2TB WD HGST SATA6 7200RPM 128MB Ent.

Product Description

Data centers face growing pressures to store more with flat-to-shrinking budgets. Keeping systems operational for as long as possible to maximize investments can be an effective part of the strategy, but supporting those legacy applications becomes even more challenging as drive technologies move to next generation formats and interfaces. Ultrastar 7K2 has a SATA 6Gb/s interface and native 512-byte (512n) sector size to provide consistent, high performance and compatibility with legacy data center applications. Enhanced RAFF technology in the 7K2 includes sophisticated electronics to monitor the drive and correct both linear and rotational vibration disturbances in real timeespecially helpful in multi-drive arrays and rack-mounted systems maintaining high read/write performance. Designed to handle workloads up to 550TB per year, the Ultrastar 7K2 delivers up to 2TB of affordable storage capacity for high-intensity applications in enterprise-class environments Detail Specifications Interface SATA 6Gb/s Capacity (GB) 2TB Sector Size (Variable, Bytes/sector) 512 native (512n) Max Areal Density (Gbits/sq. in.) 638 Performance Data Buffer (MB): 128 Rotational Speed (RPM): 7200 Latency Average (ms): 4.2 Interface Transfer Rate (MB/sec, max): 600 Sustained Transfer Rate (MB/sec, typ.): MB/s: 200 MiB/s: 191 Seek Time (read, ms, typical): 7.7 / 8.3 Reliability Error Rate (non-recoverable, bits read): 1 in 1015 MTBF (M hours):2.0 Annual Failure Rate (AFR): 0.44% Load/Unload Cycles: 600,000 Availability (hrs/day x days/wk): 24x7 Acoustics Idle (Bels): 2.5 / 2.8 Power Requirement: +5V, +12V Operating (W, typical): 8.1 Idle (W): 5.9 Power Consump.
