Ultra reflects the fact that data is transferred on both the positive and negative transition of the signal, resulting in a signal's data carrying capacity being doubled for a given frequency. It's just a mechanism used to increase the data transfer rate. An Ultra ATA 66 or 100 drive should work fine, as the faster drives are backward compatible, though a 100 drive will only run at 66 speeds in your iMac (the number just refers to the maximum burst transfer rate in MB/sec, the actual substained transfer rates are much lower anyway).I believe the drive supplied in the iMac rotates at 5400 RPM. I guess you could replace it with a 7200 RPM drive, though this may generate more heat. Other than that, a standard 3.5 inch drive should be fine.[ 11-07-2002: Message edited by: RodUK ]</p> Sign In or Register to comment.
