金士顿固态硬盘 – 您需要了解的全部内容

Trim 和垃圾回收是现代 SSD 采用的技术,用于改善性能和耐用性。当 SSD 刚刚从箱中取出时,所有 NAND 块都是空的,因此 SSD 可以通过一次操作将新数据写入空块。随着时间推移,所有空块会被使用并包含用户数据。为了向已用块写入新数据,SSD 将被强制执行读取-修改-写入周期。读取-修改-写入周期会降低 SSD 整体性能,因为 SSD 现在必须执行三次操作,而非一次。读取-修改-写入周期还会导致写入放大,从而降低 SSD 整体耐用性。

Trim 和垃圾回收可以联合释放已用块,从而改善 SSD 性能和耐用性。垃圾回收是 SSD 控制器内置的一项功能,用于整合已用块中的数据,以释放更多空块。此流程在后台进行,完全由 SSD 自己操作。不过,SSD 可能不知道哪些块包含用户数据,哪些块包含用户已删除的陈旧数据。这正是 Trim 发挥作用的地方。Trim 允许操作系统让 SSD 了解数据已被删除,因此 SSD 可以释放之前的已用块。要让 Trim 正常运行,操作系统和 SSD 必须都支持 Trim。目前,多数现代操作系统和 SSD 支持 Trim,不过多数 RAID 配置不支持 Trim。

金士顿 SSD 充分利用了垃圾回收和 Trim 两项技术,可在 SSD 整个生命周期内保持尽可能高的性能和耐用性。

Part Specific FAQs

确保 M.2 接口采用的是 M 键锁。Predator M.2 卡不能用于采用 B 键锁的 M.2 接口(见下图)。因为只有采用 M 键锁的 M.2 接口支持 PCIe x4。

FAQ: KSD-032015-PRE-01

该适配器适合 PCIe x4、x8 和 x16 接口,不能使用 PCIe x1 接口和老的 PCI 接口。

FAQ: KSD-032015-PRE-02

试试将 BIOS 恢复为默认设置。检查确认 M.2 接口已启用。有些情况下,M.2 接口与 PCIe 接口共享。您需要从中选择一个。如果都不起作用,请检查 BIOS 是否有更新。更新后需要将 BIOS 恢复默认设置。

FAQ: KSD-032015-PRE-03

要使此卡以最高速度运行,您的 M.2 接口必须至少兼容第二代 PCIe x4 接口。该固态硬盘可使用 M.2 PCIe x1 或 x2 接口,但速度较低。另外,请确保在 BIOS 中将 M.2 插槽作为 x4 接口与 PCIe 总线关联。

FAQ: KSD-032015-PRE-04

可以,但您无法将其设置为启动盘。

FAQ: KSD-032015-PRE-05

某些主板需要在 BIOS 中启用“兼容支持模块 (CSM)”后才可通过 PCIe SSD 进行启动。默认情况下已启用此模块。如果已禁用,请按照 BIOS 说明解决该问题,也可参阅主板制造商说明文件。

OS/Compatibility FAQs

During the OS installation, go to UTILITIES / TERMINAL 

In terminal type: 

diskutil list 

Then press RETURN. Scroll up to top and verify the Kingston SSD disk (i.e. disk0, disk1, etc).

Then type: 

diskutil mountDISK disk0 (or whichever ddisk is the Kingston SSD). 

Then press RETURN. It should show "mounted successfully".

Then type: 

diskutil eraseDISK apfs YOURDRIVENAME disk0 (or whichever disk is the Kingston SSD) 

Warning – This step (eraseDISK command) will delete all data on the target drive. Confirm that you have selected the drive you wish to delete and then continue. 

Then press RETURN. It should show "successful". Then exit terminal and proceed with the normal installation of the OS. FAQ: KSD-092917-GEN-21

静电放电 (ESD) 就是指积聚的静电放电的过程。 不应忽视静电放电,因为这是会导致计算机或硬件组件被人为损坏或毁坏的为数不多的几种方式之一。 就像脚在地毯上摩擦之后,再触摸金属物质时有可能会出现静电放电。 静电放电发生时,用户不一定会感受到触电,并且只有在计算机内部操作或移动硬件时才会发生。

如何防止静电放电
防止静电放电的最佳方法是使用静电放电腕带、接地垫或接地工作台。 但是,由于大多数用户都没有这些装置,我们罗列了以下步骤来尽可能降低发生静电放电的几率。

  • 站立 – 我们建议您在计算机上工作时保持站立。 坐在椅子上会产生更多静电。
  • 线缆 - 确保计算机背面的所有线缆都已被拔下(电源线、鼠标、键盘等)。
  • 衣服 - 确保不要穿着会产生大量静电的衣物,如毛衣。
  • 配饰 - 为了减少静电放电和防止其他问题,最好取下所有的首饰。
  • 天气 - 雷暴天气会增加静电放电的风险;除非绝对必要,否则不要在雷暴天气时,在计算机上工作。 在十分干燥的地区,每次有气流(风、空调、鼓风机)经过绝缘表面时,空气本身就会成为静电积聚机制的一部分。 不要被高湿度所误导,并注意连接处以及其他电气接口的腐蚀问题。

Secure Erase User Guide for Linux
This guide will walk you through securely erasing your Kingston SSD using Linux tools

SATA Secure Erase Procedure

Warning
Please make sure to have a full backup of any important data before you proceed!

Prerequisites
• You must have root privileges.
• You must have your SSD connected to the system as a secondary (non-OS) drive.
• You must have lsscsi and hdparm installed. You may need to install them with your distribution’s package manager.
• Your drive must not be in a security freeze.
• Your drive must not be password protected.

Instructions
1. Find the device name (/dev/sdX) of the drive you wish to erase:
# lsscsi

2. Make sure drive security is not frozen:
# hdparm -I /dev/sdX | grep frozen

If the output shows "frozen" (instead of "not frozen") then you cannot continue to the next step. You must try to remove the security freeze by trying one of the following methods:

Method 1: Put the system to sleep (suspend to RAM) and wake it up. On most distributions the command to suspend is:
# systemctl suspend

Now issue the hdparm command again. If it worked the output will show “not frozen” (instead of “frozen”).
Method 2: Hot plug the drive. This is done by physically unplugging the SATA power cable from the drive and plugging it back in while the system is powered on. You may need to enable hot plug in BIOS. Not all systems support hot plug.

Now issue the hdparm command again. If it worked the output will show “not frozen” (instead of “frozen”).

3. Set a user password on the drive. The password can be anything. Here we are setting the password to “p”:
# hdparm --security-set-pass p /dev/sdX

4. Issue the secure erase command to the drive using the same password:
# hdparm --security-erase p /dev/sdX

This command may take a few minutes to complete. The drive password is removed upon successful completion.
If the secure erase is interrupted or otherwise fails your drive may become security locked. In this case you can remove the security lock using the command below and then try the secure erase procedure again:
# hdparm --security-disable p /dev/sdX

NVMe Secure Erase Procedure

Warning
Please make sure to have a full backup of any important data before you proceed!

Prerequisites
• You must have root privileges.
• You must have your SSD connected to the system as a secondary (non-OS) drive.
• You must have nvme-cli installed. You may need to install it with your distribution’s package manager.
• Your drive must not be password protected.

Instructions
1. Find the device name (/dev/nvmeXn1) of the drive you wish to erase:
# nvme list

2. Issue the format command to the drive. Here we set the secure erase setting to 1 which indicates a user data erase:
# nvme format /dev/nvmeXn1 --ses=1

This command may take a few minutes to complete.
