U.3 SSDs for Information Middle Workloads


Micron is taking the wraps off their newest knowledge heart SSD providing at the moment. The 9400 NVMe Collection builds upon Micron’s success with their third-generation 9300 collection introduced again in Q2 2019. The 9300 collection had adopted the U.2 form-factor with a PCIe 3.0 x4 interface, and utilized their 64L 3D TLC NAND. With a most capability of 15.36 TB, the drive matched the highest-capacity HDDs on the storage quantity entrance at the moment (clearly with a lot greater efficiency numbers). Up to now couple of years, the information heart has moved in direction of PCIe 4.0 and U.3 in a bid to maintain up with efficiency necessities and unify NVMe, SAS, and SATA assist. Retaining these in thoughts, Micron is releasing the 9400 NVMe collection of U.3 SSDs with a PCIe 4.0 x4 interface utilizing their now-mature 176L 3D TLC NAND. Elevated capability per die can also be now enabling Micron to current 2.5″ U.3 drives with capacities as much as 30.72 TB, successfully doubling capability per rack over the earlier technology.

Just like the 9300 NVMe collection, the 9400 NVMe collection can also be optimized for data-intensive workloads and is available in two variations – the 9400 PRO and 9400 MAX. The Micron 9400 PRO is optimized for read-intensive workloads (1 DWPD), whereas the Micron 9400 MAX is supposed for combined use (3 DWPD). The utmost capability factors are 30.72 TB and 25.60 TB respectively. The specs of the 2 drive households are summarized within the desk beneath.

The 9400 NVMe SSD collection is already in quantity manufacturing for AI / ML and different HPC workloads. The transfer to a sooner interface, in addition to higher-performance NAND permits a 77% enchancment in random IOPS per watt over the earlier technology. Micron can also be claiming higher all spherical efficiency throughout a wide range of workloads in comparison with enterprise SSDs from rivals.

The Micron 9400 PRO goes towards the Solidigm D7-5520, Samsung PM1733, and the Kioxia CM6-R. The Solidigm D7-5520 is handicapped by decrease capability factors (on account of its use of 144L TLC), leading to decrease efficiency towards the 9400 PRO in all however the sequential reads numbers. The Samsung PM1733 additionally tops out at 15.36TB with efficiency numbers much like that of the Solidigm mannequin. The Kioxia CM6-R is the one different U.3 SSD with capacities as much as 30.72TB. Nonetheless, its efficiency numbers throughout all corners lags nicely behind the 9400 PRO’s.

The Micron 9400 MAX has competitors from the Solidigm D7-P5620, Samsung PM1735, and the Kioxia CM6-V. Apart from sequential reads, the Solidigm D7-P5620 lags the 9400 MAX in efficiency in addition to capability factors. The PM1735 is simply obtainable in an HHHL AIC form-factor and makes use of PCIe 4.0 x8 interface. So, regardless of its 8 GBps sequential learn efficiency, it might probably’t be deployed in a way much like that of the 9400 MAX. The Kioxia CM6-V tops out at 12.8TB and has decrease efficiency numbers in comparison with the 9400 MAX.

Regardless of not being the primary to launch 32TB-class SSDs into the information heart market, Micron has ensured that their eventual providing supplies top-tier efficiency throughout a wide range of workloads in comparison with the competitors. We hope to current some hands-on efficiency numbers for the SSD within the coming weeks.
