The MG04 series is engineered for nearline business-critical workloads. The 3.5 inch (8.9 cm) Enterprise HDDs are available in capacities up to 5TB and feature Toshiba Persistent Write Cache technology. Equipped with 6Gbit/s SATA interface, the series supports higher storage density, saving rack space and reducing the footprint and operational burden of business critical servers and storage systems. The drives are available in models that support either 512e or 4Kn advanced format storage modes. The 4Kn drives (MG04ACAxxxA) offer optimum performance and compatibility with the latest applications and operating environments. The 512e compatible drives (MG04ACAxxxE) provide support for legacy applications and operating environments that require 512byte sector lengths. Specification:  Hard drive Component for Server/workstation HDD sustained transfer rate 195 MiB/s HDD interface transfer rate 6 Gbit/s Average latency 4.17 ms Mean time between failures (MTBF) 1400000 h HDD speed 7200 RPM HDD size 3.5" HDD capacity 4000 GB Features Type HDD Component for Server/workstation HDD sustained transfer rate 195 MiB/s HDD interface transfer rate 6 Gbit/s Interface Serial ATA III Average latency 4.17 ms Mean time between failures (MTBF) 1400000 h HDD speed 7200 RPM HDD size 3.5" HDD capacity 4000 GB Storage drive buffer size 128 MB Power Operating voltage 5 / 12 V Power consumption (write) 11.3 W Power consumption (read) 11.3 W Power consumption (idle) 6 W Operational conditions Operating temperature (T-T) 5 - 55 °C Storage temperature (T-T) -40 - 70 °C Operating relative humidity (H-H) 5 - 90% Storage relative humidity (H-H) 5 - 95% Operating altitude -12007.9 - 120000" (-305 - 3048 m) Non-operating altitude -12007.9 - 480000" (-305 - 12192 m) Operating vibration 0.75 G Operating shock 70 G Non-operating vibration 5 G Non-operating shock 300 G Technical details Operating voltage 5 / 12 V Interface Serial ATA III Mean time between failures (MTBF) 1400000 h Weight & dimensions Width 4.01" (101.8 mm) Weight 25.4 oz (720 g) Height 5.79" (147 mm) Depth 1.03" (26.1 mm) Other features Operating voltage 5 / 12 V Interface Serial ATA III
