Intel Demos Samsung PM1743 PCIe Gen 5.0 SSD on Alder Lake Platform, Achieves Almost 14 Gb / s Bandwidth

Intel demonstrated Samsung’s recently unveiled PM1743 Gen 5.0 SSD on its Alder Lake desktop processor platform, showcasing the bandwidth improvements over a Gen 4.0 SSD.

The demo was presented by Intel Chief Performance Strategist Ryan Shrout, who had everything planned for a press unveiling at CES 2022, but since all the big companies pulled out and canceled their events there, switching to virtual conferences only. / keynotes, Ryan decided it was time to show off PCIe Gen 5.0 capabilities on his Twitter feed.

The demo includes an Intel Alder Lake Core i9-12900K processor that ran on an ASUS ROG Maximus Z690 APEX motherboard. The APEX comes with two PCIe Gen 5.0 (x16 and x8), electrical slots. While the GPU, an EVGA RTX 3080 FTW3, was installed in the first slot, the second slot featured an adapter card that allowed Ryan to populate the Samsung PM1743 SSD. The adapter is used to convert and adapt the enterprise level or any 2.5 “drive to the PCIe slot using an x4 interface.

Once the SSD is installed all that’s left is to see the performance and like most high-end PCIe Gen 4 SSDs, the one Ryan used to compare (WD SN850) ended up with throughputs of around 7000MB / s. This was a little less than 7000 because the drive had an OS loaded on it, but the Samsung PM1743 Gen 5 SSD ended up almost twice as fast with blazingly fast speeds that could read 14 000MB / s or 14Gb / s in the IOMeter test.

Ryan also mentions that he also tested two Samsung PM1743 SSDs, presumably in RAID0 mode, and hinted that they were “fast”. You can see the two PCIe Gen 5.0 SSDs working together and delivering up to 28.3 GB / s of throughput, which is literally crazy.

PCIe 5.0 offers a bandwidth of 32 Giga transfers per second (GT / s), doubling that of PCIe 4.0. Based on a proprietary controller designed to support the latest PCIe standard, the PM1743 will deliver exceptional read and write speeds to meet the rapidly increasing performance demands of data centers.

Samsung’s PM1743 will offer a sequential read speed of up to 13,000 megabytes per second (MB / s) and a random read speed of 2,500,000 input / output operations per second (IOPS), delivering 1 speeds. , 9 and 1.7 times faster than the previous PCIe. Products based on 4.0. In addition, write speeds have been dramatically increased, with sequential write speed of 6,600MB / s and random write speed of 250,000 IOPS, also offering speeds 1.7 and 1.9 times faster, respectively. These remarkable data transfer rates will provide enterprise server manufacturers deploying the PM1743 with a much higher level of performance.

Samsung is the first to offer SSDs that comply with the company’s PCIe Gen 5.0 standard, but we can expect more manufacturers to join the consumer / business movement later next year as the generation 5 will be more widely adopted by the next generation of AMD and Intel CPU platforms.
