For those of you that want to use this for a M1 MacBook Pro 14 - it fits fine, and in fact, it says that it is for a MacBook Pro 14 on the packaging that you receive (see my photo).
What speeds can you expect? I performed speed tests with two different grades of Sandisk microSD Cards on my base-model MBP14 (8-cores) and these are the results:
SanDisk 1TB Ultra (SDSQUA4-1T00-GN6MA): Write: 22.6 MB/s & Read: 79.2 MB/s
SanDisk 1TB Extreme (SDSQXAV-1T00-GN6MA): Write: 53.1 MB/s & Read: 83.2 MB/s
These values vary slightly depending on size of files used on the tests. (See my photos)
Note that these cards advertise that you can get Read speeds of 120 MB/s and 190MB/s respectively. However, keep in mind that those speeds are under ideal conditions and using SanDisk’s own reader that uses a proprietary protocol to achieve that.
Realistically, most of us will be confined to the UHS-I speed of our hardware. In my case on the MBP14, that is 104MB/s for the slot. Without the proprietary Sandisk hardware, you will most likely see speeds closer to what I have above — so temper your expectations and buy accordingly.
