Progress benchmarking performance of internal SSDs in M1 Macs: tests of 400 files totalling over 130 GB written and read in less than 50 seconds. And results.
SSD
Fast compact external SSDs are prone to thermal throttling. This is demonstrated during tests writing 96 files, when transfer rates fell from 2 GB/s to around 700 MB/s.
Although little more expensive than good Thunderbolt 3 cables, what are the differences in Thunderbolt 4? When do you need a new TB4 cable?
It started with wanting to benchmark SSDs, passed through robust linear regression, and is now diving deep into linear programming and matrices.
How to install macOS on your M1 Mac’s external SSD. But it comes with a snag: you can only install 11.2 and can’t update it to 11.2.1.
Making an external bootable SSD for an M1 Mac has proved tricky. Has this changed in macOS 11.2? If you’ve already got 11.1 running on one, how do you update it to 11.2?
Improved tests, statistical analysis, and interface, together with a 21 page Help book detailing its range of tests in 5,000 words. Ready to use for real.
Detailed tutorial steps you through getting accurate and reproducible benchmarks for your disks. Also further projects and tests you can try.
Now with proper random write and read tests, sophisticated analysis including group medians and linear regression, and detailing reporting.
Can M1 Macs really defy the laws of physics and read files from SSD at around 12 GB/s? Or are their performance improvements more modest?
