A8N-SLI slow transfers to raid5 PCI card Tags: Asus SATA Motherboards Last response: February 7, 2006 4:07 PM in Motherboards Share deaddawg February 7, 2006 5:38:43 AM Hello. I just finished building a file server. A8N-SLI 3700+ 1GB Ram 2 x 160GB WD1600JB 8MBPATA 2 x 200GB Maxtor DM 8MB SATA Hightech RocketRaid 1640 PCI 4 x 300GB Maxtor DM10 16MB Raid 5 When I copy from a PATA drive to my Raid5 array, the copy goes very fast. When I copy from a SATA drive to a PATA drive, the copy goes very fast. Oddly enough, when I copy from an SATA drive to the Raid5 array, it goes about 1/4 the speed then the copy from a PATA does. The two 200GB SATA drives are plugged into the nforce4 SATA controller, not the Silicon controller. And the reason I am not using the silicon sata raid controller is because the raid5 array with be moving into a different machine.

EDIT: just realized you are in fact using a RAID card. Here's the thing: PCI sucks. The maximum theoretical bandwidth is 133MB/s at 33mhz. Can you say bottleneck? Trying to move files from your PATA or SATA drives to and from your RAID5 array is like trying to push an oyster into a slot machine. Or something... It just doesn't work. To increase performance purchase a PCI-e RAID controller or move the array to the NVRAID SATA ports. -mpjesse Can't find your answer ? Ask !
