Locates and removes different types of junk files that can be safely deleted. Detects and deletes junk files of all sorts, along with uninstalling unnecessary apps. Fill the remaining pages with the new data Combines cleaning, optimization, maintenance, and malware protection functionality within one app. It does not measure intelligence, aptitude, mental health, or values.Upon the first and every subsequent launch, you. First Launch: The app functions as a standalone app, and runs in its own window. It is the only disk utility app that you need on your Mac to keep it running at its very best. Rewrite the necessary pages into the freshly reset block Disk Aid will clean, optimize and protect your Mac, all whilst saving you up to several gigabytes of precious disk space. Disk Aid, has been built from the ground up and optimized for the very best performance and disk space saving ability.Reset every page in that block to blank.Record which pages in that block are still necessary.Find a block with enough pages marked "unused".Since an SSD can't directly overwrite an individual page, every time you want to write new data from that point on, the SSD needs to: However, as more and more data gets written, the blank pages run out, and you're left with random unused pages scattered throughout the blocks. When you write new data to the SSD, it can immediately write to those blank pages with blazing speeds. When you have a fresh SSD, it's loaded entirely with blocks full of blank pages. However, the consequence of how SSDs operate means that your SSD will become slower over time. Note that erasing a block doesn't necessarily mean the data is fully gone, but you can still securely delete data on an SSD. So then, how do SSDs handle data deletion? When enough pages in a block are marked as unused, the SSD commits the entire block's worth of data to memory, erases the entire block, then re-commits the data from memory back to the block while leaving the unused pages blank. They can only write data to empty pages in a block. SSDs can't directly overwrite data in individual pages. While cache and RAM operate at speeds in nanoseconds, a traditional hard disk drive operates at speeds in milliseconds. In HDDs, data can be written to any location on the plate at any time, and that means that data can be easily overwritten. The important thing to know is that theres a vast speed difference between the three. Why is this necessary to know? Because SSDs can only write to empty pages in a block. Pages are clumped together to form "blocks." Furthermore, SSDs are called "solid-state" because they have no moving parts. These grids are separated into sections called "pages," and these pages are where data is stored. Whereas SSDs use a grid of electrical cells to send and receive data quickly. Before the needle can read or write data, the plates have to spin around to the right location. If you took apart a typical HDD, you'd see a stack of magnetic plates with a reading needle-kind of like a vinyl record player. ![]()
