Just to confirm, it wasn't really a 'recommendation' in the sense of it being better or worse than any other such enclosure. It just happened to be one that I've used somewhat extensively and found to work with OpenBSD, (and has a JMicron chipset). > So an average transfer speed of about 134 MB/s. > > Attaching via usb type-c port does not work whatsoever, even when attached > upon boot. > > Does that match what I should expect at best from such a setup with OpenBSD? The performance is about what I would expect using that combination of enclosure and SSD. Regarding the fact that it doesn't work when connected via usb c, have you tested any other usb c devices? This sounds more like an issue regarding OpenBSD support for your usb controller, (which may even be 'fixed' by tweaking BIOS settings), rather than anything to do with a specific usb device. Note that there is a newer BIOS available for your machine than the one shown in your dmesg.
