HPE 4 TB SATA hard drive

The HPE 861683-B21 is a 4 TB 3.5-inch internal hard drive built for entry-level servers and external storage arrays. It targets workloads of forty percent or less such as backup and archival tasks.

3.5-inch hot-swap tray included

A 3.5-inch form factor with an attached tray enables hot-swap installation in compatible bays without tools. The SATA 6.0 Gb/s connector provides standard power and data cabling for straightforward integration.

SATA 6.0 Gbps interface limit

The SATA 6.0 Gb/s interface caps sequential throughput below the drive’s mechanical potential. Average seek time of 7.45 ms and 7200 RPM rotational speed define random-access latency for low-workload use.

Questions about this item

What does the SATA 6.0 Gb/s interface limit in practice?

The SATA 6.0 Gb/s interface caps the maximum data transfer rate at 6 Gb/s, so sustained throughput cannot exceed that link speed.

What physical space and mounting does the 3.5-inch form factor with tray attached require?

The drive needs a standard 3.5-inch large form factor bay and uses the attached tray for hot-swap mounting in compatible HPE server or storage chassis.

How is the drive installed and which step is often missed?

Slide the tray-attached drive into a hot-swap bay until the latch clicks; the step often missed is ensuring the latch fully engages to secure both power and data connections.
