SSD

SSD硬盘和HDD硬盘有何区别？

SSD和HDD的最大区别之一是SSD硬盘没有移动部件。由于没有移动部件，SSD硬盘的速度更快，更安静，抗冲击力和抗震力也更强。

如何在计算机中安装SSD硬盘？

请参阅快速入门指南，网址： https://www.lexar.com/cn/support/downloads/

安装SSD之前是否需要安装驱动程序？

一般来讲，如果SSD支持SATA接口，则Windows 7和10中内置驱动程序。无需安装任何第三方驱动程序。
如果SSD支持PCIe，则必须在Windows 7中安装NVMe驱动程序。Windows 10具有PCIe SSD的本地驱动程序。

什么是“S.M.A.R.T”？如何检查SSD的S.M.A.R.T？

S.M.A.R.T代表“Self-Monitor and Report Technology”（自我监测和报告技术），内置在硬盘和固态硬盘中以指示硬盘状态。所有Lexar SSD系列都支持S.M.A.R.T，并且Lexar提供的SSD Dash工具可在Lexar官网上免费下载，以帮助用户轻松获取S.M.A.R.T值。S.M.A.R.T包含平均P/E周期计数、总通电时间、通电周期计数、总主机写入/读取数和其他特定信息。

购买新的SSD时，如何将操作系统和数据保留在原始硬盘中？

建议采用系统克隆方式将操作系统传输至SSD。它将保留计算机所需的所有数据、设置和驱动程序。要克隆硬盘，Lexar建议使用EaseUS Todo Backup作为助理，更多详情请访问https://www.easeus.com/ 。

什么是“垃圾回收”？

在SSD中，会在使用过程中产生大量分散数据块。垃圾回收（所谓的GC）机制将这些数据块移至特定物理单元，然后重新使用原始单元存储新数据。垃圾回收是必要的，并可提高SSD的整体性能。Lexar优化高效GC的算法以确保SSD运行顺畅。

什么是“Trim”？Trim和垃圾回收之间的关系是什么？

TRIM是OS（操作系统）命令集，在Windows 7中开始支持。当用户删除文件时，OS发送TRIM以通知SSD此删除操作，然后SSD将特定存储单元标记为无效状态。一旦GC操作，GC就可以更准确高效地擦除存储单元，无需在闪存中重新分配数据。

什么是“M.2”？

M.2称为NGFF（Next Generation Form Factor，下一代外形规范），允许将功能扩展、收缩和高度集成到单个外形规范中。SSD是采用M.2的设备之一，轻薄紧凑，可灵活适应不同的设备。

为何我的性能基准与期望值不同？

测试值因不同基准工具而异。
工具的版本也对测试结果有影响。
平台可能也会影响结果。一般而言，在高端平台上的性能会更好。
如果SSD被使用过，里面包含数据，则可能会有点慢。

即使在相同的条件下，单个测试的结果也有细微差别。

如何检查计算机是否兼容可使用M.2 Pcle SSD？

M.2插槽可能仅支持SATA协议。购买M.2 PCIe SSD前，请联系服务中心或访问PC/笔记本电脑/主板制造商网址，获取详细规范。

SSD需要进行碎片整理吗？

SSD具有耗损均衡机制。此机制可确保每单个物理存储单元都获得相同的P/E周期。它旨在延长工作寿命。不需要碎片整理。

修改或篡改SSD硬盘会使保修失效吗？

修改或篡改SSD硬盘会使保修失效。

NVMe M.2 SSD硬盘是否适用于任何M.2插槽？

否，请验证您的笔记本电脑或台式机是否支持NVMe SSD硬盘。

SD/microSD

什么是 SD UHS?

UHS 是超高速度（Ultra High Speed）的英文缩写，指的是 SDHC 存储卡和 SDXC 存储卡提高总线接口速度的新技术。
UHS-I最高传输速度（理论值）为104MB/s，支持UHS的SDHC/SDXC存储卡读写性能可提升至104MB/s。UHS-I 可使接口速度达到每秒104MB，而支持 UHS 的 SDHC 卡或 SDXC 卡的传输性能可提升至每秒104MB。
UHS-II是新一代UHS。 UHS-II将接口速度提高到312MB / s。比UHS-I快3倍。

*资料来源：SD协会

什么是 U1/U3 速度等级？

有些新的UHS存储卡会标称U1速度，这表示该UHS-I具备U1速度等级，代表录制视频内容最低写入速度为10MB/s。值得注意的是，虽然U1速度等级与Class 10的速度相同，但二者测试方式不同，符合其中一种速度等级并不意味着同时也符合另外一种速度等级。U3 标记意味着存储卡性能需要达每秒30MB才能满足4K分辨率的录制和播放。

什么是 V30/V60/V90视频速度等级？

它代表视频录制与写入恒定速度的分级。分为三种速度等级，“速度等级”，“UHS速度等级”和“视频速度等级”。此速度等级通过指定最低写入性能来提供视频记录所需的恒定速度。这包括V6，V10，V30，V60和V90。 V6 Speed Class意味着存储卡的最低写入速度需要达到每秒6MB，V10为每秒10MB，30为每秒30MB，依此类推。

V60和V90可应用于高分辨率和高质量的8K视频录制，V30可应用于4K分辨率。

SD卡制造商会在其存储卡(SDHC，SDXC，UHS-I，UHS-II和其他SD存储卡等)打印上这些速度等级（V60，V90等）。用户可依照不同速度等级挑选最符合使用需求的存储卡。

*资料来源：SD协会

什么是A1 / A2应用性能等级？

它用于智能手机应用程序性能分类。应用程序性能等级1（A1）和等级2（A2）定义随机读/写IOPS的最小平均值。 A1的IOPS规格读取1500IOPS /写入500IOPS，最小持续顺序性能为10MB / s。 A2的IOPS规格比A1快几倍。随机读取为4000IOPS，随机写入为4000IOPS。这意味着A2的写入性能比A1读取性能快，并且最小持续顺序性能也是10MB / s。

USB3.0能够向下兼容USB2.0规格，故不影响读写数据的功能，但将USB3.0 U盘使用在USB2.0插槽上会受到传输速度的限制。

要如何查看我的U盘容量呢?

请至「我的计算机」中，在U盘图标上点右键再点选「内容」，即会显示随身碟装置的容量。
亦可透过「计算机管理」中的「磁盘管理」来确认U盘的容量。（不同电脑系统，功能名称可能不同）

U盘是通过什么方式来储存数据?

U盘是透过NAND Flash当作储存数据的组件，NAND Flash透过充电以及放电(写入/抹除)的方式来存放数据这类储存装置拥有比传统硬盘重量轻、体积小、省电、不怕震动以及效能更好等优势。

如何更改U盘的名称?

在U盘图标点选右键「重新命名」即可更改U盘名称，或透过格式化的方式在「磁盘区卷标」的字段更改名称，格式化前请先将数据备份，以免数据因格式化被删除。

在传输数据的过程中不小心拔掉U盘会发生什么事?

请注意避免在数据传输过程中拔掉U盘，这样的动作会造成档案在传输过程中数据遗失，甚至可能造成U盘的功能异常。
若使用完U盘，请先「安全的移除装置」再将U盘拔除插槽。

Will the Lexar Media Manager app work with other manufacturer’s flash drives?

No, the Media Manager app will only work with Lexar products.

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

使用带读卡器的集线器的速度优势是什么？

使用USB 3.0端口时，Lexar Professional Workflow在USB 3.0的速度下提供高速文件传输。吞吐量完全取决于系统规格，包括硬盘写入速度、处理器速度、存储和操作系统（更不用说传输来源存储卡的读取速度）。所有这些变量使其很难引用实际性能等级。但是，使用装备先进的计算机和传输速度快的存储卡时，可获得最佳性能。

而使用Thunderbolt 2集线器，还可获得更快的性能。理论极限将USB 3.0确定为5gbps，将Thunderbolt 2确定为20gbps。因此，根据上面所列的所有输入，通常可获得高达4倍的性能。根据卡速度和计算机系统规格的不同，性能可能有很大的差异。

在设置中包括集线器为何比使用独立单槽读卡器更好？

主要优势在于能够一次性传输多个卡中的数据（同时传输），节约了时间。而使用单槽读卡器，一次仅可传输一个卡中的内容（连续传输）。集线器全部填充所选的读卡器或集线器模块时，可更快地卸载工作。这样您可以更快地进行编辑、分享，最终再回到拍摄。

我能否混合搭配所需的读卡器？

能，这是使用Lexar Professional Workflow系列的最大优势之一 — 根据您的特定需求设计自定义设置。例如，Nikon D4拍摄者可能需要两个CompactFlash (CF)读卡器和两个XQD 2.0读卡器，而Canon 5D Mark III拍摄者可能需要三个CF读卡器和一个SD UHS-II读卡器。其他拍摄者可能需要一个或多个双端口USB 3.0集线器作为其工作流程设置的一部分。

该系列产品适用于哪些人？

该产品系列设计时考虑了专业摄影师、摄像师和爱好者。对于使用多张卡拍摄，或使用多个摄像机/摄影机的人来说，堪称最佳选择。如今的摄像机能够拍摄RAW图像、高分辨率照片、4K视频等等，因此需要更快、更高容量的存储卡，以及更快地从多张卡传输大量数据。现在，这些功能可以兼顾。双端口USB 3.0模块允许您连接USB闪存盘或其他读卡器，甚至为这些设备充电。

设置和使用

我能否使用Professional Workflow HR1和HR2随附的电源适配器？

否，Professional Workflow HR2集线器需要更高的功率，因此随附更大的电源。请勿混用不同设备的电源。

没有集线器能否使用读卡器？

能，每个读卡器包装都包括USB线缆，可单独使用。这使其成为出色的即时解决方案。

没有HR1和HR2集线器，能否使用读卡器和双端口USB 3.0集线器模块？

能，每个模块包装都包括USB线缆，可单独使用。这使其成为出色的即时解决方案。

使用Professional Workflow HR2集线器，菊花链功能如何工作？

要方便地在产品系列中的任何地方以菊花链形式连接集线器，可在集线器背部使用两个Thunderbolt 2端口。只需将集线器中的一根Thunderbolt 2线缆连接到计算机或其他设备，然后将集线器连接到下一个设备（如显示器或硬盘）的Thunderbolt 2线缆即可。Thunderbolt 2技术支持将最多6个设备以菊花链形式连接到计算机的一个端口。要确保最佳性能，考虑将集线器放在菊花链的开头，最靠近计算机的地方。

读卡器上的LED为何闪烁？

这表示读卡器正在将卡中的数据传输到计算机。当读卡器的LED正在闪烁时，请勿移除卡或从集线器中移除读卡器。

使用集线器时，有没有任何建议的读卡器特定配置？

如果摄影师和摄像师仅使用基于CompactFlash (CF)的摄像机拍摄，可能需要购买四个CF读卡器。Nikon D5拍摄者可能需要两个CF和两个XQD 2.0读卡器（假设他们使用摄像机中的两个插槽）。Canon DSLR用户可能需要CF和SD UHS-II读卡器组合（因为有些佳能摄像机往往使用其中一种外形）。许多摄影师使用基于CF的摄像机作为主要摄像机，使用傻瓜相机用于一般用途或勘景。这些拍摄者也可能需要在集线器中组合使用CF和SD读卡器。

为何使用USB type B连接器？

这种连接器持久耐用，可在集线器中顺畅地插入和取出读卡器。

故障排除

Professional Workflow HR1或HR2集线器是否需要插入交流电源才能工作？

是，必须插入交流电源，这两个集线器才能正常工作。计算机上的USB端口提供的电源不足以为此设备供电。

我的Mac从休眠唤醒后，我为何收到一系列“闪存盘错误移除”消息？

有时，计算机唤醒后，可能无法识别集线器。如果出现这种情况，请从Mac中拔出HR1或HR2集线器，再插回。如果仍未解决问题，则可能需要重新启动计算机。

若没有提供符合我国监管指南的电源适配器，如何使用Professional Workflow HR1或HR2集线器？

我们一直尽可能多地提供特定地区适配器，但无法满足每个国家/地区的需求。如果您在这些地区，可购买满足您所在国家/地区的国际电源适配器需求的旅行转换器，配合Professional Workflow Reader HR1或HR2集线器随附的电源使用。请确保您购买的适配器符合您所在国家/地区的电源适配器指南要求。

我的计算机为何收到一条错误消息，通知我正在使用某一种Lexar Professional Workflow集线器，没有足够的电源来传输文件？

当电源线未连接到Professional Workflow HR1或HR2集线器，或电源未连接到墙壁插座或电源时，会发生此错误。正确连接集线器即可解决此错误。

兼容性和支持

Professional Workflow读卡器支持哪些存储卡格式？

目前，产品系列包括支持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格式的读卡器。关于通用性，CFast 2.0读卡器与1.0格式（以1.0速度）向后兼容。随着技术发展，我们会推出新的存储卡格式，并为该产品系列创建新读卡器。购买新的读卡器格式有助于您的工作流程设置满足未来需求，节约成本。

Professional Workflow XR2 (XQD 2.0)读卡器能否读取我的第一代XQD卡？

不能。XQD 2.0读卡器与XQD 1.0格式卡不向后兼容。XQD 2.0存储卡可通过卡标签上的盒式USB徽标识别。

Professional Workflow SR2 (SD UHS-II)读卡器能否与SD UHS-I存储卡配合使用？

能，该读卡器完全与SD UHS-I卡（以UHS-I速度）向后兼容，因此SD UHS-I和UHS-II卡均可与读卡器配合使用。

能否使用Professional Workflow UR2读卡器同时传输三个microSD卡中的数据？

能，如果使用随附的USB 3.0线缆将读卡器直接插入计算机，则可同时传输每张卡中的数据。使用Professional Workflow HR2（高速Thunderbolt 2）或HR1 (USB 3.0)集线器也可以执行此操作。

常见问题

为何内存对数码相机至关重要？

随着数码相机图片质量和分辨率的提高，对保存和存储更大照片和视频文件的需求也在增加。早期版本的数码相机通常具有内置、不可扩展的内存，用于存储图片和视频。这些相机的内存容量很快就会用光，用户必须不断将图片下载到计算机或擦除图片，然后才能继续拍照。对于想用相机而附近没有计算机的用户，这很不方便。
今天的领先数码相机制造商通常采用可移动数码胶片卡来拍摄、存储和交换图像。常用可移动存储解决方案包括SD、microSD、CompactFlash和CFast。通常，相机制造商会为相机随附一个最小容量卡，内存刚好可为用户提供良好的开箱即用体验。当这张卡的容量用光时，用户必须将照片下载到计算机，擦除图片，或更换卡，才能继续拍照。这就是为什么对于许多典型的摄影场景，如度假、婚礼或体育赛事，数码摄影师需要更多数码胶片的原因。

今天的数码胶片有哪些常见类型？

数码胶片使用非易失性闪存，意味着不需要电源来存储拍摄的图片。闪存技术是需要便携性和坚固性的应用的理想选择。有三种主要类型的闪存可用于今天的数码相机：
SD、microSD、CompactFlash和CFast格式。

Secure Digital (SD): 邮票大小的SD卡紧凑灵活，可用于多种消费类电子设备。它能够提供高性能，帮助消费者通过可靠和易于使用的格式快速捕捉照片和视频文件。

microSD: 可买到的最小存储卡，大约是普通大小的SD卡的四分之一。microSD卡用于手机、平板电脑、运动型摄像机、无人机和其他移动设备。

CompactFlash: 外形尺寸小（约为火柴盒大小），将非易失性存储、高容量选项和行业标准兼容性组合在一起，对于数码相机和手持式计算设备必不可少。由于它们是按照CompactFlash协会制定的准则设计的，因此在所有认证的CompactFlash卡和任何符合CompactFlash标准的设备中建立了基本兼容性保证。

CFast:CompactFlash协会提供的卡格式的最新演变，最大传输速率高于CompactFlash®卡。CFast卡与CompactFlash卡大小类似，但没有可能在连接器中弯曲的引脚。该格式主要设计用于支持下一代摄像机和DSLR相机的功能。

什么是CompactFlash协会？

CompactFlash协会(CFA)于1995年成立，是非营利的互利行业协会。CFA的理念是CompactFlash技术将带来一系列新的先进、小型、轻巧、低功耗移动产品，大幅提高生产力并改善数百万人的生活方式。通过CompactFlash，可在各种数字系统之间轻松传输所有类型的数字信息和软件。CFA的目标是促进和鼓励全世界采用CompactFlash技术作为开放行业标准。

谈到数码胶片时，性能是否很重要？

随着数码相机应用、相机分辨率以及图片和视频文件大小不断增加，读写大型文件的能力成为关键性能要求。改进写入性能可大幅减少拍摄另一张照片前的等待时间（“图像存储时间”）。改进读取性能可大幅减少将照片和视频文件传输到计算机的等待时间——从而节约时间并改善数码摄影“工作流程”。

Lexar SD、CompactFlash和CFast卡大幅减少了将文件传输至计算机的时间以及将图片文件写入卡中的时间。虽然实际性能会因相机型号而异，但Lexar的高速性能可确保您不会错过任何精彩瞬间：婴儿的微笑、婚礼之吻，或任何其他珍贵的时刻。

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.

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
