Samsung had quietly launched its BM1743 enterprise QLC SSD final month with a hefty 61.44 TB SKU. At FMS 2024, the corporate had the even bigger 122.88 TB model of that SSD on show, alongside a number of recorded benchmarking periods. In comparison with the earlier technology, the BM1743 comes with a 4.1x enchancment in I/O efficiency, enchancment in knowledge retention, and a forty five% enchancment in energy effectivity for sequential writes.
The 128 TB-class QLC SSD boasts of sequential learn speeds of seven.5 GBps and write speeds of three GBps. Random reads are available in at 1.6 M IOPS, whereas 16 KB random writes clock in at 45K IOPS. Primarily based on the quoted random write entry granularity, it seems that Samsung is utilizing a 16 KB indirection unit (IU) to optimize flash administration. That is much like the technique adopted by Solidigm with IUs bigger than 4K of their high-capacity SSDs.
A recorded benchmark session on the corporate’s PM9D3a 8-channel Gen 5 SSD was additionally on show.
The SSD household is being promoted as a mainstream choice for datacenters, and boasts of sequential reads as much as 12 GBps and writes as much as 6.8 GBps. Random reads clock in at 2 M IOPS, and random writes at 400 Ok IOPS.
Out there in a number of form-factors as much as 32 TB (M.2 tops out at 2 TB), the drive’s firmware consists of optionally available help for versatile knowledge placement (FDP) to assist tackle the write amplification facet.
The PM1753 is the present enterprise SSD flagship in Samsung’s lineup. With help for 16 NAND channels and capacities as much as 32 TB, this U.2 / E3.S SSD has marketed sequential learn and write speeds of 14.8 GBps and 11 GBps respectively. Random reads and writes for 4 KB accesses are listed at 3.4 M and 600 Ok IOPS.
Samsung claims a 1.7x efficiency enchancment and a 1.7x energy effectivity enchancment over the earlier technology (PM1743), making this TLC SSD appropriate for AI servers.
The 9th Gen. V-NAND wafer was additionally obtainable for viewing, although images was prohibited. Mass manufacturing of this flash reminiscence started in April 2024.
