I have a gaming PC, but i only have a relatively small HDD. I have saves up around £100 and wondered weather to buy a Samsung 840 evo 250gb, or buy 2 or 3 7200gb HDD's and run them in a RAID formation. A RAID formation would offer more storage space for the money, but is it reliable and would it give me the performance of that particular SSD? What do you think? I would appreciate the help!

Motherboard: M5A78L-M/USB3

An SSD is faster than two HDD's in RAID 0.

Solution?
Get the 840 EVO, and 1 HDD. And that particular SSD is your best choice.

SSD + 1 HDD would be your best options. OS and games on SSD. Movies and music/ other apps on the HDD

would not running multiple HDD's in RAID not give the speed of an SSD but alot more storage space?

No.
And it will add a lot more complexity/fail potential.

A fast hard drive may reach 200mb/s,
Two of them in raid-0 would theoretically reach 400mb/s.
But... that is only for artificial sequential benchmarks.
In actual usage, somewhat less. That is helpful for level loads.
In small random I/o service time might be 10ms for a 10k wd raptor.
small random I/o is what windows does 90% of the time.

By contrast, a modern ssd on a 6gb sata port can reach 550mb/s and will have a service time 50x faster.

The 240gb EVO is a great choice. If it approaches full, move off larger files to a hard drive.
