I don't know how much of it to believe, since it is marketing material, but the Seagate white paper on their site claims that all the command-queueing stuff brings the performance very close to that of scsi. This last weekend I put together a box with a 3Ware SATA RAID controller and two of the Seagate drives. The controller is probably a bit of a bottleneck, but that sucker was still incredibly fast for the price (about $300 for the controller, $100 for for each of the two Seagate 160GB drives). At $2 per mirrored gigabyte, I'm not complaining. Charles > FUJISHIMA Satsuki wrote: >> Currently native SATA drives are still not so popular.
