Can you tell me more about this? Are you unable to hit line rates, or are you just commenting about lackluster io options? I'm looking to add some M.2 storage via thunderbolt enclosure to my machine and would otherwise be expecting to be able to saturate the pcie lanes.
- exabrial 4y agoThis regression I've personally tested and confirm: You can't hit anywhere near "line rate" with usb 3.1/3.2, though an Intel Mac will gladly do so with the same _exact_ drive. You will experience write stalls and other performance problems. I don't have a usb4 drive to test by I wouldn't hold your breath. I do not have a Thunderbolt 3 device to test. Google tells me it's a problem: https://9to5mac.com/2022/04/18/m1-mac-thunderbolt-4-ports-speed-tests/ https://9to5mac.com/2022/04/18/m1-mac-thunderbolt-4-ports-sp... Expect _at most_half the advertised speeds and feel lucky if you achieve them. EDIT: From the article I linked: I just noticed they suggest try connecting my drive to a Thunderbolt 3 dock first. LOL, ok, I'll give this a try.
