From the Taipei Computer Show to the present, PCIe 4.0 is the masterSSDThere are no more than seven or eight hard drives, the most used of which is the clustered PCIe 4.0 master PSE5016-E16. The Group's PS5016-E16 is manufactured in 28nm process and supports the latest 96-layer 3D TLC/QLC flash memory. It has eight channels and a maximum capacity of 8TB. ​​It integrates the fourth-generation RAID ECC and LDPC error correction engine. It has an exclusive patented hardware accelerator design. The read and write speeds are up to 5GB/s and 4.4GB/s respectively.

However, PCIe 4.0 host and hard disk have not fully utilized the bandwidth of PCIe 4.0. In theory, the performance should reach 7GB/s. In order to achieve the full blood performance of PCIe 4.0 x4 bandwidth, and a new generation of PCIe 4.0 master, this matter has to be solved by the group.

Recently, the group company said that it will launch a new generation PCIe 4.0 master in Q1 next year, and the speed is expected to increase to 6500MB/s. This speed has almost doubled compared to the current PCIe 3.0 master hard drive, which is more than 30% faster than the current 5000MB/s PCIe 4.0 hard drive, which is almost approaching the limit of PCIe 4.0 x4 bandwidth.
