Description
Ultrastar DC HC320 (aka 7K8)
8TB 3.5-inch Enterprise Hard Drive Economical Capacity – Helps address budget and access requirements High Performance – Up to 12% faster than prior generation Ultrastar 7K6000 Drop-in Ready – Designed for traditional storage and server applications As the industry evolves to develop purpose-built solutions for growing data storage requirements, IT managers continue to rely on lower capacity drives that are economical to acquire, yet deliver quick and reliable data access for traditional data center applications. Ultrastar 7K8 is an 8TB HDD that helps address economic and access requirements of many traditional IT workloads. Lower capacity drives also help address architecture limitations. The Ultrastar 7K8 is designed for traditional storage and server applications as well as distributed and scalable computing, including block and file storage architectures, providing fast 7200 RPM performance and lower acquisition cost to help ease budget constraints.

CAPACITY: One MB is equal to one million bytes, one GB is equal to one billion bytes and one TB equals 1,000GB (one trillion bytes) when referring to hard drive capacity. Accessible capacity will vary from the stated capacity due to formatting and partitioning of the hard drive, the computer’s operating system, and other factors. 
MTBF/AFR: Specifications are based on a sample population and are estimated by statistical measurements and acceleration algorithms under typical operating conditions for this drive model. MTBF and AFR ratings do not predict an individual drive’s reliability and do not constitute a warranty.
SECTOR SIZE: Advanced Format drive: 4K (4096-byte) physical sectors. 
DATA BUFFER: Portion of buffer capacity used for drive firmware. 
TRANSFER RATE: Projected performance. Actual performance may vary. MiB/s is 1048576 Bytes/sec, MB/s is 1000000 Bytes/sec. 
SEEK TIME: Excludes command overhead. 
OPERATING POWER: Calculated based on a Random RW workload; SATA: 8K Queue Depth = 1 @ 40 IOPS; SAS: 4K Queue Depth = 4.
LOW POWER IDLE: Based on use of Idle_A
