That’s why laptops have gotten so much smaller and lighter in recent years.
It’s revolutionary in that for the first time, hard disk storage can now be lightning fast while fitting onto an even smaller device.
It’s almost like random access memory (RAM) that doesn’t delete itself when the device powers off. SSDs store memory in flash drive where it can be easily accessed. Solid-state drives (SSD), by comparison, do not have this problem. Files have to be sorted back together in an orderly fashion, not unlike an actual, physical filing cabinet. That’s why hard disk drives need to be “de-fragmented” or “de-fragged” from time to time. It just takes more time as the drive has to spin for a little while longer. HDDs can still access files that are not all written in one place. But as time goes on, and lots of files of varying sizes become written to the disk, they don’t all fit together nicely.
When large files are being written to a new drive, they fit nicely into the storage space. This occurs as a result of the disc becoming crowded with data that was not written on the drive sequentially. One of the most hassling problems of hard disk drives is that they tend to get “fragmented” with time. These drives are large, bulky, and prone to problems. The whole device kind of resembles a tiny, shiny vinyl record player. HDDs use a read/write arm on top of a spinning disc. Hard disk drives (HDD) are the original hard drives.
