Description
Exos X18
Seagate manufactures hard drives that specifically address the demand for hyperscale cloud scalability. As the flagship of the Seagate® X class, the Exos® X18 enterprise hard drives are the highest-capacity hard drives in the fleet.
Maximum Storage Capacity for Highest Rack Space Efficiency
- Market-leading 18 TB HDD offering the highest capacity available for more petabytes per rack
- Highly reliable performance with enhanced caching, making it the logical choice for cloud data centre and massive scale-out data centre applications
- Hyperscale SATA model tuned for large data transfers and low latency
- PowerBalance™ feature optimises Watts/TB
- Maximise total cost of ownership savings through lower power and weight with helium sealed-drive design
- Proven helium side-sealing weld technology for added handling robustness and leak protection
- Digital environmental sensors to monitor internal drive conditions for optimal operation and performance
- Data protection and security — Seagate Secure™ features for safe, affordable, fast and easy drive retirement
Best-Fit Applications
- Scalable hyperscale applications/cloud data centres
- Massive scale-out data centres
- Big data applications
- High-capacity density RAID storage
- Mainstream enterprise external storage arrays
- Distributed file systems, including Hadoop and Ceph
- Enterprise backup and restore —D2D, virtual tape
- Centralised surveillance
