Controller Master


Kioxia Corporation today announced that its KIOXIA PM7 Series of enterprise SAS SSDs are now available for customer evaluation. Targeted at enterprise applications and use cases – including high-performance computing, artificial intelligence, caching layer, and financial trading and analysis – the new drives bring improved performance, reliability and security to enterprise servers and storage. With an emphasis on security, the PM7 Series is FIPS 140-2 certified and currently under test for FIPS 140-3 certification.

Designed for modern IT infrastructures, 24G SAS (SAS-4) doubles effective bandwidth over 12 Gb/s SAS (SAS-3). Featuring Kioxia’s 5th generation BiCS FLASH 3D flash memory, the PM7 Series delivers sequential read performance of up 4.2 Gigabytes (GB) per second (GB/s) and 720K random read IOPS, achieving approximately 20% performance improvement over the previous generation KIOXIA PM6 Series. The new Kioxia drives are available in capacities up to 30.72 terabytes (TB), making them the industry’s highest capacity 2.5-inch SAS SSD.

Additional features include:

  • Dual-port to support redundancy for storage systems that require high reliability.
  • Flash Die Failure Protection – a Kioxia feature that allows for transparent disabling of a failing flash chip, while maintaining full reliability at the SSD level.
  • Endurances for a wide range of workloads; read-intensive (1DWPD) and mixed-use (3DWPD).
  • Security options available; sanitize instant erase (SIE), TCG Enterprise self-encrypting drive (SED) and FIPS 140-2 certification. FIPS 140-3 certification is in process and is expected to be completed in 2022.

Kioxia is an active member of the T10 and SCSI Trade Association industry groups that head up and define SAS development efforts, driving innovation and development of the SAS interface.
