I bought a brand new SanDisk Ultra® II mSATA SSD for my PCI-e mSATA adapter. Did it to get more space for games. A 256GB Wave chip was replaced with a 512GB chip.

I did a benchmark with AS SSD Benchmark tool version 1.9. Here is the result:

Running Windows 10 1607
Running Windows 10 1607

Note that this score is less than the Wave 256GB chip that was really cheap.
