In case you need storage size in the future this looked like a nice price.
It goes on sale for 119.99 starting 4/14:

If I attach to a PC that doesn't have UASP support the speeds you show are about what I get for a ~US$100 item (256GB NVMe M.2 in a USB 3.1/Thunderbolt 3 NVMe enclosure). If I plug it into a PC with UASP capability, those speeds double. Curious to know if you can try that for yourself (you'll need a 2018 PC or laptop or newer, most likely).
HTH,

OK, just read up on UASP. My comp supports it.
Keep in mind though that those speeds are the max. the "device" itself supports.
Check if your USB 3.0 device supports USB Attached SCSI (UAS) Protocol
My chipset definitely supports it. I doubt the device does. Or if it does... it's already in use.As stated earlier, UAS Protocol will be used by Windows 8 and later only if your USB 2.0/3.0 mass storage device supports it and your USB chipset/firmware support it.
