Test VPS IO Speed

[tr0gd0r]

Can someone run this command on their VPS/VDS and let me know the output?

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

This command will test the hard drive speed. I am interested in purchasing one, but would like this information first.

The result will vary depending on the level of other customer I/O at the time, the type of RAID used on the physical machine, and the exact type of drives used -- so a single value will not be a good representation of average performance or what you would receive as a customer. (Your test line also tests only sequential writes and and uses a small block size, so it's an unusual workload.)

If you need to run tests, the best plan would be to start a free trial and contact us if you feel that the result of a test battery that better mimics your real usage is lacking in some way. If you have a particularly I/O intensive application, you should also consider purchasing SSD space.

With those caveats, here's what I received from one of our test VDSes, on one of the newer machines.

# dd if=/dev/zero of=test bs=64k count=16k conv=fdatasync
16384+0 records in
16384+0 records out
1073741824 bytes (1.1 GB) copied, 4.36528 s, 246 MB/s

I understand that its not a realistic test, more of a synthetic benchmark.

Thanks for the results. Were those taken from a spinning drive array or from an SSD?

That result was from our standard storage option, so it was backed by a RAID of spinners.

15K SAS?
