For non-apple ssd devices, one needs to:
-- check and update firmware
-- figure out how to enable useful options like noatime (fs) and trim, etc
-- OR perhaps, install a 3rd party utility to help with SSD optimization
-- also, watch out for time-machine 'local backups' which are temporarily stored back on the ssd until the next time the external time-machine back-up device is re-connected (this uses additional disk-space, and can be disabled) Crucial-m500-iso-firmware-update-mu05-en. Crucial.com - SSD support. WARNING: The firmware update process is done entirely at your own risk.
Before initiating the update process be sure to backup or make copies of all important files. If the firmware process is interrupted your solid-state drive may not function properly. UEFI-based Systems: During validation of this firmware update we noticed instances where our update tools do not recognize the SSD with some systems using UEFI. The target device is not recognized as an updateable device during the reboot process. If this happens, the firmware update will not occur, and you’ll retain the firmware version you started with. If you have a Dual Boot system we recommend using the Manual Boot Process as opposed to the Windows Update Utility. If you have more than one m4 in your system, note that the Windows Update Utility will update all eligible drives automatically.
