I've always seen SCSI drives sized for an uneven capacity like 36.7, 73.4, or 146.8 GB, but SATA drives always have even capacities like 80, 120, or 250 GB. Why the disparity? Is there some technical aspect of the SCSI interface that makes those capacities easier to implement?
And why did they finally break the trend with 300 GB drives? I would have expected the next size up to be 293.6 GB.
Edit: clarifying that question is about SCSI vs. SATA
