DapuStor Launches Up to 122TB J5060 U.2 PCIe 4.4 x4 NVMe 1.4a QLC SSD

DapuStor Corp. announces the launch of its ultra-high capacity J5060 QLC U.2 SSD, delivering an 122.88TB of capacity – twice that of its predecessor, the 61TB J5060; this milestone redefines what’s possible in high-density flash storage.

Massive Capacity, Minimal Footprint
For personal users, the J5060 122TB 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 24TB HDDs with the J5060 can reduce system footprint and complexity by up to 5x, significantly lowering equipment count and saving valuable data center space.

Power Efficiency
The J5060 isn’t just about capacity – it’s engineered for power efficiency. Delivering up to 7,300MB/s read speeds at just 13W, and maxing out under 25W, it offers a best-in-class data-per-watt ratio. This leap in efficiency makes it for sustainable, high-density storage environments.

Optimized Performance for Read-Centric Workloads
Like the 61TB model, the 122TB 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 7.3GB/s
Sequential Write: up to 2.8GB/s
4K Random Read: 1.5M IOs
32KB Random Write: 15K IOs
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 IOs / 7.1W = 77
J5060: 15,000 IOs / 25W = 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 and 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 10PB deployment:

Using 24TB HDDs significantly increases device count and operational costs
A J5060-based architecture reduces TCO by up to 35% over 5 years.

Industry-Proven QLC Adoption
Enterprise-grade QLC SSDs have already gained widespread radoption. From 2018 to 2024, leading U.S. vendor Solidigm shipped over 100 exabytes of QLC SSDs. Over 70% of the top 5 Fortune 500 AI OEMs now use QLC SSDs at scale.

As a pioneer in QLC eSSD development, DapuStor offers a range of products – from 7.68 to 122.88TB, available in both single and dual-port configurations. Surpassing 100TB introduces new engineering challenges, but the company 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.
