Q&A told me about something on Maxtor drives that quiets that down, but at the cost of performance. he said if you disable it the drive performs better. I looked on the Maxtor site, but could not find a referance to it. Please help if you know what I am talking about. I am trying to figure out why my Raid array is not benching what Samdra says it should be, it is about 1/3 what sandra say a raid 0 array with 7200RPM hard drives should be. I did recently find out I must have got my cables screwed up and was using a ATA33 or something, since I noticed my Primary Master was only in UDMA2 mode while my Secondary master was in UDMA5. I changed cables changed both to UDMA5, and rebenched, getting the same mark as before the cable switch, what else can I do to get my array up to what it should be. What should I set the Cluster/Stripe size to in the Raid BIOS? It defaults to 64k, so thats what it is at now, should I lower it?
