Western Digital Ultrastar DC HC310 6 TB 7200 RPM SAS 12 Gb/s 3.5-inch Internal HDD

The Western Digital Ultrastar DC HC310 is a 6 TB, 7200 RPM, SAS 12 Gb/s 3.5-inch internal hard drive designed for enterprise environments. It is built for continuous 24/7 operation, handling workloads that exceed standard desktop duty cycles. Administrators typically use this drive in server racks and workstations that require sustained access to large datasets. Its standard form factor ensures compatibility with most multi-bay server chassis.

This drive requires a host controller compatible with professional storage networks. Because it uses enterprise SAS protocols rather than consumer SATA, it is intended for use in data centres and server infrastructure. The drive’s mechanical design is optimized for consistent read and write performance, ensuring stable throughput during extended network sessions. The unit weighs 715 grams.

• 255 MB/s sequential read and write speeds: Supports high-speed data transfer during sustained network activity.
• 256 MB cache: Reduces access latency during active server workloads.
• 2,000,000-hour mean time between failures (MTBF): A measure of expected hardware reliability.
• 12.1 W active power consumption: Energy usage during periods of high disk activity.
• 7 W idle power draw: Energy usage during periods of inactivity.
