this PM961 ran once in its original system...upgraded to a 960 Pro 1TB and this sat around for few months

tried throwing it in a 10 year-old Core 2 Duo system which is apparently do-able but I'm too lazy for the workaround

TweakTown's review of the 1TB variant gave it a near-perfect score 96%
Samsung PM961 1TB M.2 NVMe PCIe SSD Review

comes pre-installed with Genuine MS Windows 10 Pro 64-bit OS ($180+ value)

comes with adapter so you can drop it in a desktop's PCIe slot ($30 value)

this is a turn-key solution...priced to sell given the extras and skyrocketing NAND prices
