What is normal or acceptable disk speed on Hetzner auction server?

edited March 20 in General

Hi. Recently I grabbed i7-4770 32GB 2x4TB for 32EUR. So on the the fresh installed server, I tested its disks speed

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

and I got like 80-90 MB/s

Then I tested my current server with same spec and price except 2x3TB for the disk and got 170-270 MB/s.

So, I cancelled that new server. Was that a right decision? Because I don't know what speed I should be expecting and I got multiple times of speed on my current server.

Edit: Both have Raid 0

Thanks!

Sorry for my bad English

    A sequential write isn't going to tell you a whole lot, but that seems perfectly fine to me.

    Assuming radi1, seems fine here.

    So i wasted that rare opportunity? I don't think I will ever found that specs for the 32EUR anymore.
    Also why my current server is much faster in operation compared to the fresh installed server?

    Raid 0

    Sorry for my bad English

  • FalzoFalzo Member

    Yes wasted. Either raid 1 instead 0 or more likely just the initial sync still in progress.

    Sorry to say, but sometimes it feels deserved, when people need to learn the hard way. dd has never been something to rely on for such decisions...

    80-90 mb/s appears fine for a single disk of that type, are you sure as mentioned above the sync was not still in progress, did you configure it properly. Seems a bit silly to cancel based on a dd result.

    Seems absolutely fine especially considering most of the auction servers aren't enterprise HDDs either...

    @JohnRoe - Next time, if you have a question like this, you can always ask people in a forum like this one first or even in our own Hetzner Diskussionforum https://forum.hetzner.com/ . Or you can write us a support ticket. If you cancel too many orders, especially as a new customer, you may not be allowed to make new orders. --Katie

    This will be a good lesson for me. I made the decision based on my current server which have triple of speed. Also based on my usage which have a lot of file writing and reading.

    Sorry, but what is the "sync" you are talking about?

    Hi. I actually contacted support and they said the disks are fine. So I made the decision based on my current disk speed. I use disk heavily especially MySQL database.
    My bad, but it is a good lesson.
    Thanks.
    Also I have been your customer since 2018 and hardly cancelled any servers.

    Sorry for my bad English

  • So raid 0 is best than raid 1 then so on ...........?

    You should be using SSD's for that.

    My current server is already enough to handle, also much cheaper than SSD :)

    I don't know what to say. I got the same deal, again.

    Everything went quite well at first, I did dd test with result of something like 100-200 MB/s.

    Then I moved almost all my files (a few Terabytes) then start to activate website and stuff.
    Then somehow it get so slow, like really slow.

    Then I run dd check and g0t 17MB/s. Then I ran dd test again for a few times and out of 2 were around ~10MB/s and the other 3 tests were 100-150MB/s

    Honestly I don't know what to believe anymore. I migrated large portion of my services into this new server already. I don't know if I should continue or spend another day to migrate back to the old one.

    I know you guys said don't depend on dd tests, but what you would advice me after this scenario?

    Thanks.

    Sorry for my bad English

  • JohnRoeJohnRoe Member

    I think would just use it for a month. A price that I am willing to pay to see if it true that the dd result doesn't really affect much . I hope I don't get that 10MB/s speed anymore. Anyway It feels much slower than my previous server. I can feel it when starting/restarting systemd service, copying files, starting VNC session, although my previous server have much more running processes.

    if benchmarking at all, how about start using something more sophisticated like fio? did you check if your raid sync has finishied yet? what does the smart data of the disks look like?

  • if its a cheap deal, you can always choose to put in an extra SSD for 4/5 euros..

    put ur DB/website stuff on that and slow storage on the rotationals

    But before that, if you can see, I don't have much knowledge in this area. So bare with me, because I am trying to learn.
    Thanks.

    Also does RAID 0 sync too? If so, how do I check? There is no helpful resources on the net regarding this.

    This is the result of my smart.

    So after a few more hours of usage, I got these issues

    • ls and cd command sometimes takes a few seconds
    • pip takes a while to print first line of output
    • ffprobe takes ages
    • openresty intermittently taking many seconds to serve a webpage request even that page is an empty index.php
    • Monitoring services that I am using to monitor my websites are hammering my inbox telling my websites are down and the next minute are up (sometimes many minutes)
    • I intermittently getting MySQL has gone away which I never got on my previous server
    • Getting a lot of Lock wait timeout exceeded; try restarting transaction from MySQL because PHP script which should finish instantly, taking a lot more time to complete

    These are what I can recall and what is happening right now.

    Edit:

    • Currently my dd speed is ~50 MB/s
    • I am downloading a 20GB test file from itself and my reported Actual DISK WRITE is ranging from 1000K/s to 70M/s (from iotop). The download starts high then significantly reducing to around 10MB/s.
    • removing hundreds mebibytes of file sometimes took so long.

    Sorry for my bad English
