External storage for a Mac should connect over USB-C and be formatted for macOS or exFAT. Every pick offers 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

YOTUO 1TB Portable External Hard Drive

Lowest Price Here1 of 5

YOTUO 1TB Portable External Hard Drive on Amazon (opens in a new tab)

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 in the build.

Skip if

The maker gives no rated read speed, so look elsewhere if that figure decides it for you.

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 SanDisk Portable on capacity (1TB). A USB 3.0 and USB-C connection is unique to it among these picks, while the SanDisk Portable uses a USB-C 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. Buyers who need a confirmed rated read speed should compare it with the GARMESE, which offers 2,000MB/s.

Key dimensions & specs

  • Drive type: HDD
  • Capacity (as reviewed): 1TB
  • Connection: USB 3.0 and USB-C
  • Durability claim: Silicone sleeve
  • Security: None stated

Pros

  • Both USB 3.0 and USB-C connections
  • Silicone sleeve
  • 0.16kg weight
  • Capacity of 1TB, ahead of the SSK 500GB

SSK Portable SSD 500GB

Also Consider2 of 5

SSK Portable SSD 500GB on Amazon (opens in a new tab)

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. On capacity it trails the group at 0.5TB, while the Rugged USB-C is rated for 2TB. On rated read speed it sits mid-pack at 1,050MB/s: the GARMESE offers 2,000MB/s, and the SanDisk Portable comes in at 1,000MB/s.

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. Capacity is its weakest area, and the Rugged USB-C covers it better at 2TB.

Key dimensions & specs

  • Drive type: SSD
  • Capacity (as reviewed): 0.5TB
  • Max read speed: 1,050MB/s
  • Connection: USB 3.2 Gen 2 (USB-C and USB-A cables)

Largest Capacity3 of 5

LaCie Rugged USB-C 2TB Portable Hard Drive on Amazon (opens in a new tab)

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

Pass if a published rated read speed matters; this one has none.

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. There is no published rated read speed figure, whereas the GARMESE offers 2,000MB/s.

Key dimensions & specs

  • Drive type: HDD
  • Capacity (as reviewed): 2TB

GARMESE's SSD offers 2,000MB/s reads in a 33g body with a keychain hole.

Best for

Buyers who put rated read speed first.

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 matches the YOTUO 1TB and the SanDisk Portable on capacity (1TB). On rated read speed it leads this guide at 2,000MB/s, ahead of the SSK 500GB (1,050MB/s). 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 SanDisk Portable, at the time of writing.

How We Chose

Each pick was assessed across 4 criteria weighted for real-world use.

Connection
We checked the USB standard and connector each maker names.
Security and extras
We checked for password protection, encryption and backup software.
Durability
We noted listed drop, water and dust claims.
Drive type and speed
We recorded whether each drive is an SSD or hard drive and its read speed.

What to Look for in an External Storage for Mac

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

  1. How much capacity you need

    Among these picks, capacity runs from 0.5TB on the SSK 500GB to 2TB on the Rugged USB-C. Pick the lowest figure that covers your use; the extra usually costs more than it returns.

  2. Match the port

    A 1,050MB/s SSD needs USB 3.2 Gen 2 (10Gbps); a 2,000MB/s SSD needs Gen 2x2 (20Gbps), which few laptops and no Macs offer. On a slower port the drive simply runs at the port's speed.

  3. Mac and Windows formatting

    Many drives ship formatted for Windows. On a Mac, reformat to APFS for Time Machine, or exFAT to share the drive with a Windows PC.

  4. Password and encryption

    Hardware encryption with a password protects a drive that could be lost. Software-only encryption depends on an app being available on each computer.

  5. SSD or hard drive

    A portable hard drive gives the most terabytes per dollar and suits backups. A portable SSD is several times faster, lighter and more tolerant of drops, which suits working files and games.

Frequently Asked Questions

How do these external drives compare on rated read speed?

The GARMESE, at 2,000MB/s. The SSK 500GB follows at 1,050MB/s, while the SanDisk Portable has 1,000MB/s.

Which is the cheapest pick in this guide?

The YOTUO 1TB cost the least when we checked, and the SanDisk Portable sat at the top of the range. Prices move often, so check the current listing before buying.

Why does my 1TB drive show less space?

Drive makers count 1TB as one trillion bytes; Windows counts in binary units, so it shows about 931GB. No space is missing.

Is a portable SSD good for backups?

It works, but a hard drive gives more capacity per dollar for backups. Keep a second copy somewhere else for anything irreplaceable.

Does the cable matter?

Yes. Use the included cable or one rated for the drive's speed; a charging-only or USB 2.0 cable limits transfers.

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 the fastest rated read speed here (2,000MB/s) if those matter more to you.
