Disk defrag is the process of reorganizing all the data on a hard drive so that it is contiguous, rather than scattered in hundreds of thousands of pieces around the drive. When files are disorganized, stored in fragmented pieces, the system cannot retrieve them as quickly.
The Windows operating system naturally creates file fragments every time a file is created, modified, or deleted.
The more places the hard drive head has to go to retrieve a file that is fragmented, the longer it will take to access that file. Accessing fragmented files substantially slows down PC speed and performance.
Every time the computer is used, fragmentation levels increase. Left unhandled, it will inevitably lead to PC slows, lags in performance, slow boot times, and eventually an inability to boot up at all. Waiting a week or even a day to defrag, means the PC is working harder and slower than it should be.
Slow boot up is a productivity drain; never mind the frustration it causes to IT and the users they support. Having applications and files stored contiguously is a key factor in keeping PCs stable and performing at peak efficiency.
The moment a file is fragmented and scattered across the disk drive (file fragmentation), it opens the door to a host of stability and reliability issues.
The most common problems caused by file fragmentation are slow boot times, inability to boot up at all, slow or aborted backups, file corruption and data loss, crashes and system hangs, memory problems, and hard drive failures.
Fragmentation is a major factor in slow boot times. While a system is booting up, there is a rush of data being transferred from the hard disk into the system memory to get the operating system ready for use. This initial burst of data during boot up is where fragmentation first becomes problematic.
Solid state drives (SSD) are generally considered to be faster, more powerful, more efficient and in some respects more reliable than hard drives. The problem is, they start out fast but gradually lose speed and, over time, become subject to failure. Most SSDs experience a dramatic and noticeable deterioration in performance. They also possess a limited number of erase–write cycles, which can result in a short lifespan with large amounts of write I/O.
SSDs require that old data be erased before new data is written over it, rather than just writing over the old information as is done with traditional hard drives. This doubles wear-and-tear and can cause major issues.
HyperFast® technology, included with Condusiv’s Diskeeper®, produces faster performance in solid state drives running on Microsoft operating systems. The HyperFast feature includes TRIM functionality and is enabled only if a solid-state drive is recognized.
If your organization’s AV (anti-virus) scans are running slower, the culprit is most likely disk fragmentation. Disk fragmentation has a severe impact on the speed and performance of anti-virus and anti-spyware scan speeds.
The basic principle is that the greater the degree of fragmentation, the worse PCs and laptops will perform. This holds true for anti-virus applications just as it would for any user interaction with a fragmented computer. With virus attacks still a serious issue in the workplace, the importance of efficient virus scans is critical.
If your systems are riddled with fragmentation, AV scans will take significantly longer to run, leaving your organization susceptible to new virus attacks as they emerge.
If defrag is not run regularly, PCs build up a significant level of fragmentation. This constant accumulation of fragmentation causes slow AV scans that get progressively slower over time.
IT professionals face the challenge of protecting critical business data. Yet there are substantial gaps in using conventional methodology of backup systems. Traditionally, the only way to recover a file has been from backup, a time-consuming chore that can only restore a file if it existed at the time of the last backup.
If the last snapshot was taken at 9am and the file had not yet been created, you’re out of luck. As you can see, this leaves a major hole in your data protection. But it doesn’t stop there. If a file is deleted or overwritten on a network drive, the Windows recycle bin will not catch it.
Accidental deletions and file overwrites happen all the time and they can cost your company a lot of time and money.
Why leave your organization vulnerable to data loss, when there is an easy solution that is specifically designed to provide true continuous data protection and instant, pain-free file recovery?
IntelliWrite® write I/O optimization technology prevents files from being fractured and broken apart into pieces, with each piece requiring its own I/O operation before being written to disk or SSD in a non-sequential manner. This stops the Windows phenomena of fragmentation from occurring before it becomes a problem.
IntelliMemory® read I/O optimization technology intelligently caches active data from read requests using idle server memory. This further reduces I/O overhead to the underlying storage device, enabling organizations to get more performance and life from the hardware they already have.
I/O Performance Monitoring 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 Diskeeper.
Analytics 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
Terabyte Volume Engine® Technology engineered to rapidly defragment volumes with hundreds of thousands of files.
Network Management Support ensures easy management of Diskeeper 16 settings and functionality across the network through the Diskeeper 16 Administrator edition or Group Policy.
InvisiTasking® intelligent monitoring technology allows all “background” operations within the system to run with near-zero resource impact on current activities.
Benefit Reporting dashboard displays the actual “time saved” benefit on every system so the value is easily quantifiable and never in question. It also shows fragments eliminated and what that means to percentage of write and read I/O reduction and how much I/O time was saved on that system due to writing and reading files in a sequential state as opposed to fragmented state. It also shows the percentage of all read traffic that is cached from idle DRAM and what that means to time saved by serving reads from DRAM instead of the underlying storage device. See displays for free spaces consolidated and total I/Os removed from both write and read optimization and total time saved for any given period of time.
Instant Defrag™ technology has been enhanced to monitor volumes to resolve critically fragmented files in real-time that are known to cause performance problems, making it SAN-friendly. This feature is turned off in the event of solid-state drives. This is the perfect complement to IntelliWrite in the rare instance that not all fragments were eliminated in the first place
Free Space Consolidation Engine swiftly consolidates free space and tightly integrates with Instant Defrag to handle new fragmentation as soon as it is created.
