IntelSSD 660P 512G M.2 2280 (SSDPEKNW512G8X1)

It's a cheap SSD, and it seems you get what you pay for. Testing its sequential write performance, it flies along for small-ish writes (10s of GBs) but if you go much larger performance tanks to about 60MBps.So probably fine for your average user or operating system but if you have specialist use cases I would suggest paying a a bit more for something better.
