Chinese manufacturer UNIS creates ultra-fast 14.9 GB/s S5-series PCIe 5.0 SSD

UNIS’ upcoming S5 SSD lineup promises high-end PCIe 5.0 performance

UNIS, a Chinese manufacturer, has revealed two new ultra-fast PCIe 5.0 SSDs, both of which break past the 14 GB/s barrier. Based on their revealed specifications (via mydrivers), these UNIS S5-series drives should stand amongst the fastest SSDs on the market.

With their standard S5, UNIS boasts sequential read speeds as high as 14.9 GB/s and drive capacities of 1 TB and 2 TB. This drive lacks DRAM cache, placing it behind higher-end SSD models. Note that the S5 uses a 12nm SSD controller, which will likely make it a hitter-running SSD than the S5 Ultra.

UNIS’ S5 Ultra stands above the S5 with its 6nm controller and included DRAM cache. This drive promises higher capacities with only 2TB and 4TB models. It also promises sequential read/write speeds of 14.2 GB/s and 13.4 GB/s, respectively. This model is optimised for high productivity scenarios, like content creation and workstation use. Here, the drive’s DRAM cache will prove highly beneficial.

Both drives are M.2 2280-sized SSDs. Due to its 12nm controller chip, we expect the lower-end S5 SSD to run hotter than its Ultra-series counterpart. Both SSDs have a passive 1mm graphine passive heatsink. However, it is likely that both drives would benefit from a larger attached heatsink.
