Pros: I measured the write speed of very large files on the fastest computer available from Apple. M3 Max, with no other work happening to speak of, and plenty of extra CPU available. MB written to /dev/disk4: 54.7MB/s MB written to /dev/disk4: 30.7MB/s MB written to /dev/disk4: 29.7MB/s MB written to /dev/disk4: 20.9MB/s MB written to /dev/disk4: 41.9MB/s MB written to /dev/disk4: 48.1MB/s MB written to /dev/disk4: 48MB/s MB written to /dev/disk4: 32.3MB/s MB written to /dev/disk4: 18.8MB/s MB written to /dev/disk4: 53.5MB/s MB written to /dev/disk4: 16.1MB/s MB written to /dev/disk4: 52.3MB/s MB written to /dev/disk4: 46.2MB/s MB written to /dev/disk4: 29.5MB/s MB written to /dev/disk4: 26.5MB/s MB written to /dev/disk4: 43.5MB/s MB written to /dev/disk4: 38.2MB/s These are over 10 second intervals. You'll notice this card never exceeds 60MB/s and an inconsistent but in the range between 16-55MB. It's quite cold in here now, but I did not notice it seems to heat throttle itself or something in warmer conditions, when that happens (usually about 45 seconds in) speeds will drop from ~60MB/s to never more than 30MB/s.

Cons: I don't know what they were smoking when they claimed it could write data at 160MB/s, it does not even write at 60MB/s.

Overall Review: I wasn't expecting great performance and it works and fits flush to the MacBook Pro w/ this adapter BASEQI UHS-II Aluminum microSD Adapter for 2021 M1 MacBook Pro 14 & 16 (Adapter, Silver), so I'm happy I saved the money not paying Apple for more storage as performance is not critical. I've bought 6 256GB Pro+ MicroSDXC cards from Teamgroup recently, one of them has become completely unrecognized by any operating system and thus all data is lost. They all also have a tendency to completely hang during use requiring force-quit of any application using them, but none the ones that hang have actually lost any data after a reboot. This device has NOT had either thus far and given the price I would recommend it for anyone who wants the highest capacity micro-SDXC possible without paying an arm and a leg.

Pros: It works. It is a one Gigabit ethernet adaptor as is standard nowadays, I was hoping for the 10Gbps which it says also, but at this price I don't think a 10Gbit adaptor is even possible.

Cons: Description is misleading, card cannot do 10Gbps networking.

Overall Review: If you want 1Gbit networking - say for a system which only has wireless (like any MacBook Pro nowadays) it works just fine for that.

Pros: It has Thunderbolt ports than can be used for graphics (in theory) though this barely works.

Cons: I wasted money buying 4-sticks of expensive overclocking Corsair RAM and the system can't remain stable even at basic speeds well below that advertised. With 2 sticks of memory only present, it is usable but unreliable - it will sometimes hang/bluescreen crashes and most of the time will fail to resume from power save mode, requiring a full power yank. I don't use the computer for any real work, so its the not the end of the world if it crashes on me, but often it corrupts the windows boot sectors so I constantly have to re-install windows.

Overall Review: I don't recommend. But I'm too lazy to RMA it and deal with installing it again.

Pros: AMD sent me a system with this case for software development. This is one of the sweetest cases I've seen. Lots of room, plenty of drive bays. Fairly quiet (can't hear it over the other 8 computers in my office). I think I'm going to buy one for myself at home to use as a homebrew Solaris ZFS cluster.

Cons: None that I can think of- heavy I guess.
