Nextorage’s upcoming PCIe Gen5 NVMe M.2 SSDs have been shown off and offer a significant improvement over existing Gen4 storage devices.
Nextorage’s PCIe Gen5 NVMe SSD delivers a 35% improvement in transfer rates versus a Gen4 SSD
Back in September, Nextorage showed off its PCIe Gen5 NVMe M.2 SSDs during the Tokyo Game Show. The manufacturer is based in Japan and offers its own solid state drives (SSDs) for consumer systems such as PCs and also the Sony PlayStation 5 console. Since consoles can only take advantage of Gen4 SSDs, their Gen5 SSDs are currently targeting PCs. Premium office only.
The Nextorage PCIe Gen 5.0 NVMe M.2 shown off during the event will use the standard M.2 form factor but will come in two options, a standard one with copper film or a high-end variant with a massive heatsink. We’ve seen manufacturers look to both active and passive cooling for Gen 5.0 SSDs and Nextorage seems to have opted for the latter. The heatsink shown has several fins extending from the motherboard and can take up a lot of space inside the computer. Nextorage is still in the process of evaluating the final heatsink design, so the look pictured at TGS may not be the final look.
In terms of specs, the Nextorage PCIe Gen 5.0 NVMe M.2 SSD features sequential read speeds of up to 10,000MB/s and write speeds of up to 9,500MB/s. The storage device will initially ship in 2TB and 1TB flavors. The 1TB variant will run at a slower 9500 read and 8500 write speed. 176-layer NAND flash is used which will explain why speeds haven’t already hit the 10GB/s+ mark as detailed here. For comparison, the Samsung 990 Pro, which is currently the fastest Gen4 SSD, has a read speed of 7450MB/s and a write speed of 6900MB/s. The Nextorage PCIe Gen5 NVMe SSD delivers up to 35% faster read and 48% faster write speeds, and that’s not even the fastest SSD using the Gen5 standard yet!
Shimizu I was able to visit Nextorage HQ where the company gave a brief demo of their upcoming product. We can see that the PCIe Gen5 NVMe SSD produced 10GB/s read speeds and 10GB/s write speeds. An interesting demo was done that showed the NAND Flash reached 59°C when the heatsink was primed but in an occasional run without the heatsink the temperatures immediately rose to 77°C and kept increasing.

This shows that NAND Flash can get really hot on Gen5 NVMe M.2 SSDs and will definitely require some good cooling solutions. This is why we’ve seen many motherboard makers use some additional forged M.2 heatsink designs on recent X670 and Z790 motherboards. Several SSD manufacturers are getting ready to launch their next-generation products by CES 2023, so stay tuned for more information.
