Why good external SSDs are faster with Apple silicon

After several days testing the latest Express 1M2 enclosure from OWC, I have changed my recommendations for the best external SSDs. Previously I had chosen the relatively reliable Thunderbolt 3 up to 3 GB/s, even though few drives ever seemed capable of achieving that up to. If you’re still needing good performance with an Intel Mac, that makes sense.

But if you need best performance with an Apple silicon Mac, you’re far better off with a high-quality USB 40Gbps enclosure such as OWC’s Express 1M2, which should reliably return over 3 GB/s even through a compatible hub. I much prefer the word over to up to.

If you have an Apple Silicon Mac, and you’re looking for an external drive – this is some good advice to follow.
