Anyone used the OWC (other world computing) SSD (6G) for RAID Array?

Yes I do have budget issues. I also visited SSd page on Tom's hardware
site
which was more than 8 months old.
I did not access the SSD market for a while. Yesterday one of our
colleagues
sent me a link at OWC which indicated that their drives has writing
speed above 500MB
for some of their 6G SSD drives. I thought SSD was at 150MB usually
therefore
this is very attractive to me for our app which pulls a high volume of
dataflow from
the central RAID.
one thing to watch out for with SSDs, most of them do not have good
behavior in the face of power failures. they all cache writes in ram on
the disk and most of them have no way of getting those writes to flash
if the power fails.
This, along with price and performance is one of the reasons that I like
the Intel 320 SSD. I get them on amazon. You can probably get faster
with OCZ, but the reviews on the reliability of the OCZ on amazon and
other places made me a bit nervous. This 320 is about as fast as our
older, smaller X-25E drives, but at significantly higher space for lower
price.
ALso, it has a capaciter to flush the SRAM to flash (small since it just
keeps mapping tables there). This makes it suitable to use as a ZFS ZIL,
among other things.

I did some extensive looking around for about 3 days and various tests
before settling on this one in the Summer time frame.
