Using 2 ssd (for now) on Macbook Pro M1 (16GB).
- sandisk extreme 1tb (up to 1000mbps write (via TB3 have 700) but realistically get 300 mbps write max via usb-c dock). Use via usb-c dock, so 300 mbps write.
- Samsung 980 pro via TB3 enclosure. Realistically have 1200 mbps write (4x times more than sandisk). Upgraded firmware to the latest one (to fix known write speed issue).
I run 2 plots in parallel on each ssd (3600 mb ram, 2 threads) to check how will it go.
So far, much slower sandisk finished plots faster. During plotting samsung ssd had much faster write speed (was continuously checking via Blackmagic).
I am lost and looking for advice. How to understand why much faster ssd is so freaking slow in plotting…
