How we chose these desktop external hard drives
The best desktop external hard drive for you depends on the amount of data you need to store, your computer's ports, power access and the features you want. We compared those details across eight desktop options for common home uses, from keeping another copy of family photos to expanding a Windows PC's storage.
Seagate Expansion drives suit buyers who want to connect a drive and save files without installing setup software. WD Elements focuses on capacity and straightforward Windows PC use, while WD My Book adds password protection, hardware encryption and downloadable backup software.
Power is another practical difference. Most models here come with a power adapter, while Seagate One Touch uses bus-powered USB-C and does not require a wall outlet.
Every product below is a mechanical hard drive. That makes this group a fit for large libraries and scheduled backups that can stay near a computer, while an external SSD is a better direction if you need a compact drive for frequent travel or fast access.

Choose it for basic PC expansion at 6TB. Skip it if you need a drive for a USB-C-only computer or want security software built into your storage choice; our PC external hard drive guide covers more computer-focused options.
How do you choose a desktop external hard drive?
Choose by matching capacity, connection, format, power and security to how you plan to use the drive. Start with the files you actually want to copy, then check the computer and desk where the drive will stay.
How much space should the best desktop external hard drive have?
Pick 4TB for a smaller collection, 6TB for a larger home archive, or 8TB if you keep substantial photo, video or media folders. The right size leaves room for future backups without making you reorganize the drive every few months.
Make a rough inventory of documents, photos, videos, music and computer backups. If you already own a drive, check its used space and consider how quickly it fills; don't assume the full labeled capacity will be available for files after formatting.
For a second backup of selected folders, you may need less space than you would for a full computer image plus a media archive. See our guide to choosing an external hard drive size to estimate your needs.
Which connection and format fit your computer?
Check the ports on your computer and the drive's format before the first file transfer. USB 3.0 is used by most of these options, and several also work with USB 2.0 devices.
USB-C can simplify the cable setup if your computer has a suitable port, as with the Seagate One Touch. If the computer only has USB-A, confirm the connection you need before buying rather than assuming every cable or adapter is included.
The file system matters, too. Seagate Expansion models recognize Windows and Mac computers, but Time Machine requires reformatting.
WD Elements is formatted as NTFS for Windows, so Mac users should check whether reformatting is needed for their intended workflow.
Does a desktop hard drive need an outlet?
Most desktop hard drives need a separate power adapter and a nearby outlet. Seagate One Touch is the exception in this group because it uses bus-powered USB-C and doesn't need a wall outlet.
A desktop drive also needs a stable surface and space for its enclosure and cables. Measure the shelf or desk area, then leave a little clearance so the cable isn't sharply bent or pulled when you move other equipment.
If you need storage you can carry with a laptop, a portable drive or external SSD may be a better fit. For more detail, see whether an external hard drive needs its own power.
Do you need encryption or backup software?
Choose WD My Book if you want password protection and 256-bit AES hardware encryption. Its backup software requires a download and installation, so allow time to configure it rather than expecting a finished backup routine the moment you connect the drive.
If you only need extra space for folders you manage yourself, a Seagate Expansion or WD Elements can keep the workflow simple. A drive's capacity is not a backup plan by itself: decide which folders to copy, how often to update them and where to keep a second copy.
How should you set up and care for a desktop drive?
Set up a new drive by placing it securely, connecting it to the computer, checking its format and making a small test copy before moving a large archive. A few careful steps make it easier to spot a connection or compatibility issue early.
What should you do on the first connection?
Set the drive on a stable, ventilated surface near the computer and outlet. Connect the power adapter when the model needs one, then connect the USB cable directly to the computer if possible.
Open the drive on your computer and confirm that it appears with the expected capacity. Before copying a large folder, save a few noncritical files, open them from the drive and make sure the transfer completed.
If you plan to use Time Machine, check the format and reformat the compatible Seagate Expansion drive before using it for that purpose. Reformatting erases existing contents, so do this before storing files on the drive.
How should you organize backups?
Keep the drive's folders easy to recognize, such as separate folders for photos, documents and annual computer backups. Use a clear date in backup folder names when you make manual copies, so you can tell which copy is newest.
A desktop drive is useful as one local copy, but it should not be the only home for important files. Keep another copy on a separate drive or in cloud storage, especially for family photos, work files and documents that would be hard to replace.
How can you reduce avoidable drive problems?
Keep the drive on a steady surface and avoid moving it while files are copying. Don't pull the USB cable to disconnect it during a transfer, and use the computer's safe eject option before unplugging the drive.
Protect the power and USB cables from being pinched under furniture or pulled by foot traffic. If the drive is making unusual clicking sounds, disconnect it only after safe ejection if possible, and avoid repeated attempts to copy irreplaceable files.
For more detail, see our guide to safely ejecting an external hard drive on a PC or Mac and the signs that an external hard drive may be failing.
What mistakes should you avoid with desktop hard drives?
The most common mistakes are buying too little space, overlooking the power requirement, assuming every computer can use the drive's format and treating one drive as a complete backup plan. Checking those four details before purchase can prevent extra setup and missing files later.
Don't choose solely by the biggest capacity number. If you only need a second copy of documents and a small photo library, 4TB may be more appropriate than 8TB; if you already keep large video folders, a smaller drive can fill quickly.
Don't assume that USB-C means every computer is compatible or that a drive with an included cable fits every port. Confirm the port on your computer and the cable connection before ordering, especially for the One Touch model.
Don't format a drive after you have copied files you want to keep. Reformatting can erase stored data, so decide on the computer and backup software first, then format before the main transfer.
Finally, don't leave your only copy of important files on a single external drive. A second copy stored separately gives you another way to recover if the drive or the computer becomes unavailable.
Which best desktop external hard drive should you choose?
Choose the Seagate Expansion Desktop 6TB for a straightforward home backup, WD My Book 8TB for password-protected capacity, or Seagate One Touch 8TB if bus-powered USB-C fits your computer and desk. Pick the 4TB Expansion for a moderate collection, and choose WD Elements for simple Windows PC expansion.
Before you buy, match the capacity to your files, confirm the port and format, and make sure the drive's power setup suits its location. For a local copy that is part of a longer backup plan, see our guide to external hard drives for long-term backup and keep a second copy of your most important files elsewhere.

Read our guide to whether an external hard drive needs power before choosing a spot for your drive.
Is 6TB or 8TB better for a desktop external hard drive?
Choose 6TB if it covers your current files and leaves room for the next backup cycle. Choose 8TB if you store large photo, video or media folders or want more room before managing old files.
Our guide to choosing an external hard drive size can help estimate your needs.
Can I use a desktop external hard drive with a Mac?
Many desktop drives connect over USB, but file-system format can affect how you use them. Seagate Expansion drives recognize Mac computers, and reformatting is required to use them with Time Machine.
Check your Mac's ports and the drive's format before moving files.
Is a desktop hard drive good for long-term backup?
A desktop hard drive can hold a large local backup, but one drive should not be your only copy of important files. Keep another copy in a separate place, such as another drive or a cloud service.
