What is the purpose of the ATA TRIM command for solid-state drives (SSDs)?

Options:

Inform the SSD which filesystem blocks are no longer in use so it can erase them and improve write performance
Encrypt data on the SSD to protect it from unauthorized access
Compress stored files automatically to increase effective capacity
Reorganize data to defragment the SSD for faster sequential reads

Correct answer: Inform the SSD which filesystem blocks are no longer in use so it can erase them and improve write performance

Explanation: The TRIM command tells an SSD which filesystem blocks are no longer used so the controller can erase them proactively and maintain write speed. ATA TRIM support was added to the ATA standard in 2009.
