The following is a handy dandy chart I stumbled on tonight that lists all the M.2 NVMe 2230 SSDs on the market along with their rated speed and IOP read and write performance.

Speaking of which, being a curious cat and a glutton for punishment, I just ordered a 2TB Western Digital SN740 from Taobao via Superbuy here. With any luck, I will be off and running and installing one in the next month or so in my very own Surface Pro 8.
