Massive Store in a Small Drive
I've had this drive installed for about three weeks now and have nothing negative to say about it. It's fast and has tons of storage. Exactly what you'd expect of a small factor SSD.

The baddest ssd for handheld gaming devices.
OMG. This is the fastest m.2 2230 ssd ever. Slap this bad boy in my Lenovo Legion Go and it transformed it into a beast. The read/write speed exceeds expectations. A must buy. Just a little expensive but it’s definitely worth it. Outperforms all m.2 2230 on the market. First picture is the Speedtest of the ssd inside the Legion go and the Second picture is the Speedtest of the WD black SN 770M
