[archive] SSD overview

[zhihao]

refer to http://rar.shufangkeji.com:60380/showthr...5#pid44495

-------

This board is for SSD related parts

Modern SSDs may have volatile and non-volatile cache, and this is perhaps related to PLP (power loss protection) which should be present on "enterprise" SSDs. The volatile cache is perhaps vulnerable to power loss, but the non-volatile cache should survive power loss, at least in theory. We may use hd-/sdparm/smartctl command to switch such caches on or off.
