Deskstar 7K1000.C 500GB SATA drive

The HGST HDS721050CLA662 is a 3.5-inch desktop hard drive with a 500GB capacity and a 7200 RPM spindle speed. It connects through a SATA 6.0Gb/s interface and includes 16MB of cache. The unit is supplied as a bare drive and carries a refurbished condition. It is intended for power computing workloads that benefit from mechanical storage.

Refurbished bare drive implications

Because the drive arrives without retail packaging, cables, mounting screws or installation software, the builder must provide SATA data and power cables separately. The refurbished status means the unit has been tested and restored to working order, but original manufacturer warranty terms may differ from a new retail package. No bundled utilities or diagnostic discs are included in the shipment.

Mechanical design and daily use

The 3.5-inch form factor fits standard desktop drive bays and backplanes using industry-standard SATA connectors. Features such as HiVERT technology, an internal thermal sensor and advanced power management help regulate heat and power draw during sustained operation. Head load and unload technology plus thermal fly-height control protect the platters during spin-up and shutdown cycles. ECC and CRC protection guards data integrity across the 500GB capacity.

商品問答

What maintenance or replacement will the 16MB cache and 7200 RPM mechanical parts need later?

The drive uses Head Load/Unload Technology to reduce mechanical wear, and an Internal Thermal Sensor monitors temperature; no user-serviceable parts exist, so replacement is the only option if the mechanism fails.

Which limit appears first under sustained use — the 8.9ms average seek time or the SATA 6.0Gb/s interface ceiling?

Sustained transfers are capped by the mechanical 7200 RPM platters and 16MB cache, so the drive hits its own throughput ceiling well before the SATA 6.0Gb/s link saturates.

How much noise, heat or power does the 3.5" Deskstar 7K1000.C produce when running all day?

HiVERT Technology and Advanced Power Management lower power draw and heat during idle periods, while the Internal Thermal Sensor and Thermal Fly-height Control keep temperatures stable under continuous operation.
