Can deleted data be recovered from an SSD?

Yes, it is possible to recover deleted data from an SSD (Solid State Drive). However, the process of data recovery from an SSD is more complex than from a traditional hard disk drive (HDD).


When data is deleted from an SSD, the data is not immediately erased from the drive. Instead, the SSD marks the space occupied by the deleted data as available for new data to be written. This means that the deleted data may still be present on the drive until new data is written over it.


However, SSDs use a process called wear leveling, which spreads data evenly across the drive to prevent overuse of certain areas. This means that deleted data may be scattered across multiple memory cells, making it more difficult to recover.


Additionally, SSDs employ a process called TRIM, which is designed to optimize performance by erasing data blocks that are no longer in use. This means that if TRIM is enabled on the SSD, deleted data may be erased more quickly and may be more difficult to recover.


Despite these challenges, it is still possible to recover deleted data from an SSD using specialized forensic tools and techniques. These tools can analyze the SSD at a low level to search for and reconstruct deleted data. However, the success of data recovery from an SSD depends on various factors, such as the amount of time that has passed since the data was deleted, the extent of wear leveling and TRIM, and the specific methods used by the forensic tool.
