Hi mate, Anything over 400MB/s Read and write should be ok. Scan.co.uk are doing some great offers on SSD's. I just picked up a SANDISK Hyper X SSD SataIII at 555MB/s Read and 510MB/s Write. The Hybrid drive you are refereing too is a conventional HD with spinning plates etc but it has a large cache which it buffers the data from the CPU and rean/writes it when it has spare time or the buffer gets full. If you are doing a lot of large photo edits and file transfer, you could fill the buffer very quickly and drive speeds will return to the standard levels.
