Why are SSDs better than HDDs?

HDDs are great for storage devices because they store data efficiently. However, SSDs can be faster than HDDs because they have less moving parts. They also have a much smaller form factor.

A flash memory based SSD uses memory chips that are capable of storing multiple bits of data per cell. SSDs are often referred to as solid-state drives because they don’t have any moving parts like traditional hard drives. An HDD has disks with magnetic platters that store data magnetically. When an HDD writes data to a disk, it flips the platters upside down.

These platters have tiny magnets on the surface that contain a specific polarity. To write data, the Hdd destroyer sends a current through the platters causing the magnetic fields to change.

When this happens, the polarity of the magnets changes. Once the write operation is finished, the HDD sends a current through the platters flipping them back over. As a result, the magnetism is changed and the data is stored. SSDs use flash memory cells instead of magnetic platters. Each cell stores a single bit of data.

Flash memory works similarly to a capacitor, with one side of the cell being positively charged and the other side being negatively charged. A voltage is sent across the capacitor and this voltage changes depending on whether the cell contains a 1 or a 0.
