Question about cache flushing
Posted: Mon Apr 15, 2013 12:42 am
Hi,
I'm new to the forum and just wanted to say thank you for the opportunity to try this very useful software
I am caching my 240GB SSD (read & write), with a 2048MB cache size, and a defer write with a latency of 35 seconds.
I chose 35 seconds because (as I understand it as a n00b) windows sends the TRIM command to SSD's every 30s and I want the SSD and the cache to catch it. This should reduce wear on the SSD by trimming some data in-cache.
But my question is about write cache flushing.....
When I shut down the computer normally, the cache is obviously flushed to disk. But what happens when another program, for example an installer that asks to restart the computer, shuts the computer down. Does the cache still get flushed?
Does the write cache flush to disk in ALL shut-down situations (except for a full system crash, obviously)?
Just curious
Cheers,
Jamix
