TRIM feature on SSDs
TRIM (Non–RAID physical disk) allows an operating system to delete a block of data that is no longer considered in use by
SSDs. For supported operating systems, the TRIM command resolves the write amplification issue. When an operating system
deletes a file, the file is marked for deletion in the file system, but the contents on the disk are not actually erased. As a result,
the SSDs do not know the Logical Block Addressing (LBA) previously occupied can be erased. With the introduction of TRIM,
when a file is deleted, the operating system sends a TRIM command along with the LBAs that do not contain valid data to the
physical disk.
Erase physical disk data
The erase physical disk feature deletes metadata from the physical disk. This feature can be enabled only when the physical disk
is not part of any virtual disk.
CAUTION: Performing erase physical disk removes all the data from the physical disk.
