Fastest sata II vs solid hdd

[Kestas]

How big differnce is between this hard drives?

The fastest SATA is the WD Velociraptor, which, while noticeably faster than most hard drives, cannot hope to compete with a good SSD in almost any area.

It depends a on what you're looking for. If you want a hard drive that can transfer large blocks of data quickly (ie, copy large files), an SSD is somewhat better than a hard drive at reading, but probably not at writing.

But if you're looking for a drive that can do lots of small random I/Os very fast (which is what's important for booting and starting programs), then an SSD is miles ahead of any hard drive, even hard drives in a RAID array.

sata is an interface, not a storage medium.
