The DRAM cache helps with lasting performance when the drive is choked with a lot of operations like compressing/decompressing data, installing games/updates etc. A drive without this would slow down in such operations when the SSD has a lot of random ops.WD's 'algorithm' makes it irrelevant.
While you say the word "algorithm" which is used by WD it's not what they invented. They use a technique called Host Memory Buffer (HMB). To save cost of adding a DRAM on your drive itself they like to use your system RAM for it.
That being said, the cost does not justify the means. SSDs with DRAM cache are very near the price of such DRAMless SSDs. Unless you want just for storage and not OS I wouldn't recommend a DRAMless SSD.
