scsi rll trade off questions?

[Kevin L. Allred]

I'm putting together a low end workstation for my personal use at home.
It will have a 386SX, 4MB memory and monochrome VGA graphics.
Initially I plan to just run MSDOS, but soon I would like to run UNIX.
I currently am considering hard drives in the range of 65 to 80 MB.  I
was only considering an RLL drive with 1:1 interleve controller until
I had pointed out to me that Segate has recently started marketing a
low cost SCSI addaptor (ST01 and ST02) suitable for use with its
ST296N 80MB hard disk.  This combination reportedly offeres about 750
KB/sec transfer rate, which is comparable to the 1:1 interleve RLL
transfer rate, and it is more cost effective.  Apparently the SCSI
addaptor works fine under DOS, but I have already had related to me
that it probably won't work with UNIX because of lack of drivers (I
heard that was a problem common to most SCSI boards even the expensive
intelligent ones like the WD7000).  Are the various UNIX vendors
developing drivers, so that I don't need to worry about this, or
should I stick with the RLL controller and disks?
