Several drives support NCQ including the Maxtor Maxline III drives. > > Essentially SATA is a move towards SCSI technology, but hopefully without > the cost.

Obviously, that > comes at a cost. Oh it's a really big cost. An 80GB PATA drive is only $4 dollars less than an 80GB Sata. That's a cost difference under 5%. PATA is on it's way out the door so you are more likely to be able to use SATA drives in future machines than PATA drives (without add in cards or PATA to SATA Adaptors). The biggest thing keeping PATA connectors on Motherboards right now is that SATA optical drives are just now coming to market. As of Mid April of this year Intel had planned to release a motherboard without PATA connectors as early as the second quarter of 2005. SATA 2 will also change things with the ability to chain drives and the support of a 300MBps bus. On the server/raid side is where SATA is making the biggest splash. Currently the 3Ware's Escalade 9500s series raid cards are the fastest in their class, beating the other SCSI, SATA, PATA Raid cards in RAID 5 performance. These are SATA RAID cards and as such offer much cheaper RAID solutions than available using SCSI drives. Also it's become popular to use SATA to U320 SCSI or SATA to Fiber Channel disk attached storage devices. These RAID arrays can be hooked into SAN or to your database server at a fraction of the cost for a similarly sized SCSI or Fiber Channel Arrays. -- Mark Lane, CET -- mailto:[EMAIL PROTECTED] Sales Manager -- Hard Data Ltd -- http://www.harddata.com T: 01-780-456-9771 -- F: 01-780-456-9772 11060 - 166 Avenue Edmonton, AB, Canada, T5X 1Y3 --> Ask me about our New Dual and 4 Way Blade Servers <-- _______________________________________________ clug-talk mailing list [EMAIL PROTECTED] http://clug.ca/mailman/listinfo/clug-talk_clug.ca
