Computer management is a task that is much more difficult than using it to perform usual day-to-day operations, including both your personal and professional tasks. In fact, no matter which computer you own, you must be keeping it optimized in order to attain considerably high performance. You can use a commercial Mac speedup application to trash out the system waste accumulated internally on different spots of your Mac machine. Since fragmentation is one of the major factors responsible for gradual downfall in computers’ performance, an efficient defragmentation tool is the major requirement that you must fulfill without any failure.
Well, I hope you know the reason why I am recommending getting both speedup and defragmentation tools for your Mac Yosemite. In case you do not, let me brings some major cause of gradual performance downfall in Mac machines: overfilled volumes, disk corruption, file system issues, and fragmentation – the major one. In case you are eager to know how and why to optimize Mac Yosemite, go through the below section on this post carefully.
The space available for data storage on your Mac is raw, which you cannot utilize unless you format it as a Mac OS Extended (Journaled), i.e. the HFS+ file system. For this, you either use Disk Utility or choose any external commercial Mac partition manager. The Mac drive formatting includes splitting the storage space into blocks of distinct sizes. Later on, when you save a file on the Mac, the HFS+ file system stores it in a block based on mutual (i.e. both the file and the block) compatibility. Well, this is the ‘so-called’ intended block allocation scheme. However, the algorithm implemented for this often fails to do its job in an intended manner. Thus, a great number of blocks contain free spaces, as the size of every such file is smaller as compared to that of the block, and the left over space inside a block is termed the fragment.
Fragmentation: - The term ‘fragmentation’ refers to hard drive space being scattered because of the implementation of an inefficient algorithm for allocating blocks to save the files.
In addition to files like a Word document, PowerPoint presentation, and more, you must be storing large files (i.e. movies, videos, applications, and more) on the Mac. Since such large files cannot be stored in single blocks, Mac file system splits such files into multiple smaller segments, and then stores them in multiple blocks. In contrast, when you delete large files stored on the Mac, they free up multiple blocks. However, Mac file system does not reallocate recently emptied blocks to store new files, and therefore all these blocks remain unoccupied inside the occupied regions of the hard drive, and cause internal fragmentation.
When data produced because of execution of a program requests for space, the Mac file system fails to allocate blocks to store that data because the sizes of the available blocks do not match with that of the data. Well, the state of the hard drive becomes like free block are available, but outside the occupied regions. Utilizing such blocks leads to a state in which empty blocks occupy the filled blocks, and the empty blocks outside the filled regions of the hard drive cause external fragmentation.
Since storage blocks are allocated randomly due to implementation of an inefficient block allocation algorithm, the available blocks fail to store the allocated files because of their smaller sizes. Thus, the Mac file system splits all such files into segments, where the size of a segment is compatible with that of the blocks available. Well, storing individual files in multiple blocks causes scattering of data, which is referred to as data fragmentation.
Ultimately, the performance of a computer undergoes gradual downfall, which also affects its overall productivity indeed.
Defragmentation
The Mac file system is intelligent enough and it scans each file thoroughly for fragments when you open it. After scanning a file, if it is found as highly fragmented (i.e. having more than eight fragments), the Mac file system defrags it automatically. This makes Yosemite users believe that Mac machines do not come across fragmentation. However, the files Mac file system scans and defrags automatically are below 25MB of size, which means that there is no auto defragmentation scheme for large files. Since not each file is that much small (i.e. file size < 25MB) to be eligible for automatic defragmentation, you must have a commercial defragmentation application to optimize your Mac performance.
Firstly, the defragmentation application analyzes the hard drive thoroughly in order to have an updated report containing complete information of filled blocks, blocks allocation algorithm, the unallocated blocks, and other required information. Defragmentation involves reorganizing the physical blocks of the hard drive logically to improve the performance of the Mac machine, thereby minimizing the number of fragments. Though defragmentation is quite a long process, it actually results in improved performance of the Mac systems. Besides, the process also implements compaction that impedes fragmentation (i.e. builds larger regions of free spaces on the hard drives) to occur again.
Now, I guess you know how and why to optimize Mac with a defragmentation app.
Final conclusion: - While choosing a commercial defragmentation application for the Mac Yosemite, you find a number of similar apps on the Internet. In such a state, you may get confused and pick one randomly. Thus, I recommend choosing one carefully, as selecting an inefficient defragmentation app may cause data loss on your Mac. In case you are confused or unaware of which defragmentation software to choose, I recommend you to use Stellar Defrag Drive. It is one of the highly popular software which is used by thousands of users worldwide.
