Seagate manufactures hard drives that specifically address the needs of the hyperscale storage market. As the highest-performing hard drive in the Seagate® X class, the Exos® 2X18 enterprise dualactuator hard drive utilises MACH.2™ technology enabling up to 2× the performance of an enterprise single-actuator 3.5-inch hard drive.
- MACH.2 technology enables up to 2× the performance of an enterprise singleactuator 3.5-inch hard drive
- Highest 18 TB hard drive performance, making it the logical choice for cloud data centre and massive scale-out data centre applications. Available as two independently addressable, 9 TB logical units for SAS or one 18 TB logical device for SATA
- PowerBalance™ feature optimises IOPS/Watt
- Helium sealed-drive design delivers lower total cost of ownership through lower power and weight
- Next-generation helium side-sealed weld technology for added handling robustness and leak protection
- Digital environmental sensors to monitor internal drive conditions for optimal operation and performance
- Latest hermetic interconnect technology supporting higher data rate heads and higher pin counts for extreme thermal conditions
- Proven enterprise-class reliability backed by 5-year limited warranty and 2.5M-hr MTBF rating.
