Capacity and interface

The HPE 801888-B21 is a 4 TB internal hard drive with a SATA 6.0 Gb/s interface and a 7200 RPM spindle speed. Its 3.5 inch form factor fits standard desktop and server drive bays. The drive is supplied new and intended for non-hot-plug installation.

Suited for bulk storage, not for hot-swap

This drive suits users who need economical high-capacity storage for non-mission-critical workloads such as file archives, backups or media libraries. It is not designed for hot-swap bays, so builders who require hot-plug capability should look elsewhere. It also targets traditional hard-drive workloads rather than solid-state performance tiers.

SATA 6.0 Gb/s interface

The single specification that determines compatibility is the SATA 6.0 Gb/s interface; the system must provide a matching SATA port and 3.5 inch mounting space. The 7200 RPM speed and 4 TB capacity follow from that interface choice. Verify the host supports SATA 6.0 Gb/s before purchase.

Questions about this item

Does my system need a free 3.5" drive bay and a SATA 6.0Gb/s port to install this 801888-B21 drive?

Yes, the drive requires a standard 3.5-inch internal bay and a SATA 6.0Gb/s data connection plus a SATA power connector from the power supply.

Will this 7200 RPM SATA drive work reliably alongside older 3.0Gb/s SATA drives in the same server?

The drive is backward compatible with SATA 3.0Gb/s controllers, so it will operate at the slower link speed when paired with older drives on the same bus.

How can I verify the 801888-B21 is running at its full 6.0Gb/s link speed after installation?

Check the negotiated link speed in the system BIOS or using a tool such as smartctl; it should report 6.0Gb/s when the controller supports it.
