Phoronix: Samsung 980 PRO PCIe 4.0 NVMe SSD Linux Performance

The Samsung 980 PRO PCIe 4.0 NVMe solid-state drives are now available from Internet retailers. For those wondering how these SSDs compare with EXT4 under Linux against other PCIe 4.0/3.0 drives, here are a variety of benchmarks.

What happened? When did the PRO series basically became an EVO?

Although I didn't see a price rundown I would imagine the Sabrent is the best bang for the buck by far as well as taking the geometric mean crown. Well done Sabrent!

How does it manage to be worse at SQL than its own last gen?

For me this can't be possible. Everything points to 980 pro must be better then 970 evo in every point

To get the max performance on these drives of "up to" 1 million iops read/write, you need to use a small lba range on the drive to stay within the limits of the intelligent cache.

You don't say you need to introduce short stroking for SSDs? That was a thing for HDDs only, I thought. :-O

Guessing there are some firmware woes with the 980 PRO under Linux but haven't yet seen anything to confirm that.

That would be the first thing to look at but these tests are more or less consistent with a couple of other benchmarks I have seen under windows. Maybe Samsung is being super conservative coming out of the gate across the board. Or maybe these are just designed for a specific use case.

It's worth to note that the 980 PRO is TLC instead of 970 PRO's MLC. Not tested here, but it's worth to know when considering upgrading from it.
