Kioxia's second-generation 24Gbps SAS serial port SSD PM7 debuts: 112-layer stacked 3D TLC, sustained reading speed of 4200 MB/s

According to news from this site on January 29, Kioxia launched the industry's first solid-state drive "KIOXIA PM6" using a 24Gbps SAS serial port in 2020. The hard drive is built based on 24Gbps SAS technology and is supported by the PCIe4.0 ecosystem. It is known as The maximum continuous read speed is 4150 MB/s, and the maximum continuous write speed is 3700 MB/s.

Currently, KIOXIA is displaying the second-generation 24Gbps SAS serial solid-state drive KIOXIA PM7 at the Taipei International Computex in Taiwan, with a maximum capacity of 30.72TB.

It is reported that the hard drive is based on KIOXIA's "BiCS 5" fifth-generation fast storage technology,is built using 112 layers of 3D stacked TLC particles, with a maximum continuous read speed of 4200 MB/s and a maximum continuous write speed of 4,200 MB/s. The input speed is 4100 MB/s, and the performance is 20%ahead of the previous generation PM6.

It is reported that the 24Gbps SAS serial port number is specially designed for modern IT infrastructure and can "significantly improve Theoretical transfer rate of hard disk".

This site noticed that KIOXIA PM7 provides two industry versions to choose from. One is the "mixed-use" version PM7-V series, which provides 1.6/3.2/6.4/12.8 TB capacity options; the other One is the "intensive data reading and writing" version PM7-R series, which provides 1.92/3.84/7.68/15.36/30.72 TB capacity options,but the price has not been announced yet.
