You cannot do the same with an HDD because of its bulky size and shape. An SSD can be fixed in a PCI Express expansion slot or mounted directly on a motherboard. While HDD is bulkier, SDD is much smaller, allowing manufacturers more freedom to design their laptops or even desktops. If you place them side by side, the first thing that strikes is the difference in their sizes. While SSD uses flash memory, HDD uses a spinning platter with a magnetic coating.Īn HDD is a layer of disks, while an SSD entails interconnected flash memory chips. An SSD is relatively faster than HDD because of the way it accesses or stores data.

One way to ensure this is by replacing the traditional Hard Disk Drives (HDD) with the latest Sold State Drive. While being portable, a laptop must also work fast and smoothly.
