I'm new to RAID so please forgive any omissions.
I just setup a new RAID 5 with 4x 2TB drives on a PCI RAID card in Win7 64. I set them up in the BIOS and formatted a GPT partition with no issues. When I started to transfer my data from my old 1TB green drives it would start at ~40 MB/s for the 1st 500mb or so then quickly drop to about 2 MB/s. Since I ordered two of the RAID cards I swapped them out and the 2nd one wasn't much better. It would start at ~95 and drop to 4. Changing nothing I then transfered some files between two of the 1tb drives connected to the mobo at a steady 70 MB/s.
Is this just an issue of junk RAID cards? Do I need to go to PCI-Express for decent speeds? Any help would be appreciated.
Thanks
