    Very happy with all three services. All are being used to host several sites. So these are not idle and fresh-install numbers.

  • This seems to work better for SSD Cached
    dd if=/dev/zero of=test bs=8k count=128k conv=fdatasync; unlink test

    LSI Cachecade wont cache blocks larger than 8K I think.

    I think anything below 100 is unacceptable. I don't buy unless it's ssd cached or better now xD

    Maybe in e-peen land, but in the real world, anything over 30MB/s is perfectly fine.

    I completely agree, i notice no lag above 30 MB/s, at 20 it does at time and at high db activity (high for me, moderate for others). At 10 is visible even at apt-get dist-upgrade... Below that, i only had at home on CF card :)

    Or on Host1Free, but even then my asterisk install worked ok. So I guess DD is not the be all and end all :-)

    @Dylan, if you are on a very low plan, you need to tweak sysctl because it gets out of ram.
    It may work if the VPS is empty (I see you have a xen plan), but as memory fills the speed will degrade.
    This does not mean the disk is slower it means the dd itself has issues due to low ram available. I will double your ram temporarely, reboot and try again :)

    I received an email this morning that all customers will be upgraded to SSD next month. So I want to post here and will revisit next month, see how it's improved.

    DirectSpace must have forgotten to move me to SSD. I'm still on Xeon 5110 instead of the promised Dual Xeon E5-2630L. Anyway, will let it expire next month.

    Do you know what brand of drives?

    edited October 2013

    @Maounique
    The try above was on an empty VPS, but I just realized something was different from when I first got it: I was using CentOS this time and Ubuntu before.

    On a new Ubuntu 12.04 install it gets about 632 MB/s, on Debian 7 980 MB\s, and going back to CentOS 6 358 MB/s. None quite as fast as when I first signed up but apparently there are some very different default sysctl settings!

  • @earl said:

    It's a dmraid, I'm not sure how to check...

  • @earl, I thought I had tried proper smartctl... Apparently not.
