thermal throttling
Do external SSDs draw so much power that they’re likely to exceed that available from Thunderbolt or USB4? What would the consequences be in terms of heat?
During the first 11.6 seconds of writing, speed was steady at 2 GB/s, then suddenly dropped to 0.7 GB/s. That’s thermal throttling for you.
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.
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.
Charging policy has changed recently for batteries in Apple’s laptops, and iOS/iPadOS devices. Your battery might also be too warm. How to check and what to do.
With a shiny new high-speed Samsung X5 SSD to test, I was looking forward to some real speed. Did it deliver good value for its high price, though?
