When your storage server is expected to handle petabytes or even exabytes of data without taking over your data centre footprint, the Seagate Exos Mozaic 3+ comes into its own. This isn’t marketing spin – it’s the sort of technology that underpins enterprise-scale workloads, hyperscale operations, and increasingly the demands of AI.
What Is the Mozaic 3+ Platform?
Mozaic 3+ is Seagate’s newest hard drive platform, powered by HAMR (Heat-Assisted Magnetic Recording). It manages to pack as much as 3 TB per platter into a standard 3.5-inch drive, offering capacities up to 36 TB. All of this fits neatly into the existing form factor and uses familiar enterprise interfaces, so integration doesn’t require a redesign of your racks.
Why It Matters for Storage Servers
- Huge capacity: A single drive now offers up to 36 TB, reshaping what a storage server can deliver.
- Lower running costs: Seagate estimates 25% less cost per terabyte and as much as 60% less energy use compared to earlier generations.
- Simple upgrades: The drives can slot into existing systems, avoiding expensive reconfigurations.
Real-World Adoption
Mozaic 3+ drives are already being shipped to hyperscale customers. Partners such as Dell are using them in next-generation solutions that support AI, cloud, and other data-heavy services. Some providers are even trialling the 36 TB prototypes in live environments.
Feedback from Testing
Reviews of the 30 TB Exos Mozaic models show consistent transfer speeds in the 275–300 MB/s range. Analysts have noted that it is particularly well-suited to RAID arrays and long-term archiving, with one reviewer calling it “a dream drive for data hoarders”.
Designed for Modern Servers
These drives deliver more density per slot, lower energy use per terabyte, and enterprise-grade reliability. For IT teams, this means stronger performance and efficiency gains without needing to overhaul server hardware.
Where It Fits Best
- AI and data analytics: Ideal for training models and storing massive datasets.
- Cloud platforms: Perfect for service providers who need predictable, large-scale capacity with lower overheads.
- Archives and compliance: Allows organisations to store decades of records with fewer drives and simpler management.
Sustainability and Cost Benefits
By fitting more data onto fewer drives, Mozaic 3+ helps reduce rack space, power usage, and cooling requirements. For anyone managing storage servers, that means not only cost savings but also a meaningful cut to environmental impact.
Looking Ahead
With AI, IoT, and edge services growing, the need for storage won’t slow down. Mozaic 3+ is a step forward today, but it also signals where things are heading – towards even greater density and efficiency. It’s about ensuring data centres can keep up without endless hardware sprawl.
Final Thoughts
The phrase storage server captures the backbone of digital infrastructure, and Seagate’s Exos Mozaic 3+ drives are built to strengthen that backbone. With standout density, energy savings, and easy deployment, they deliver practical advantages that meet the realities of modern data growth.
