Oh the good old days of Diskeeper with its red (fragmented files/folders) and blue (contiguous (unfragmented) files/folders). It was the first proper defragger and it looked and worked great.
It worked so well that a stripped down version became the built-in defragger for Windows 2000 and XP. Nowadays it’s developed for enterprise only.
I purchased a PerfectDisk license when it was about v8. I found it OK but development was sporadic so I eventually moved over to O&O Defrag. I’ve been using O&O Defrag for about 20 years.
O&O Defrag isn’t free and at Christmas they used to do special bundles for a very low price. But they don’t seem to be doing this now. Some of their software has started moving to subscription, which means I’m out.
I do buy specialist software and it tends to be from specialist developers. I also look for very favourable upgrade pricing, or lifetime upgrade licenses, or ones where the developed timescale of releasing the new version is based on 2-4 years.
Recently, I purchased:
TeraByte Unlimited (BootIt Collection for $59.98!)
https://www.terabyteunlimited.com/bundle-info/
You get every peace of software they produce. Such as backup and restore, and partitioning and boot menu software. When you buy a product, you get each version as 4-for-1 (Windows, DOS, LINUX and UEFI). It’s amazing value for money and the software is specialised. Yet, once you have read the 270+ page PDF manuals you’ll know it inside out. Typically, they stay with a new version for 2+ years. And upgrading comes with a massive discount. For the price and terms of use, your data is worth it.
Hard Disk Sentinel Pro (Lifetime upgrades. I have the Family package of 5 licenses).
https://tinyurl.com/5cccvwfu
Again, this is niche software for storage device health monitoring. It will also test the surface too. It really is all you need for monitoring. While you are in trial-mode, you’ll be offered a 20% discount. The family package is $59 – 20%. For the price and terms of use, your data is worth it.
Process Lasso Pro ((Lifetime upgrades. I have the Family package of 5 licenses).
https://bitsum.com/get-lasso-pro/
Process Lasso PRO is very similar to having M$ SysInternal Process Explorer and Process Monitor all-in-one (AIO). It’s lifetime upgrade free, so what isn’t to like.
These are the defraggers, I’d recommend.

O&O Defrag 31
https://www.oo-software.com/en/products/oodefrag
I’m still on O&O Defrag v24 so this will give you a good idea that you don’t need to purchase an upgrade every time a new version comes out. It’s changed very little since 24. If you download a copy, sign up to their newsletter and get a $10 voucher against the price. It costs about $34 - $10 = $24. Not bad for something that won’t need to be upgraded for 5 years.
They say that there’s no benefit to defragging a SSD/NVMe because the delays in retrieving a file that wasn’t contiguous (unfragmented) was dependent on the time the heads took to locate the portions of a fragmented file. With SSD/NVEMe this isn’t an issue. Moreover, they say that defragging will increase wear and tear.
Are you saying that you’ve defragged your SSD/NVMe and its made a massive difference? It sounds as if that’s what you are saying.
O&O Defrag and others do have defragmentation for SSD/NVME’s so they obviously know something I don’t.
Except for O&O Defrag, all the other defraggers mentioned work in Safe Mode.
