Near the Spring Festival, Ziguang stores a new solid-state drive named p5160 on JD, which is positioned as a high-performance consumer grade nvme SSD.
P5160 uses the PCIe 3.0 X4 interface, and its performance is stronger than the previous P100: sequential read-write 3200 / 2200 MB / s, 4K random read-write 320K / 350K IOPs. Purple light storage provides it with 5-year or 150tbw (256gb model) / 300tbw (512gb model) warranty.
In addition to the performance parameters, Ziguang did not disclose the specific hardware composition of p5160, and the main control and flash memory types are temporarily unknown. Some media speculated that Ziguang might continue its cooperation with the group, and used the group ps5112-e12 master control scheme in p5160. However, after careful comparison of the ratio between the master size and DRAM cache, Xiaobian found that it was unlikely.
At present, it is known that only ps5112-e12s with metal heat dissipation layer is the main controller first exposed on CES 2020, and e12s optimizes the main control volume. The following figure is the e12s sample displayed on CES, which is quite different from the main controller used in purple light p5160 in proportion.
In addition to ps5112-e12s, Huirong sm2262 / sm2262en is more likely to be the only master controller used by Ziguang p5160. Of course, Ziguang storage chooses semi customized master controller. In terms of flash memory, Ziguang storage is labeled as the original chip particle of the original factory, but it is not clear which original factory it is. Changjiang storage, which belongs to the same group as violet storage, announced the mass production of 64 layer stacked 256gb 3D TLC flash memory in September last year. In addition, we did not find further details.
