Five external drives ranked on capacity and rated read speed, where the Rugged USB-C has the largest capacity; the YOTUO 1TB is the cheapest route in.

12 min read5 products evaluated

External storage for a Mac should connect over USB-C and be formatted for macOS or exFAT. Every pick has a USB-C connection.
We ranked these external drives on drive type, capacity (as reviewed) and max read speed using manufacturer specifications; where a maker leaves out max read speed, we say so rather than guess, since we have not benched them.

Our Picks
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 SSK 500GB.
Skip if
- Worth skipping when capacity of 1TB, behind the Rugged USB-C (2TB) is a problem.
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 GARMESE and the PNY RP60 1TB on capacity (1TB). A USB 3.0 and USB-C connection is unique to it among these picks, while the PNY RP60 1TB uses a USB 3.2 Gen 2x2 (20Gbps) connection. It is the only pick here with a silicone sleeve durability claim; the GARMESE has a shock resistant durability claim instead.
As a spinning hard drive it is slower than an SSD and less tolerant of knocks while running. It was the cheapest of the group when we checked; the SSK 500GB was the next step up.

- 0.16kg weight
- Capacity of 1TB, ahead of the SSK 500GB

The catch

Also Consider2 of 5
SSK Portable SSD 500GB
SSK's 500GB SSD ships with both USB-C and USB-A cables and offers 1,050MB/s reads.
Best for
- Buyers who want both USB-C and USB-A cables.
Skip if
- Skip it if capacity matters most to you; the Rugged USB-C offers 2TB.
Why we like it
It is the cheapest SSD here. It reads at up to 1,050MB/s over a 10Gbps USB-C link, fast enough for moving large project folders. Expect about 465GB to show in Windows, which is normal for a 500GB drive.
SLC caching keeps large transfers fast, and S.M.A.R.T. and TRIM support help it last. It reads at up to 1050MB/s and writes at up to 1000MB/s over 10Gbps USB. S.M.A.R.T. health reporting and TRIM help keep write speeds consistent over time.
On capacity it trails the group at 0.5TB, while the Rugged USB-C is rated for 2TB. It also offers an activity LED and an SLC cache for steady transfers. When we checked, only the YOTUO 1TB cost less, and the Rugged USB-C cost more.

Largest Capacity3 of 5
LaCie Rugged USB-C 2TB Portable Hard Drive
The LaCie Rugged USB-C puts a native USB-C connector on a 2TB drive rated against drops, dust and rain.
Best for
- Buyers who put capacity first.
Skip if
- Skip it if price comes first: the YOTUO 1TB cost less when we checked.
Why we like it
It suits a MacBook without adapters. The LaCie Rugged shell is built to survive drops, dust and rain, which suits carrying footage between sites. It connects over USB-C and works with USB 3.0 ports on older machines.
On capacity it leads this guide at 2TB, ahead of the YOTUO 1TB (1TB). It is the only pick here with a USB-C (USB 3.0 compatible) connection; the YOTUO 1TB has a USB 3.0 and USB-C connection instead. It also offers Mac and PC compatibility.
As a spinning hard drive it is slower than an SSD and less tolerant of knocks while running. It was priced above the SSK 500GB and below the GARMESE at the time of writing.

Strong Alternative4 of 5
GARMESE 1TB External SSD
GARMESE's SSD offers 2,000MB/s reads in a 33g body with a keychain hole.
Best for
- Buyers who want 33g body with a keychain hole.
Skip if
- If budget leads, the YOTUO 1TB was cheaper at our last price check.
Why we like it
A USB-A adapter is included. It reads at up to 2,000MB/s over USB 3.2 Gen 2x2, which is twice a standard 10Gbps drive. Full speed needs a 20Gbps port.
It uses USB 3.2 Gen 2x2 for reads up to 2000MB/s and writes up to 1800MB/s, which needs a 20Gbps port. It matches the YOTUO 1TB and the PNY RP60 1TB on capacity (1TB). No other pick in this guide offers a shock resistant durability claim; compare the YOTUO 1TB, which has a silicone sleeve durability claim.
It also comes with 1,800MB/s rated writes. Its top speed needs a USB 3.2 Gen 2x2 (20Gbps) port; most laptops and all Macs run it at 10Gbps speeds instead. On price it sat fourth of 5, between the cheaper Rugged USB-C and the pricier PNY RP60 1TB, at the time of writing.

Skip if
- Skip it if price comes first: the YOTUO 1TB cost less when we checked.
Why we like it
It also is rated for 1TB. It matches the YOTUO 1TB and the GARMESE on capacity (1TB). It is the only pick here with an IP65 durability claim; the YOTUO 1TB has a silicone sleeve durability claim instead.
Its top speed needs a USB 3.2 Gen 2x2 (20Gbps) port; most laptops and all Macs run it at 10Gbps speeds instead. Another plus: capacity of 1TB, ahead of the SSK 500GB. It was the most expensive pick when we checked, so weigh what it adds over the GARMESE. Buyers who need a confirmed rated read speed should compare it with the GARMESE, which offers 2,000MB/s.

How We Chose
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 lined up five drives on drive type, capacity, rated read speed and connection as the makers state them. These are research figures, not bench results: 3 of 5 picks leave out rated read speed.
- What every pick has in common
- All 5, from the YOTUO 1TB to the PNY RP60 1TB, state drive type, capacity and connection and share None stated security.
- Where the specs have gaps
- The YOTUO 1TB, the Rugged USB-C and the PNY RP60 1TB give no rated read speed; the SSK 500GB gives no durability claim.
- Price range
- At our last check the picks ran from the YOTUO 1TB ($50 to $100) to the PNY RP60 1TB ($150 to $250).
