Samsung Debuts 61.44TB SSD, hints at a future 122.88TB Model

Samsung’s latest SSD innovation, the BM1743, introduces a massive 61.44TB storage offering while hinting at future advancements doubling this capacity.

Short Summary:

  • Introduces 61.44TB SSD using seventh-generation V-NAND technology.
  • Performance statistics indicate significant advancements in both read and write speeds.
  • Possible future model featuring 122.88TB capacity teased.

In the ever-evolving landscape of PC hardware, Samsung has once again laid down a significant marker with its newest SSD, the BM1743. This 61.44TB solid-state drive utilizes Samsung’s seventh-generation 3D NAND (V-NAND) technology. Highlighting this leap, the BM1743 incorporates 176 layers of memory cells, a notable upgrade from its predecessor, the BM1733, which boasted 96-layer technology at a maximum capacity of 32TB.

When it comes to performance, the BM1743 stands as a testament to the swift progression in data storage technology. With capabilities of up to 1.6 million random read IOPS and 110,000 random write IOPS, coupled with sequential read and write speeds of 7.2 GB/s and 2.0 GB/s respectively, this SSD is tailored for read-intensive workloads. Speaking on these advancements, an industry expert highlighted:

“Data storage evolution is critically important as both AI and HPC tasks continually push the boundaries of what is technically feasible. The BM1743 is a milestone in addressing these needs.”

The BM1743 represents double the sequential read and write speeds compared to Samsung’s fifth-generation technology, with random reads quadrupling in performance. This is a clear indicator that quad-level cell (QLC) SSDs are nearing the performance levels of their triple-level cell (TLC) counterparts while still providing greater storage density. This progress is essential for data-driven applications that demand both speed and capacity.

Design and Form Factors

Available in the traditional U.2 form factor, the BM1743 also presents an E3.S variant supporting PCIe Gen 5, thanks to a customized Samsung controller. This variety ensures that the SSD can meet diverse application requirements, whether in high-capacity data centers or advanced computational machines. Alongside these new capabilities are enhanced durability and data retention features. The endurance rating has been improved to 0.26 drive writes per day (DWPD) throughout its warranty period, up from the 0.18 DWPD of the BM1733. Additionally, the BM1743 extends its power-off data retention to three months, tripling the prior generation’s one-month duration.

Future Prospects

A tantalizing hint of a possible 122.88TB model promises even greater storage solutions to come. If realized, this future model would essentially double the existing capacity of the BM1743, signifying a monumental step forward in high-capacity SSD technology. This potential advancement is pivotal as more data-intensive AI and HPC applications emerge. Such high-density storage solutions are increasingly pertinent, as evidenced by the competition in this field, notably with Solidigm’s D5-P5336, which has led the high-capacity SSD market over the past year.

Samsung has long been a bellwether in the technology world, consistently pushing innovations in the semiconductor and storage domains. By improving both speed and capacity while maintaining reliability, the company continues to meet the escalating demands of various industry sectors, from AI to HPC tasks. During the announcement, Samsung stated:

“Our commitment to innovation is unwavering. With the BM1743 and its potential successor, we aim to address the ever-growing requirements of data-intensive applications, ensuring robust performance and reliability.”

Broader Industry Context

The broader landscape of technological advancements shows how storage solutions are adapting to emerging demands. For example, Western Digital’s recent introduction of its 64TB SSD and the Ultrastar DC SN861, the first enterprise-class PCIe Gen 5.0 SSD, reasserts the increasing focus on capacity and performance in storage technology. Similarly, AAEON’s release of the MAXER-2100 AI Inference Server underscores the ever-growing need for high-capacity and high-speed storage solutions to accommodate complex AI algorithms and massive data sets.

In line with these trends, the relentless march toward greater storage capacities is essential. Storage devices that can handle the mammoth requirements of modern AI and machine learning tasks are not just beneficial but essential. Samsung’s innovations are not merely technological achievements but responses to the palpable needs of an industry craving for more capable hardware to fuel the next generation of computing innovations.


Samsung’s unveiling of the BM1743 marks a significant milestone in PC hardware evolution. It not only meets the growing needs of today’s high-performance computing environments but also paves the way for the next phase of storage innovation. And as the horizon hints at a 122.88TB model, tech enthusiasts can only anticipate with excitement what comes next.

The tech landscape continues to evolve rapidly, and with companies like Samsung, Western Digital, and AAEON leading the charge, the future of high-capacity, high-performance storage solutions looks remarkably promising. As we draw closer to this future, the ability to store and retrieve vast amounts of data efficiently will be more crucial than ever, underpinning the ongoing advancements in AI, machine learning, and beyond.
