Well I finally have a result of my own to post, mSATA drive from about 2014.

[PHolder]

Unbelievably (considering I have much more powerful/capable machines) this is my primary machine these days. It's a Gigabyte BRIX 4010U with 16G of RAM and a 480G mSATA SSD. It's been well and truly used by Windows (it goes into hibernation at least once a day.) I've NEVER found it slow, despite what these results might imply.

Looks like the drive might be a candidate for SpinRite L3?

Thanks for posting your results!

It may not be as tip top fast speed as the fastest SATA III results we're seeing, but several hundred MB/s is still super fast! And I believe I've heard it said that most of day-to-day Windows use is to do with random access speeds, for files around the 4KB sort of size. Sequential transfers of big files aren't a typical use case scenario

You wait until you see NVMe speeds! Using the Linux Disks utility, mine benchmarks at an average of 1500MB/s, with peaks at 1900MB/s
