Hi All,
I have a customer interested in high end workstation. She wants RAID 1
to protect her drives. She is also interested in Solid State Drives.
(And she knows the difference between RAID and Backup.)
What host controller would you guys recommend for a pair of Intel
SSDSC2BW480A401, 480 GB 2.5" Internal Solid State Drives in RAID 1?
Many thanks,

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?
