Interesting, thank you.

I just checked out Time4VPS. Their storage VPS's have a 200 IO/s limit. At the typical 4K per IO, that's 800K bytes/sec, 1.6MB/s, or 2.1TB per month. It's a little misleading that they advertise a 10TB bandwidth limit per month on a 100Mbit/s port, when the IO limit kicks in way before that.
