新盘是未格式化的状态，SMART 看一下信息：

通电时间 0，电源循环次数 3，读 4.6MB，写入为 0.

功耗共有 5 档，最低待机功耗为 0.005W，最大功耗为 10W。

我没有 PCIe5.0 的平台，只能用 PCIe4.0 的 X570 平台测试。

将磁盘格式化为 ext4 格式，下面是使用 KDiskMark 的测试结果：

LBA Sizes 大小出厂默认是 512，改成 4096 再测一次，几乎没有区别。

差别很小，说明根本无需改。

Windows 下用 TxBench 进行 RAW 全盘写入测试，根据 csv 格式的 log，使用 pyplot 作图如下：
\n $\"image|690x345\"$

共计用时 20 分钟 11 秒。
\n在 1 分 53 秒处，曲线呈断崖下降，提示此时模拟的 SLC Cache 用尽，此时共写入了 799175081984/1024**3=744.289794921875GB 的数据。

全程写入速率：
\n平均：3222.55 MB/s
\n最大：6728.33 MB/s
\n最小：1909.07 MB/s
\n标准差 (std dev) 1156.98 MB/s

如果只看中间这部分：
\n平均：2852.64 MB/s
\n最大：3432.20 MB/s
\n最小：1909.07 MB/s
\n标准差：254.04 MB/s

由于接的是 PCIe4.0 接口，本测试前段只能达到 PCIe4.0x4 的极限：7GB/s，PCIe5.0 平台上应该为 14GB/s。但中间部分速率仍有一定参考价值。

$\"Annotation$

期间使用 SMART 监控工具查看硬盘温度，起始温度 33°C，持续写入中温度为 78°C 左右波动，考虑到没有散热措施（金属马甲/风扇），这一表现符合 SM2508 主控 SSD 的一贯良好预期。
