Kindle is Linux and SSD
Authored by: ailuromancy on Tuesday, October 23 2012 @ 12:24 AM EDT

Ask Linux to delete a file on an SSD and the kernel will use the TRIM command to tell the SSD that the data for the file is no longer required. The SSD will erase the blocks that contain the data so it can choose the next block to write from a larger list of erased blocks and improve wear levelling.

Recovering a deleted file from a Linux file system was never as reliable as it was for with DOS. Recovering a large deleted file from an SSD is very unlikely. A small file might survive for a while if it is on the same block and some other files that are not deleted. At some random time in the future, that block will be garbage collected: the useful data from several full blocks gets moved to a smaller number of erased blocks to increase the number of available erased blocks.
