How OS X Manages Data
- HFS+ improves memory allocation scheme by preventing use of recently freed file space on your Mac hard drive. Alternatively, it searches for large portions of free space available on the drive and uses this space to store large files in contiguous memory locations. This helps to prevent fragmentation of the drive.
- OS X is equipped to combine various small allocations into one larger allocation on the drive. The process automatically defragments files and helps to minimize file system fragmentation.
- A technique known as ‘Hot File Adaptive Clustering’ keeps track of all your frequently-accessed and read-only files and places them to a special region on the drive called ‘Hot Zone’. The process involves defragmenting files during the transfer. Hot Zone, where your frequently-accessed files are placed, has the fastest access.
- OS X also defragments highly fragmented files on-the-fly that contain more than 8 fragments. These files are automatically defragmented when they are opened on your Mac machine.
With this optimized data management in Mac OS X, you can rest assured that your Mac is less likely to slow down to a crawl. However, as the drive fills up, same problems may appear.
