PCIE1 Raid Card

[kaaskop]

Anyone using an addin raid card? Ive tried a SATA I raid card and after some serious problems trying to get the driver working on Win7 with a fresh install i dont see much improvement in my harddrives performance while using a raid 0 setup.

Copy speed of the drives without raid is something like 40MB/s and with raid it starts on 90 and goes down to 40 anyway.

You will not be the first person to be disappointed with the perceived versus actual performance of RAID implementations. The benefits depend largely on the type of IO that is occuring.
