Not knowing these devices personally, I'll just say I find most of these sorts of SSD performance summaries completely useless.

Too often, specs or even shallow benchmarks report little more than some theoretical peak speed from system to SSD controller RAM buffers, without any real information about reads or writes that actually go all the way to the solid state storage cells. And even when they do go all the way, they fail to really highlight performance variance for different realistic workloads...

As a general rule: any SSD benchmark that gives you a result of over 1GB/s is not measuring what's actually most important for day to day interactive use. And anything that's within a factor of two of the SSD's marketing numbers is probably relevant only to copying a single file to or from another SSD.

Sustained write speed is usually important as these things heat up and often aren't cooled properly. Which is not hard to test.

> 6200 MB/s Read, 4300 MB/s Write

That's in bursts though, not sustained. Though, that's probably completely fine for the target users for these devices.
