I have two of these drives, so I re-ran the update with the 3.12 firmware's toolbox, and it destroyed the first one (black chassis). It completed without error, asked to shutdown and the drive is now bricked. Since I obviously didn't trust that updater anymore, I used the updated toolbox utility distributed with the Vertex 4's new release version of firmware 1.4 to update the second one, which has a silver chassis. The silver drive completed successfully and requested shutdown the same as the first drive, but still worked after rebooting although it just reflashed the drive with the same 3.12 that was on it. I would suggest that you document in your reviews the firmware revisions tested. Both of these drives are "new" RMA swaps for my original two that had a constantly growing number of defects and read errors, which I flashed to 3.12 and shelved until a new update was released since both showed the same small number of reallocated sectors immediately after updating to 3.12 (the stock firmware did not even have a SMART table!).
I'd be quite wary of OCZ, they are notorious for releasing imploding drives in these Indilinx product lines (eg: early Vertex Plus's, which was solved after 3.50 but took them ~6 months to release) and manipulating public perception of what you're buying (eg: Indilinx-infused meaning a completely different architecture Marvell controller in the Petrol/Octane/Vertex 4 with custom "Indilinx infused" firmware). It appears to me that they've waited until they have an internal "stable" release to provide you with a drive to review, but this does not reflect the drives everyone has been buying for nearly 6 months and which cannot be "fixed" with any publicly available firmware.
If you could document in your reviews the firmware revision they have provided you with, we can tell when they're essentially manipulating the media to gloss over their past mistakes--which is exactly how I'd describe what they did here. Otherwise, it compromises the integrity of what you're doing here as user experiences with these drives are vastly different than what you have seen in your review evaluation. We know from your Vertex 4 1.4RC firmware release evaluation that your reviews are accurate and not knowingly glossing over deficiencies & stability issues, but I think OCZ pulled a fast one in this case. I'm a huge fan of your site since the early 2000's and it's been my #1 storage resource since the days of Eugene...keep up the good work!
