Computer Memory — Introduction and Types - DataLocker Inc.

The type of storage you use plays a crucial role in your organization’s efficiency and security. Computer memory is not only responsible for storing the data, but it also affects the transfer speed and efficiency by which your company can get work done With that in mind, let’s look at various types of storage and what they might mean for you. But first, let’s define computer memory.

What Is Computer Memory?

Computer memory is a system developed to read, write, store, and transfer data. Every system is built in a slightly different way, which results in differences in speed, durability, and efficiency. For instance, SSDs have memory chips, whereas HDDs feature a blend of various mechanical parts.

These storage devices interface with a computer’s operating system (OS) and allow the user to access data stored on them. An admin can store data, transfer it, and delete it according to their requirements. Besides construction, the security of data depends on the level of encryption in the drive.

Many users aren’t satisfied with simply storing data–they want to protect it as well.  Companies like Datalocker develop storage drives with military-grade AES 256-bit encryption to enhance security. Many of these encrypted drives meet  U.S. encryption standards to aid with various compliance needs.

Types of Computer Memory


HDD (Hard Disk Drive) is a storage type that features a blend of spinning disks and other hardware components. It allows a user to store and retrieve the data using a magnetic platter. With multiple parts, HDD delivers a decent read/write speed of up to 160Mbps.

Flash Memory

Flash memory is one of today’s most popular types of storage. It includes non-volatile memory chips that help in storing data and transferring it wherever required. Simply put, it’s electronic storage designed to erase and reprogram data electrically. USB thumb drives, and mp3 players, and some secure encrypted drives are some examples of flash storage.


When it comes to exploring types of computer memory, SSD might be the most efficient storage of all. A solid-state drive features a hierarchy of computer storage and stores data using flash memory. Unlike HDD, it delivers a read/write speed of above 1200Mbps and a bandwidth of 5000Mbps.


Computer memory works like a human brain in that it’s easy for a user to access the data they need when they need it. In general, people use various types of computer storage like HDD, flash memory, and SSD in daily life.

Of course, not all drives have built-in security, leaving them vulnerable to data breaches. If you’re looking for ways to secure personally identifiable information (PII), consider not just the type of memory your drive has, but the type of security. Secure encrypted drives from DataLocker are built with AES 256-bit encryption to keep out even the most determined cybercriminals.
