Hi All,

This from LSI tech support:

       The deal breaker is TRIM.

       Once you put drives into the array, TRIM is not
       supported.  So you will have to sacrifice TRIM
       for RAID and or visa versa.

       You can use an HBA such as 9207-4i and set up
       software RAID 1 and use TRIM, but there is no
       controller cache.

       Or

       You can use  9261-4i 9266-4i or 9271-4i with RAID, 1 gig
       of controller cache but no TRIM.


So ... poop!

Wonder if there are any enterprise level SSD's that don't
need TRIM?
