Make Sure Defrag Is Off On Your Ssd

Make Sure Defrag Is Off On Your SSD

 

In light of the popularity of Solid State Drives, most users know that they aren’t suppose to be defragmented, but because Window has automatic defragmentation built in by default, how do you know if it is turned off on your SSD? Here’s a simple way:

 

1. Open Start Menu, type dfrgui.exe

2. Right-click it and select Run as Administrator

3. Select your SSD

4. Click Configure Schedule and make sure Run on Schedule is not checked

 

(If AHCI, Advance Host Controller Interface, mode was properly configured in your motherboard BIOS, Windows 7 should have detected your drive is SSD and disabled defragmentation, but, hey, it can’t hurt to check.)

For users of Win7, defrag never actually defrags a detected SSD drive.

 

Windows7 is SSD aware which disables SSD's from automatic defragment schedule

Anyone who is unsure their SSD has been detected properly and think it may still be scheduled for defragmentation can check here for confirmation. All programs >> Accessories >> System Tools >> Disk Defragmenter >> (if not enabled check "turn on schedule" temporarily..) >> then check Run on a schedule >> then select disks button: look under (Select all Disks) listed here you will find any disks not excluded for defrag or you can select the (Select all Disks) check box. If SSD's have been detected they will be excluded and removed from listing under (Select all Disks).

Just wanted to share some new information on SSDs and defragmentation. They positively should not be defragmented by a conventional defrag designed for a mechanical HD but it looks like someone has just unloaded a lot of R&D funds and discovered that SSDs do in fact benefit by a similar type of optimization. Here's the white paper:

SSD DEFRAG WHITE PAPER

 

I think, as SSDs become more widely used we'll find they have their own set of maintenance requirements.

at this time, SSD drives are very expen$ive....if you had one, you would probably know it. Some newer laptops are just starting to use ssd drives, but they are a premium priced laptops

Files may be moved into contiguous chunks on a SSD... If that's what Ron Caber was getting around to saying. Otherwise, SSDs don't suffer from performance degradation from fragmentation. But at issue, in order to prevent premature wear on the device, files must be placed evenly across the entire drive (wear-leveling).
