Check the manufacturer. Also if you check the manufacturer web site it specifically will say do not defrag.
It also will void the warranty.

Defrag causes excess wear. After defragging the SSD the SSD firmware will put the files right back where it wants them. So the files get moved twice.

No argument intended just pointing out the reason for not doing defrag. Good luck.
Your post got me to check the Plextor warranty and other information (128gb M3 Pro). The warranty is 5 years and there is nothing there or anywhere else about not defragging. So, would you mind documenting your claim for us?

Intel® High Performance Solid State Drive — SSD Frequently Asked Questions
Do I need to defragment my Intel® Mainstream Solid-State Drive (using Windows* Disk Defragmenter* or similar program)?
No. SSD devices, unlike traditional HDDs, see no performance benefit from traditional HDD defragmentation tools. Disable any automatic or scheduled defragmentation utilities for your Intel SSD. Using these tools simply adds unnecessary wear to the SSD.

Also in the owners manual. Warranty I have not found a specific as of yet.

If no mention is made of warranty issue at Plextor okay.

There has been increasing note in reviews and discussions like these that the quality of SSDs has improved over time and the initial stricture about wearing them out, such as by defragging, seems to have become less of an issue, if one at all. It's not my field, but that's what I keep seeing.

O&O is one of the top makers of after market defrag software.

Here is their input on the subject.>

Thanks for that link. It's getting harder to justify buying an optimizer - not that I have - when all the software can do with SSDs is use what's already there in Win 7 - TRIM.

I did not suggest buying anything.
O&O sells a defrag software and they are telling the would be users to not do so on SSD's.

After reading up on your Plextor besides TRIM it does have a "cleanup" of some sort in the firmware which some manufacturers call GC/garbage collection.
The system needs to sit idle for an hour plus for TRIM and "GC" to work.
Once a week or month or when it seems to be getting sluggish should be sufficient.
Should be no guarantee.

Good luck and enjoy your SSD.

Windows 7 Ultimate x64

My vote is that YES, there is a good reason to defrag a SSD drive. While many of the benefits it carries aren't applicable to the nature of SSDs, as you get no gain in speed, there is one benefit: file system recuperation.

Suppose you accidentally delete a file, and want to un-delete it. All programs work by reading the remaining directory entries, then guessing where it was stored on disk all remaining parts. A well known assumption is that the file will be contiguous on disk, and if it's actually not, parts of a recovered file might be corrupted or the file not recoverable or usable at all. By defraging your disk, you assure that the main recovery method remains valid.
Also, if a catastrophic system failure blows up some system areas of the filesystem, recovery software will have an easier time and greater success chance of a proper recover with a fully defragmented system.

Windows 7 Enterprise X64/Windows 10 Enterprise X64/Windows 10 Pro X64/Linux Mint

I own 5 SSDs from 3 different manufacturers. None recommend defragging SSDs. There is a reason Windows turns off defrag for SSDs. SSDs write data different than a spinning hard drive. Most, if not all, defragmenting programs are programmed for spinning hard drives and will look at an SSD and think it needs defraging when in fact it does not. Defreag will help a spinning hard drive by putting the data in fewer locations so it can be found easier. SSDs have no moving parts and therefore do not need defragging. Intel's tool box will turn off defrag, Windows will turn it off. There is a reason that happens.
