I have a SanDisk X300 2.5 7MM 256GB in my laptop with FW X3520012 currently installed.
When I check for firmware updates using SSD Toolkit it tells me there are none available, however I know that there is a X3540000 update as documented here: http://kb.sandisk.com/app/answers/detail/a_id/19261/
There is a manual update option but I cannot find a download link for the firmware?!?!
Can anyone help??
