I don't know why those benchmarks are so slow for the top of the line SSDs.
I hit 1.5 GB/sec on my lab PC. (sequential write tests (I think, might have been read.)). The PM961 is a NVMe SSD. It plugs directly into the MB. No SATA/USB involved.

I just don't want people to think in general NVMe SSDs with a $25 adapter is never the best option for desktop PCs. Mikhail has chosen to buy a 256GB SATA interfaced SSD for ~$100. For ~$150 he could have bought a 256GB NVMe (PM961) interfaced SSD and an adapter. That pair would be 3x or more the speed of a SATA SSD. For him, the $50 was too much. For others it may not be. For me, I hope I've bought my last SATA interfaced SSD. It's a old, slow legacy solution as far as I'm concerned.
The benchmarks are for SSD-drives that take the place of hard-drives -- not motherboard attached ramdisks.
NVMe SSDs are current generation hard drives. They aren't ramdisks in any sense of the word. I bought my first one 2 years ago. The $25 adapters only negative that I know of is that you can't boot off of them typically. But, motherboards that have the built-in adapter also have boot support. Laptops with NVMe SSD support can also boot off them. fyi: it's a bit on the extreme side, but I just did some work with a client's new (and expensive) Mac Book Air. He had a 2 TB NVMe SSD in it. That's the biggest one I've seen in a PC owned by a client of mine. Greg -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
