Samsung’s 128 TB-Class BM1743 Enterprise SSD Displayed at FMS 2024
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 larger 122.88 TB model of that SSD on current, alongside numerous recorded benchmarking programs. In contrast with the earlier interval, the BM1743 comes with a 4.1x enchancment in I/O effectivity, enchancment in knowledge retention, and a forty five% enchancment in vitality effectivity for sequential writes.
The 128 TB-class QLC SSD boasts of sequential be taught speeds of seven.5 GBps and write speeds of three GBps. Random reads might be present in at 1.6 M IOPS, whereas 16 KB random writes clock in at 45K IOPS. Based completely on the quoted random write entry granularity, evidently Samsung is utilizing a 16 KB indirection unit (IU) to optimize flash administration. That is very like the strategy adopted by Solidigm with IUs larger than 4K of their high-capacity SSDs.
A recorded benchmark session on the corporate’s PM9D3a 8-channel Gen 5 SSD was furthermore on current.
The SSD household is being promoted as a mainstream choice for datacenters, and boasts of sequential reads as quite a bit as 12 GBps and writes as quite a bit as 6.8 GBps. Random reads clock in at 2 M IOPS, and random writes at 400 Okay IOPS.
Accessible in numerous form-factors as quite a bit as 32 TB (M.2 tops out at 2 TB), the drive’s firmware contains non-compulsory assist for versatile knowledge placement (FDP) to assist maintain the write amplification facet.
The PM1753 is the present enterprise SSD flagship in Samsung’s lineup. With assist for 16 NAND channels and capacities as quite a bit as 32 TB, this U.2 / E3.S SSD has marketed sequential be taught 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 Okay IOPS.
Samsung claims a 1.7x effectivity enchancment and a 1.7x vitality effectivity enchancment over the earlier interval (PM1743), making this TLC SSD acceptable for AI servers.
The 9th Gen. V-NAND wafer was furthermore accessible for viewing, although footage was prohibited. Mass manufacturing of this flash reminiscence started in April 2024.
