TRIM is supported by Windows 7 and by some late model SSDs, but not by older Windows versions. As an SSD is used with files that are deleted or changed frequently, the performance can drop unless the drive (and operating system) support a technology called TRIM that wipes out deleted data blocks as soon as the file using the blocks is deleted. Overwriting a block was previously used involves copying the contents of the block to cache, wiping the block's contents, delete the block to be overwritten from cache, writing the new data to cache, and rewriting the block with the new data. SSDs store data in blocks rather than in sectors as with magnetic storage. With SSDs, the erased file situation is even more complex. As long as the operating system does not reuse the space occupied by a file with another file, the "deleted" file can be recovered. However, the file could be recovered days or even weeks later with third-party data recovery software. If you use Shift-Delete to bypass the Recycle Bin, the space occupied by the file is marked as available for other files. If you use the normal Windows delete function, the "deleted" file is sent to the Recycle Bin until the space it uses is required by other files. When you erase/delete a file from your computer, it's not really gone until the areas of the disk it used are overwritten by new information. Sure, you could erase the contents of the drive, but keep this in mind: the act of erasing a file does not remove it from a storage device.
