Try, Try Again As Intel Releases TRIM-Enabling Firmware
TRIM clears flash pages instead of marking them as available when users delete data. That is what happens for normal hard drives, and there's no issue with them, but this creates what's called the "block-rewrite penalty" on SSDs, which occurs if a flash cell is not empty when it needs to be written to.
The new firmware version is 02HD. The short description of the update via Intel's release notes are the short and sweet:
This firmware revision has several continuous improvement optimizations intended to provide the best possible user experience with the Intel SSD.That actually means this firmware revision will fix your bricked SSDs, and hopefully not brick any ones that are working. As always, Intel warns that firmware upgrades are done at your own risk, which is what people who upgraded to 02HA found out.
