I think newer SATA controllers and drives (SATA II) support "native
command queue" (NCQ) requests, which make them comparable to SCSI for
server environments (e.g. the 3Ware 9000 series). NCQ allows a drive to
re-order commands and process them in proximate (data) order instead of
received order.
>From what I've heard, scsi is much better than sata for large databases as
it sorts the request for data in sector order before beginning retrieval,
resulting in better throughput in multi user environments. Sata is fast,
but doesn't sort the requests, so it's great for single user systems due to
Hi,
We are looking at IBM's new DS4200 storage device for use with our
unidata database but have been pushed away from SATA by an IBM sales
partner. I was wondering if anyone has tested using SATA drives for their
database or know of a reason not to. Thanks!
