Samsung Unveils 256TB Data Center SSD with 3D QLC NAND Memory at Flash Memory Summit 2023

Samsung has demonstrated a data center SSD with a capacity of 256TB. The SSD uses 3D QLC NAND memory. However, the manufacturer does not share any concrete details about the drive in question.

Samsungs demonstrated its 256TB at the Flash Memory Summit in California. The drive uses Samsung’s 3D QLC NAND memory with four bits per cell, which enables a relatively high data density. Samsung already showed a 128TB SSD with qlc-nand during the Flash memory Summit last year.

The manufacturer says that the 256TB SSD consumes about seven times less power than eight separate 32TB SSDs, which together also account for 256TB. Samsung also shares few technical details about the SSD. It is also not known whether and when the SSD will actually become available to customers. If that happens, the SSD will mainly be intended for hyperscalers and data centers.

In addition to its 256TB SSD, Samsung also announced a PM9D3a SSD for data centers during FMS 2023. This series features a PCIe 5.0 interface and will be available in capacities from 3.84 to 30.72TB. Samsung reports that the SSD achieves sequential read speeds up to 2.3 times faster than the current PM9A3, which achieved sequential read speeds of 6.9GB/s. In theory, the new SSD would achieve speeds of around 16GB/s. The random write speeds are doubled according to Samsung. These SSDs will soon be available in different form factors. However, the manufacturer does not mention prices.
