OVH VPS vs Hetzner Cloud - disk performance difference

As an Online.net server price increase refugee, I bought two VPS's, one from OVH:
- VPS1 SSD (1CPU, 2GB, 20GB) 2,99€
And one from Hetzner:
- Cloud CX11 (1CPU, 2GB, 20GB) 2,49€
My question here is only one: disk performance.
I know Hetzner uses NVMe but...
Using bench.sh, OVH result:
I/O speed(1st run) : 66.9 MB/s
I/O speed(2nd run) : 77.3 MB/s
I/O speed(3rd run) : 77.8 MB/s
Average I/O speed : 74.0 MB/s
Hetzner result:
I/O speed(1st run) : 282 MB/s
I/O speed(2nd run) : 401 MB/s
I/O speed(3rd run) : 414 MB/s
Average I/O speed : 365.7 MB/s
Is this OVH result normal?! It seems too low, even for lowend SSD, no?

The SSD is shared with many users. Hetzner uses NVMe SSD's. So the performance difference is not a shock
EDIT_____
Also, is that test for sequential writes? reads? 4k writes? reads? Because those values are quite normal for 4k writes
From what I see, this is the command used:
dd if=/dev/zero of=test_$$ bs=64k count=16k conv=fdatasyncYou should test google cloud
I dunno what your OVH VPS is smoking. Here is one of mine:
Public Cloud S1-2 "10 GB SSD Local RAID 10"
agreed.
aged VPS-SSD-2 in GRA1:
Yeah that's what mine usually are but I did buy 1 the other week which had piss poor writes like OP posted.
surprise - iops and speeds differ from hypervisor to hypervisor.
If a node is busy disk wise, it will perform worse than a node that is not busy disk wise.
You pay pennies - if you're unhappy go for another solution.
It's very simple.
OP is just curious, same as me. ~70MB/s is indeed questionable for SSD
