Without much fanfare, Samsung introduced the BM1743, one of the world’s most capacious 61.44TB solid-state drives designed for data centers, and announced plans for a 122.88TB SSD.

The new Samsung BM1743 drive is based on the company’s proprietary controller and uses seventh-generation 3D V-NAND QLC memory. The device supports both PCIe 4.0 and PCIe 5.0 x4 interfaces, providing high performance. According to Tom’s Hardware, this SSD is capable of reaching sequential read speeds of up to 7,200MB/s and sequential write speeds of up to 2,000MB/s.

In terms of performance, the BM1743 can perform up to 1.6 million random 4K reads per second and up to 110,000 random 4K writes per second. Although these indicators are not record-breaking, they are fully consistent with the intended use of the device.

The BM1743 drives are planned to be available in U.2 form factors for hosts with a PCIe 4.0 x4 interface, and in the E3.S form factor with a PCIe 5.0 x4 interface. The company has not yet disclosed data on the power consumption of the new SSD, which could be quite high due to the device’s massive capacity. However, considering that storage density is a key characteristic of a drive, power consumption may not be the most important indicator.

Note that the Samsung BM1743 currently has very few competitors on the market. Only Solidigm and Western Digital offer a 61.44TB SSD with a PCIe interface. Other manufacturers such as Kioxia, Micron, and SK hynix have yet to release drives with this capacity.

The new SSD is designed for ultra-high storage density applications like AI or edge computing for content delivery. Interestingly, Samsung isn’t stopping there, and is already talking about plans to create 122.88TB capacity drives using the same type of 3D V-NAND memory.
