O&O Defrag Professional optimizes your hard disks and SSDs, and you can experience speed increases of up to 100%! Regular disk defragmentation optimizes your PC performance. When you defragment, the files that Windows splits up when saving documents across the hard disk or SSD are put back in order again so that files can be quickly recognized and found by the SSD or the read and write heads inside your HDD.

After entering my email to request a free license for “O&O Defrag Professional Giveaway: Lifetime Code Download,” nothing happens when I click on the “Request a free license” dialog box. I have tried this on two computers. This is the first time, using your site, that this has happened. What should I do?
Thank you.
O&O Defrag Pro is a good defragmenter. But if you want the gold standard for HDD defragmentation, then try PerfectDisk Business Professional.
It is the best defrag app I have ever used. Not free.
I’ve read on a number of sites that if you have an SSD drive, defragmentation is not recommended. https://www.howtogeek.com/855293/should-you-defrag-your-ssd/#:~:text=Defragmentation%20is%20not%20recommended%20for%20SSDs%20because%20it,these%20cycles%2C%20resulting%20in%20reduced%20performance%20over%20time
Defrag software was necessary in the late 90s and 00s, but with SSDs these days, they provide zero benefit.
If you have a HDD drive, you can get a cheap 120 GB SSD for 20 GBP.
This is purely snake oil.
Good share, WP. Thanks.
I am using it on my new Dell Inspiron 5457 as it comes with a HDD. Well, new to me. Actually, my friend gave it to me as she is upgrading to a Mac. Heck, it is only a couple of years old and has. 16 GB of RAM.
Now, what does it take for me to get my hands on Unhackme? This is the last piece of software that will make my ‘new’ laptop complete!
