Does the 3D NAND 2.5" Blue Drives Have DRAM Cache?

I called customer support for Western Digital. To my amazement, they were unable to tell me if the WD Blue 3D NAND 2.5" SSD drives have DRAM cache. Some others such as the Crucial MX series at this price point have DRAM cache. I was hoping this line of Western Digital drives have it. Does anyone know? The specification sheet that is published on the website gives no indication one way or the other. Thanks.

Maybe check out online reviews ?

I’m not up to speed on SSD’s but …

This review says it has 512MB of LPDDR3 cache

I have read this review. The 512MB of cache was mentioned in the description of the previous model of the drive, not the current model being reviewed. Later in the review of the current model, it mentions that there “is a Micron made cache module” but no other details are given. It does talk about internal cache so I am assuming this drive does have it.
