A hard disk drive (HDD) is an internal or external computer component that stores data, such as the operating system, applications, and user files. HDDs are “non-volatile” storage devices, meaning they retain stored data even when power isn't being supplied.

There are advantages and disadvantages to each type of drive, and deciding on which type is right for you comes down to how you use your computer. Our guide to HDD vs. SSD shows you how each type of storage drive works and what it means for you.
An SSD or HDD serves as your computer's long-term memory, storing and remembering files even when your device is off. It works alongside your system's memory (RAM) and processor to access and use data, including things like your operating system, programs, documents, games, images, and music.
SDRAM synchronizes with the system's clock speed, allowing for more efficient data transfers. This synchronization enables a steady flow of data, reducing delays in accessing information. Various types of SDRAM, such as double data rate (DDR) SDRAM, have evolved to provide increased data transfer rates.
TRIM is a command for the ATA interface. As you use your drive, changing and deleting information, the SSD needs to make sure that invalid information is deleted and that space is available for new information to be written. Trim tells your SSD which pieces of data can be erased.
On the other hand, M.2 NVMe SSDs leverage the PCIe (Peripheral Component Interconnect Express) interface, designed specifically for solid-state storage. PCIe offers significantly higher data transfer speeds compared to SATA, allowing NVMe SSDs to achieve much faster performance.
S.M.A.R.T. and SSDs. S.M.A.R.T, or SMART, stands for Self-Monitoring, Analysis, and Reporting Technology. SMART is a monitoring system for storage drives that gathers data on the health of the drive and reports it to the user. SMART is useful for ensuring that your drive is performing at its peak.
All desktops, laptops and tablets use random-access memory (RAM) to store the short-term data they need to function. As computers evolve, RAM improves too. Computers built before 2002 generally used synchronous dynamic random-access memory (SDRAM).
Computer random access memory (RAM) is one of the most important components in determining your system’s performance. RAM gives applications a place to store and access data on a short-term basis. It stores the information your computer is actively using so that it can be accessed quickly.
