10 TB helium-sealed enterprise drive

The HGST Ultrastar DC HC510 is a 3.5-inch internal hard drive built for continuous operation in NAS, DAS, workstation and server environments. Its helium-sealed design reduces drag and power draw while supporting a 550 TB annual workload rating. The drive uses conventional magnetic recording and a 512e advanced format.

256 MB cache and Instant Secure Erase

A 256 MB buffer helps absorb burst write traffic from multi-user workloads. Instant Secure Erase allows cryptographic sanitisation without physical destruction, simplifying drive retirement in regulated environments. The 512e format maintains compatibility with legacy operating systems and storage controllers.

Standard SATA installation, no special tooling

The drive fits any 3.5-inch bay and connects with ordinary SATA data and power cables. No additional drivers or firmware utilities are required for basic operation. Ensure the host system can supply adequate 12 V current for the helium platform during spin-up.

Questions about this item

Does the helium-sealed 10TB HUH721010ALE600 need any internal parts replaced over its service life?

The drive is a hermetically sealed helium unit with no user-serviceable components; it is rated for 550TB per year and 2.5 million hours MTBF under continuous 24×7 operation.

What sustained transfer ceiling appears first when the 7200 RPM CMR drive runs flat-out?

Sequential throughput tops out at 249 MB/s, so the SATA 6.0Gb/s interface and mechanical media set the practical ceiling before any thermal throttle engages.

How much noise and heat does the 3.5" Ultrastar DC HC510 produce in an all-day server workload?

Designed for 24×7 enterprise use, the helium-sealed 10TB model meets a 550TB/year workload rating and 0.35% AFR while operating within standard 3.5" power and acoustic envelopes.
