Seagate Hard Drives

Seagate Hard Drives with High-Capacity Storage up to 32TB

Build your storage around what the drive actually needs to do. At Laptop Outlet, our Seagate hard drives cover everyday desktop expansion, NAS storage, CCTV recording, enterprise systems and external backups, giving you a clearer route to the right HDD without treating every high-capacity drive as interchangeable.

Shop Seagate Hard Drives by Capacity & Use

Start with where the drive will be installed, then decide how much capacity you need.

For desktop storage, Seagate BarraCuda gives you internal SATA options for files, media and additional local capacity. For a NAS, move to IronWolf or IronWolf Pro. Recording CCTV footage? SkyHawk and SkyHawk AI are built around surveillance workloads. Exos serves enterprise storage requirements, while Seagate Expansion and Basic give you external USB storage without opening the PC.

That distinction matters. A 6TB desktop HDD, 6TB NAS drive and 6TB surveillance drive may offer the same headline capacity, but they are designed around different operating environments.

Expand Your Desktop Storage with Seagate BarraCuda

Need more room for photos, videos, documents, games or large local files? Seagate BarraCuda is the place to start for compatible desktop storage.

Our BarraCuda options give you 3.5-inch SATA drives across different capacities, so you can add more space without paying for NAS, surveillance or enterprise features your desktop does not need.

Before ordering, check the available 3.5-inch bay, SATA connection and power connector inside your PC. Then look at capacity and price per terabyte to decide whether stepping up to a larger drive gives you better room for future files.

Recording technology can also vary between BarraCuda models and capacities. Seagate's own specifications show both CMR and SMR within the wider BarraCuda family, so check the exact model rather than assuming every BarraCuda is built the same way.

You can also shop our wider range of internal storage drives if you want to compare Seagate with other HDD options.

Choose IronWolf or IronWolf Pro for Your NAS

Building or expanding a NAS? Pick a drive designed for the workload rather than dropping a standard desktop HDD into a multi-drive storage system.

Seagate IronWolf is designed for home, SOHO and small-business NAS environments. Seagate specifies standard IronWolf for systems with 1 to 8 bays, with a workload rate limit of up to 180TB per year.

Move to IronWolf Pro when the NAS, workload or operating environment calls for more. Seagate positions IronWolf Pro for commercial and enterprise NAS use, with a workload limit up to 550TB per year and broader bay support.

Do not buy from capacity alone. Check your NAS manufacturer's compatibility list for the exact drive model and capacity, then evaluate workload rating, warranty and the storage headroom you need.

And remember: RAID is not a separate backup. If the files matter, keep another independent copy rather than relying on the NAS array alone.

Shop SkyHawk Drives for CCTV & Video Recording

For a compatible DVR or NVR, shop a Seagate SkyHawk surveillance drive rather than choosing a desktop HDD purely because the capacity looks right.

SkyHawk is designed around continuous video-recording workloads and supports up to 64 HD camera streams within Seagate's specified operating parameters. SkyHawk AI moves further towards AI-enabled video systems, with support for up to 32 AI streams and a higher stated workload rating.

Go SkyHawk for a compatible conventional surveillance setup. Move to SkyHawk AI when your recorder, analytics workload and system specification can use its additional capabilities.

Storage duration will depend on camera count, resolution, frame rate, codec, recording schedule and retention settings, so avoid buying from a fixed 'days of recording' estimate alone. Check the recorder's supported drive list and calculate capacity around your actual camera setup.

Seagate Exos Storage for Business Systems

Need storage for an enterprise system rather than a standard desktop? Seagate Exos gives you another route.

Our Seagate range includes Exos X24 enterprise storage, designed for workloads and systems where interface support, sustained operation and enterprise specifications matter more than everyday desktop convenience. The Exos X24 family uses CMR and supports high annual workload ratings, with different capacities and interface variants available across Seagate's wider platform.

That does not automatically make an Exos drive the better purchase for a home PC. Check the exact interface, capacity, physical format, controller support and operating requirements first. Buy enterprise storage because the system calls for it, not simply because 'enterprise' sounds like an upgrade.

Add External Backup Storage with Seagate Expansion

Want more storage without opening your computer? A Seagate external hard drive gives you a straightforward USB-connected option for backups, archives and additional file space.

Our range includes Seagate Expansion desktop drives alongside Seagate Basic portable storage. The difference matters.

A portable Basic drive is easier to carry and can suit users who want storage that moves between compatible computers. Expansion Desktop models are larger units designed to stay on a desk and use a separate power adapter alongside the USB connection.

Check the supplied connection, power requirement and operating-system support before ordering. Reformatting may also be required for certain Mac workflows, including Time Machine use on relevant Expansion Desktop models.

Compare Capacity, Compatibility & Total Cost

More terabytes can improve the price per terabyte, but only when the drive actually suits the system.

Start by estimating how much storage you use now and how quickly it is growing. A larger HDD can make sense when media libraries, backups, surveillance footage or NAS data are expanding steadily, while buying capacity you are unlikely to use may simply increase the initial spend.

• Physical format: confirm the PC, NAS or recorder has the right drive bay and mounting space.
• Interface: internal models commonly use SATA, while our external Seagate drives connect over USB.
• Supported capacity: make sure the host system recognises the size you intend to install.
• Workload: match desktop, NAS, surveillance or enterprise storage to its intended environment.
• Warranty: check the cover shown for the exact model rather than applying one warranty period across every Seagate family.
• Recovery services: eligibility for Seagate Rescue Data Recovery Services varies by drive family and model.

If capacity per pound matters more than loading speed, an HDD can be attractive for bulk storage. If faster access is the priority, compare SSD alternatives before deciding where your budget is better spent.
