Hello community,


this might be a special case question.


I'm running a Windows 7 NAS with Intel RST and Raid 5 on 4 disks.


It happens that I write a lot of data to the Raid, which is naturally very slow (20MB/s). To get more performance I choose Write-back as cache method in RST. For short writes this gives me the whole network speed (around 100MB/s), but on longer writing processes, sooner or later, it falls back to a very slow level.


Having a closer look to the NAS system, I recognized a portion of RAM which grows during file writes until it hit around 1GB. This is exactly the time the speed is dropping.


Since I have plenty of spare RAM, I ask if there is any way to increase the drive cache size in the RAM?










I hope for answers, thank you!
