[sdnet.computing] SEIMANS DRIVES

I am trying to design an S100 system.  It will consist of a
Intercontinental Micro Systems SBC 48000 board.  I also want 8"
drives.  It's been recommended that I use either Mitsubishi or Qume
drives, but I double drive system with case and supply is upwards of
$1500!.  I have considered using Seimans drives, as I can get a DSDD 2
drive system for $500.  I've heard these drives have a higher
breakdown rate, how much higher.  Is saving $1000 worth it or will I
be replacing the drives every year.  Also, any good recommendations on
terminals would be appreciated (<$600)

Workman & Assoc. has ten Siemens 8" SS drives in action.  We've had a
bad time with DOAs, but once we found drives that worked, they always
worked.  Don't know about the DS ones.

The Siemens drives are a little slower than yon Qumes.  We've had even
less trouble with Qumes.

With the price of Siemens drives, one of our peeps bought a spare drive.
Priority One's $99 price is only $25 more than official service price.

W&A also sells spare parts kits for the Siemens SS drives.  This
includes belts, index assemblies, etc..  We've had much less call for
them than the Tandon 5-1/4" drive kits (of which we have sold
hundreds).  Of course, Tandons have the famous door latch problem.

A warning on Mitsubishi 8" drives.  They ain't standard.  CompuPro, CCS,
and several other systems upchuck when you attempt to use them.  There
are differences in the precompensation settings & other things.  This is
why Priority One no longer sells them.
