Nobody has yet mentioned the downside of Flash memory, so I'll mention it now. Flash memory, including Compact Flash, has limited rewrite cycles. This can be as low as 100,000, or as high as several million depending on the quality of the card. Once any given sector has exceeded its maximum number of rewrite cycles, it is in danger of becoming corrupt.
Some expensive CF cards keep track of how many rewrite cycles each sector has had. If a sector exceeds this amount, the data is moved to a different sector, and the sector which exceeded the rewrite cycle limit is marked as bad.
For this reason, Flash Memory is not really suitable as a hard drive replacement if you intend to make lots of changes to the contents of the disk. AmigaOS is better suited to a Flash drive as the OS itself doesn't need to write to the disk (unlike Windows, which seems to write constantly :roll:)
