Trimming Activity of Solid-State Drives


The primary source for storing digital information has been remained constant for the last two decades, in the form of magnetic disks. However, a sudden shift has taken place in the data storage technology during the recent years where the transistor-based devices are being used as primary storage devices for storing complex data. There are many reasons due to which the manufacturers are shifting their platform from magnetic disks to solid state drives which uses transistor chips and this change is creating problems for the forensic investigators to investigate on the digital evidence.

The deleted information can be easily retrieved from the hard disks by following specific guidelines, where as in solid state drives it is almost impossible to retrieve the lost data when TRIM command is enabled. SSDs can sometimes sanitize data all by themselves even if they are not connected to any interface. This paper gives an overview of the hard disks and solid-state drives for data recovery and mainly focuses on the functioning of TRIM command in solid state drives.
