Lately I've been testing amazon EC2 and moving my virtual machines there. So I got a chance to test some EBS / instance storage block devices.
And my t1.micro instance got EBS performance like this:
And as you can see, this performance is not amazing. Slow writes, slow rewrites, nice reads (but still slower then 7200 rpm hdd). So you can't expect fast IO from t1.micro. But what amazes me is seek amount, almost like ssd storage. Strange but true. Of course those results varies on (I guess) resources available.
