Samsung announced several solid-state drives at The Future of Memory and Storage conference (formerly Flash Memory Summit): the new PM1753 line promises record PCIe 5.0 speeds, and the BM1743 will soon receive a 128 TB model. The PM9E1 with PCIe 5.0 will soon debut in the consumer segment.

The top speeds in Samsung’s existing range are the PM1743 series, but it’s been around for a few years now and it’s time for its successor to come out. The new Samsung PM1753 also connects via PCIe 5.0 x4, but almost completely uses the potential of the interface. If the PM1743 has a sequential read speed of up to 14 GB/s, then the PM1753 has 14.8 GB/s, and the write speed has increased from 6 to 11 GB/s. Random operations performance increased to 3.4 million IOPS. The new generation drive is equipped with a 16-channel controller, TLC-NAND memory with a capacity of up to 32 TB and is offered in U.2 and E3.S form factors.
Samsung showed its first SSD with a capacity of 128 TB seven years ago, and since then it has been wandering around exhibitions as a demo. A model of this capacity will hit the market in the BM1743 series. In the spring, the Korean manufacturer updated the series with a 64 TB (61.44 TB) model and said that this figure could double – now the company has officially announced the BM1743 SSD with a capacity of 128 TB (122.88 TB), but has not yet announced its release date. The drive is equipped with QLC memory from Samsung and offers read speeds of 7.5 GB/s, write speeds of 3.5 GB/s and up to 1.6 million IOPS for random operations.
The company again decided to look into the future. An SSD with a capacity of 256 TB will appear between 2024 and 2026, a 1 PB model can hardly be expected until 2035, and Samsung will release an M.2 SSD with a capacity of 16 TB only in 2027. The Korean manufacturer also talked about the PM9E1 model for consumer systems – it will appear as an OEM product with PCIe 5.0, capacity up to 4 TB and offer speeds of 14.5 GB/s read and 13 GB/s write.
