For those of you that want to use this in a M1 MacBook Pro 14 SD slot, here are the speed numbers that you can probably expect with a generic adapter:

SanDisk 1TB Ultra (SDSQUA4-1T00-GN6MA): Write: 22.6 MB/s & Read: 79.2 MB/s

These values vary slightly depending on size of files used on the tests. (See my photo)

Note that this card advertises that you can get Read speeds of 120 MB/s. 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 using 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 the speeds are lower and you will most likely see speeds closer to what I have above — so temper your expectations and buy accordingly.

I bought the 128 GB chip and I have no complaints. Sandisk makes very good storage media and I’ve never had any problems with them.

Remember however, when they advertise the SD card as 128 GB in size they (any SD card you buy) never are. I remember reading articles about this and it has something to do with the formatting and they way the device uses the surface of the card. This one laid out at 119 GB. Plenty enough for my purposes.
