The 10k RPM SCSI drives generally have slightly higher bandwidth and alot lower seek time than 7200 RPM IDE drives. I usually use the Maxtor Atlas 10k IV and more recently Maxtor Atlas 10K V drives as I think they are very solid performers. 15k RPM drives are usually not worth the premium as they don't have much higher bandwidth just lower seek times. For a slightly lower price tag I can recommend the Western Digital Raptor drive. It is a 10k RPM SATA drive that performs just as well as a 10k RPM SCSI drive, at least for streaming (high bandwidth) applications. But the best solution would be for you to buy some more memory and create a ramdisk and do your calculations there. Since you only need 0.5 GB that would be the best solution in my opinion. After you are done with your simulation you can copy the resulting file to disk just once. On Friday 26 November 2004 15:46, dave wrote:
I was running a 5200K RPM IDE drive and now am running Adaptec 29160 PCI SCSI card with 10,000K RPM SCSI drive.
Yes I do see a difference in speed :)

Hi- Does anyone have any experience if a scsi dirve on a PCI card is faster than IDE with 9.2 SUSE? If so how much faster and what PCI cards and scsi drives are you using? I am reading and writing a 0.5 gb geological model multiple times and seem to be IO bound Thanx Robert (Bob) L.
