Traditional rotary hard drive

A traditional rotating hard drive is a basic non-volatile memory on a computer. That is to say, the information that closes it does not “disappear” when the system is shut down, which is different from the data stored in RAM. The hard drive is essentially a magnetically coated metal disc that stores your data, whether it’s a weather report from the last century, an HD copy of the original Star Wars trilogy, or your digital music collection. When the disc is rotated, the read/write head on the arm accesses the data. An SSD is functionally a hard drive, but the data is stored on an interconnected flash chip that retains data even when there is no power. The types of these flash chips are different from those used in USB thumb drives and are generally faster and more reliable. Therefore, SSDs are more expensive than USB thumb drives of the same capacity. However, like thumb drives, they are typically much smaller than HDDs, giving manufacturers greater flexibility in designing PCs. Although they can replace traditional 2.5-inch or 3.5-inch hard drive bays, they can also be installed in PCI Express expansion slots or even directly on the motherboard. This configuration is now available on high-end laptops and all MFPs. . (These SSDs mounted on the board use a form factor called M.2. The best M.2 solid state drive.)
