[archive] SSD overview - zhihao - 11-29-2021 11:30 AM

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.

There is already an overview for ssds -- http://rar.shufangkeji.com:60380/showthread.php?tid=9219
i am merging info there and archiving this one. Make sure to FAIRR before creating a new item.
