The Best External Hard Drives and Portable SSDs of 2019

(Image credit: Tom's Hardware)

An external hard drive or SSD is the do-it-all device of storage. It’s a pocketable device that lets you carry massive files (or lots of small ones) between computers, back up essential data, offload footage from your DSLR or drone while on the go, and more.

But with dozens of models on the market, how do you know which to buy? And should you opt for a faster, more rugged (and more-expensive) external SSD instead instead of a hard drive made up of fragile moving parts? To help you choose the best portable external drive for your needs, we thoroughly test and review key drives and publish our list of specific recommendations on this page.

If you're curious about the kinds of speed and features that will be available with future external drives, check out our stories on USB 3.2 and Everything We Know So Far about USB 4.0, as well as our preview of the kind of performance you can expect from internal PCIe 4.0 drives.

And if none of the drives below seem right for you, we saw a couple of new models from Team Group at Computex 2019. One, the T-Force Treasure, sports RGB lighting, while the PD400 sports a metal shell and IP66 dust and water protection.

Quick Shopping Tips

When shopping for an external drive or SSD, consider the following:

Portable Hard Drive or SSD? Drives that have spinning storage platters inside are very affordable, with 1TB models often selling for under $50 (£40). But they’re also much slower and more fragile than solid-state drives. If you don’t need terabytes of storage and you often travel with your drive, a portable SSD is worth paying extra for. A portable SSD will also be much faster at reading and writing lots of data. But if you need cavernous amounts of external storage, a hard is a better option for most, as multi-terabyte external SSDs sell for several hundred dollars, but 4TB portable hard drives often sell for under $100 (£90).

Don’t Use a Portable Hard Drive as Your Only Backup. Portable hard drives are made up of spinning glass or metal platters, making them a poor choice as a primary backup of your data--especially if you carry them around. Portable SSDs are better here, but you should still keep your irreplacable data backed up on a desktop drive and / or on a cloud service. Because hardware failure is always possible, and portable drives are often small enough to lose or leave behind by accident.

Interface Shorthand

Thunderbolt 3 drives offer the fastest speed, but you won’t be able to use a Thunderbolt 3 drive on a device that doesn’t support Thunderbolt 3, even though it’s the same physical port as USB-C.

USB 3.1 Gen2 is the latest version of this familiar interface, and offers the fastest speed for USB-only devices. But you’ll need devices with USB 3.1 Gen2 ports for maximum speed.

USB 3.0/3.1 Gen1 (effectively the same thing when it comes to bandwidth) is still reasonably fast for external storage (theoretically capable of speeds up to 640MBps), and more than capable of handling hard drive speeds, even in RAID.

Also note that, if you have a spare drive, you can easily make your own portable. Dozens of 2.5-inch drive enclosures can be found online for between $10-$25 (£15-25) that will let you drop in an old drive easily, and turn it into an external hard drive or SSD.

And if you have an M.2 drive that you've swapped out of a laptop or upgraded away from in your desktop, we've recently looked at NVMe enclosures from MyDigitalSSD and Pluggable. If you have a SATA-based M.2 drive that you'd like to turn into a portable drive, Silverstone's MS09 enclosure lets you do just that. And if you're keen on building your own speedy external SSD but don't have a drive handy to use, the recent WD Blue SN500 is a good candidate for that task. It's only available in 256 and 500GB capacities, but it's plenty speedy for external storage, and the more spacious model is already selling for less than $70 at various online outlets. The 250GB model is a tougher sell, with half the capacity and a price that's sticking close to $55 as we wrote this.

Just make sure you get an enclosure that matches your drive, be that SATA or NVMe. And also keep in mind that DIY external drives usually aren't sealed, so they're not as likely to stand up to dust and dampness as well as some external SSDs and portable hard drives that are designed to do so.

The Best Portable SSD

SanDisk Extreme Portable SSD (500GB)

The Best Portable SSD

Capacities: 250GB, 500GB, 1TB, 2TB | Drive Type: SSD | Transfer Protocol: USB 3.1 Gen2 | Sequential Reads: 550 MBps | Warranty: 3 Years

Compact
USB 3.1 Gen 2 to maximize performance
Sleek design with nice styling
USB Type-A and Type-C connectivity
Expensive
No pouch or travel bag
Detachable cable plus adapter

For most users who don't need terabytes of storage, we recommend a portable SSD over a portable hard drive, for both the much-increased durability of solid-state storage, plus generally much-faster speeds.

When it comes to pure transfer performance, the SanDisk Extreme Portable is a tier above many similar models on the market. Pricing is also very competitive with other premium models like the Samsung T5 Portable SSD.

WD My Passport Ultra (4TB)

The Best External Hard Drive

Capacities: 1TB, 2TB, 3TB, 4TB | Drive Type: HDD | Transfer Protocol: USB 3.0 | Sequential Reads: 120MBps | Warranty: 3 Years

Excellent performance for a hard drive
Class-leading pricing
Large 4TB option
Variety of colors
Excellent software package
2TB, 3TB, and 4TB models are slightly thicker

Performance between competing portable hard drives doesn't vary much. In some sense, you can just choose whatever drive from a well-known brand that's on sale or that you like the design or features of. That being said, Western Digital's My Passport Ultra is a very balanced portable hard drive. You get an excellent design backed by class-leading software and good performance for this category. If you want to save a little money, opt for the single color non-Ultra model.

For those looking to spend a little less on an portable hard drive, who also don't need 4TB of storage, should also consider Seagate's Backup Plus Ultra, which features a good software suite AES 256-bit encryption, and USB-A and USB-C support via an adapter.

The Best Rugged Portable Hard Drive

LaCie Rugged RAID Pro (4TB)

The Best Rugged Portable Hard Drive

Capacities: RAID0 | Drive Type: HDD | Transfer Protocols: Thunderbolt 3 , USB 3.1 Gen 1 | Sequential Reads: Depends on configuration | Warranty: 3 Years

Solid sequential performance
Rugged Build
Data recovery service free within the warranty period
Easy-to-use and effective software suite
Expensive
Uses wall power for systems without Thunderbolt 3 / USB 3.1 Gen 2 Type C

While it is on the pricey side, LaCie’s Rugged RAID Pro isn’t too overpriced considering its market placement and the peace of mind of data redundancy. LaCie includes one month of all Adobe apps for free, a $79.49 (£61) value. More importantly, the drive comes with three years of free data recovery protection. That service can (at times) cost thousands of dollars.

If you are a creative professional in the market for an external HDD, be sure to check this drive out. There aren't many competitors: Most other HDD solutions are much larger, and flash-based SSDs don’t yet offer similarly-priced capacity, nor the same value-adds. The LaCie Rugged RAID Pro 4TB has a unique blend of features and accessories that make it easy to use and quite the versatile travel companion.

The Best External Thunderbolt 3 SSD

G-Technology G-Drive mobile Pro SSD (1TB)

The Best External Thunderbolt 3 SSD

Capacities: RAID0 | Drive Type: SSD | Transfer Protocol: Thunderbolt 3 | Sequential Reads: 2,800MBps | Warranty: 5 Years

Sleek aesthetics
Thunderbolt 3 interface
Stunning media file transfer/editing performance
Expensive
Small file transfer performance could be improved
No hardware-based encryption support

G-Technology's G-Drive mobile Pro SSD is pricey, but its peak speed of 2.8GBps can crunch through multi-stream 4K, 8K, and VR media editing with ease. The durable drive is bigger than competitors like Samsung's Portable SSD X5, but the extra bulk helps in cooling, leading to better sustained performance. The G-Drive speeds up workflows, making this Thunderbolt 3 drive particularly attractive for professionals.
