Top FAQs about Diskeeper and new DymaxIO.

Can I still use the Diskeeper software I own?

Yes! The last release was Diskeeper 18. If you own Diskeeper 18, the Home and Pro editions will also run on Windows 11 and the Server editions will also run on Windows Server 2022.

Why did we stop selling Diskeeper?

Diskeeper is incredibly popular, having been licensed on tens of millions of Windows systems and countless testimonials and awards. With advancements in technology, it was time we made it easier for our customers to boost the performance and reliability of their Windows systems no matter the environment. We created DymaxIO to roll all our technologies from Diskeeper, SSDkeeper, and V-locity into one simplified and streamlined product. Now customers can receive the ideal performance optimization technologies automatically no matter the storage (HDD, SSD, SAN, all-flash, hyperconverged, or cloud) used.

Can I still buy Diskeeper?

No, we no longer sell Diskeeper. You can buy new DymaxIO for Windows PCs, Servers, and Hosts here.

How do I upgrade from Diskeeper to DymaxIO?

Once you have purchased new DymaxIO, simply uninstall Diskeeper, install DymaxIO, and apply the license key. The DymaxIO software download file and new license key will be available in your new online account.

Do you have a free trial?

Yes, we offer a 30-day free trial of new DymaxIO here. However, just like with Diskeeper, we provide an unconditional 30-day money- back guarantee when you buy DymaxIO.

Slide “Incredibly good software and so easy to install. After years of using Diskeeper Pro I am so glad I made this transition. In about a week of use, it has dramatically improved performance and stability already. And such a neat, compact footprint, unlike the bloatware we’ve gotten used to!” Gautam Patel Slide “DymaxIO is a carefully refined version of the already great Diskeeper and SSDKeeper applications. It is a unique tool on the software market that phenomenally improves the performance and extends the life of our computers. Obligatory!” Łukasz Staroszczyk Slide “Both my laptop and desktop PC (running Windows 10 Home and Pro) benefitted immediately from DymaxIO. They are both performing as if I’d added physical RAM or upgraded CPU’s. I haven’t yet run benchmarks, but the perceived improvements in performance are clear!” Per Hoel Slide “I also used Diskeeper for many years, at home and at work. DymaxIO is easy to install, then just forget it. My old computer runs well, considering it is an old HP about 10 years old. I changed the hard disk and installed an SSD drive. Everything runs smoothly, so no worries. I love it.” Lucas Noordink Slide “I’m a home user, long time with SSDkeeper, now DymaxIO, also a great tool for read write help for SSD, I asked support for a 2 user home price, and they give me very good price, nice support and very good software, thanks for making it possible.” Marcel Garcia

Deeper Performance Metrics

The DymaxIO I/O Performance dashboard tab takes a deeper look into the performance characteristics of I/O activity. The data shown here is similar in nature to other Windows performance monitoring utilities and provides a wealth of data on I/O traffic streams.

By default, the information displayed is from the time the product was installed. You can easily filter this down to a different time frame by clicking on the “Since Installation” picklist and choosing a different time frame such as Last 24 Hours, Last 7 Days, Last 30 Days, Last 60 Days, Last 90 Days, or Last 180 Days. The data displayed will automatically be updated to reflect the time frame selected.

The DymaxIO analytics graphs represent an hour-by-hour view into 13 key metrics.

The 2 Big I/O Inefficiencies Robbing Your Performance

Windows I/O Tax

The first is the caused by the behavior of the Windows file system. No matter where you run Windows and no matter what kind of storage environment you run Windows on, Windows still penalizes optimal performance due to severe write inefficiencies in the hand-off of data to storage.

Files are always broken down to be much smaller than they need to be. Each piece means a dedicated I/O operation to process the write or read, which causes an enormous amount of noisy, unnecessary I/O traffic that chews up precious IOPS, erodes throughput, and causes everything to run slower no matter how many IOPS are at your disposal.

30-40% of I/O traffic is nothing but mere noise, stealing resources and robbing optimal performance – no matter the Windows storage environment.

The I/O Blender Effect

The second is storage I/O contention, also known as the I/O Blender Effect, which happens when you have multiple systems all sharing the same storage resource.

As small, fractured I/O traffic from several virtual machines pass through the physical host hypervisor (Hyper-V or VMware), the hypervisor acts like a blender. It mixes these I/O streams, causing a randomization of storage I/O packets, before sending out a chaotic mess of small, fractured, and very random I/O streams to the storage controller.

It is essentially amplifying the Windows I/O tax multiple times causing even more performance penalty.

Your performance is penalized twice by these storage I/O inefficiencies causing systems to process workloads about 50% slower than they should.

Proactive, Cost-Saving Optimization

DymaxIO is “Set It and Forget It”® software. It installs (no reboot required) on Windows VMs or physical PCs/servers and performs optimizations inline, automatically while running transparently in the background with near-zero overhead.

Some people or organizations may react to performance challenges by throwing expensive new hardware at the problem. Overbuying and over-provisioning for more IOPS or data throughput might mask the underlying problem for a while, but it does not solve the root cause of performance issues.

The quickest, most inexpensive, and least disruptive approach to more performance is simply installing DymaxIO fast data software on all of your Windows systems and watching performance problems disappear.

DymaxIO Contains a Suite of Performance Technologies to Make Windows Systems Faster and More Reliable Whether Virtual, Physical, On-Premises, and/or in the Cloud.


IntelliWrite is a patented write optimization technology that automatically prevents excessively small, fractured, random writes and reads that harms performance due to the severe inefficiency in the native hand-off of data between the Windows OS and underlying storage. IntelliWrite write I/O optimization technology prevents excessively small, fractured I/O characteristics in real-time by providing file size intelligence to Windows to help it choose the best allocation at the logical disk layer when writing files. This intelligence ensures large, clean contiguous writes and subsequent reads in which maximum payload is carried with every I/O operation to and from the OS to underlying storage. Without IntelliWrite, the Windows OS just opts for the next available address at the logical disk layer, which is rarely, if ever, the right size. This inefficiency causes many more I/O operations to occur to/from underlying storage for any given file that should be optimally written and read with a single I/O operation. Since DymaxIO reduces the number of I/Os for any given workload, there are even fewer I/O operations being mixed and randomized at the hypervisor or SAN level, which combats the ill-effects of the “I/O blender” effect.


IntelliMemory is a patented read I/O optimization technology that intelligently caches hot read requests from server memory that is otherwise idle and unused. IntelliMemory is a server-side DRAM read caching engine that dynamically leverages idle, available DRAM to target I/O that penalizes storage performance the most—small, random I/O. IntelliMemory’s behavioral analytics engine makes the best use of DRAM for caching by collecting usage data and I/O characteristics across a wide range of data points. By servicing I/O at the top of the technology stack from the fastest storage media possible, organizations reduce latency and further reduce the amount of I/O having to travel to storage, complementing the I/O reduction benefits from IntelliWrite.


InvisiTasking is a patented intelligent scheduling technology that allows all the DymaxIO “background” operations within the server to run with zero resource impact on current production by only leveraging idle CPU cycles and memory. Should other processes demand those resources, InvisiTasking ensures they are released without latency so there is never an issue of resource contention.

Benefit Reporting

The “time saved” dashboard demonstrates the value by showing the amount of I/O traffic offloaded from storage, the percentage of read and write I/O traffic offloaded, and the resulting time saved to any one system or group of systems.

The main Dashboard tab shows “time saved” analytics such as Total I/Os Eliminated, Read I/Os Eliminated, Write I/Os Eliminated, Storage I/O Time Saved, Fragments Prevented and Eliminated, and Free Spaces Consolidated. The I/O Performance Monitoring tab reveals key performance metrics like IOPS, throughput and latency. It reveals the amount of workload processed on the local system for any given time period. It also provides important memory usage information like total physical memory and min/max/avg of available memory and how much of that was used for cache. This helps administrators fine tune memory allocations to get the most from the IntelliMemory DRAM caching engine. If there is not sufficient available DRAM, users are not getting the best performance possible from DymaxIO.

The Analytics tab provides an hour-by-hour view for any time period to understand exactly what is happening on the local system related to key metrics like workload, read/write percentage, IOPS, throughput, I/O response time and benefits like write I/O reduction from IntelliWrite and read I/O reduction from IntelliMemory.

Required Memory: 3GB of physical memory per VM or physical server

Recommended Memory for Optimum Caching: 4GB of available physical memory per VM or physical server

If running on MS-SQL: add up to 16GB of DRAM for blazing results, then cap SQL memory usage leaving the additional memory leftover for the OS and DymaxIO. If no additional memory is available, cap SQL memory usage leaving 8GB for the OS and DymaxIO.

Recommendation: Optimum results will not be achieved unless (1) systems have adequate memory and (2) the software is installed on each VM on the same host. Since each Windows VM generates a minimum of 30-40% unnecessary I/O traffic, it is imperative to install DymaxIO on all the VMs on the same host. If installing on 10+ servers, simply request the centralized management console by contacting sales to push the software out to as many servers as desired.

What DymaxIO Customers are Saying

“Typically, IT professionals respond to application performance issues by reactively buying more hardware. Without the luxury of a padded budget, we needed to find a way to improve performance on the hardware infrastructure we already have. It saved us from having to make a heavy investment in SSDs or do a complete rip and replace of our entire hardware infrastructure. To this day, I still can’t believe software is doing this.”
R. Ortiz, IT Manager, ASL Marketing

“I have used Diskeeper since it was first introduced. It has always worked well in keeping my drive defragged for the fastest response times for all of my apps. Thank you again for this fine piece of software.”
Philip Baldwin, NVQB

“The Undelete software that we use on all our Regional Servers is undoubtedly worth every penny. It
has saved our Techs numerous hours in restoring files inadvertently deleted as opposed to having to
restore from backup tape.”
Michael Lucas, Gancom (Division of Gannet Fleming)

“Undelete saves backup restores when someone accidentally deletes a file from a Windows share. We store tapes off site so Undelete can save a big delay for file restores of that type. Undelete does what it says on the box – really – and it works nicely as a network recycle bin.”
Glenn Edwards, Infrastructure Analyst, Itron

“I have been using Diskeeper for many years, it is installed as a routine on all servers, networked clients, SHO and any other computer. It has never presented any problem and has always demonstrated improved drive performance in both servers and clients. With each new release Condusiv does not merely provide “window dressing”, they actually improve the product with the objective of making it easier to use, more reliable, more effective and easier to use.”
