Supermicro (Seagate) 18TB 3.5" 7200RPM SAS3 Dual-Actuator 12Gb/s 256M Internal Hard Drive (HDD-3A18T-1FECR)

Highest Performance 18TB for Highest Rack Space Efficiency

As the highest-performing hard drive in the Seagate® X class, the Exos® 2X18 enterprise dual-actuator hard drive utilizes MACH.2™ technology enabling up to 2× the performance of an enterprise single-actuator 3.5-inch hard drive.

Ideal for cloud data centers and massive scale-out data center applications. Available as two independently addressable, 9TB logical units for SAS or one 18TB logical device for SATA. The PowerBalance™ feature optimizes IOPS/Watt. The helium sealed-drive design delivers a lower total cost of ownership through lower power and weight. The helium side-sealed weld technology provides added handling robustness and leak protection. The digital environmental sensors monitor internal drive conditions for optimal operation and performance. The latest hermetic interconnect technology supports higher data rate heads and higher pin counts for extreme thermal conditions.
