I was thinking about STEC ZeusRAM, but unfortunately it's SAS only
device, and it won't make into X4540 (SATA ports only), so another
option could be STEC MACH16iops (50GB SLC SATA SSD).
Perhaps you should also consider ddrdrive
I work a lot on flash...  and I've got to say...  dram is a lot faster.
Mostly because of design/implementation limitations in the present
controller technologies.  Restrictions about which blocks can be erased
when, and how many erase in parallel, under which circumstances etc etc
blah.  That's mostly where any delay comes from.  Straight out of the box,
SSD's perform very well.  But in real life, only moderately well.

Yes, I was thinking about that, but X4540 "Thor"s have only low profile PCIe slots, and DDRdrive X1 requires full heigh slot, unfortunately.
