DX4000 SSC cache?

WD Legacy Products Sentinel Products

Hi, we own few DX4000 sentinels, mainly because of the Windows OS DFSR use in small subsidiaries.
Replacing 2GB with 4GB memory module already boosted the device performance.

Since the device is using Intel RST i was wondering if any of you tried to add a ssd (if you have a free slot) and enable SSD cache in Intel RST?

regards,
