Correct.

It is true that a Flash based SSD, will be adversely impacted by 
ZFS not supporting TRIM, especially for the ZIL accelerator.

But a DRAM based SSD is immune to TRIM support status and 
thus unaffected.  Actually, TRIM support would only add 
unnecessary overhead to the DDRdrive X1's device driver.
