Five external drives ranked on capacity and drive type; the YOTUO 1TB is the cheapest route in.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated

Time Machine works with any external drive you format for it; a hard drive gives the most space for the money. Every pick is a hard drive.
The order reflects drive type, capacity (as reviewed) and connection from maker specifications; gaps in the specs are flagged, not filled in rather than guess, since we have not benched them.

Lowest Price Here1 of 5
YOTUO 1TB Portable External Hard Drive
YOTUO's 1TB drive ships with both USB 3.0 and USB-C connections and a silicone sleeve.
Best for
- Buyers who would rather put the savings elsewhere than into the Expansion 1TB.
Skip if
- Pass on it if capacity of 1TB, behind the ADATA HD710 Pro 2TB (2TB) rules it out for your setup.
Why we like it
It weighs 0.16kg. It stores and plays PS4 and Xbox One games directly, and a silicone sleeve cushions drops. It works with Windows, Mac and Linux.
It matches the Expansion 1TB and the Seagate Portable 1TB on capacity (1TB). As a spinning hard drive it is slower than an SSD and less tolerant of knocks while running. The nearest alternative on capacity is the ADATA HD710 Pro 2TB at 2TB, against 1TB here.
It makes the most sense for buyers who would rather put the savings elsewhere than into the Expansion 1TB, since it offers undercutting the Expansion 1TB on price when we checked. It was the cheapest of the group when we checked; the Expansion 1TB was the next step up.

Also Consider2 of 5
Seagate Expansion Portable 1TB External Hard Drive
The Expansion Portable is Seagate's simplest drive: a 1TB USB 3.0 hard drive with no extras.
Best for
- Buyers who want plain plug-in design.
Skip if
- Skip it if price comes first: the YOTUO 1TB cost less when we checked.
Why we like it
It suits a single backup job. As a spinning hard drive it is slower than an SSD, but it costs less per terabyte for backups. It needs no power adapter and draws power over USB.
It shares a USB 3.0 connection with the ADATA HD710 Pro 2TB and My Passport 2TB; the Seagate Portable 1TB goes with a USB 3.0 (USB-A) connection. It also comes with a plain plug-in design, USB 3.0 and a compact enclosure. It connects by USB-A; a USB-C-only laptop such as a MacBook Air needs an adapter or a USB-C cable. On price it sat second of 5, between the cheaper YOTUO 1TB and the pricier Seagate Portable 1TB, at the time of writing.

Strong Alternative3 of 5
Seagate Portable 1TB External Hard Drive
The 1TB Seagate Portable lists PC, Mac, PlayStation and Xbox support and a year of Rescue data recovery.
Best for
- Buyers who want PC, Mac, PlayStation and Xbox compatibility.
Skip if
- Skip it if capacity matters most to you; the ADATA HD710 Pro 2TB offers 2TB.
Why we like it
Mac users reformat it first. On capacity it ties with the YOTUO 1TB and the Expansion 1TB at 1TB. No other pick in this guide offers a USB 3.0 (USB-A) connection; compare the ADATA HD710 Pro 2TB, which has a USB 3.0 connection.
It also offers the lowest price tier among Seagate drives here. It connects by USB-A; a USB-C-only laptop such as a MacBook Air needs an adapter or a USB-C cable. It ships formatted for Windows, so a Mac user reformats it (exFAT for both systems, APFS for Time Machine).
As a spinning hard drive it is slower than an SSD and less tolerant of knocks while running. When we checked, only the Expansion 1TB and cheaper picks cost less, and the ADATA HD710 Pro 2TB cost more.

How We Chose These Hard Drives for Time Machine Backup
Alex Morgan compared the manufacturer specifications, connectivity, warranty terms and compatibility of every pick. Figures come from the makers unless a third-party source is named; we did not test these products ourselves.

- The figures behind the order
- We set side by side five drives on drive type, capacity, connection and durability claim, using each maker's published specs. We did not test them in-house, and durability claim is missing for at least one pick.
- What every pick has in common
- All 5, from the YOTUO 1TB to the My Passport 2TB, state drive type, capacity and connection.
- Where the specs have gaps
- The Expansion 1TB, the Seagate Portable 1TB and the My Passport 2TB give no durability claim.
- Price range
- At our last check the picks ran from the YOTUO 1TB ($50 to $100) to the My Passport 2TB ($100 to $150).
