Performance

Not sure if this belongs here or on SuperUser, feel free to move as appropriate.

I've noticed the performance on my RAID0 setup seems to have degraded over the past months. The throughput is fine, but I think the random access time has increased or something.

In use I generally see about 1-5mb/sec when loading stuff in Visual Studio and other apps and it doesn't seem like the CPU is bottlenecking as the CPU utilization is pretty low. I don't recall what Access Time used to be, but HD Tune is reporting 12.6ms Read throughput is showing as averaging about 125MB/sec so it should be great for sequential reads. Defrag daily and it shows fragmentation levels low, so that shouldn't be an issue.

Additional info, Windows 7 x64, Intel raid controller on mobo, WD Black 500GB (I think 32mb cache) x2.

If you have 2 raptor 10k rpm drives in Raid0, can you add another sata (7200prm) drive outside of the RAID or would it have to be inside the RAID? What would be the consequences of adding a 7200 RPM drive to the raptor 10k rpm RAID0 besides the I/O speed going to 7200rpm. >>> More
