That roughly translates to 7-12 MBytes/sec, >sustained. Oh, if it were only that simple. That Mb/sec number is probably raw platter rate. Do you know what physical coding scheme they are using? How much header, gap, ECC, etc.? A typical number used to be 40% overhead, but may be much better now. I wouldn't expect 7-12MB/sec. OTOH, my old 12550N on an Alpha used to hold down 5-7MB/sec for quite some time. Cheers, David
