Hi, I have been using the 3ware cards in RAID0 with great results. However, I just got a 5200 to use in a RAID 1 application. I was expecting a little less performance, but I was quite suprised to find that writing speeds were brutal. For example, to newfs a 2 drive array (2 quantum 13gig drives), it took 35 min. In RAID0, it flys as expected, and the array is quite speedy. Is writing speed really this bad (half of the speed of the same IDE drive by iteself) ? Or is it pilot error ? Bad hardware ? ---Mike ------------------------------------------------------------------------ Mike Tancsa, tel +1 519 651 3400 Sentex Communications mike@sentex.net Cambridge, Ontario Canada www.sentex.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
