I've also got a SCSI2SD V6 in each of my two AlphaSever DS10 systems.  I had a few issues with the MV and an earlier version of the V5 firmware, but the last few versions have been no trouble at all.

This is definitely good info John, how is the SCSI2SD performance on the DS10’s?  I’m pondering using either an AlphaStation 200 4/233 or a AlphaStation 500/333 as a workstation, rather than my DEC PWS 433a or my Compaq XP1000/667, simply due to power usage, and heat generation.

I just placed an order for the initial 4 V5.2 boards I’ll need.  Once they have V6 boards back in stock, I’ll need to order a couple of those as well.  These should definitely help reduce heat, noise, and power consumption.
