I upgraded from a Vertex 2E to a Vertex 3, and no, though the benchmarks are wonderfully improved, particularly on the read speeds, I don't think the upgrade was worth the Â£90 I spent. If I had spent a bit less, perhaps.
I don't have exact numbers, sorry. I appreciate that's what you probably want. What I did observe is that my booting time is pretty much the same between both. The Vertex 3 might have shaved off one second but that's it. The loading times of programs and games are also about the same, again perhaps shaving off a second or two maximum for heavy programs such as 3ds Max / Adobe Photoshop.
Far too many people grab two of these for a RAID0 configuration that offers them read speeds of like 1GB/s when in reality, it makes very little difference at this juncture. The loading time between a fast HDD for something could be, say, 15 seconds. A Vertex 2E might be able to do it in 3 seconds. Then the Vertex 3 might be able to do it in 2 seconds. A RAID0 might shave off a tad more but that's pretty much where you're at. Human perception of time naturally stops you noticing the difference anyway.
The fundamental question here is - if you have a Vertex 2E and want to upgrade to a Vertex 3, unless it's a very cheap or free upgrade, don't bother. If you have money for either and are trying to decide which is a better buy, just get the fastest (the Vertex 3) and be happy with it (the price difference between them isn't as huge as I paid for the upgrade). As for RAID0 configurations, only bother if you feel you need your online ego boosted and you have plenty of money to burn. I hope this provides some perspective!
Oh and remember, currently the Vertex 3 is having firmware problems with hardware and settings. OCZ and SandForce are working hard to identify the causes and supplying fixes. I hear Corsair suffers from the same, same issues considering their pretty much equal Force 3 SSD. I encountered no problems with the Vertex 2E but the Vertex 3 has given me problems from day one. It's very new and problems need to be ironed out. However, you can help avoid problems by keeping the stock 2.02 firmware and not upgrading it to 2.06 (just yet).Edited by Gib007 - 6/7/11 at 4:44am
