As enterprise data demands skyrocket in 2025, storage professionals globally are searching for high-capacity SSD solutions. Seagate, as a leader in enterprise storage, continues pushing boundaries with its Exos X series – but how do these drives compare against competitors’ largest offerings? Let’s examine today’s maximum SSD capacities and their real-world applications.
Breaking down the current largest SSDs in enterprise market
As of November 2025, Seagate’s Exos X24 leads the pack with a 61.44TB capacity in 2.5″ U.2 form factor, specifically designed for hyperscale data centers. Key specifications:
- Interface: PCIe 5.0 x4 with NVMe 2.0 support
- Sequential read/write: 14,000/7,000 MB/s
- DWPD (5-year warranty): 1.0
- Power consumption: 25W active
Competitors like Samsung PM1663 and Kioxia XL-FLASH offer similar capacities (61.44TB and 32TB respectively), but Seagate’s solution provides better $/TB ratio at approximately $8,500 per unit in bulk purchases – about 12% lower than comparable options.
How enterprise SSD endurance affects total cost of ownership
When evaluating massive SSDs, endurance metrics become critical. The Exos X24’s 1 DWPD (Drive Writes Per Day) means it can handle 61.44TB of writes daily for 5 years – equivalent to about 112PB total. Comparatively:
| Model | Endurance Rating | Total Bytes Written |
|---|---|---|
| Seagate Exos X24 | 1 DWPD | 112PB |
| Samsung PM1663 | 0.8 DWPD | 90PB |
| Kioxia XL-FLASH | 3 DWPD | 175PB |
While Kioxia offers higher endurance, their 32TB capacity requires more drives for equivalent storage, increasing rack space and power requirements. For most cloud providers, Seagate’s balance of capacity and endurance proves optimal.
Real-world applications for petabyte-scale SSD storage
These massive SSDs aren’t just for bragging rights – they solve specific enterprise challenges:
- AI training datasets: Storing uncompressed training data locally reduces GPU idle time. A single 61TB drive can hold about 8 million high-resolution medical images.
- Financial transaction logging: High-frequency trading systems require sub-millisecond access to transaction records spanning months.
- Video rendering farms: 8K video projects often exceed 10TB per hour of footage, requiring fast scratch disks.
Interestingly, many hyperscalers now deploy these drives in 20% read-intensive/80% write-intensive configurations to optimize endurance across different workloads.
