Hello out there.  I'm trying to decide which path to take in expanding our
disk storage capacity.  Right now we have 3 RF71's on a uVAX 3800 which
haven't given us any trouble at all (in 2 years).  But we need more space.

Anyone have any experience or opinions on using a 3rd party configuration?
The one I am considering would include a Toshiba Polaris series 1.2GB SCSI drive
in combination with a CMD Technology CDI-4000 SCSI to DSSI adapter, mounted
in a single (611) or dual (520) desktop enclosure cabinet.
The sales literature claims that this configuration is about 38% faster than
an RF71 and slightly faster than an RF72 (with larger capacity).  I noticed
that the Toshiba drive uses RLL encoding, which concerns me a little.
I seem to remember from my PC days that the RLL drives tended to crash a
bit more often.  Of course, that was with MSDOS (messy-dos).  But, I still
feel a little leary about RLL.  Anyone know what encoding method the RF71
and RF72 use?

Thanks for the help........ john
