Kioxia PM7 Series of Enterprise 24Gb SAS Up to 31TB 2.5-Inch SSDs Available for Customer Evaluation

Kioxia America, Inc. announced that its PM7 Series of enterprise SAS SSDs is available for customer evaluation.

The company was the first ⁽¹⁾ to bring 24Gb SAS to server and storage applications, and now the PM7 Series, its 2nd gen of 24Gb SAS SSDs.

Targeted at enterprise applications and use cases – including HPC, AI, caching layer, and financial trading and analysis -, these drives bring improved performance, reliability and security to enterprise servers and storage. With an emphasis on security, the PM7 Series is FIPS ⁽²⁾ 140-2 certified and currently under test for FIPS 140-3 certification.

Designed for modern IT infrastructures, 24Gb SAS (SAS-4) doubles effective bandwidth over 12Gb SAS (SAS-3). Featuring the company’s 5th gen BiCS flash 3D TLC flash memory, the PM7 Series delivers sequential read performance of up 4.2GB/s, 720,000 random read IO/s and up to 355,000 random write IO/s. These SSD drives are available in capacities up to 30.72TB, making them the industry’s highest capacity ⁽³⁾ 2.5″ ⁽⁴⁾ SAS SSD.

“SAS has proven itself as the tried and trusted storage technology for the enterprise storage market,” commented Don Jeanette, VP, SSD research, Trend Focus. “As SAS continues strong shipments in 2022, Kioxia’s 24G SAS SSD leadership will help them to maintain their market share in enterprise servers and storage.”

The PM7 Series builds upon the company’s history of performance and reliability over 7 gens of SAS drives, nearly doubling the performance of the firm’s 12Gb SAS SSDs and realizing up to 20% performance gains over its previous gen 24Gb SAS SSD.

Additional features include:

• Dual-port for HA.

• Flash Die failure protection – a firm’s feature that allows for transparent disabling of a failing flash chip, while maintaining reliability at the SSD level.

• Endurances for a range of workloads; read-intensive (1 DWPD ⁽⁵⁾) and mixed-use (3 DWPD).

• Security options available, including sanitize instant erase (SIE ⁽⁶⁾), TCG Enterprise self-encrypting drive (SED ⁽⁷⁾) and FIPS 140-2 certification. FIPS 140-3 certification is in process and is expected to be completed in 2022.

“As active members of the T10 and SCSI Trade Association industry groups that head up and define SAS development efforts, Kioxia is proud to be leading the transition to 24G SAS,” said Neville Ichhaporia, VP, SSD marketing and product management. “Our SSD portfolio for the data center is the broadest in the industry ⁽⁸⁾, and the addition of the PM7 Series is more proof of our commitment to drive innovation and development of the widely deployed and trusted SAS interface.“

⁽⁴⁾ ‘2.5-inch’ indicates the form factor of the SSD. It does not indicate the drive’s physical size.
⁽⁵⁾ DWPD: Drive Write(s) Per Day. One full drive write per day means the drive can be written and re-written to full capacity once a day every day under the specified workload for the specified lifetime. Actual results may vary due to system configuration, usage and other factors.
⁽⁶⁾ SIE: Sanitize Instant Erase option supports Crypto Erase, which is a standardized feature defined by the technical committees (T10) of INCITS (the International Committee for Information Technology Standards).
⁽⁷⁾ SED: Self-Encrypting Drive option supports TCG Enterprise SSC.
⁽⁸⁾ Based on Kioxia America survey of publicly available information as of August 2021.
Read and write speed may vary depending on various factors such as host devices, software (drivers, OS etc.), and R/W conditions.
IO/s: Input Output Per Second (or the number of I/O operations per second)
Sample drives are for evaluation. The specs of sample drives may differ from production drive models.
