To be fair, the $200 1TB SSD linked above is just a standard 2.5" SSD where the Apple SSDs are M.2 with triple the I/O speeds. These Apple(s) can't be compared to the list of oranges above.

Granted, it's a heck lot more expensive at 1TB for $700. It seems the only reason for this drive to exist is actual transfer speed because in any other way seems worse than the T5.
If you're willing (to pay) and able (to plug it in) to use Thunderbolt 3, there are several commercial products that use an NVMe internally and boast up to 2500MB/sec.
It's also not a 2.5" drive since it's obviously smaller.
