I recently "upgraded" from a 16 month old 120GB OCZ Summit drive to a new 25nm 180GB Vertex 2. Each was running the latest firmware for the drive (1.28 for the Vertex2 and 19C1 for the Summit). As you know, the Vertex 2 is based on the Sandforce controller and the Summit on the supposedly shameful Samsung controller. Usage wise, the Vertex 2 is faster. I run Star Trek online through Wineskin and the Summit had noticibly longer "load" times. FPS in game is the same, but load screens were longer with the Summit. Many apps still launch in one bounce on the dock, such as Outlook, Word, Firefox. PS5 and the rest of the creative suite still take only 3-4 seconds to load. So app load times didn't really improve, but I haven't used all of them yet. Synthetic benchmark wise - I'm getting mixed results. Xbench (yes - the loathed and outdated tool that shouldn't be used but still is) - reports interesting results. Slower sequential speeds but much faster random speeds. Write @ 4k improved, which is where the Summit always performed dismally in every benchmark out there. How much that translates to real world performance I can't say. AJA test shows a much more consistent result with the Vertex 2 over the Summit. Even after a secure erase to restore the Summit to pristine condition, it had several spikes in the writes. The Vertex 2 holds steady at 239 mb/sec read and 193 mb/sec write on the 256 and 512 mb whack test. The Summit came in at 210 mb / sec read and 160 mb / sec write on the same tests, but the line wasn't as smooth. I will chalk that up to age of the drive. So after all of this, I'm not sure the "investment" was as sound as I had led myself to believe it was. I already had a fast machine with low power consumption (the Summit has the lowest idle power consumption of all SSD's I've researched). I now have a marginally faster machine, but again - not that much faster. Perhaps there is a break in period? Or as is suggested in the threads over at OCZ - this may just be how the 25nm devices benchmark. Either way, the Summit isn't the POS I was led to believe and tell myself it was. It may have a second birth in my PS3 rather than make it's way to eBay. Just posting up for awareness and to see if anyone else has made the switch.
