Got the Lexar SL100 today. Overall, happy with it as (anecdotally) seems a bit faster than the T5 while doing some copying of data over.
Same size as T5. Comes with short cables, but OK as I have the longer Samsung cables that I can use.
Speed test not hitting the theoretical max. Was seeing speeds of about 650-680Mbs for both read and write. Again, OK with it as the most intensive thing I will be doing with it is running some VMs off of it, and those seemed to start up quicker than off the T5. BTW: the drive is formatted as APFS encrypted, which might be impacting speed.
For the price I paid, no complaints.
