"Significantly faster" is for synthetic benchmarks. In real world usage you likely wouldn't be able to tell the difference between a "slow" SSD and a "fast" SSD (as long as the slow one isn't a crappy one like the original Jmicron).
Glad you're enjoying the SSD. OCZ has some software that will tell you the good or bad news about which revision you have. 🙂 Since you're already there you may want to check for updated firmware. They release them often... a little too often. If you do find one, do backup. Win7 makes it ridiculously easy especially if you already have Win7 bootable media.
Yeah it was a total nightmare trying to get the firmware updated to v1.32. It wound up borking my drive, and I had to re-flash it from Linux to get it working properly, plus I had to re-install Windows. 🙁
For whatever reason, the Windows firmware upgrade software did not work out for me.
Anyhow, I'll try to post some benchmarks of the drive later. So far it seems as though I got the older revision which is probably a good thing.
