-Use this Linux command-line tool to learn more about your NVMe drives
-======
-The nvme-cli command has lots of useful options, and it's a great way to
-take control of how you manage your data.
-![Command line prompt][1]
-
-NVMe stands for _Non-Volatile Memory Express_, and it refers to how software and storage communicate across PCIe and other protocols, including TCP. It's an [open specification][2] led by a non-profit organization and defines several forms of solid-state storage.
-
-My laptop has an NVMe drive, as does my desktop. And they're fast. I love how quickly my computers boot and how quickly they're able to read and write data. There's no perceptible delay.
-
-It also didn't take long for me to get curious about the technology driving this ultra-fast storage, so I did a little investigation. I learned that NVMe drives consume less power while delivering much faster access to data compared to even SSD drives over SATA. That was interesting, but I wanted to know more about my particular NVMe drives, and I wanted to know how they compared with other drives. Could I securely erase the drive? How could I check its integrity?
-
-Those questions led me to an Internet search that yielded an open source project with a collection of tools to manage NVMe drives. It's called [nvme-cli][3].
-
-### Install nvme-cli
-
-You can install `nvme-cli` from your distribution's package manager. For instance, on Fedora, CentOS, or similar:
-
-
-```
-`$ sudo dnf install nvme-cli`
-```
-
-On Debian, Mint, Elementary, and similar:
-
-
-```
-`$ sudo apt install nvme-cli`
-```
-
-### Exploring an NVMe drive
-
-After installing `nvme-cli` for my distribution, I wanted to explore my drive. There's no man page for `nvme-cli`, but you can get lots of help by entering `nvme help`:
-
-
-```
-$ nvme help
-nvme-1.14
-usage: nvme <command> [<device>] [<args>]
-
-The '<device>' may be either an NVMe character device (ex: /dev/nvme0) or an
-nvme block device (ex: /dev/nvme0n1).
-
-The following are all implemented sub-commands:
- list List all NVMe devices and namespaces on machine
- list-subsys List nvme subsystems
- id-ctrl Send NVMe Identify Controller
- id-ns Send NVMe Identify Namespace, display structure
- id-ns-granularity Send NVMe Identify Namespace Granularity List, display structure
- list-ns Send NVMe Identify List, display structure
- list-ctrl Send NVMe Identify Controller List, display structure
- nvm-id-ctrl Send NVMe Identify Controller NVM Command Set, display structure
- primary-ctrl-caps Send NVMe Identify Primary Controller Capabilities
-[...]
-```
-
-### List all NVMe drives
-
-The `sudo nvme list` command lists all NVMe devices and namespaces on your machine. I used it and found an NVMe drive at `/dev/nvme0n1`. Here is the output:
-
-
-```
-$ sudo nvme list
-
-Node SN Model Namespace Usage Format FW Rev
-
-\--------------------- -------------------- ---------------------------------------- --------- -------------------------- ---------------- --------
-
-/dev/nvme0n1    S42GMY9M141281 SAMSUNG MZVLB256HAHQ-000L7 1
-
-214.68 GB / 256.06 GB 512  B + 0 B 0L2QEXD7
-```
-
-I have a drive called `nvme0n1`. It lists the serial number, brand, size, firmware revision, and so on.
-
-You can get even more information about the drive and the features it supports by using the `id-ctrl` subcommand:
-
-
-```
-$ sudo nvme id-ctrl /dev/nvme0n1
-NVME Identify Controller:
-vid : 0x144d
-ssvid : 0x144d
-sn : S42GMY9M141281
-mn : SAMSUNG MZVLB256HAHQ-000L7
-fr : 0L2QEXD7
-rab : 2
-ieee : 002538
-cmic : 0
-mdts : 9
-cntlid : 0x4
-ver : 0x10200
-rtd3r : 0x186a0
-rtd3e : 0x7a1200
-[...]
-```
-
-### Drive health
-
-You can read about the overall health of a drive with the `smart-log` subcommand:
-
-
-```
-$ sudo nvme smart-log /dev/nvme0n1
-Smart Log for NVME device:nvme0n1 namespace-id:ffffffff
-critical_warning : 0
-temperature : 21 C
-available_spare : 100%
-available_spare_threshold : 10%
-percentage_used : 2%
-endurance group critical warning summary: 0
-data_units_read : 5,749,452
-data_units_written : 10,602,948
-host_read_commands : 77,809,121
-host_write_commands : 153,405,213
-controller_busy_time : 756
-power_cycles : 1,719
-power_on_hours : 1,311
-unsafe_shutdowns : 129
-media_errors : 0
-num_err_log_entries : 1,243
-Warning Temperature Time : 0
-Critical Composite Temperature Time : 0
-Temperature Sensor 1 : 21 C
-Temperature Sensor 2 : 22 C
-Thermal Management T1 Trans Count : 0
-Thermal Management T2 Trans Count : 0
-Thermal Management T1 Total Time : 0
-Thermal Management T2 Total Time : 0
-```
-
-This provides you with the drive's current temperature, the hours of use it's had so far, how many times it was unsafely shut down, and so on.
-
-### Formatting an NVMe drive
-
-You can format an NVMe drive with `nvme-cli`, but beware: This erases all of the data on the drive! If there's important data on your drive, you _must_ back it up before doing this, or else you **will** lose data. The subcommand is `format`:
-
-
-```
-`$ sudo nvme format /dev/nvme0nX`
-```
-
-(For safety, I've replaced the actual location of the drive with **X** to prevent copy-paste mishaps. Change the **X** to **1** or the appropriate location as listed in the results of `nvme list`.)
-
-### Securely erasing an NVMe drive
-
-When you get ready to sell or dispose of your NVMe computer, you probably want to erase the drive securely. The same warnings apply here as with the format process: Back up important data first because this command erases it!
-
-
-```
-`$ sudo nvme sanitize /dev/nvme0nX`
-```
-
-### Try nvme-cli
-
-The `nvme-cli` command is released under a [GPLv2][4] license. It's a robust command with lots of useful options, and it's a great way to take control of how you manage your data.

+
+使用这个 Linux 命令行工具来了解你的 NVMe 驱动器的更多信息
+======
+nvme-cli 命令有很多有用的选项，且它是一个很好的方式来控制你如何管理你的数据。
+![Command line prompt][1]
+
+NVMe 是指 _Non-Volatile Memory_（非易失性内存主机控制器接口规范），它指的是软件和存储如何通过 PCIe 和其他协议（包括 TCP）进行通信。它是一个由非营利组织领导的[开放规范][2]，并定义了几种形式的固态存储。
+
+我的笔记本电脑有一个 NVMe 驱动器，我的台式机也有。而且它们的速度很快。我喜欢我的电脑启动的速度，以及它们读写数据的速度。没有可察觉的延迟。
+
+没过多久，我就对驱动这种超高速存储的技术产生了好奇，所以我做了一些调查。我了解到，NVMe 驱动器消耗的电力更少，而提供的数据访问速度甚至比 SATA 的 SSD 驱动器快得多。这很有趣，但我想知道更多关于我的特定 NVMe 驱动器的信息，我想知道它们与其他驱动器相比如何。我可以安全地擦除驱动器吗？我怎样才能检查它的完整性？
+
+这些问题让我在互联网上搜索，发现了一个开源项目，其中有一系列管理 NVMe 驱动器的工具。它被称为 [nvme-cli][3]。
+
+### 安装 nvme-cli
+
+你可以从你的发行版的包管理器中安装 `nvme-cli`。例如，在 Fedora、CentOS 或类似系统上：
+
+
+```
+`$ sudo dnf install nvme-cli`
+```
+
+在 Debian、Mint、Elementary 和类似系统上:
+
+
+```
+`$ sudo apt install nvme-cli`
+```
+
+### 探索 NVMe 驱动器
+
+在为我的发行版安装 `nvme-cli` 后，我想探索我的驱动器。`nvme-cli` 没有手册页，但你可以通过输入 `nvme help` 获得很多帮助：
+
+
+```
+$ nvme help
+nvme-1.14
+usage: nvme <command> [<device>] [<args>]
+
+The '<device>' may be either an NVMe character device (ex: /dev/nvme0) or an
+nvme block device (ex: /dev/nvme0n1).
+
+The following are all implemented sub-commands:
+list List all NVMe devices and namespaces on machine
+list-subsys List nvme subsystems
+id-ctrl Send NVMe Identify Controller
+id-ns Send NVMe Identify Namespace, display structure
+id-ns-granularity Send NVMe Identify Namespace Granularity List, display structure
+list-ns Send NVMe Identify List, display structure
+list-ctrl Send NVMe Identify Controller List, display structure
+nvm-id-ctrl Send NVMe Identify Controller NVM Command Set, display structure
+primary-ctrl-caps Send NVMe Identify Primary Controller Capabilities
+[...]
+```
+
+### 列出所有的 NVMe 驱动器
+
+`sudo nvme list` 命令列出你机器上所有的 NVMe 设备和命名空间。我用它在 `/dev/nvme0n1` 找到了一个 NVMe 驱动器。下面是输出结果：
+
+
+```
+$ sudo nvme list
+
+Node SN Model Namespace Usage Format FW Rev
+
+\--------------------- -------------------- ---------------------------------------- --------- -------------------------- ---------------- --------
+
+/dev/nvme0n1  S42GMY9M141281 SAMSUNG MZVLB256HAHQ-000L7 1
+
+214.68 GB / 256.06 GB 512 B + 0 B 0L2QEXD7
+```
+
+我有一个名为 `nvme0n1` 的驱动器。它列出了序列号、品牌、尺寸、固件版本等等。
+
+通过使用 `id-ctrl` 子命令，你可以得到更多关于该硬盘和它所支持的特性的信息：
+
+
+```
+$ sudo nvme id-ctrl /dev/nvme0n1
+NVME Identify Controller:
+vid : 0x144d
+ssvid : 0x144d
+sn : S42GMY9M141281
+mn : SAMSUNG MZVLB256HAHQ-000L7
+fr : 0L2QEXD7
+rab : 2
+ieee : 002538
+cmic : 0
+mdts : 9
+cntlid : 0x4
+ver : 0x10200
+rtd3r : 0x186a0
+rtd3e : 0x7a1200
+[...]
+```
+
+### 驱动器健康
+
+你可以通过 `smart-log` 子命令来了解硬盘的整体健康状况：
+
+
+```
+$ sudo nvme smart-log /dev/nvme0n1
+Smart Log for NVME device:nvme0n1 namespace-id:ffffffff
+critical_warning : 0
+temperature : 21 C
+available_spare : 100%
+available_spare_threshold : 10%
+percentage_used : 2%
+endurance group critical warning summary: 0
+data_units_read : 5,749,452
+data_units_written : 10,602,948
+host_read_commands : 77,809,121
+host_write_commands : 153,405,213
+controller_busy_time : 756
+power_cycles : 1,719
+power_on_hours : 1,311
+unsafe_shutdowns : 129
+media_errors : 0
+num_err_log_entries : 1,243
+Warning Temperature Time : 0
+Critical Composite Temperature Time : 0
+Temperature Sensor 1 : 21 C
+Temperature Sensor 2 : 22 C
+Thermal Management T1 Trans Count : 0
+Thermal Management T2 Trans Count : 0
+Thermal Management T1 Total Time : 0
+Thermal Management T2 Total Time : 0
+```
+
+这为你提供了硬盘的当前温度、到目前为止的使用时间、不安全的关机次数等等。
+
+### 格式化一个 NVMe 驱动器
+
+你可以用 `nvme-cli` 格式化一个 NVMe 驱动器，但要注意。这将删除驱动器上的所有数据！如果你的硬盘上有重要的数据，你必须在这样做之前将其备份，否则你**将会**丢失数据。子命令是 `format`：
+
+
+```
+`$ sudo nvme format /dev/nvme0nX`
+```
+
+(为了安全起见，我用 **X** 替换了驱动器的实际位置，以防止复制粘贴的错误。将 **X** 改为 **1** 或 `nvme list` 结果中列出的适当位置)。
+
+### 安全地擦除 NVMe 驱动器
+
+当你准备出售或处理你的 NVMe 电脑时，你可能想安全地擦除驱动器。这里的警告与格式化过程中的警告相同。首先要备份重要的数据，因为这个命令会删除这些数据！
+
+
+```
+`$ sudo nvme sanitize /dev/nvme0nX`
+```
+
+### 尝试 nvme-cli
+
+`nvme-cli` 命令是在 [GPLv2][4] 许可下发布的。它是一个强大的命令，有很多有用的选项，它是控制你如何管理数据的好方法。
