O&O Defrag overview

What is O&O Defrag?

O&O Defrag is a cost-effective, simple and unique solution to increase throughput and accelerate performance, so that your systems and applications always run at optimal speed. It automatically adapts to each system to activate the appropriate performance regaining method. This boosts performance, reduces hardware strain and thus reduces hardware spending.

The Windows file system tends to break up writes into separate storage units and send each one to the storage layer separately. This results in small, fractured and random units of data spread around illogically on your machines. In turn this means every time you need to read, write or access data all these fractured units of a file need to be found and assembled.

By solving this problem at source, O&O Defrag boosts performance levels substantially, depending on the level of spliced data on the machine. It automatically reduces timeouts, slow starts and system crashes while at the same time increasing speed of data backups. Longer hardware duration & less investment in hardware going forward.

It can be installed on desktops, virtual machines and servers. New hardware is not necessary, simply maintain, streamline and optimize already-existing hardware.

Key benefits of using O&O Defrag

SOLID/Quick: This method, developed specifically for SSDs, performs a superficial optimization of the SSD, such as erasing the free space.

ClusterView with SSDs: In order to represent the degree of fragmentation of an SSD, the ClusterView now maps the logical structure of an SSD so that, accordingly, 6 blocks are combined into one.
