I don't think that is true. They may not cache host data in DRAM, but I think that they keep some metadata in DRAM. That is similar to how the Intel 320 SSDs work -- they also do not cache host data, but they do have a small DRAM for holding metadata.

By the way, remember that some of the higher end Sandforce SSDs have/had a supercapacitor for backup power. There would be little reason for a supercapacitor if there was no information stored in volatile memory.
