Samsung has quietly introduced its new BM1743 solid-state drive, designed for datacenter-grade read-intensive storage applications and offering a combination of capacity of up to 61.44TB and a relatively high performance enabled by a PCIe 4.0/5.0 x4 interfaces. In addition to its first 60TB-class SSD, Samsung also envisions 120TB-class drives using the same type of 3D V-NAND memory.

Samsung's BM1743 is based on the company's proprietary controller that supports both PCIe 4.0 and PCIe 5.0 x4 host interfaces as well as the company's 7th Generation V-NAND (3D NAND) QLC memory. From a performance point of view, the BM1743 offers a sustained sequential read speed of 7,200 MB/s as well as a sustained sequential write speed of 2,000 MB/s. As for random performance, Samsung specifies up to 1.6 million 4K random reads as well as up to 110,000 4K random writes, which is barely in line with the industry's best SSDs, but is good enough for its target applications.

Samsung's 61.44TB SSD is aimed at ultra-high-density read-intensive storage applications, such as AI inference on the edge or content delivery. To that end, their write endurance is 0.26 drive writes per day, which is logical as these drives will be rewritten very rarely, if ever.
