Hello, I have bought a wd black and I have done a performance test, according to some benchmarks it should have an average write rate of 2gb/s but I have less than 400mb/s.

Attach screenshoot with the benchmark: https://ibb.co/7Vs6Nfj Does anyone know why this happens?
Hard to say..you don't tell us what this drive is plugged in to, what kind of controller, or what version/distro of Linux. Is this a virtual machine or physical? And are you *SURE* you didn't buy a counterfeit device?
You still don't say what this is plugged in to...what brand/model is your computer??? The very basic info you posted isn't much good. The PCIe slot you have may be a slower speed; if it's a PCIe x16, it'll run at 1/16th the speed...until all 16 threads are taken up, and it'll go full speed. And are you using the latest kernel, and have all the patches/updates done??
And again, you were asked if this was a virtual machine or physical, but assuming physical. What kind of file system is on that drive, also??
FYI, If you actually look at data above he does give his computer motherboard :
Code:
Manufacturer: Micro-Star International Co., Ltd.
Product Name: MPG X570S EDGE MAX WIFI (MS-7D53)
And is on Ubuntu 22.04.... Doesn't appear to be in a VM.... Also looks like disk access has overhead of crypt and lvm...
All true....still don't know what brand/model, since some manufacturers have their own BIOS tweaks.

Here is Toms Hardware review of the device if that would help look at reviewed speeds:
The NVME drive is probably not the issue...it's the port it's plugged in to, or the kernel version (if patched) that they're running. Known issues with some Ubuntu kernels and NVME, specifically around speed.

is Toms Hardware review of the device if that would help look at reviewed speeds:
Yes, the reviews says read ~5gb/s and write ~2gb/s but in my case is read ~5gb/s and write to ~360mb/s. The LVM is used for Ubuntu only on other wd black disk (1TB), the benchmark is tested on other disk (2TB for Steam files).
Page 2 of the article referred to in post #6 explains you're getting exactly the same poor extended write performance as experienced in that test - when write cache is saturated, write speed drops down to typical SATA SSD speeds.
cat proc/interrupts looks OK, but fdisk -l shows a disk without any partition. This is very unusual for HDD/SSD. Is this setup required for "gaseous H₂O" aka "steam" or has setup failed on /dev/nvme0n1?
