Solidigm launched the first products D7-P5520 and D7-P5620 SSD
Intel actually sold its NAND-related business to SK Hynix a long time ago, at the end of 2021, the first phase of the merger-related to the business of the two companies will be launched. SK hynix established a subsidiary Solidigm to handle Intel’s NAND SSD-related business and took over the sales of Intel’s existing SSD products, now Solidigm has officially released its first products, the D7-P5520, and D7-P5620 for the enterprise market.
The D7-P5520 and D7-P5620 are optimized for today’s computing and storage server workloads, and are available in a variety of sizes and capacities, enabling better performance with less space and lower power consumption, and reduce operating costs.
The D7-P5520 is designed for read-intensive and light mixed workloads, with capacities ranging from 1.92TB to 15.36TB, available in U.2, E1.S, E1.L, and can achieve 1DWPD durability. The D7-P5620 is designed for mixed workloads, with capacities ranging from 1.6TB to 12.8TB. There is only one U.2 specification, which can achieve the durability of 3DWPD. Both products use 144-layer 3D TLC flash memory.
The sequential read and write performance of D7-P5620 SSD is 7100/4200 MB/s, the maximum 4K random read and write IOPS are 1,100,000 and 220,000 respectively, and the 4K read latency is 75us, and the write latency is 15us. Compared with the previous generation products, the random read performance is improved by 56%, the random write performance is improved by 53%, and the random mixed read and write performance of 70/30 is improved by 17%. Benefiting from the higher bandwidth PCI-E 4.0, the sequential read performance is directly doubled, and the sequential write speed has also increased by 20%.

Compared with DC P4510, the random read performance is improved by 57%, the random write performance is improved by 80%, the random mixed read and write performance of 70/30 is improved by 25%, the continuous read performance is increased by 123%, and the continuous write performance is improved by 25%. The speed increased by 37%.
At present, these two new SSDs are in mass production. According to Solidigm, ByteDance had already deployed servers using the D7-P5520 in March this year. The new SSD offers a wide range of capacity and performance improvements, increasing the TCO performance of its database and cloud software scheduled storage by 33%, and the D7-P5520 will also be used in ByteDance’s public cloud service platform Volcano Engine.
