A quick note to users of Intel SSDs - specifically for owners of the 335 Series. Intel has updated their SSD Toolbox app to v3.1.2. This app is used for various tasks on Intel SSDs, such as secure erasure, performance optimization under Windows, and TRIM through RAID-0 under Intel RST / ICH / PCH motherboard SATA controllers. This update is significant in that it can in turn update the firmware of the Intel 335 Series SSDs to correct a bug in how those drives report wear. This bug was initially discovered by Kristian Vättö, over at Anandtech.
If you have a newer version of the SSD Toolbox, F9 will be listed as "Total NAND Writes", and list that value in MB. The issue with the original 335 firmware was that it incorrectly calculated the wear (the Wearout Indicator - E9 above) such that it would list the drive as worn out after ~1,000 total flash cell erase cycles (i.e. 1,000 x the capacity of the SSD). The firmware update corrects this value to ~3,000 cycles, which is more appropriate for the rating of IMFT 20nm flash. Updating should be non-destructive, but you should backup just in case. The update is not urgent, in that it only corrects how the drive does the math to calculate E9. The Wearout Indicator will change to the correct value after the update, regardless of when it is applied. Additionally, if the MWI reaches 0 prematurely, it should have no impact on operation of the SSD.

Introduction, Specifications and Packaging
It's been a short while since we've seen a consumer SSD release from Intel, and with pressure coming from Samsung in the form of lower cost/GB 20nm flash, it was high time Intel followed suit. The Intel 335 Series launches today, and is essentially the same SandForce-driven product as their SSD 520 Series released earlier this year. The key change is this time around that controller will be driving Intel 20nm flash. This should bring a much needed price reduction to the SSD arena, as the 335 is not being marketed as a 'Pro' unit (like the Samsung's 840 Pro). So long as this new model performs similarly to the 520 Series, we should be in for a good, low cost SSD just in time for the Christmass shopping season.
