but the write cache make it possible to have greater speeds .. why turn it off ?
And unexpected restart, will destroy all the data, because of write cache enabled ? It doesnt exist any utility to handle this ?
Write caching is great when you use a hardware RAID controller with battery backup. Good controllers won't allow write caching without a battery or when the battery is weak.
Write caching isn't a good idea on a PC that isn't on a UPS, is overclocked or not 100% stable. An unexpected restart causes a data loss and a rebuild is required because there is no way to determine if all drives are clean. This happens only if a write operation was in progress at failure time.
make sure you have the latest intel matrix console .... v8.8 I believe...
In the prior version, the console itself caused most of the bsod which then caused constant rebuilds and verification.
V8.8 seems so much more stable without problems with hotswapping. I only got one BSOD from 8.8 and that was waking the computer from sleep, of which I now shut down and power up normally. Upon rebooting, the drives needed verification.
Leaving the cache on means that any data, especailly the OS using the swap files will not be written to the disk on sudden BSOD, which means that the disk is now dirty requiring either a verification or rebuild.
Sudden reboot on intel matrix raids always annoyingly rebuild or verify; just the way of life...
