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=fdatasync

  • You 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"

    I/O speed(1st run) : 236 MB/s
    I/O speed(2nd run) : 231 MB/s
    I/O speed(3rd run) : 254 MB/s
    Average I/O speed : 240.3 MB/s

    agreed.

    aged VPS-SSD-2 in GRA1:

    dd if=/dev/zero of=test_$$ bs=64k count=16k conv=fdatasync

    1073741824 Bytes (1,1 GB) kopiert, 3,95791 s, 271 MB/s
    1073741824 Bytes (1,1 GB) kopiert, 2,36177 s, 455 MB/s
    1073741824 Bytes (1,1 GB) kopiert, 2,48998 s, 431 MB/s

    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
