The Best External SSDs
Five external SSDs compared by interface, rated read speed and durability, so you can match a drive to the ports your computer has.
By Alex Morgan, PC Hardware Editor
12 min read5 products evaluated

An external SSD's rated speed depends on the port it plugs into. A 10Gbps USB port tops out around 1,050MB/s, a 20Gbps Gen 2x2 port around 2,000MB/s, and only USB4 or Thunderbolt reaches the 4,000MB/s class.
We researched five portable SSDs across those three tiers using their Amazon listings and prices at the time of writing. We did not test them; speeds are manufacturer maximums.

Our Picks
Best All-Round1 of 5
Crucial X10 Pro Portable SSD 2TB
Crucial's X10 Pro offers 2,100MB/s reads and 2,000MB/s writes, so large exports copy back nearly as fast as they read.
Best for
- Creators who move large files daily
Skip if
- If budget leads, the One Touch SSD 2TB was cheaper at our last price check.
Why we like it
It adds IP55 water and dust resistance, a 7.5ft drop rating and password protection built into the drive. It reads at up to 2,100MB/s and is rated IP55 with 7.5-foot drop resistance. Full speed needs a 20Gbps USB port.
On capacity it ties with the T9 2TB, the T7 Shield 2TB and the One Touch SSD 2TB at 2TB. On rated read speed it sits mid-pack at 2,100MB/s: the Rugged SSD4 offers 4,000MB/s, and the One Touch SSD 2TB comes in at 1,030MB/s. You get an SSD password protection security here, which sets it apart from the Rugged SSD4 and its a none stated security. You also get a lanyard loop and activity light and three months of Mylio Photos+ and Acronis True Image.

Best for Long Transfers2 of 5
Samsung T9 Portable SSD 2TB
Samsung's T9 lists sustained read and write speeds up to 2,000MB/s, and Samsung's Dynamic Thermal Guard is meant to hold that pace through long copies.
Best for
- Video projects on a 20Gbps port
Skip if
- Price-first buyers should look at the One Touch SSD 2TB, which cost less when we checked.
Why we like it
Magician software handles firmware updates, health monitoring and optional encryption. On capacity it ties with the X10 Pro 2TB, the T7 Shield 2TB and the One Touch SSD 2TB at 2TB. On rated read speed it sits mid-pack at 2,000MB/s: the Rugged SSD4 offers 4,000MB/s, and the One Touch SSD 2TB comes in at 1,030MB/s.
It is the only pick here with a USB 3.2 Gen 2x2 connection; the T7 Shield 2TB has a USB 3.2 Gen 2 connection instead. It also offers support for iPhone 15 Pro ProRes 4K60 recording. Its top speed needs a USB 3.2 Gen 2x2 (20Gbps) port; most laptops and all Macs run it at 10Gbps speeds instead. It was priced above the X10 Pro 2TB and below the Rugged SSD4 at the time of writing.

Fastest Listed Speeds3 of 5
LaCie Rugged SSD4 1TB
LaCie's Rugged SSD4 uses a 40Gbps USB connection and offers 4,000MB/s reads and 3,800MB/s writes, the fastest figures here.
Best for
- USB4 and Thunderbolt computers
Skip if
- Skip it if capacity matters most to you; the X10 Pro 2TB offers 2TB.
Why we like it
It is the only 1TB drive in this guide, and it needs a USB4 or Thunderbolt port to reach those speeds. It reads at up to 4,000MB/s over USB 40Gbps and Thunderbolt, and it is IP54-rated with 3-metre drop and 1-ton crush resistance. It suits fieldwork with large video files.
Its 1TB capacity is the smallest in this group; the X10 Pro 2TB leads at 2TB. Nothing else here matches its 4,000MB/s rated read speed; the X10 Pro 2TB comes closest at 2,100MB/s. Like the T7 Shield 2TB and One Touch SSD 2TB, it has a none stated security, while the X10 Pro 2TB uses an SSD password protection security.
It also comes with compatibility with Thunderbolt 3, 4 and 5 as well as 5-20Gbps USB and a three-year warranty with Rescue data recovery. Its price falls between the T9 2TB and the T7 Shield 2TB, based on our last check.

- Three-year warranty with Rescue data recovery
Cons
- Capacity trails the X10 Pro 2TB (2TB)

Best Rugged 10Gbps4 of 5
Samsung T7 Shield Portable SSD 2TB
Samsung's T7 Shield runs at 10Gbps USB speeds, rated to 1,050MB/s reads, a speed that many laptop USB-C ports support.
Best for
- Travel and fieldwork
Skip if
- If budget leads, the One Touch SSD 2TB was cheaper at our last price check.
Why we like it
Its IP65 rating and 9.8ft drop protection suit a drive that lives in a camera bag. It uses an internal PCIe NVMe drive for reads up to 1,050MB/s and writes up to 1,000MB/s over USB 3.2 Gen 2. The rubber shell adds water, dust and drop resistance.
It matches the X10 Pro 2TB, the T9 2TB and the One Touch SSD 2TB on capacity (2TB). Its 1,050MB/s rated read speed ranks fourth of 5 here, behind the Rugged SSD4 (4,000MB/s) and ahead of the One Touch SSD 2TB (1,030MB/s). You get a USB 3.2 Gen 2 connection here, which sets it apart from the One Touch SSD 2TB and its a USB 3 (as listed) connection. It was the highest-priced of the 5 picks at the time of writing, so the case for it rests on what it adds over the Rugged SSD4 and the rest.

Seagate One Touch SSD 2TB
Seagate's One Touch SSD wraps a 2TB drive rated to 1,030MB/s in a light textile cover.
Best for
- Everyday laptop storage
Skip if
- Skip it if rated read speed matters most to you; the Rugged SSD4 offers 4,000MB/s.
Why we like it
It was the lowest-priced drive here at the time of writing and carries a three-year warranty with Rescue data recovery. On capacity it ties with the X10 Pro 2TB, the T9 2TB and the T7 Shield 2TB at 2TB. On rated read speed it trails the group at 1,030MB/s, while the Rugged SSD4 offers 4,000MB/s.
No other pick in this guide offers a USB 3 (as listed) connection; compare the T9 2TB, which has a USB 3.2 Gen 2x2 connection. It shares a none stated security with the Rugged SSD4 and T7 Shield 2TB; the X10 Pro 2TB goes with an SSD password protection security. It also offers a lightweight textile-covered design and a six-month Mylio Photos+ subscription and a Dropbox Backup trial. No other pick here cost less at our last price check, and the X10 Pro 2TB was closest.

How We Chose These External SSDs
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.

- How these picks were ranked
- We set side by side five drives on drive type, capacity, rated read speed and connection as the makers state them. Nothing was tested in-house; 5 of the 6 fields compared are stated for every pick, while durability claim has gaps.
- The shared baseline
- All 5, from the X10 Pro 2TB to the One Touch SSD 2TB, state drive type, capacity and rated read speed.
- Where the specs have gaps
- The T9 2TB and the One Touch SSD 2TB give no durability claim.
- Price range
- From the One Touch SSD 2TB to the T7 Shield 2TB, all sat in the $250 to $500 tier when we checked.
