- dv_dt 10y agoIf you don't test read with some writing, you might be misled by performance of an SSD. 100% read or 100% write are very different from 50/50 or even 70/30 r/w. The mixed bandwidth typically drops by a lot. If you haven't pre-written some data, that dd test might not even be touching the flash. Just reading internal metadata... But yes, nicer M.2s will perform better!
