I've been lurking around the forums for some time now. Seeing this thread made me want to register, which is a good thing . I manage a medium size IT shop for a research lab. Reading your conversation, I cant help but wonder when did this convo take place? Davis is wrong on several accounts: 1) Seagate, Maxtor, Fujitsu all have native SATA drives (although I dont think the general public can get the Maxline III's yet) 2) SATA is not more expensive. The drives are comparable in price (to PATA), however in the IT world, it is flat out blowing away SCSI. I just purchased an Triton 16Bay hot-swap Raid 5 SATA. It holds 6TB and it costs about $15k less than any comparable solution out there AND Im getting 220MB/s sustained transfer. Granted this is an extreme comparison because a majority of the forum users are home users. 3) 1 device per controller??!! He must mean mobo designers are only including 1 or 2 SATA pinouts. Each controller can actually support 2,4,6,8,16 SATA devices (depending if its a CERC, adaptec, Promise, etc) 3) His statements about P4, gigabit lan, etc..its not even worth rebutting Bottom line, every mobo made in the last 6 months (that isnt some value line ) comes standard with SATA and most of the times Serial Raid 0/1. Try comparing the performance between ANY PATA Raid 0 setup with Serial Raid 0. On one of my test box's I had a pair of Fujitsu PATA 120GB, 8MB cache, 7200rpm Raid 0 vs Maxtor Maxline Plus II SATA, 8MB cache, 7200rpm. Sandra Sisoft: PATA = 68MB/s, SATA = 93MB/s Just my 2.5 cents worth.
