130TB Kioxia solid-state drive "goes to heaven" for storage expansion on the International Space Station

According to news from this site on February 1, Kioxia recently announced that its multiple solid-state drives totaling 130TB were launched on January 31, Beijing time, on the "Cygnus" cargo spacecraft. will be used to expand international Space station storage capacity.

These Kioxia SSD products are part of HPE’s Spaceborne Computer-2 spaceborne computer project, which aims to provide a local edge to the International Space Station using existing commercial technology. Computing power, without the need to transmit all data to ground computers for calculation, can enhance the computing power autonomy of the International Space Station.

Kioxia said that the solid-state drives that will be installed on the International Space Station include four 960GB RM series Value SAS solid-state drives, eight 1024GB XG series NVMe solid-state drives, and four 30.72TB PM series enterprise-class SAS drives. Solid state drive, totaling 130TB (Note from this site: According to the 1TB=1000GB given by the Kioxia official website, the actual total is 134.912TB).

Kioxia believes that flash memory-based solid-state drives are more suitable than traditional mechanical hard drives to withstand the performance and reliability requirements in the outer space environment: Solid-state drives have no moving parts, are not easily affected by electromagnetic waves, and can Provides faster performance.

Throughout the mission, Kioxia will monitor the health of the SSD on a daily basis and transfer log files from the International Space Station daily. Kioxia will track and analyze this health data to better understand how flash storage performs in the harsh space environment.
