behavior and consequence of a failing/failed SSD

[kchung]

What will happen to the system if we have a bad SSD?

• Cached read enabled
• SSD fails to read
• SSD fails to write
  
  Cached read/write enabled
• SSD fails to read
• SSD fails to write

First, a cache hit rate of 100% is impossible. Writes cached or not makes no difference. There will always be reads and writes that bypass the cache and go directly to the SSD. Windows will show its standard behaviour: either throw an error message or more likely: BSOD.

Apart from that, the disk controller will signal the failing disk to Windows so you'll end up with the same error or BSOD.

In all cases Windows will crash and your data is lost.

It sounds like kchung is asking how PrimoCache will react to its L2 SSD failing. It could trigger a disk error (which may then trigger a Windows crash) or it could disable L2 caching and pass reads/writes through to the underlying disk, which may still be OK. I think only Support can answer that.
