So, I run a fairly crap computer to single box 5 accounts (1 graphics card, 2 screens) - Works ok except in big PVP battles, Dalaran and to an extent other capitals.

I will be upgrading it eventually, but debating putting in a SSD for OS+WoW as I believe that will improve my performance and it would move nicely over to the next computer, now I saw in another thread that you suggested raid0 two SSDs - Is that a significant performance win over just 1 SSD?
To answer your question. Yes it is. It "Could" double read and right times too and from your hard drive. But you have to look at the whole computer. You can have the best hard drives in the world and configured for performance too, but if it is in a crap computer with a below average CPU and Video cards. It is not going to do much good. Your computer is only going to perform to the level of your weakest area (Video card, ram, CPU, Hard drives, Internet connection, are the main area's to look at)
