For this you probably want the OCZ vector.  It has very good specs.

If you're bold and like to live on the edge but care about bandwidth, I 
would recommend going with PCI-e SSD cards.  They beat the living 
daylights out of their SATA brothers and sisters on performance.

Take a look at the specs from the Revodrive 3 X2 
http://ocz.com/consumer/revodrive-3-x2-pcie-ssd There is one small 
caveat,  they don't promote it for linux, in fact they don't mention it 
their OS support list, there's a reason too, this little gem smacks the 
competition and they have a product position issue since it's so 
insanely cheap for what you get.

But a well known internaut and gentoo contributer, robat2 on the OCZ 
forums, has looked at it and now there is kernel support available. So 
it will work.  And on top, TRIM support is in the latest distro's so in 
fact, linux is probably the only OS that fully supports this feature, 
very important for you'r drive to stay healthy.  (you'll end up with 4 
different drives under linux).

If you buy 2 OCZ vector's and put them in raid0 it might come close to 
what the Revodrive 3 can.  There are some things that are a tad faster 
on the Vector as compaired to the Revodrive, but price/performance I 
don't think anything comes close to it.

So pay attention to the PCI-e versions of your SSD's.  More of those are 
hitting the markets nowadays.
