You’re likely familiar with the concept of 3D, or three-dimensional, objects. Objects are two-dimensional when they can be described with two measurements, such as height and width. One-dimensional objects, for example, are made up of one measurement, similar to a line that connects point A to point B. You may even want to replace older 2D NAND technology with newer 3D NAND so that you can take advantage of its lower power consumption and faster speeds.The Difference in Dimensions: 3D, 4D, and 5DĪll of us are familiar with the various dimensions of objects and places we experience and interact with on a daily basis. In most cases, 3D NAND is the best option for your applications, even if you’re installing storage for personal use. When shopping for more storage space, you can choose between 2D and 3D NAND technology. The archive storage would still have a limited life span, but using it for simple archives would reduce writes to the number of times files are stored permanently until they’re needed for retrieval. A good way to recycle your storage devices is to move the 2D NAND device to archive storage. ![]() The 3D NAND technology is newer, but you might already use older 2D NAND technology and want to recycle it for use in other applications. Older devices that have 2D NAND technology can be upgraded to the latest 3D NAND technology. If you’re looking for a new SSD, a 3D NAND device will be cheaper per gigabyte of storage and provide you with terabytes of storage capacity. Newer servers might come with a 3D NAND storage device, but you can also buy them to install additional storage capacity in an existing server. For most applications, 3D NAND is the clear winner. It also has a longer life span and offers faster speeds. Using 3D NAND will lower costs and power consumption. 3D NAND also uses less power, so it causes less drain on an uninterrupted power supply (UPS) battery. Server manufacturers have limited space to install hardware, and 3D NAND allows them to provide more storage for their users at a lower cost and without the 2D NAND space requirements. All SSDs have a limited life span, but the additional cells provide more write cycles with a 3D NAND device compared to a 2D NAND device.įor servers with smaller chassis, 3D NAND devices are preferred because they’re smaller. For every write, an SSD loses a bit of its life span. SSDs have a limited life span, especially when they’re used in devices where several writes are performed. 2D NANDīecause a 3D NAND flash device contains several more storage cells than a 2D NAND device, users get more storage capacity with the newer technology. In addition, the newer 3D NAND technology reduces power consumption and increases the speed at which the device can write data to cells. By storing more cells within the drive’s chassis, 3D NAND provides more storage at faster speeds.Ī 3D NAND flash storage device also provides more storage at a lower price than a 2D NAND device. 3D NAND adds another layer and stacks cells vertically. 2D NAND devices place storage cells side by side. NAND flash storage technology uses cells stacked within the small chassis to give users a smaller storage component with better performance. 2D NAND: What’s the Difference?ģD NAND is the latest version of NAND technology, so it’s usually preferred over 2D. ![]() ![]() ![]() Depending on your goals, you can choose between the two technologies to build servers and backup devices. NAND flash memory is used for solid-state drive (SSD) technology to offer more reliable and faster storage in desktop computers and mobile devices. 2D NAND and 3D NAND are technologies used in desktop and mobile storage.
