  • Optimized for massive data volumes
  • Improved total bytes written (TBW) ratings of up to 2,400TB
  • Blazing-fast speeds and ultimate power efficiency

Samsung Electronics has announced the release of a new 4-terabyte (TB) offering in its SSD 990 PRO series. The 990 PRO series is a lineup of high-performance PCIe 4.0 SSDs powered by Samsung’s eighth-generation V-NAND technology and enhanced proprietary controller.

The 990 PRO series is optimized for massive data volumes, making it ideal for tasks such as 3D/4K graphics work, data analytics, and high-quality games. It offers blazing-fast speeds and ultimate power efficiency, making it suitable for PCs, Laptops, game consoles, and computing systems.

With improved total bytes written (TBW) ratings of up to 2,400TB, the 990 PRO series ensures increased SSD reliability and longevity. This makes it perfect for those with highly demanding workloads and large storage capacity needs.

The 4TB 990 PRO offers near-max performance in a PCIe 4.0 interface, with sequential read speeds of up to 7,450 megabytes-per-second (MB/s) and write speeds of up to 6,900MB/s. It also delivers boosted random read and write speeds of up to 1,600K and 1,550K IOPS respectively.

The 990 PRO series achieves breakthrough power efficiency, with up to a 50% performance improvement compared to the previous 980 PRO series. It incorporates a nickel coating on the controller and features a heat spreader label on the back side of the SSD to ensure optimal temperature level maintenance and minimal performance fluctuations over time.

Thanks to Samsung’s high-density NAND and memory stacking technology, the 4TB 990 PRO is designed with a single-sided M.2 form factor, making it slimmer than other double-sided M.2 SSDs. This allows for easy installation in ultra-thin laptops without the risk of damaging other components.

The Samsung Magician software ensures optimal performance in SSDs by keeping firmware, drivers, and other settings up to date. It also offers customization options for power and performance optimization. The software supports RGB functionality for the 990 PRO with Heatsink, allowing gamers to customize color and LED effects.

The 4TB capacity models of the 990 PRO and 990 PRO with Heatsink will be available in early October 2023. The 990 PRO series’ 1TB and 2TB models are currently available for purchase. For more information, including warranty details, visit or

Technology Explained

M.2: M.2, also known as Next Generation Form Factor (NGFF), is a computer expansion card format that is designed to replace the outdated mSATA standard. It is thinner and longer than mSATA, which gives it a much higher data transfer rate. The M.2 format measures 22mm in width and can measure up to 110mm in length. It uses the M-key and B-key connectors to interface with PC host systems, and can connect to both SATA III and PCIe for data transfer. Due to its small size, M.2 is often used for ultra-slim laptops and netbooks, as well as in embedded SSDs for tablets and other mobile devices. It is also becoming increasingly popular in the desktop computer industry, thanks to its compactness and fast transfer speeds. This makes M.2 ideal for gaming PCs, workstations, and other demanding applications that require high levels of data throughput.

NAND: NAND technology is a type of non-volatile memory that is used in many computer applications. It is a type of flash memory that is used to store data in a non-volatile manner, meaning that the data is not lost when the power is turned off. NAND technology is used in many computer applications, such as solid-state drives, USB flash drives, digital cameras, and memory cards. It is also used in many embedded systems, such as cell phones, tablets, and other consumer electronics. NAND technology is a reliable and cost-effective way to store data, making it a popular choice for many computer applications.

PCIe: PCIe (Peripheral Component Interconnect Express) is a high-speed serial computer expansion bus standard for connecting components such as graphics cards, sound cards, and network cards to a motherboard. It is the most widely used interface in the computer industry today, and is used in both desktop and laptop computers. PCIe is capable of providing up to 16 times the bandwidth of the older PCI standard, allowing for faster data transfer speeds and improved performance. It is also used in a variety of other applications, such as storage, networking, and communications. PCIe is an essential component of modern computing, and its applications are only expected to grow in the future.

SSD: A Solid State Drive (SSD) is a modern data storage device that employs flash memory technology to store data electronically. Unlike traditional hard disk drives (HDDs), SSDs have no moving parts, resulting in significantly faster read and write speeds. This leads to quicker boot times, faster application loading, and smoother overall system performance. SSDs are known for their durability, shock resistance, and energy efficiency, making them ideal for laptops, ultrabooks, and other portable devices. They come in various form factors, including 2.5-inch, M.2, and PCIe cards, and are favored for their reliability, quiet operation, and reduced heat generation
