SanDisk rolled out a firmware update for its Extreme Series high-performance client SSD. The new R211 firmware corrects outstanding bugs related to TRIM and garbage collection, speeds up drive initialization time at boot, and other minor errors. To begin with, the new firmware improves TRIM delay (delay between the SSD receiving TRIM command, and finding a convenient time to "take out the trash"), as a result TRIM and its related garbage disposal performance is greatly increased. The firmware also improves error handling and power management. Next, the new firmware reduces boot-time normalization of SMART attributes, reducing POST initialization time of the drives. Lastly, a minor bug related to temperature-reading is fixed. The update is recommended for users facing issues with SanDisk's fastest client SSDs. The firmware can be updated using SanDisk SSD Toolkit, its latest version is linked below.

Thanks for the info, btarunr.

The firmware update went smoothly. No data lost and no glitches.
It did, however, reset my SMART data "device power on count" as it is now 1 (one) after the first boot into windows after the update.

No great performance differences in read and write; however access time went from 0.19 to 0.12.
The temps shown by the drive were in -line with the other drives in that same area and the same as before the update.

Except the SanDisk drive is based on a SandForce controller and Crucial uses Marvell...

Great..my keyboard doesn't work after booting with USB. Too lazy to do anything about it right now.
