High-Capacity 3.5-Inch SATA Drive

The HP 793695-B21 is an 8TB 3.5-inch internal hard drive that spins at 7200 RPM over a SATA interface. It is built for desktop workstations and bulk-storage arrays that need large capacity on a standard drive bay.

Suited for Mass Storage, Not Speed-Critical Roles

This drive suits users who prioritise capacity per bay for media libraries, backups or archival workloads. It is not for builds that demand the low latency or high random IOPS of solid-state storage.

7200 RPM Spindle Speed Determines Throughput

The 7200 RPM spindle speed is the key specification that sets sustained transfer rates for sequential workloads. Buyers should verify that their workload benefits from this rotational speed before selecting the drive.

Questions about this item

Will this 7200 RPM SATA drive work alongside older SATA disks already in my PC?

Yes, the 793695-B21 uses the standard SATA interface, so it can share the same controller with older SATA drives without configuration changes.

What must my desktop already have to install this 3.5" 8TB drive?

You need a free 3.5-inch drive bay, a spare SATA data port on the motherboard, and a SATA power connector from the power supply.

How can I confirm the 8TB capacity and 7200 RPM speed are recognised after setup?

Check the BIOS or operating system disk utility; it should report 8TB capacity, 512e sector format, and 7200 RPM rotational speed.
