i've used diskeeper, perfectdisk and o&o off and on for years, so i've had a great deal of experience with multiple versions of each.

o&o wins hands-down, in my book.

Thats becuase O&O does a much more thourgh job of defrag. Plus O&O will do a boot time defrag so that it can defrag system files that are normally locked out during defrag in windows. I havn't used perfectdisk but i have used a couple of verisons of diskeeper.

Tell me if WinXPs built in defrag utility uses diskeeper technology. Why are other companies still making defrag software? Because diskeeper just doesn't cut it.

O&O wins hands down.

and so does perfectdisk, which imo does the best job (performance-wise NOT length of defrag)

The answer to your question depends on what sort of performance you need. For normal Desktop it will be Perfect Disk.

On File Server, O&O may be better because it gives you the choice how to align those files in your perfer order. And that is the only strength i see with O&O.

Diskeeper is the best for Simple / Easy to use / Automated Defragment. This is good for lazy people / Noob who don't defrag the drive. The only down side is that it takes up another process sitting in your Task Manager.

PerfectDisk is best for Single Pass / and Performance. It align files in the best order for NTFS according to Microsoft. ( Who created NTFS ). On a normal Desktop, it makes no sense to align files in those 5 Methods provided by O&O.

With today computer and software usage. Hard Drive Get defraged too easily. That is why we are increasingly seeing Defragment Program doing its job in background.

And this is the answer to those who said Perfect Disk doesn't bring much performance. its because it get defrag too easily and you need to defrag again! ( I recommand once a week )

And that is the question i have always asked the O&O user, why are you using O&O ( apart from you like it ) any technical reason for it?

O&O is definately the extreme of defragmenting. arranging by date, name or usage. wow. this was my first defrag tool after windows one just made no sense at all. :rofl:

skipping versions should mean a good thing since that means 7 wasn't worth what you have to pay for 8 now.

i am currently using perfectdisk. You are right about simple, its fast does what it suppose to but not really getting in to it. offline defrag is the same as boot time defrag unless you use SATA. smart placement and just defrag doesn't make much diff.

diskeeper is really cool with the performance meter and improvement by 20% stuff. the stats on if your harddisk needs a defrag or not is clear too. Its really too fast to do much and if i remember right there is just one method.

Why is it not really getting into it? What has Offline defrag got anything to do SATA? And what do you mean by Smart placement doesn't make much difference.

It does alot of basic movement of files only. If you noticed after your defrag of a drive without running any other programs in background there are still fragments, even the frequently modified files remain where they were.

Offline defrag with SATA in my case it allows me to dismount the drive and defrag it immediately instead of rebooting and doing boot defrag. I know its not the main harddisk but i have 3 harddisk and its the only one that does that.

Smart placement is just slightly slower, thats seriously the only thing i noticed. Maybe i'm missing the big picture of it all but i tried it back to back on 2 drives and they looked like they files were sorted but it wasn't smart. hope that answer it for you.

I just tried O&O Defrag 8. OMG. Complete By Modified is still my favourite & once a week/2weeks will do cause this will take a while in my case. :yes:

    • For the purpose that it was built for, it’s a great machine. It’s okay to own multiple machines, it’s okay for machines to be different. If every computer was the same, they’d be boring af.
    • OpenAI is rolling out a major upgrade to ChatGPT memory by Pradeep Viswanathan OpenAI is rolling out a major upgrade to ChatGPT's memory, making the system more capable, current, and scalable across long-term use. Memory allows ChatGPT to remember useful details about users, including their preferences, projects, and constraints. Instead of starting every conversation from scratch, ChatGPT can use this context to provide more relevant responses in future chats. OpenAI first launched saved memories in February 2024. That feature allowed users to explicitly ask ChatGPT to save information into its memory, such as travel plans or writing preferences. However, this system had limits because it depended heavily on users giving clear instructions to remember something. Additionally, saved memories could become stale over time. In April 2025, OpenAI expanded memory by allowing ChatGPT to reference past chat context outside the saved memories list. This was powered by a background process called “dreaming,” which automatically curates memories from chat history. This made ChatGPT better at learning from natural conversation without requiring users to manually save every detail. Today, OpenAI announced a more capable and compute-efficient memory architecture built on top of dreaming. This new system improves ChatGPT’s ability to carry forward useful context, follow user preferences, and remain accurate as time passes. According to OpenAI’s internal evaluations, the new system improves factual recall from 67.9% in 2025 to 82.8% in 2026. Preference adherence improves from 55.3% to 71.3%, while accuracy over time improves from 52.2% to 75.1%. The best part of this new system is a new memory summary page where users can review ChatGPT's memories. Users can even update details, correct information, or give instructions on what topics ChatGPT should bring up and when. This new, improved memory system is available to ChatGPT Plus and Pro users in the US starting today. It will roll out to more countries, as well as Free and Go users, in the coming weeks.
    • I work for a video production company in Australia. The camera operators shoot footage and then pass the SD card over to the editors. Much easier than handing over the entire camera. Plus, on a busy day you can hand off the SD card and then pop another in for the next shoot. Or, you might have used multiple SD cards because you need the extra space for a long shoot. I also use USB cables and wifi for transferring footage, but in many cases an SD card reader is the easiest method.
