Capacity and interface

This HP 454146-S21 is a 1TB 3.5" internal hard drive with a SATA 3.0Gb/s interface. It spins at 7200 RPM and is supplied as a bare drive. The drive targets server and storage environments that need large-capacity magnetic storage.

Server workloads versus desktop or portable needs

The drive suits entry-level servers and non-mission-critical workloads where cost per gigabyte matters. It is not for systems that require solid-state speed, silent operation or a 2.5" form factor. Buyers needing higher throughput or hot-plug trays should look at other drive classes.

SATA 3.0Gb/s interface

The single specification that decides fit is the SATA 3.0Gb/s interface with a maximum external transfer rate of 300 MBps. The host must provide a matching SATA port and 3.5" bay; drives with newer or faster interfaces will not work in this slot.

Questions about this item

What does the 7200 RPM spindle speed mean for everyday server workloads?

The 7200 RPM rotation gives faster random access than slower drives, which helps with typical server tasks such as file serving or database logging.

How does the SATA 3.0Gb/s interface limit real-world throughput?

The SATA 3.0Gb/s link caps the maximum external transfer rate at 300 MBps, so sustained reads and writes cannot exceed that ceiling.

Will this 3.5 inch bare drive fit a standard server drive bay?

Yes, the 3.5 inch form factor matches the common large form factor bays used in many rack and tower servers.
