Now the M.2 SSD of PCIe 3.0 channel will increase the read/write speed to 3000M/S. Do you think this is the upper limit of SSD?
Unis SSD will be again refreshes your perception of speed
The picture below is the latest exposure of the Unis SSD engineering sample with a capacity of 1TB.
It can be seen that the SSD of the M.2 interface uses the grouped master chip.
It can be seen that in the AS SSD Benchmark, the reading speed of this Unis SSD is over 4000M/S, and the writing speed exceeds 3700M/S. In CrystalDiskMark, the read speed exceeds 5000M/S and the write speed exceeds 4200M/S. However, this is only the running score of the engineering version. I don't know if the official version will be higher than this score.
From the Rank ， we can conclude that the SSD engineering version of Unis should be PCIe 4.0 interface, because 3.0 can't reach such a fast speed. Now the PCIe 3.0 flagship Samsung 970 EVO reading speed is only 3500M / S, which is far worse than the purple light. The PCIe 3.0 specification has a signal rate of 8 GT/s and the encoding mode is 128b/130b mode. Each lane supports 8*128/130=7.877Gbps=984.6MB/s, a PCIe 3.0 x16 channel, and x16 available bandwidth. It is 7.877*16=126.031Gbps=15.754GB/s, and the bidirectional bandwidth is up to 31.5GB/s.
PCIe 4.0 doubles this bandwidth. The larger the bandwidth, the more data that can be transmitted instantaneously. If this Unis SSD engineering version is PCIe 4.0, it is not surprising to run such a high score. There is also the use of the flagship level of the main control, the specific model or to wait for this purple SSD listed to know.
In fact, since the third quarter of 2018, AMD has discussed the PCIe 4.0 ecosystem with multiple storage vendors. Let us see the wireless possibilities of storage. The results of this Unis SSD have brought us surprises. It is expected that this SSD It will be officially listed in the near future.
