Nextorage demonstrates PCIe 5.0 SSD: Both sequential read and write speeds exceed 10000MB/s

Nextorage is a subsidiary of Sony, with SSD as its main product brand. It launched the NEM-PA series about a year ago, which is specially used for players to upgrade storage for PlayStation 5 consoles. At the 2022 Tokyo Game Show (TGS 2022) held in September this year, Nextorage showcased the new PCIe 5.0 SSD, demonstrating its determination to enter the enthusiast storage market in the next stage.

Recently, Shimizu, a well-known overclocking player in Japan, visited the Nextorage headquarters and saw a sample of PCIe 5.0 SSD. The official also conducted a simple test. According to Nextorage, this PCIe 5.0 SSD comes in 1TB and 2TB versions. The former has a sequential write speed of 9500MB/s and a sequential read speed of 8500MB/s, while the latter has a sequential write speed of 10000MB/s and a sequential read speed of 9500MB/s, using 176-layer NAND flash memory.

In the actual test, the PCIe 5.0 SSD sample should be a 2TB version, which uses the new generation PCIe 5.0 controller PS5026-E26 of Phison Electronics. Sequential read and write speeds both exceed 10,000MB/s, and the NAND flash memory temperature is 59°C if a heatsink is installed, and can soar to 77°C or above if run without a heatsink. Another reason for the temperature rise is that this PCIe 5.0 SSD sample does not enable energy-saving technology.

At the booth of the Tokyo Game Show in 2022, one of Nextorage’s PCIe 5.0 SSDs is also equipped with a huge heat sink, which occupies a large space. Shimizu said that it was in the form of an early version, and when it is actually released, it will bring a newly designed radiator, which will be much smaller in size. With the soaring heat generation of PCIe 5.0 SSDs, cooling devices are essential.
