Ratings and Reviews
Works
It works with 13.4 and M1 Pro. Not sure of the accuracy of the results but it did in fact complete all passes in testing @ the 1GiB setting. My first pass was 6897 Read 6291 Write and my fourth was 69 read and 40 write..Not too sure of the algorithm or logical data stacking used to push these pases but Im pleased as one, it's free and developers work hard to do this stuff and 2 I'm sure my SSD certainly can do around 7000 read/write which is top marks for 2021 macbooks.
Works
Just tested a drive in question. One thing this does that the same style program on windows doesn’t require, is you have to specify a read/write folder location. PROTIP: Create a new empty folder. Don’t choose your system library or something.
M1 compatible!
Thank you for porting this! Finally, I have access to a useful set of numbers.
