It would be nowhere near as fast as an SSD.
The key to SSD speed is not necessarily raw throughput (megabytes per second), but rather the lack of random access time. The drive can move from file to file, anywhere on the disk in approx 0.1ms. Compared to a spinner drive that usually runs around 12.0-15.9ms....that's a huge improvement.
The key to using an SSD is keeping your OS and applications on the SSD...and keep a spinner drive for data and storage. Unfortunately, for gamers...SSD's aren't ideal as these installs consume huge amounts of disk space and can fill an SSD in a heartbeat.
I have an 80GB SSD and have a couple of games installed (Call of Duty World at War and Star Craft 2), and I'm at about 50% used on my SSD.
