Windows 7 - Write-Caching - Enable or Disable

Hello,

I noticed today when I ran an Intel SSD Toolbox scan on my RAID configuration, a section mentioning that I should enable Intel RST Write Back Cache. I could not find anything on my system about that so I came here and found your post about enabling write back cache. I followed the instructions and see that my SSD RAID setup shows as already checked off. I wasn't able to find the second screenshot you have there (within my own system) as you show for the Samsung drive. I don't know if this write back section is the same as the one Intel is referring to. Is the Intel RST feature something in the BIOS somewhere that I need to enable? because it currently does not see it enabled. Is it something that should be enabled? I went into the BIOS and took a look around but could not find anything. The Intel SSD 'help' section for this was not very helpful. Thanks

Hello Jeff,

Intel RST would be for your Intel Rapid Storage Technology RAID/AHCI/SATA drivers. If you have not already, you can download and install the latest 11.0.0.1032 WHQL version at the link below. Afterwards, see what options you have for the write back cache.

I assume if you DID check the 2nd write cache option, you could feasibly write a 16 mb file to the disk. The disk signals "data received" back to Windows even though said data is ONLY in the disk controller cache. You then shutdown the computer immediately after writing this 16 mb file. I would think windows would, during shutdown, issue the disk command to tell the drive to flush its controller cache AND WAIT for a reply from the disk that it has destaged all data.

It is working now. The original Intel program was on the MOBO driver disc but had not been loaded. Thank you for the link and your assistance.

That's great news Jeff. You're most welcome.
