Buy the WD Elements Portable 6TB: sold by Amazon, bus-powered, and the most capacity WD offers in a drive that runs from its USB cable. If the drive will never leave your desk and you want more space in one box, the 8TB or 10TB WD Elements Desktop holds more.
The best external hard drives for backing up a home office in 2026 - from the WD Elements Portable 6TB, sold by Amazon and powered by its USB cable, to the 10TB WD Elements Desktop for the most space in one drive. Spinning drives for bulk backup, not fast working storage.

Unbranded 'portable 16TB' drives at implausibly low prices — No manufacturer currently ships a 16TB drive in a 2.5-inch bus-powered enclosure - WD describes its 6TB My Passport as the world's first 6TB drive in that form factor. Listings advertising far larger portable capacities cheaply are typically small drives with firmware reporting a false size, which appear to work until the point where data is silently discarded. Buy capacities that the major manufacturers actually publish.
1The most capacity you can carry on one USB cable: 6TB in a 2.5-inch bus-powered drive, sold and shipped by Amazon. It has no encryption, password protection or bundled backup software, so pair it with the backup tool built into your operating system or one you already trust.
3The plain, long-running desktop drive for people who just want the most storage for the money. Ten terabytes over USB 3.0 with an AC adapter is the whole feature list; it is a bulk-archive and backup target rather than a daily working drive, and the Micro-B connector shows its age.
4The most storage in one drive on this page: 8TB, a third more than the largest portable, for a backup target that lives beside the desk. It needs a mains socket and has no encryption or bundled backup software, and at our October 2026 price check it cost a few dollars more per terabyte than the 6TB WD Elements Portable - buy it for the capacity, not as the cheap option.
5The entry point. 4TB is more than enough to hold a full versioned backup of a typical work laptop several times over, and this is the cheapest way to get there from a manufacturer with a real warranty operation.

Our WFH Score for storage weights cost per terabyte at the Amazon price when each drive was scored at 30 points, backup fitness (encryption and bundled software) at 25, desk practicality (bus power, cabling) at 20, portability and build at 15, and warranty or recovery service at 10. It is scored from published specifications and current prices, not from transfer benchmarks or failure testing, neither of which we run. Drive prices move faster than scores do, so check the live price on each card before you buy.
The consistent advice in r/DataHoarder and r/backup is that the drive matters far less than having more than one copy of anything you cannot recreate. The widely repeated shorthand is 3-2-1: three copies, on two kinds of media, one of them off-site. Within the drive choice itself, the recurring points are that desktop 3.5-inch drives are better value than portables for anything that stays put, that shucking external drives for the mechanism inside is common but voids warranties, and that a drive with no second copy behind it is not a backup strategy at all.
Popular options we evaluated and passed on, with the specific reason each one fell short of our top picks.
At our October 2026 check the only buy box was a third-party reseller about 50% over WD's list price. We will re-list it if WD or Amazon returns as seller.

An external hard drive and an external SSD solve different problems, and buying the wrong one is the most common mistake in this category. An SSD is fast working storage - the disk you edit video from or run a project off. A hard drive is cheap bulk capacity, and its job is backup: the second copy that exists so a laptop failure is an inconvenience rather than a catastrophe. If you want speed, buy an SSD. If you want terabytes per dollar, buy what is on this page.
The first decision is portable versus desktop, and it is really a decision about power. A 2.5-inch portable drive runs from the USB cable alone - one cable, no adapter, goes in a bag. A 3.5-inch desktop drive needs a mains socket, but it holds more in one box: the WD Elements Desktop on this page is 8TB, a third more than the largest portable. Desktop drives have usually been the cheaper terabyte too, but at our October 2026 price check the 6TB WD Elements Portable came out cheaper per terabyte than the 8TB desktop drive, so do the sum on the day you buy.
The second decision is whether you need encryption. A backup drive holds a complete copy of your working life, and it is the single easiest thing in a home office to lose or have stolen. Drives with hardware encryption and password protection - WD's My Passport line, for example - cost a little more for a feature you will use exactly once, on the day it matters. For anyone handling client data under a contract, treat it as mandatory rather than optional.
A note on what we do not claim: we research these drives from manufacturer specifications and published documentation. We do not run sustained transfer benchmarks or failure testing, so where a speed or capacity figure is the manufacturer's, this page attributes it. Drive reliability in particular cannot be honestly assessed from a spec sheet - Backblaze's published failure statistics are the only large-scale public dataset worth consulting, and it is linked below.
