Samsung Unveils 61.44TB BM1743 SSD with Advanced 176-Layer QLC V-NAND Technology

Samsung has introduced the BM1743, a groundbreaking SSD with a colossal 61.44TB storage capacity, engineered with the cutting-edge 7th-generation QLC V-NAND technology. This SSD sets a new benchmark, incorporating 176 layers which significantly elevates bit density while reducing costs. The BM1743 will debut in a U.2 form factor while also offering an E3.S variant that supports PCIe Gen5 for amplified performance.

Key Takeaways

  • Samsung launches the BM1743 SSD, equipped with the latest 176-layer QLC V-NAND technology.
  • The BM1743 delivers remarkable sequential read speeds of up to 7200 MB/s and write speeds of up to 2000 MB/s.
  • Introducing an E3.S variant supporting PCIe Gen5 for heightened performance.
  • The BM1743 targets data centers, aiming to enhance efficiency and reduce costs, elevating cloud services and AI workloads.
  • Competitors like Western Digital are also venturing into the large-capacity SSD market with a 64TB SSD designed for AI applications.


Samsung’s foray into the high-capacity SSD market with the BM1743 leveraging the advanced 176-layer QLC V-NAND technology solidifies its position, presenting a formidable competition for rivals, particularly in data center environments. This breakthrough is poised to ignite a capacity race among industry players, notably impacting stock values and financial markets. In the short term, data centers stand to gain from cost reductions and performance enhancements, crucial for the efficiency of cloud and AI operations. Over the long term, this innovative release could potentially standardize higher storage capacities, reshaping industry standards and consumer expectations.

Did You Know?

  • 7th-generation QLC V-NAND technology:
    • QLC refers to Quad-Level Cell, a type of NAND flash memory that facilitates each cell to store four bits of data, effectively increasing storage capacity, albeit potentially compromising speed and endurance in comparison to SLC, MLC, or TLC.
    • V-NAND denotes Samsung's vertical NAND technology, a revolutionary method that vertically stacks memory cells to augment density and performance. The 7th generation signifies significant strides in this technology, likely enhancing efficiency, speed, and cost-effectiveness.
  • U.2 and E3.S form factors:
    • U.2, previously identified as SFF-8639, represents a form factor primarily employed in servers and workstations, supporting high-speed storage interfaces such as SATA and NVMe.
    • E3.S is a newer form factor tailored for high-performance computing settings, especially suitable for PCIe Gen5 SSDs, offering a smaller size and heightened thermal performance compared to traditional form factors like U.2.
  • DWPD (Drive Writes Per Day) metric:
    • DWPD measures how frequently the total capacity of an SSD can be written to each day over the warranty period. A higher DWPD signifies superior endurance and reliability, pivotal for data center applications where SSDs are extensively utilized.
