DapuStor Unveils J5060 QLC 122 TB Ultra Capacity SSD Series
Massive Capacity, Minimal Footprint
For personal users, the J5060 122 TB SSD can store up to 10,000 90-minute 4K movies, all in a device that fits in the palm of your hand—a perfect combination of capacity and portability. For enterprise deployments, the benefits are even greater. Replacing 24 TB HDDs with the J5060 can reduce system footprint and complexity by up to 5x, significantly lowering equipment count and saving valuable data center space.
Exceptional Power Efficiency
The J5060 isn’t just about capacity—it’s engineered for power efficiency. Delivering up to 7,300 MB/s read speeds at just 13 W, and maxing out under 25 W, it offers a best-in-class data-per-watt ratio. This leap in efficiency makes it ideal for sustainable, high-density storage environments.
Optimized Performance for Read-Centric Workloads
Like the 61 TB model, the 122 TB J5060 is engineered for large, sequential data workloads. It uses coarse-grained (large-granularity) mapping and a dual-PCB hardware design to minimize DRAM usage and overcome capacity limitations. Performance highlights include:
- Sequential Read: up to 7.3 GB/s
- Sequential Write: up to 2.8 GB/s
- 4K Random Read: 1.5M IOPS
- 32 KB Random Write: 15K IOPS
- 4K Random Read Latency: as low as 105μs
More Cost-Effective than HDDs
Source data: HDD performance based on U.S. top-tier vendor datasheets.
Power efficiency calculated as:
- HDD: 550 IOPS / 7.1 W = 77
- J5060: 15,000 IOPS / 25 W = 600
- Efficiency Gain: 7.8x higher than HDDs
The J5060 not only offers 5x the capacity of mainstream HDDs but also dramatically outperforms them. In AI workloads involving random reads and sequential writes, it delivers:
- 9,000x faster random read performance
- 10x faster sequential write performance
Lower Failure Rates & Better TCO
Reliability is key for enterprise infrastructure. As of Q4 2024:
- DapuStor J5 series SSDs show failure rates below 0.04%
- HDDs report an Annualized Failure Rate (AFR) of 1.70% (Source: Backblaze Drive Stats, 2023)
Unlike HDDs, which suffer from mechanical wear and vibration, SSD reliability can be enhanced over time via firmware updates.
For a 10 PB deployment:
- Using 24 TB HDDs significantly increases device count and operational costs
- A J5060-based architecture reduces Total Cost of Ownership (TCO) by up to 35% over five years.
Industry-Proven QLC Adoption
Enterprise-grade QLC SSDs have already gained widespread adoption. From 2018 to 2024, leading U.S. vendor Solidigm shipped over 100 exabytes of QLC SSDs. Over 70% of the top five Fortune 500 AI OEMs now use QLC SSDs at scale.
As a pioneer in QLC eSSD development, DapuStor offers a comprehensive range of products—from 7.68 TB to 122.88 TB, available in both single and dual-port configurations. Surpassing 100 TB introduces new engineering challenges, but DapuStor has successfully validated its solutions with leading enterprise customers.
From record-breaking capacity to industry-leading efficiency, DapuStor’s QLC SSDs deliver the flexibility, performance, and reliability to meet the evolving needs of modern data infrastructure.
