zfs discuss - Jan 2009 - Comparison between the S-TEC Zeus and the Intel X25-E ??

I''m looking at the newly-orderable (via Sun) STEC Zeus SSDs, and
they''re
outrageously priced.

http://www.stec-inc.com/product/zeusssd.php

I just looked at the Intel X25-E series, and they look comparable in 
performance.  At about 20% of the cost.

Can anyone enlighten me as to any possible difference between an STEC 
Zeus and an Intel X25-E ?  I mean, other than those associated with the 
fact that you can''t get the Intel one orderable through Sun right now.

The Intel part does about a fourth as many synchronous write IOPS at  
best.

I have been testing the 32 GB X25-E last week.

When I connect it to one of the onboard (tyan 2925) sata ports, it''s
not detected by opensolaris 2008.11.

When I connect it to an PCIE LSI 3081 , The disk is found But I''m
getting trouble when I run performance tests via filebench.

Filebench exports the zpool before every test to flush the cache, here is were
the test is sompletely frozen. via dmseg I see:
