品規格為主。

U盤產品在計算機認不到，遇到這樣的狀況應該如何處理?

A請先檢查認不到的那台計算機USB插槽功能是否正常，以及是否掛載對應的隨身碟驅動程式，若排除插槽功能以及驅動程式問題後仍然認不到，請聯繫售後服務。

有些金屬殼U盤產品，使用後摸起來熱熱的，這是正常的嗎?

由於金屬材質的U盤外殼相較於塑料材質的U盤外殼，更容易傳導溫度，所以使用後溫度與塑料材質的U盤相比較高，此屬正常現象，請安心使用。

USB1.0/USB1.1/USB2.0/USB3.0/USB3.1的傳輸速率各是多少?

USB 1.0的最高理論速率為1.5 Mb/s傳輸數據*。
USB 1.1的最高理論速率為12 Mb/s*傳輸數據*。
USB 2.0的最高理論速率為480 Mb/s傳輸數據*。
USB 3.0 及 3.1（Gen 1）的最高理論速率為5 Gb/s傳輸數據*。
USB 3.1（Gen2）的最高理論速率為10 Gb/s傳輸數據*。

*實際速度根據不同產品而有不同

什麼是USB type-C接頭?

USB Type-C，又稱USB-C，是一種通用串行總線（USB）的硬件接口形式，外觀上最大特點在於其上下端完全一致，與Micro-USB相比這意味著用戶不必再區分USB正反面，兩個方向都可以插入。
USB Type-C支持OTG功能，即在沒有主機(例如個人計算機)的情況下，便攜設備之間可直接實現數據傳輸，可支持到USB3.1規格，亦可向下兼容。

什麼是Micro USB接頭?

在許多智能型手機和平板計算機上替代Mini-USB，比Mini-USB插頭高度減半，寬度相差無幾。
Micro-USB標準支持目前USB的OTG功能，即在沒有主機(例如個人計算機)的情況下，便攜設備之間可直接實現數據傳輸，兼容USB1.1和USB 2.0規格。

U盤如何正確使用?

請將U盤 USB接頭插入計算機對應的USB接口，計算機會自動跳出文件夾窗口。
若不使用U盤時請先「安全地移除硬件」並選「退出USB DISK」，之後再將U盤拔除計算機端。

要如何才能保護我U盤的數據呢?

使用完USB裝置時，拔除USB裝置前請正確執行「安全地移除硬件」的動作。
如果是重要數據請養成做備份在其他儲存裝置的習慣，因為任何儲存裝置都有使用壽命無法”永久”的保存數據。
Q: USB 2.0 跟 USB 3.1在儲存數據上會有差異嗎?
A: USB2.0在數據傳輸上理論速度會較USB3.1來的慢，但在儲存數據的功能沒有不同。
且USB3.1標準的U盤或是插槽可以向下兼容USB2.0的接口。

計算機只有USB 2.0 的插孔，能使用USB 3.0的U盤嗎?

USB3.0能夠向下兼容USB2.0規格，故不影響讀寫數據的功能，但將USB3.0 U盤使用在USB2.0插槽上會受到傳輸速度的限制。

要如何查看我的U盤容量呢?

請至「我的計算機」中，在U盤圖標上點右鍵再點選「內容」，即會顯示隨身碟裝置的容量。
亦可透過「計算機管理」中的「磁盤管理」來確認U盤的容量。（不同電腦系統，功能名稱可能不同）

U盤是通過什麼方式來儲存數據?

U盤是透過NAND Flash當作儲存數據的組件，NAND Flash透過充電以及放電(寫入/抹除)的方式來存放數據這類儲存裝置擁有比傳統硬碟重量輕、體積小、省電、不怕震動以及效能更好等優勢。

如何更改U盤的名稱?

在U盤圖標點選右鍵「重新命名」即可更改U盤名稱，或透過格式化的方式在「磁盤區卷標」的字段更改名稱，格式化前請先將數據備份，以免數據因格式化被刪除。

在傳輸數據的過程中不小心拔掉U盤會發生什麼事?

請注意避免在數據傳輸過程中拔掉U盤，這樣的動作會造成檔案在傳輸過程中數據遺失，甚至可能造成U盤的功能異常。
若使用完U盤，請先「安全的移除裝置」再將U盤拔除插槽。

Using the App

Home Screen

Does the app work the same on a tablet as on an iPhone?

The functionality of the app is the same. There may be slight differences in navigation due to the available screen size of the tablet vs. the iPhone format.

Phone navigation – Encrypt (or Decrypt), Rename, Get info, Zip, and Zip and Lock are all located under 「More.」

Tablet navigation—More functions visible

On the Home screen, what does the percentage and the 「free」 refer to under Internal Storage and External Storage?

The home screen displays your available storage on your device (phone/tablet) under Internal Storage, and your available storage on your connected Lexar product under External Storage.

Why can’t I see all the files on my phone/tablet when I tap on 「Internal Storage」 on the Home screen.

Tapping on Internal Storage on the Home screen provides access to only those files stored in the app’s internal storage, and does not provide access to all files on your device.

What does External Storage refer to?

External storage is the storage on your connected Lexar iOS-compatible device.

Why does External Storage say N/A?

External Storage will display N/A until you connect your Lexar iOS-compatible device.

I have added files to my external storage device and the storage available display has not changed. How do I get it to refresh?

Tap on the refresh icon in the upper right corner of the Home screen to immediately refresh your available storage display.

What do the individual icons on the Home screen do?

Tapping on 「Music,」「Photos,」「Videos,」 or 「Documents」 will display only those file types, whether stored in Internal Storage (within the app), or in External Storage (on your Lexar device). Backup will take you to the backup function, and camera will launch the app’s camera.

How do I modify the app’s settings?

To access the Settings screen, tap on the settings icon located in the upper right corner of the Home screen.

Setting Screen

What does turning the support setting to the 「ON」 position do?
Turning on the Support function creates a new email to the Lexar support team from the primary email address linked to your device. It will automatically include your app specifications, making it easy for you to send an email to get answers based on your version of the app.

What is required for TouchID to work with my app?

This function will only work with devices with TouchID. TouchID must be available and enabled on your device.

Do I need to toggle the Auto Backup function to the “ON” position in order to do any backups?

The Auto Backup function in the Settings screen will allow automatic backups of photos, contacts, or both, every time your Lexar iOS-compatible product is connected to your device. You can still perform manual backups at any time, regardless of whether the Auto Backup function is turned on or not.

Which files will Auto Backup back up to my Lexar iOS-compatible product?

This function will back up photos and videos that are stored in your camera roll, and contacts stored on your device. It will not back up any files saved in the app’s Internal Storage.

Do the camera setting controls on the Settings screen control my device’s camera?

The functions within Camera Settings on the app’s Settings screen control the settings for videos taken with the app camera only.

Automatic and Manual Backups

When running Auto Backup, will I be given the option to automatically delete the files after update?

No, the automatic backup function does not automatically delete files after backup. To do this, select manual backup of photos.

When doing a manual backup of photos on my iPhone and selecting 「Yes」 to the message asking whether I want to delete the photos after backup, why does the space available on my Internal Storage display not show a difference?

For safety and in case of accidental deletion, your iOS device keeps a folder in your Photo Album of 「Recently Deleted」 photos. Your deleted photos will be in this folder for 30 days, at which time they will expire. You can delete them immediately by navigating to the folder and selecting all (or some) of the photos and delete them immediately. Once the photos are removed completely from your device, you will notice the storage space percentage and free under Internal Storage on the Home screen will reflect the updated storage availability.

Music

Why can’t I move all of my music files to my external storage?

Only music files not protected by Digital Rights Management (DRM) can be managed with the Lexar Media Manager app. Files that are protected may show up on your music file list in the app, but they will appear greyed out, and you will not be able to select those files.

Encryption/Decryption

I’ve lost my password for File Lock (Encrypt) and/or App Lock. How do I retrieve it?

Your password is unique to you and Lexar does not keep a copy of it, so there is no way to retrieve a copy of it when it is lost. It’s a good idea to choose a password you know you’ll remember, or jot it down somewhere so you can access it if you forget it.

Additional Resources

I still have questions about the app. Where can I go for help?

You can download the full Lexar Media Manager User Guide, view warranty information, and find other support information at www.lexar.com/support

讀卡機

Lexar® Professional Workflow產品系列讀卡機常見問題

關於產品

什麼是 Lexar^® Professional Workflow 系列?

使用完全可定制的Lexar Professional Workflow產品系列可一次性傳輸多張卡中的文件。該系列產品包括兩款四槽集線器（Thunderbolt™ 2/USB 3.0或USB 3.0）、一組讀卡機（SDHC™/SDXC™ UHS-II、CompactFlash® UDMA 7、XQD™ 2.0、CFast™ 2.0和microSDHC™/microSDXC™ UHS-II）以及一款雙端口USB 3.0集線器。其創新的模塊化設計讓您能夠實現定制設置，而其高速性能又讓您能快速卸載您的工作。

該系列中提供哪些產品？

四槽集線器：
Lexar Professional Workflow HR1（四槽USB 3.0讀卡機集線器）

- 讀卡機
- Thunderbolt 線纜
- USB 3.0 線纜

USB 3.0 集線器:

Two-port USB 3.0 集線器
USB 3.0 線纜

使用帶讀卡機的集線器的速度優勢是什麼？

使用USB 3.0端口時，Lexar Professional Workflow在USB 3.0的速度下提供高速文件傳輸。吞吐量完全取決於系統規格，包括硬碟寫入速度、處理器速度、存儲和操作系統（更不用說傳輸來源記憶卡的讀取速度）。所有這些變量使其很難引用實際性能等級。但是，使用裝備先進的計算機和傳輸速度快的記憶卡時，可獲得最佳性能。

而使用Thunderbolt 2集線器，還可獲得更快的性能。理論極限將USB 3.0確定為5gbps，將Thunderbolt 2確定為20gbps。因此，根據上面所列的所有輸入，通常可獲得高達4倍的性能。根據卡速度和計算機系統規格的不同，性能可能有很大的差異。

在設置中包括集線器為何比使用獨立單槽讀卡機更好？

主要優勢在於能夠一次性傳輸多個卡中的數據（同時傳輸），節約了時間。而使用單槽讀卡機，一次僅可傳輸一個卡中的內容（連續傳輸）。集線器全部填充所選的讀卡機或集線器模塊時，可更快地卸載工作。這樣您可以更快地進行編輯、分享，最終再回到拍攝。

我能否混合搭配所需的讀卡機？

能，這是使用Lexar Professional Workflow系列的最大優勢之一 — 根據您的特定需求設計自定義設置。例如，Nikon D4拍攝者可能需要兩個CompactFlash (CF)讀卡機和兩個XQD 2.0讀卡機，而Canon 5D Mark III拍攝者可能需要三個CF讀卡機和一個SD UHS-II讀卡機。其他拍攝者可能需要一個或多個雙端口USB 3.0集線器作為其工作流程設置的一部分。

該系列產品適用於哪些人？

該產品系列設計時考慮了專業攝影師、攝像師和愛好者。對於使用多張卡拍攝，或使用多個攝像機/攝影機的人來說，堪稱最佳選擇。如今的攝像機能夠拍攝RAW圖像、高分辨率照片、4K視頻等等，因此需要更快、更高容量的記憶卡，以及更快地從多張卡傳輸大量數據。現在，這些功能可以兼顧。雙端口USB 3.0模塊允許您連接USB隨身碟或其他讀卡機，甚至為這些設備充電。

設置和使用

我能否使用Professional Workflow HR1和HR2隨附的電源適配器？

否，Professional Workflow HR2集線器需要更高的功率，因此隨附更大的電源。請勿混用不同設備的電源。

沒有集線器能否使用讀卡機？

能，每個讀卡機包裝都包括USB線纜，可單獨使用。這使其成為出色的即時解決方案。

沒有HR1和HR2集線器，能否使用讀卡機和雙端口USB 3.0集線器模塊？

能，每個模塊包裝都包括USB線纜，可單獨使用。這使其成為出色的即時解決方案。

使用Professional Workflow HR2集線器，菊花鏈功能如何工作？

要方便地在產品系列中的任何地方以菊花鏈形式連接集線器，可在集線器背部使用兩個Thunderbolt 2端口。只需將集線器中的一根Thunderbolt 2線纜連接到計算機或其他設備，然後將集線器連接到下一個設備（如顯示器或硬碟）的Thunderbolt 2線纜即可。Thunderbolt 2技術支持將最多6個設備以菊花鏈形式連接到計算機的一個端口。要確保最佳性能，考慮將集線器放在菊花鏈的開頭，最靠近計算機的地方。

讀卡機上的LED為何閃爍？

這表示讀卡機正在將卡中的數據傳輸到計算機。當讀卡機的LED正在閃爍時，請勿移除卡或從集線器中移除讀卡機。

使用集線器時，有沒有任何建議的讀卡機特定配置？

如果攝影師和攝像師僅使用基於CompactFlash (CF)的攝像機拍攝，可能需要購買四個CF讀卡機。Nikon D5拍攝者可能需要兩個CF和兩個XQD 2.0讀卡機（假設他們使用攝像機中的兩個插槽）。Canon DSLR用戶可能需要CF和SD UHS-II讀卡機組合（因為有些佳能攝像機往往使用其中一種外形）。許多攝影師使用基於CF的攝像機作為主要攝像機，使用傻瓜相機用於一般用途或勘景。這些拍攝者也可能需要在集線器中組合使用CF和SD讀卡機。

為何使用USB type B連接器？

這種連接器持久耐用，可在集線器中順暢地插入和取出讀卡機。

故障排除

Professional Workflow HR1或HR2集線器是否需要插入交流電源才能工作？

是，必須插入交流電源，這兩個集線器才能正常工作。計算機上的USB端口提供的電源不足以為此設備供電。

我的Mac從休眠喚醒後，我為何收到一系列「隨身碟錯誤移除」消息？

有時，計算機喚醒後，可能無法識別集線器。如果出現這種情況，請從Mac中拔出HR1或HR2集線器，再插回。如果仍未解決問題，則可能需要重新啓動計算機。

若沒有提供符合我國監管指南的電源適配器，如何使用Professional Workflow HR1或HR2集線器？

我們一直盡可能多地提供特定地區適配器，但無法滿足每個國家/地區的需求。如果您在這些地區，可購買滿足您所在國家/地區的國際電源適配器需求的旅行轉換器，配合Professional Workflow Reader HR1或HR2集線器隨附的電源使用。請確保您購買的適配器符合您所在國家/地區的電源適配器指南要求。

我的計算機為何收到一條錯誤消息，通知我正在使用某一種Lexar Professional Workflow集線器，沒有足夠的電源來傳輸文件？

當電源線未連接到Professional Workflow HR1或HR2集線器，或電源未連接到牆壁插座或電源時，會發生此錯誤。正確連接集線器即可解決此錯誤。

兼容性和支持

Professional Workflow讀卡機支持哪些記憶卡格式？

目前，產品系列包括支持SD UHS-I和UHS-II、CompactFlash UDMA 7、CFast or CFast 2.0（Thunderbolt或USB 3.0）、XQD 2.0以及microSD UHS-I和UHS-II格式的讀卡機。關於通用性，CFast 2.0讀卡機與1.0格式（以1.0速度）向後兼容。隨著技術發展，我們會推出新的記憶卡格式，並為該產品系列創建新讀卡機。購買新的讀卡機格式有助於您的工作流程設置滿足未來需求，節約成本。

常見問題

為何內存對數碼相機至關重要？

隨著數碼相機圖片質量和分辨率的提高，對保存和存儲更大照片和視頻文件的需求也在增加。早期版本的數碼相機通常具有內置、不可擴展的內存，用於存儲圖片和視頻。這些相機的內存容量很快就會用光，用戶必須不斷將圖片下載到計算機或擦除圖片，然後才能繼續拍照。對於想用相機而附近沒有計算機的用戶，這很不方便。
今天的領先數碼相機製造商通常採用可移動數碼膠片卡來拍攝、存儲和交換圖像。常用可移動存儲解決方案包括SD、microSD、CompactFlash和CFast。通常，相機製造商會為相機隨附一個最小容量卡，內存剛好可為用戶提供良好的開箱即用體驗。當這張卡的容量用光時，用戶必須將照片下載到計算機，擦除圖片，或更換卡，才能繼續拍照。這就是為什麼對於許多典型的攝影場景，如度假、婚禮或體育賽事，數碼攝影師需要更多數碼膠片的原因。

今天的數碼膠片有哪些常見類型？

數碼膠片使用非易失性閃存，意味著不需要電源來存儲拍攝的圖片。閃存技術是需要便攜性和堅固性的應用的理想選擇。有三種主要類型的閃存可用於今天的數碼相機：
SD、microSD、CompactFlash和CFast格式。

Secure Digital (SD): 郵票大小的SD卡緊湊靈活，可用於多種消費類電子設備。它能夠提供高性能，幫助消費者通過可靠和易於使用的格式快速捕捉照片和視頻文件。

microSD: 可買到的最小記憶卡，大約是普通大小的SD卡的四分之一。microSD卡用於手機、平板電腦、運動型攝像機、無人機和其他移動設備。

CompactFlash: 外形尺寸小（約為火柴盒大小），將非易失性存儲、高容量選項和行業標準兼容性組合在一起，對於數碼相機和手持式計算設備必不可少。由於它們是按照CompactFlash協會制定的准則設計的，因此在所有認證的CompactFlash卡和任何符合CompactFlash標準的設備中建立了基本兼容性保證。

CFast:CompactFlash協會提供的卡格式的最新演變，最大傳輸速率高於CompactFlash®卡。CFast卡與CompactFlash卡大小類似，但沒有可能在連接器中彎曲的引腳。該格式主要設計用於支持下一代攝像機和DSLR相機的功能。

什麼是CompactFlash協會？

CompactFlash協會(CFA)於1995年成立，是非營利的互利行業協會。CFA的理念是CompactFlash技術將帶來一系列新的先進、小型、輕巧、低功耗移動產品，大幅提高生產力並改善數百萬人的生活方式。通過CompactFlash，可在各種數字系統之間輕鬆傳輸所有類型的數字信息和軟件。CFA的目標是促進和鼓勵全世界採用CompactFlash技術作為開放行業標準。

談到數碼膠片時，性能是否很重要？

隨著數碼相機應用、相機分辨率以及圖片和視頻文件大小不斷增加，讀寫大型文件的能力成為關鍵性能要求。改進寫入性能可大幅減少拍攝另一張照片前的等待時間（「圖像存儲時間」）。改進讀取性能可大幅減少將照片和視頻文件傳輸到計算機的等待時間——從而節約時間並改善數碼攝影「工作流程」。

Lexar SD、CompactFlash和CFast卡大幅減少了將文件傳輸至計算機的時間以及將圖片文件寫入卡中的時間。雖然實際性能會因相機型號而異，但Lexar的高速性能可確保您不會錯過任何精彩瞬間：嬰兒的微笑、婚禮之吻，或任何其他珍貴的時刻。

633x, 667x, 1000x, 1066x, 1667x, 1800x, 2000x and 3500x (1x=150KB/s)性能是什麼意思？

在合適的時刻拍攝合適的照片，數碼膠片的性能至關重要，Lexar為此實施了一個易於理解的系統，可指示記憶卡存儲數據的速度。該系統借鑒自CD-ROM行業，其中CD-ROM驅動器的性能以「x」為增量評級，1x等於每秒150KB (KB/s)的持續寫入速度能力。Lexar將繼續推出更高「x」等級的更快產品，讓消費者輕鬆識別最新的高性能數碼攝影。

633x = 讀取速度高達95MB/s，寫入速度略低
667x = 讀取速度高達100MB/s，寫入速度略低
1066x = 讀取速度高達160MB/s，寫入速度略低
1667x = 讀取速度高達250MB/s，寫入速度略低
1800x = 讀取速度高達270MB/s，寫入速度略低
2000x = 讀取速度高達300MB/s，寫入速度略低
3500x = 讀取速度高達525MB/s，寫入速度略低

Lexar SAFE S3000 and SAFE S3000 FIPS FAQs - Discontinued

What does SAFE stand for?

Secure Access For Enterprise

Why does Lexar offer multiple SAFE solutions?

Lexar® JumpDrive SAFE S3000 FIPS is specifically engineered for government, military, and enterprise users who require ultra high security to meet agency directives Lexar JumpDrive SAFE S3000 is designed for users looking for enterprise-level security that is scaled to meet the budget and performance demands of small businesses.

What makes Lexar JumpDrive SAFE unique?

Lexar JumpDrive SAFE combines 3 key elements to provide a secure flash drive.

A) Hardware-based AES 256-bit Encryption on all stored data
B) Tamper-proof smart card to manage all security critical computations
C) Rugged metal housing to protect against physical damage

What does FIPS stand for?

Federal Information Processing Standards. Publicly announced standards developed by the United States Federal government

Why does the Gemalto brand name appear on the application graphical user interface (GUI)?

Lexar JumpDrive SAFE is jointly developed by Lexar and Gemalto, combining Lexar’s secure solid state storage technology and Gemalto’s .NET smart card technology.

What is the difference between the Lexar JumpDrive SAFE S3000 and Lexar JumpDrive SAFE S3000 FIPS?

Does the encryption reduce the drive performance?

No, the hardware-based 256-bit AES engine performs on-the-fly encryption and does not impact performance.

Do I need to install a driver and/or software for Lexar JumpDrive SAFE?

No, the Lexar JumpDrive SAFE is fully plug and play and does not require any drivers or software to be installed on the host computer.

Do I need administrator privileges (on Operating Systems) for Lexar JumpDrive SAFE to work?

No, the Lexar JumpDrive SAFE does not require administrator privileges to work.

How does encryption protect my data?

All drive content is encrypted with the NIST standard AES encryption algorithm and stored in ciphered form on the flash memory. The encryption key used to perform the encryption is stored securely on the embedded tamper-proof smart card, protecting it from unauthorized access. Without the knowledge of the encryption key, it is exceedingly difficult to extract the data from the cipher, even if one is able to disassemble the drive to access the flash memory.

Why is hardware-based encryption more secure?

A software-based encryption runs on top, and utilizes the shared memory space of the computer operating system to store such contents as encryption keys. Other processes on the operating system may be able to access the same memory space, and in so doing, compromise security. A hardware-based encryption uses the memory space within the device itself, eliminating the risk of access by other processes external to the flash drive.

How does the smart card protect my data?

The smart card provides the following protection:

Tamper-proof storage: Smart cards provide a means of securely storing data on the card. This data can only be accessed through the smart card operating system with authorized access rights. This feature is utilized to store the encryption key, the login password, and the other security parameters.

Isolation of security-critical computations: Operations involving authentication, key generation, and storage are isolated from other parts of the device and host computer that do not have a 「need to know.」 These operations are all performed on the smart card only.

Strong Authentication: The smart card blocks access to JumpDrive SAFE after a predefined set of login attempts have exceeded. The smart card deploys a stringent PKI-based challenge-response process for authentication. This prohibits any unauthorized access to the flash encryption keys and protects the authorized user. The smart card protects against password dictionary attacks through an increasing delay after each incorrect attempt (before the next login can be attempted.)

Why is smart card-based authentication more secure than other methods of authentication?

The secure microcontrollers used in Gemalto smart cards have security features manufactured into the ICs that thwart attackers from accessing any sensitive information that is stored in the card. Gemalto smart card technology is extremely difficult to duplicate or forge and has built-in tamper protection. Smart card chips include a variety of hardware and software capabilities that detect and react to tampering attempts and help counter possible attacks. This reflects in Common Criteria level EAL 5+ certification achieved by the Gemalto smart card micro-controller. In addition, smart card technology provides secure hardware-based key generation and storage and standard PKI-based challenge-response process to unblock access. Gemalto smart card technology provides security benefits at a number of levels that other hardware-based authentication mechanisms cannot match.

How does the Lexar JumpDrive SAFE S3000 behave if it comes under a password dictionary attack?

The Lexar JumpDrive SAFE S3000 permits up to 5 login attempts. The Lexar JumpDrive SAFE S3000 also introduces an increasing delay after each incorrect attempt before the next login can be attempted. Once the attempts are exceeded, the device rejects further login attempts until the user provides the correct answer to the security question.

Are copies of the password and cryptographic key saved on the host computer?

No. Both the password and cryptographic key are stored securely only on the smart card.

What happens if I forget my password?

The Lexar JumpDrive SAFE S3000 allows password reset once the correct answer is provided to the security question. A new password must be set but no data is erased. If however a user forgets the answer to the security question and exceeds 5 login attempts, the Lexar JumpDrive SAFE S3000 becomes permanently disabled and cannot be recovered.

Does the Lexar JumpDrive SAFE S3000 perform any operations that leave traces on the host computer?

No. All operations are contained within the drive, leaving no trace on the host machine.

How are the encryption keys generated?

The encryption keys are generated by the smart card’s Random Number Generator (RNG) and are stored securely in the smart card’s non-volatile memory. The keys are not stored in the flash memory or the host computer, or transmitted across the USB port.

How is the Lexar JumpDrive SAFE S3000 password protected?

The login password is hashed before being transmitted to Lexar JumpDrive SAFE S3000, and then stored in the tamper-proof smart card. The password validation uses challenge-response process combining with zero-knowledge transfer mechanism. The authentication is performed on the smart card only; there is no way to retrieve the stored password from the smart card. Access is granted only when password has been validated by the smart card. If login attempts are exceeded, the device rejects further login attempts.

Does the Lexar JumpDrive SAFE S3000 support complex passwords?

The JumpDrive SAFE S3000 supports complex passwords, but does not enforce it. The main reason for a complex password is to deter software-based password dictionary attacks. The SAFE S3000 defeats such attacks with the smart card. The smart card permits only a limited number of login attempts and introduces an increasing delay after each incorrect attempt before the next login can be attempted.

How do I get the login application to start automatically?

Description

What are the file systems FAT32, NTFS, ExFAT, and Extended Journaled?

FAT32, ExFAT, NTFS, and Extended Journaled are some of the most common examples of file systems, which are methods by which data is arranged on a storage device. Very simply, the differences are as follows:

FAT32 – 4GB (gigabyte) maximum file size and maximum storage device size can be as low as 2TB (terabytes). Compatible with both Mac and Windows. Typically used for legacy Operating Systems and older devices.

ExFAT – A newer iteration of FAT32, requiring newer devices and operating systems, but effectively removing the file size limits and device size limits (ExFAT supports hundreds or thousands of terabytes).

NTFS – Windows-specific, though has limited support in OS X. Typically used on an fixed hard drive, rather than removable storage. Like ExFAT, has less restrictive file size limitations, but due to it’s status as a primarily Windows-based file system, NTFS can conflict with non-PC hardware.

Extended Journaled – Mostly Apple-specific when dealing with consumer products, and has limited support outside OS X/iOS platforms. Typically used as an Apple OS drive, with removable storage being formatted as FAT32/ExFAT instead.

For best compatibility and interoperability of your Lexar storage product across multiple devices (especially non-PC devices, such as media readers built into TVs, Blu-Ray players, DVRs, etc.), we recommend formatting your device as ExFAT or FAT32. Specific hardware may require other file systems, however, including ones not listed here. For more information on a given device’s needs, please see your device’s documentation or manufacturer support for more details.

How to format a flash-based storage device in OS X
