Write-Cache Buffer Flushing

post #1 of 7
Thread Starter

what are the consequences
SEAN please help
post #2 of 7
If caching is on and the computer looses power (or is shut off) before the cache is cleared, all data in he cache is lost.

If it's off, writes take longer.

Leave it on.

Write cache buffer flushing is not necessary on SSDs because they have large enough capacitors to stay on for few mili seconds and are fast enough to write whatever is in the cache before the loss of data from it.

You're thinking about something different. This is about flushing writes cached on the system's RAM, not writes cached on the SSD's internal RAM.
