Deskstar E7K1000 1 TB SATA Drive

The Deskstar E7K1000 is a 1 TB 3.5-inch internal hard drive built for power-conscious enterprise environments. It operates at 7200 rpm with a 32 MB buffer and connects through a SATA/300 interface. Hot-swap capability simplifies drive replacement in compatible bays.

Build Integration SATA Hot-Swap

The drive fits standard 3.5-inch internal bays and uses the SATA interface for data and power. Hot-swap support allows removal without shutting down the host system. A SATA backplane or controller with hot-plug support is required to use this feature. The 1.50 lb weight suits typical drive cages.

Sustained Enterprise Workload

Designed for continuous operation, the drive balances performance with low thermal output. Power management features help maintain stable temperatures during extended use. The 7200 rpm spindle speed supports steady throughput for server and storage workloads. Not for buyers who need faster interfaces or larger capacities.

Questions about this item

At what spindle speed does the 7200 rpm drive hit its thermal ceiling under sustained load?

The drive spins at 7200 rpm with a 32 MB buffer, and its marketing highlights best-in-class power management and thermal emissions for extended operation.

How much heat and noise does the 3.5" SATA/300 drive produce when running continuously?

The Deskstar E7K1000 series is engineered for low thermal emissions and efficient power management, helping to minimise heat and acoustic output in always-on deployments.

What host interface and hot-swap capability must my server backplane provide for this 1 TB drive?

The drive uses a SATA/300 interface and is hot-swappable, so the backplane must support SATA 3 Gbit/s connections with hot-plug functionality.
