About the Intel

SSD Optimizer
The Intel SSD Optimizer helps an Intel SSD retain its out ‐ of ‐ box performance by
removing deleted data files from NAND flash management blocks on the SSD using
Trim functionality (a command that allows an operating system to inform an SSD
which blocks of data are no longer considered in use and can be deleted).
Example: When you delete a file on your system, the operating system marks the file
for deletion but does not physically erase the file. Because an SSD does not know
which files are deleted, the SSD continues to think all files contain valid data. This
situation causes the SSD to continue managing deleted files in addition to valid data
in the SSD.
By running the Intel SSD Optimizer, the tool identifies which files you have deleted
and communicates that information to the SSD. This notification allows the SSD to
clean up internal management space, thus eliminating the need to manage the
deleted files.
You can schedule the Intel SSD Optimizer to run automatically on a weekly, daily, or
monthly basis or you can manually run it at any time.

SSD Optimizer Requirements
The Intel SSD Optimizer runs on Intel SSDs only. All Intel SSDs are supported except
first ‐ generation (G1 50nm) Intel SSDs. To identify your Intel SSD, see Identifying
NAND Lithography of an Intel SSD. The X ‐ 25V and Series 320 SSDs released on NCR
products are also supported.
Before running the Intel SSD Optimizer, make sure the Intel SSD has the latest
firmware installed. See Checking for Firmware Updates.
Note the following before running or scheduling the Intel SSD Optimizer:
• Do not run the Intel SSD Optimizer when a backup is in session.
• Do not run the Intel SSD Optimizer if the Intel SSDs are in a RAID configuration.
• Make sure Intel SSD Optimizer sessions are scheduled to run when the computer
is on. The Intel SSD Optimizer does not wake up or turn on the computer to run a
scheduled session.
