Thanks Concorde Rules you’ve given me more to think about now, I would have expected a significant performance boost over the 80GB X25 and in real world terms you've seen no difference .That’s put the performance aspect /reason for an upgrade into some doubt, especially if I’ll see little to no real difference .I kind of thought OCZ were a good make/brand to go for? I take it you’ve had some bad experiences with them?
I do quite a lot of photo/video work, using the SSD as the cache. I might have shaved a second or two off certain processes, but when it takes 20 minutes and is limited by the CPU, who cares?
Everything that takes < 5 seconds to do (which is basically everything you do 99% of the time) what is 0.25 of a second?
As for OCZ, I've personally never had them, always stuck with Intel. Every forum I frequent there are bad stories about OCZ more often than others. Intel had the stats for the lowest return rates so they get my money (and the 5 year warranty - not that that matters in this game!)
You get what you pay for! I've had four Intel SSDs, two 80GBs, a 160GB and a 300GB and they have all never skipped a beat.
Discounting Intel from the equation, I'm fairly impressed with the M4 series. So i'd get one of them.
But then again, you can pick up a 160GB X25-M second hand for ~£130-150, so why buy anything else? I picked up my 300GB 320 series for £240 from here.
As long as you do your research and not get hung up on unimportant performance stats (i.e. sequential read and write) you will be happy, whatever you do.
