M1 MB Pro and external NVMe speeds.

Good afternoon everyone. I bought and external NVMe and enclosure and I am not getting the speeds I thought I would. Does this sound right with what I am using?

Looks about right to me. As a matter of fact, that looks really good for a cheap USB-C enclosure. The enclosure specs point out that it is a 10 gbps USB-C port. So the absolute theoretical max for data transfer would be around 1000 MB/s. You're getting 75-80% of that absolute max which sounds right to me. I have an external San Disk SSD USB-C drive which gets around 650 MB/s. So count yourself lucky. What filesystem are you using on this drive? That might make a difference. What were you expecting?

Yeah, to go much faster you need proper thunderbolt enclosure.

I have heard that the Apple implementation does not tend to max out the bus on SSD's for USB, so this is probably about as good as can expect from USB.

Perfect, thanks. That is what I was kinda thinking but was hoping for a second opinion.
