TB3 is more popular then USB 3.2 2x2 which is impossible to find in notebook and very rare in Desktops.
Can you please gather the best NVME external boxes in the market and test them with something like Samsung 970 Evo Plus or 970 pro ? make a round up ? and see if they reach 3000MB/s ???
I review all kinds of SSDs, including TB3 and USB of all types. I'll look into it. Is there anything specific you are looking for?
Because all portable SSD are a box with internal off the shelves NVME SSD .. I am 100% sure you will find the same Version of SANDISK Extreme Pro as a stand alone NVME ...
Also you need to tear down the External drives in each review to see which NVME SSD is in there ... it will also help you to determine TBW/IOPS if the external drive does not say just by discovering which NVME SSD they are using inside.
Yes, most are just M.2s in an enclosure. It's hard to or impossible to open some of these without destroying them, which I try best to avoid. This drive is powered by a WD SN730E, as mentioned in the review, so I already know the specs inside and out. The WD Black P50 uses the SN750E. The cheaper WD My Passport SSD and SanDisk Extreme have WD's Blue SN550E inside them, too. You can read my reviews on those to learn more if you like.

I have rarely seen a company include that metric for a portable SSD. Typically, they are just warrantied by time alone. Also, most endurance ratings are conservative, but yes, you can get an estimate of expected endurance by understanding which SSD is powering the device. It's just that TBW warranty coverage restrictions do not apply to most portables.
As for IOPS - what is the point of testing the device outside of its designed enclosure if it is forever going to be used in the enclosure? I can test portable SSDs' IOPS perfectly fine as they come. They are not going to be used as internal SSDs, only as portables. So, comparing the performance without the bridge chip they come with is irrelevant. And again, I've already reviewed the internal devices as linked above.
