[comp.sys.next] Hard Drives for the Next

rocks@nmsu.edu (Dave Rocks) (10/09/90)

	While perusing the 'disktab' on my next I found entries for 2 200mb
	hard drives; a Maxtor LXT-200S and a Conner CP3200. It would seem
	that such a drive would provide a more adequate base for a Next
	"slab". The price for a Conner drive is $1129(IDS) and I don't think
	the Maxtor would be far from that. Why isn't one of those drives
	available from Next. In any case they seem a cheaper upgrade to a
	usable machine than going all the way to 340mb. Does anyone have any
	reason these drives would not work in the Next? Would their be
	performance problems? Noise? Reliability?

The key word here is *in*.  These drives may not fit in the slab.  If
they do indeed fit, then the disktab entries will(should) work with
the slab.  However, you can find the 340 MB drives from third-party
vendors at prices close to $1,100.00 I believe and 700 MB drives 
priced near $2,100.00 now.

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)?
