Samsung Nearline SSD Roadmap Could Reach 1PB, Says Scality

Posted on
Scality says Samsung is developing nearline SSDs from 250TB to 1PB, targeting high-density, low-write workloads with far lower endurance than current QLC.

Quick Report

Scality said in a briefing that Samsung is developing nearline SSDs with capacities starting around 250TB and scaling up to 1PB in E3.L or E2 form factors. The claim came from Scality executives describing ongoing co-development work and lab validation for next-generation high-density flash aimed at replacing nearline HDD use cases.

According to Scality, these drives use a new flash type with endurance around 0.1 drive writes per day for five years, which is materially lower than current QLC levels around 0.5 DWPD. Despite that endurance tradeoff, Scality said early lab tests show performance close to QLC, suggesting a read-optimized profile for archive and low-write object storage tiers.

If those density targets ship, a 4RU shelf could hold close to 50PB and a full rack could approach half an exabyte, making power and floor-space efficiency far better than HDD-heavy designs for suitable workloads. Scality also indicated Samsung nearline flash products are unlikely this year, implying a later launch window.
