Lets look at the numbers: IDE Disks: 800,000 hours MTBF SCSI Disks: 1,000,000 hours MTBF IDE Disks: 91.57 Years SCSI Disk: 114.46 Years Humm.... I don't think the machines will be usable that long in either case. For 6 disks the MTBF numbers are: 6 x IDE Disks: 15.26 Years 6 x SCSI Disk: 19.07 Years Still longer than any machines (worth using) still in use. The difference in cost will be about 2.5 (for SCSI) to 1 (for IDE). Its your money. The disk manufacturing techniques used today have come a long way and are being made about as reliable as they can get. The type of disk is no longer a factor. 3 to 5 years ago your comment had merit. Also take into account the SCSI disks use more power and run hotter than IDE disks. In the same chassis with equal cooling the MTBF will be almost identical. The difference in cost for the same amount of storage can no longer be justified.

IDE disks are much less reliable than SCSI. -- HTML mails are going to trash automagically -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: http://www.redhat.com/mailman/listinfo/fedora-list
