Hmm, maybe I'm getting mixed up in what M.2 actual means. I though M.2 was NVME. BTW, before my new purchase, I never heard of M.2 or NVME. Its shows how out of touch I've been in regards to new hardware technology. It was the sales person who suggested it after I initially when for the "regular" 850 EVO SSD. These are the prices from the local store that I got my system from. Samsung 250GB SSD, 960 EVO Series, m.2 (PCIE), Read up to 3200MB/s, Write up to 1500MB/s $189AUD Samsung 250GB SSD, 850 EVO Series, m.2 (SATA), Read up to 540MB/s, Write up to 500MB/s $145AUD Samsung 250GB SSD, 850 EVO Series, SATA III, 7mm, Read up to 540MB/s, Write up to 520MB/s $144AUD That's about a 30% difference.
