File Shredder securely erase files beyond recovery. Using this software, you can permanently erase data from the hard drive of your PC or from external drives. Semivio File Shredder uses government-approved file shredding algorithms, which ensures maximum security and makes deleted files unrecoverable. It enables you to erase files that contain sensitive information so that they don’t fall into the wrong hands. Semivio File Shredder is very easy to use. The program ensures secure file deletion and guarantees that deleted files cannot be recovered even with the help of professional file recovery software. Semivio File Shredder is a privacy protection program that allows you to securely delete confidential files to prevent recovery of deleted data. To continue, you must subscribe registered version of the software where you can use the application for infinite files. The key is to find an optimum algorithm which maximizes them both.Semivio File Shredder gives you a free trial version for 12 files. Each time data are relocated without being changed by the host system, this increases the write amplification and thus reduces the life of the flash memory. Unfortunately, the process to evenly distribute writes requires data previously written and not changing (cold data) to be moved, so that data which are changing more frequently (hot data) can be written into those blocks. In a perfect scenario, this would enable every block to be written to its maximum life so they all fail at the same time. For this reason, SSD controllers use a technique called wear leveling to distribute writes as evenly as possible across all the flash blocks in the SSD. a particular block were programmed and erased repeatedly without writing to any other blocks, the one block would wear out before all the other blocks, thereby prematurely ending the life of the SSD. The result is the SSD will have more free space enabling lower write amplification and higher performance. This reduces the LBAs needing to be moved during garbage collection. This informs the SSD that the LBAs in use can be erased and reused. When a file is permanently deleted or the drive is formatted, the OS sends the TRIM command along with the LBAs that are no longer containing valid data. Because of this, the SSD does not know the LBAs that the file previously occupied can be erased, so the SSD will keep garbage collecting them.The introduction of the TRIM command resolves this problem for operating systems which support it like Windows 7, Mac OS (latest releases of Snow Leopard, Lion, and Mountain Lion, patched in some cases), and Linux since 2.6.33. If the user or operating system erases a file (not just remove parts of it), the file will typically be marked for deletion, but the actual contents on the disk are never actually erased. When an LBA is replaced by the OS, as with an overwrite of a file, the SSD knows that the original LBA can be marked as stale or invalid and it will not save those blocks during garbage collection. This will cause extra wear on the SSD so on life span and performance.TrimTRIM is a SATA command that enables the operating system to tell an SSD what blocks of previously saved data are no longer needed as a result of file deletions or using the format command. If Freeraser do not support Trim, then LBAs are not Trim marked so SSD will keep track of the data on them until they are reused. if yes then all LBAs on the are marked for deletion, or when you quick shred tall LBAs are TRIMed and thus marked for deletion.
