Update for Crucial M4 SSDs regarding SAS expanders/RAID cards

000F - worth looking at if you're using them in a server, by the looks of it. Time to update all of ours - I'll be interested to see if there's any performance difference.

This should now fix the issue with LSI SAS controllers.

Release Date: 04/11/2012
Firmware for the m4 SSD is being updated from version 0309 to 000F. The m4 is updatable to this new firmware starting from versions 0001, 0002, 0009, or 0309 in a single step. If updating from an early version directly to 000F, all interim improvements will also be included (please see Release Notes for version 0002, 0009 and 0309 for details).
Changes between version 0309 and 000F include the following changes:
Improved compatibility with certain SAS expanders and peripheral RAID cards.
Improved throughput stability under extremely heavy workloads.
Improved data protection in the event of unexpected, asynchronous power loss.
This firmware update is recommended for all drives currently in the field if the end user is experiencing any of these symptoms.
