It is more common than the SSD in most homes and offices, but that may be changing as new storage advancements are made. SSD stands for solid-state drives, which are storage devices that use flash memory rather than spinning disks. They store data in blocks and pages, but they do not have any moving parts, making them more durable and requiring less power.
They also do not generate as much heat or noise since they have no moving parts inside, making them perfect for laptops. However, they do have some disadvantages. SSDs use flash memory, which is a type of non-volatile storage. What this means is that it does not require power to store information. Unlike an HDD, where bits are written randomly throughout its storage space, an SSD organizes data in blocks and erases these blocks before writing over them. With every generation of flash memory technology comes a reduction in cell size and increase in capacity—and this means that modern-day SSDs have more space for writing data than ever before.
SSDs offer many advantages over HDDs, including lower power consumption, higher reliability and performance levels, better shock resistance, faster access to stored data, and less heat output.
The price of SSDs is one disadvantage. The disc spins, allowing the read-write arm to read data on the disc or write data to it as it passes. The faster the platter spins, the faster the hard drive works, which can impact how quickly your operating system responds, and how long it takes applications installed on the drive to load and open. As the name suggests, an SSD — unlike a traditional hard drive — has no moving parts.
Instead, it uses NAND flash memory. These drives slot into the PCIe lane of a motherboard, enabling much faster speeds. However, if you have a smaller motherboard, or you use your PCIe lanes for other devices, such as graphics cards or sound cards, then you may not want an SSD taking up a lane.
Another increasingly common connection for SSDs is the M. Compare Crucial solid state drives. Hard drives use magnetically sensitive platters which are moved by a motor, whereas an SSD uses flash memory without any moving parts, meaning they are faster.
The difference between hard drives and solid state drives is in the technology used to store and retrieve data. The table below illustrates some of the differences. HDDs are cheaper and you can get more storage space. SSDs, however, are incredibly faster, lighter, more durable, and they use less energy. Your needs will dictate which storage drive will work best for you. Find a product Part no. Your search did not match any active Crucial part numbers or configuration IDs.

Legacy Intel materials will be provided until the transition is complete. Learn about the differences between HDDs and SSDs, the form factors available, how they compare in capacity, speed, power, and more. The type of storage your computer uses matters for performance, including power usage and reliability.
Here's a quick guide on the best use for each and how to compare. An HDD is a data storage device that lives inside the computer. It has spinning disks inside where data is stored magnetically. The HDD has an arm with several "heads" transducers that read and write data on the disk. It is similar to how a turntable record player works, with an LP record hard disk and a needle on an arm transducers. The arm moves the heads across the surface of the disk to access different data.
In general, they are lower in cost and are practical for data that does not need to be accessed frequently, such as backups of photos, videos or business files. They are available in two common form factors: 2. SSDs got their name—solid state—because they use solidstate devices under the hood. In an SSD, all data is stored in integrated circuits. This difference from HDDs has a lot of implications, especially in size and performance.
Their capacity—or how much data they can hold—varies, making them flexible for smaller devices, such as slim laptops, convertibles, or 2 in 1s.
