Solidigm ships 122TB SSD with unlimited 5-year random-write endurance; 84% less NAS power than HDD+TLC
Solidigm announced it is now shipping the D5-P5336, the world's highest-capacity PCIe SSD at 122TB (actual 122.88TB), and the first SSD with unlimited random-write endurance over a 5-year period. The drive, sampling to customers since announcement and now in production, doubles Solidigm's earlier 61.44TB model. SK Hynix subsidiary Solidigm uses 192-layer QLC (quad-level cell) NAND and maintains the same controller across its 7TB-to-122TB product line, simplifying customer qualification and deployment at scale.
The drive consumes up to 84% less storage power in NAS deployments versus legacy HDD+TLC solutions, delivers 3.4x more terabytes per watt than 30TB TLC drives, and enables up to 4 petabytes of storage per rack unit with a 4:1 footprint reduction versus hybrid HDD+TLC. Power draw is 24 watts active and 5 watts idle—competitive with traditional PCIe 4.0 SSDs despite 2x the capacity. Sequential reads hit 7.4 GB/s (saturating PCIe Gen4), while endurance is rated at 0.6 DWPD (drive writes per day), or 134.3 petabytes written over the warranty period.
The 122TB drive targets AI data pipelines, object storage tiers, and hyperscale deployments where space and power constraints are acute. Micron is shipping a competing 122TB 6600 ION PCIe 5.0 SSD, and Solidigm has public roadmaps to ~245TB drives in 2026 as SK Hynix ramps 321-layer QLC. The move signals broader industry shift from HDD+SSD hybrid architectures toward all-flash data centers driven by AI workload density and energy-per-terabyte math. Dell has already integrated the drive into PowerScale systems.
For architects: 122TB-class SSDs change the storage-vs.-compute trade-off for AI inference and training pipelines. Teams building greenfield data center stacks should evaluate all-SSD architectures where density + power efficiency beat per-GB cost of HDDs. The unlimited random-write endurance claim is contingent on 32KB I/O patterns; 4K random write endurance sits lower (12% remaining after 5 years per spec). Customers should validate random I/O profiles in their workloads before committing capacity. NeoCloud providers and AI infrastructure operators (CoreWeave, Lambda, Crusoe) are early adopters.
