Using 140 files of sizes 10 KB – 2 GB, the M1 read files significantly faster than a T2 Mac, but the latter wrote files slightly quicker. Highest read rate on the M1 was 10.8 GB/s, which seems almost incredible.

A new version of Stibium which performs series tests raises further questions about benchmarking SSDs on Intel and M1 Macs. And is an X5 worth the extra cost?
If you’ve been unable to create a bootable external disk to use with your M1 Mac, this explains what you need and its limitations and quirks.
A new version using Mach absolute time brings accuracy to a few microseconds, and a Help page. Tests progress well, and continue to make interesting comparisons.
Developing an app to assess the real-world performance of SSDs: initial results from a T2 Mac and an M1 Mac mini are different but there’s no simple answer to which is the faster.
A lot safer than racing through the English countryside in the dead of night, and perfectly legal. So why can’t we get a clear answer to how well an SSD performs?
How fast is the internal SSD? Benchmarks range from around 2.7 GB/s up to nearly 20 GB/s. Which are right? Some new figures, in need of more measurements.
Here are several good reasons that Big Sur will need more storage space than previous versions of macOS.
This can now be incorporated into your own scripts, to check the integrity of important files automatically.
Can you use error-correcting code to repair very large files, for example of around 20 GB or more?
