Is this drive meant for a home NAS?

Yes, it works in NAS units with 3.5-inch SATA bays, and its capacity suits large media and backup pools. Check that your NAS supports drives of this capacity and is rated for 7200 RPM enterprise drives.

How does it compare with Seagate's IronWolf drives?

Exos is Seagate's enterprise line, tuned for servers and heavy 24/7 workloads. IronWolf is the NAS-focused line with firmware features aimed at multi-bay consumer and small-business NAS. Both use SATA and 3.5-inch mounting.

Will it work in a desktop PC?

It fits any desktop with a 3.5-inch bay and a free SATA port. It is louder and warmer than a typical desktop drive, so plan airflow and expect some seek noise.

What is the difference between this and an SSD?

This is a spinning hard drive: strong sequential throughput and huge capacity, but far slower random access than an SSD. Use it for bulk storage and keep the operating system and active projects on an SSD.

Does it need special mounting?

Standard 3.5-inch mounting works. In arrays with several drives, use anti-vibration mounts or trays where your chassis offers them, since vibration from neighboring drives affects performance.

What comes in the box?

The drive itself. SATA cables, screws and trays are not included, so have those on hand for a new build.

Our take on the Seagate Exos 28TB 7.2K RPM SATA 6Gb/s 3.5" Enterprise HDD - ST28000NM000C

The Seagate Exos ST28000NM000C is a 28TB enterprise hard drive built for servers, NAS boxes and direct-attached storage. It spins at 7200 RPM over SATA 6Gb/s with a 512 MB cache and rated read speeds up to 270MB/s, so it is a fast mechanical drive for its class. Its appeal is capacity per bay: one 3.5-inch slot holds 28TB, which cuts the drive count and power draw a large array needs. It is a helium-sealed, conventional-magnetic-recording enterprise drive, so it is louder and slower than SSDs and needs vibration-aware mounting in multi-drive systems. Buyers choose it for bulk archival and media storage where sequential throughput matters more than random access.
