Extending the Life of the Z-Drive R4
Disable Defragmentation
Solid state disks do not require defragmentation, as it is a process typically meant for HDDs; unlike
traditional hard drives, SSDs do not gain performance improvements from defragmentation but instead
it produces unnecessary writes to the drive, shortening the lifespan of the Z-Drive R4. Since SSDs are
based on flash technology, they must also be maintained differently. Please follow the instructions
below to check and disable the Disk Defragmentation Scheduler in Windows 7 (other versions of
Windows should be similar).
Note: Defragmentation is unnecessary on the Z-Drive R4.
