The Beige is limited to 16.67 MB/sec, which is a LOT less than the internal transfer rate of the drive (about 40 MB/sec) or the practical external transfer rate (about 20-33 MB/sec). >The two meg cache drive seems to be plenty adequate for DV video too, by the >way. Yes, 2 MB is enough. I think is was WD which first popularized the 8 BM cache. But, that was needed because WD's caching algorithms were inferior to those in otherwse identical drives which had only 2 MB. Problem was, both drives were made by IBM, and IBM's caching algorithms were far, far better than WDs. (WD no longer is rebranding IBM drives as its own). -- G-List is sponsored by <http://lowendmac.com/> and...
