I have a DC-10 as a third drive off my controller. It works great.  I have ESIX
Rev. D, and I bought the driver from CMS.  The UNIX compatibility list for the 
driver/software doesn't mention ESIX, but I figured that since it listed 
everything else, including XENIX, it would have to work.  It did.

If you have a DC-10 and you run UNIX, get the driver.  On my machine (a 25 MHz
486) it backs up about 80 Mb of info to one tape (compression on), and it only
takes about 25 minutes (or around 3.6 Mb/min).  Not bad for a tape drive hung
off the floppy controller.

Of course, if you don't have a DC-10, I wouldn't recommend getting one (for
UNIX anyways). Why?  DC-600 carts. are the standard for data-interchange
between most UNIX boxes based on Intel platforms as far as I have seen.

On the other hand, the new DC-20, the 250 Mb version of the DC-10 looks *real*
interesting. For a street price of around $500 (which includes the
almost-mandatory option of the controller), you get a very nice tape unit that
is quick, uses DC-2000 carts., and can put 120 Mb (physically) on the tape. 
The reason it is called a 250 Mb tape is because CMS figures that on average
you get 2.0:1 compression ...
