Samsung introduces 4TB Model for 990 Pro SSD, Expanding Storage Capacity


August 25, 2023 by our News Team

Samsung has announced the launch of its 4 TB 990 Pro SSD, offering impressive performance and reliability for gaming, video editing, and 3D work, with two versions available featuring either a graphene heat spreader or an aluminum heatsink.

  • Offers impressive sequential read and write speeds of up to 7,450 MB/s and 6,900 MB/s respectively.
  • Achieves impressive random operation speeds, with 1,400,000 IOPS for reads and 1,550,000 IOPS for writes.
  • Comes with a five-year limited warranty and an endurance rating of 2400 terabytes written (TBW).


Samsung is set to address a notable omission in its SSD lineup by launching a 4 TB version of its popular 990 Pro family. The announcement was made on Twitter, with Samsung acknowledging the demand for a higher-capacity option and promising to deliver. The 4 TB 990 PRO is expected to offer the same impressive performance as its predecessors, making it ideal for gaming, video editing, and 3D work.

In terms of speed, the 4 TB drive boasts impressive sequential read and write speeds of up to 7,450 MB/s and 6,900 MB/s respectively. It also achieves impressive random operation speeds, with 1,400,000 IOPS for reads and 1,550,000 IOPS for writes. These performance figures put it on par with other flagship SSDs on the market.

While the 4 TB version may not be a must-have for owners of the latest AMD Ryzen or Intel Core processors, which support PCIe 4.0 x4 interfaces, it presents an attractive option for those looking to upgrade their PCs with M.2 slots featuring a PCIe 4.0 interface. Additionally, the current affordability of 3D TLC NAND makes a 4 TB SSD a compelling choice.

Samsung plans to offer two versions of the 990 Pro 4 TB SSD: one with a graphene heat spreader for compatibility with Laptops, and another with a larger aluminum heatsink for consistent performance during heavy workloads. The pricing details have not been officially disclosed, but it is expected to be in line with market realities. The drive comes with a five-year limited warranty and an endurance rating of 2400 terabytes written (TBW), ensuring its longevity and reliability.

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also known as Next Generation Form Factor (NGFF), is a computer expansion card format that is designed to replace the outdated mSATA standard.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.


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
