Whether you will notice either of the above in practice is debatable - USB-C provides enough bandwidth, even with the rather slow USB performance on Apple Silicon, to do just about anything you'd want to do with a sample drive.

There are a couple considerations when deciding between USB-C enclosures and Thunderbolt:ġ) Thunderbolt will provide better performance with just about any current NVMe drive, since even USB 3.2 Gen 2 won't give enough bandwidth for even a relatively slow driveĢ) USB-C drives perform a bit worse on Apple Silicon Macs than on Intel Macs, which will accentuate the performance difference vs Thunderbolt You should generally be able to get drives for <$100US/TB. I've had good luck keeping an eye out for good prices on Crucial or Intel NVMe drives for external use - most recent drives are more than capable of hitting the Thunderbolt 3 & 4 data cap (~2.8GBps). The difference in NVMe prices is largely down to name brand - Samsung is a big name in the space, and commands a premium, as do some extreme performance lines from other brands (you shouldn't bother with those for external use, regardless).
