Some people believe Mac has bad I/O. They kinda forget Apple even before Steve Jobs came back fixed that. It was only cheap models from 1994-1997 really that had I/O issues.

Early FireWire and USB drives also got their limits pushed on Mac but that wasn't Apple's fault.

Apple co-developed Thunderbolt and USB-C, which led to USB4 merging both.

As long as the enclosure uses the ASM2464PD chipset and you get the firmware on it up to date, different USB4 enclosures would perform identically...except for cooling which would be more on the design of the enclosure and presence or lack of fan.

Here's a good blog describing the chipsets
https://dancharblog.wordpress.com...sets-2022/

Here's a link to the ASM2464PD firmware - if you already have any enclosure with this chipset, you can update and fix disconnect issues if you're having them.

Here's a link to an enclosure with the same ASM2464PD chipset for half the price - 40Gbps

I got this when it was on sale last time for $85. Absolutely beast of an enclosure. Been going strong as my main drive for my Mac mini for almost 6 months with no hiccups. I'm tempted to get another for my 4K blu-ray rips.

Just curious why running on a mobo in linux its fine?
Thunderbolt chipset matching is tricky. A client device can work fine with one chipset and not another.

LaCie and OWC (two operations that have been around since before FireWire) now recommend JHL9480 client SSD enclosures. I tend to agree. ASMedia could have done a lot better.

Apple co-developed Thunderbolt with Intel, and then made their own host chipset. There is no way Apple didn't comply with the spec. Intel TB5/USB4v2 Thunderbolt client chipsets "just work" across Intel, AMD, and Apple hosts on TB3, TB4, and TB5.
