View Full Version : SCSI hard drive vs S-ATA / ATA hard drive. Jamie 11-07-2005, 11:19 What's your opinion of the relative performace of a SCSI hard drive compared to either a S-ATA or a ATA hard drive? Vini 11-07-2005, 11:29 scsi generally a lot faster. sata is working its way upto scsi speeds, ata is just your good old ata. Joelc 11-07-2005, 11:49 SCSI is the fastest, but its also the most expensive, also it has the advantage of being hot swappable, and being able to take upto 7 devices per channel, IDE can have 2, SATA can have one. SATA is very good, and getting much faster then PATA drives. Joel steev 11-07-2005, 11:53 Fantastic timing, I've just been chacking out various speeds in Linux using hdparm. Results so far... My hda (IDE) - 45MB/s Older server (IDE) - 23MB/s My sda (SATA RAID) - 33MB/s HighPoint *ahem* "RocketRAID" 1542 with 2 x Seagate 120GB SATA SATA software RAID VIA chipset Seagate HDs - 53 MB/s £300 PCI-X 3ware SATA card & WD Raptors - 70 MB/s U2W PCI-X SCSI with Raptor equivalents (10,000RPM) - 65 MB/s (admittedly rather old Adaptec card) |
