|
- SSDs can be overprovisioned in order to improve performance by leaving unused space the SSD can use internally.
|
|
|
Factories typically reserve some minimum size appropriate to the drive, but users can overprovision further by leaving space unallocated/unpartitioned at the end of the drive.
|
|
|
It's typically not needed to overprovision newer SSDs.

+- After receiving a new drive or after transporting an existing drive, you may want to run a SMART conveyance test,
|
|
|
+ which is similar to a short test but targeted at this scenario.
