Why does SSD storage load much faster than HDD storage?
In: Technology
On a HDD, the data is stored on a bunch of magnetic platters like tiny vinyl records, and so, to read or write data, the HDD has to physically swing a tiny arm out to the right physical location on the disk.
When dealing with a lot of small files, a HDD has to move those tiny arms around a lot because while the data itself is spread across the surface of the disk, a lot of the basic file information is contained in a sort of reference table all the way at the beginning of the disk.
On an SSD, the data is stored directly in electric circuits. There are no moving parts, so reading/writing data happens instantaneously.
