This is the Acer Predator GM 7000 2TB gen 4 ssd with dram and boy is it fast. I include a free heatsink because this drive can get toasty during large file transfers.

The drive is still at 100% SMART data according to Crystal Disk Info. It has a 5 year warranty and is made by Biwin. The same company that makes the Biwin Black Opal SSD. They are a high quality manufacturer who buys NAND Flash and DRAM platters from different manufacturers and cuts them themselves. They have almost as much control over the manufaxturing process as Samsung, Micron, and SK Hynix whose ssd's are mostly vertically integrated which means they make all the components that go into an ssd.
