Largest desktop hard drive ever breaks another record; 28TB Seagate Expansion desktop hard drive has lowest Terabyte cost I’ve seen in 2025

• STKP28000400 is a 28TB desktop hard drive from Seagate’s popular Expansion family
• It includes Seagate’s Data rescue service should the drive fail to work
• Despite its massive capacity, it still features the now-obsolete USB-A port

Best Buy has listed the Seagate STKP28000400 desktop hard drive as part of its well-known Expansion series, featuring an impressive 28TB capacity.

The size of this drive is noteworthy, and though it does support the slightly retrograde USB-A interface, it should be enough for most use cases, ensuring hardware cross-compatibility and high transfer speeds. It is a shame though that there’s no plan to have a Type-C connector that wouldn’t require a separate power connector.

Built-in data recovery support

The STKP28000400 includes Seagate’s Rescue Data Recovery Services, offering users an extra layer of security by assisting in recovering data if the drive encounters issues.

Priced at $389.99, the STKP28000400 is currently available from Best Buy and Provantage on preorder. It provides one of the lowest per-terabyte ratios on the market, costing about $14.22 per TB. HDDs from its rivals like the WD Red Pro (24TB) cost $23.75 per TB while the WD My Passport 6TB HDD costs $24.99 per TB.

Seagate has a long history of releasing large-capacity hard drives, and recently unveiled the Exos M, the world’s largest hard drive with a 32TB capacity.

Desktop hard drives are often cheaper than internal HDD at the same capacity and that’s because of economies of scale. A lot of DIYer have resorted to shucking external HDDs in order to extract hard drives and use them in NAS devices.
