I noticed that the max. throughput on an internal hard drive is
8.0MB/sec for a 330MB drive and only 2.5MB for a 660MB drive.  I would
have expected that you could get a higher throughput on the 660MB
drive(shorter seek times).  Why isn't this so?  The SCSI is suppose to
transfer at 4.8MB/sec.  Can I get this kind of throughput on an external
hard disk?  It sounds like an internal 330MB drive is preferable to an
external one on a slab.

On a related note, will I notice the difference b/w a hard drive with
15ms and 10ms access time(on the NeXT)?
