I have a SANS DIGITAL TowerRAID TR8M-BP (with the RocketRaid 622 raid device) with 5 x SAMSUNG Spinpoint F4 HD204UI 2TB 5400 RPM SATA 3.0Gb/s harddrives in a RAID 5. It connects via 2-esata cables. My drivers are up to date.
When I'm writing data to the drives my computer stutters (meaning freezes for a 1/2 second every 2 seconds or so). My screen freezes, my music goes into a loop, its really annoying.
I get the same thing in windows 7 as I do in Linux. The only difference is it seems to happen less in Linux, but occassionally Linux will crash (I've never had Linux crash for any other reason, so I'm assuming they have poor Linux drivers and kernal mod).
Any tips for how to deal with this?
