ADATA ASU650SS-2TT-R Ultimate SU650 2TB 2.5" SATA 3.0 Solid State Drive

It is a pretty decent SSD but it does not come with a DRAM cache from what I know, nor is there any HMB on it. I think you'll still get pretty good speeds and any upgrades from a regular HDD to an SSD is a big upgrade, but it won't be blazing fast because of not having that DRAM cache and HMB. Please make sure to wait until the price drops though because right now this is absolutely overpriced for what you get.
