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.
YOTUO 1TB Portable External Hard Drive

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.

  • Capacity of 1TB, ahead of the SSK 500GB

Cons

  • Capacity of 1TB, behind the Rugged USB-C (2TB)

The catch

Buyers who need a confirmed rated read speed should compare it with the GARMESE, which offers 2,000MB/s.

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.
SSK Portable SSD 500GB

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.

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.
LaCie Rugged USB-C 2TB Portable Hard Drive

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.
GARMESE 1TB External SSD

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.

Premium Pick5 of 5

PNY RP60 1TB

The PNY RP60 1TB stands out for a USB 3.2 Gen 2x2 (20Gbps) connection.

Best for

Buyers who want a USB 3.2 Gen 2x2 (20Gbps) connection and can spend more than the GARMESE costs.

Skip if

Skip it if price comes first: the YOTUO 1TB cost less when we checked.
PNY RP60 1TB

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.

What to Look for in an External Storage for Mac

Key buying criteria so you get the right fit the first time.

Frequently Asked Questions

How does the YOTUO 1TB compare with the Rugged USB-C on capacity?

Which has the fastest rated read speed: the GARMESE or the SSK 500GB?

The GARMESE tops rated read speed at 2,000MB/s; the SSK 500GB follows at 1,050MB/s, 90% apart. The YOTUO 1TB, the Rugged USB-C and the PNY RP60 1TB don't state a rated read speed figure, so they sit outside this comparison; 2 of 5 picks are ranked.

Why is the Rugged USB-C our Largest Capacity pick?

The label rests on the largest capacity here (2TB). On capacity it leads the YOTUO 1TB, 2TB against 1TB, a 100% margin. The YOTUO 1TB, the cheapest pick, sat in the $50 to $100 tier against $100 to $150 here, without out-ranking it on any listed spec. It makes sense for anyone who puts capacity first.

Bottom Line

Our first pick is the YOTUO 1TB, chosen for undercutting the SSK 500GB on price when we checked. Look at the SSK 500GB for both USB-C and USB-A cables, the Rugged USB-C for the largest capacity here (2TB) and the GARMESE for a 33g body with a keychain hole if those matter more to you.
