Nothing unique to them.  I have a 4 year old SSD from a now out-of-
business company, Imperial Technology.  Initially we bought it for
about $20k with 1GB of RAM.  Subsequently upgraded to 5GB for another
$20k.  The speed is wicked fast even with just ultra2 SCSI (4
channels).  The unit has the same battery backup to disk stuff
(although it only does the backup at power fail).

At one time they quoted me about $80k to upgrade it to a full 32MB
that the unit supports.  I passed.

For my use it was worth the price.  However, given the speed increase
of other components since then, I don't think I'd buy one today.
Parallelism (if you can do it like Luke suggested) is the way to go.

And no, I have not run a database on one of these... though I am
tempted to...
