Are these NVME disk speeds expected?

Seem a tad bit on the lower end
Debian
Slower than spinning rust
What provider? No, definitely not for name and shame. Feel free to dm.
That's slower than even typical VPS spinning drives.
If that's the correct product name, checking online it lacks a DRAM, so that would seem to be why. But the 1M/s seem low.
Well, this is a very know provider here in the community, however, I'm not going to name it or tag the provider.
However, after providing them with multiple tests, their final reply:
From Canada?
Based on the hostname alone and doing a little low end detective work (pasting hostname in google search) you can check the provider in question
@plumberg69
i love germania quality:
netcup's customar service
contabo's vps performance
and now this
reguards
It's Friday
Can't do much work
Need info directly
I have 2 VPS with NVM disks and here are their speeds.
and
To be honest between 2 VPS, the latter one has slower disk speeds even it's NVMe, I will file a ticket about this, just to see what they say.
19.97 GB/s is incredibly fast.
It's running on a 6502? BBC or C64?
That beast is: 2 Cores @ 3099.998 MHz -AMD EPYC 9554P, really nice one.
What provider is the fastest one?
They are both @naranjatech.
Can you show geekbench 6 too please?
I've still got PCs with ram that isn't that fast.
This is from another NVMe server. I got 4 deals from @naranjatech for some reason
One of my VPS beats this dedi server:
I have another server with them : AMD Ryzen 7 5800X 8-Core Processor 1 @ 3800.000 MHz
Even without the DRAM it should have full read speed and maybe a bit slower write speeds when the drive gets more full / the SLC write cache is exhausted.
I'd say this is waaaaaaay too slow and there has to be something wrong.
SNVS2000G is not exactly a top of the line, but faster than SATA.
Maybe somehow during your tests you've exhausted the SLC cache. The NV series likely have QLC NAND.
thats an entry level consumer grade NVMe
here's one which is production ready vps

I agree Rubben, though as CyberneticTitan mentioned, it could've exhausted cache. Also this one seems to be QLC NAND, which from my expierience doing dd block-by-block would slow down to ~20MB/s on Micron QLC NAND.
This drive is notebook grade.
I asked this and the answer I got was:
Which makes sense
This is SSD speeds from my LE-1 on OVH. So my SSD speed is faster than your NVMe
It's on SCSI with Raid1
No, this is slower than a regular machine's hard drive speed, which is usually above 1GB/s.
Agreed, directly writing to QLC is insanely slow. However, the write cache being exhausted should not slow down read speed. So it's fishy either way.
