I used a western automation ram disk for a short while (someone
locally was beta-testing it, I think) and found it to be slower than
my Wren V drive, which in synchronous and has a cache.

I think it didn't have a very good SCSI controller. I think I found
that it did better on very longer transfers, where it could amortize
the scsi overhead, but it never really did all that much better than
my Wren that I was impressed with it -- I would rather have had the
32Mb in my system cabinet.

Of course, they may have fixed this, and/or I may have mis-installed
it (although it did come up in synch scsi) or something.

For the money, I think buying one og the lightening drives would make
more sense, or putting the ram in the cabinet.
