Since 1982, PCMag has tested and rated thousands of products to help you lot make meliorate buying decisions. (Run into how we test.)
If yous need speedy local storage for lots of files (say, music or movies you carry around, or all those pics and videos you collect on your phone or photographic camera), you may want to consider a portable solid-state drive (SSD) rather than a portable hard drive.
In one case prohibitively expensive, SSDs of all stripes have been falling in price over the past few years, and external SSDs have emerged as alternatives to external difficult drives, delivering as much as five times the speed and much greater durability. They take no metal platters to spin upwardly, nor any read/write heads that need to travel to a specific point on a platter to detect the file yous need. And because of their lack of moving parts, portable SSDs are unremarkably more compact, slimmer, and better suited to frequent travel and accidental drops than even the about thoroughly ruggedized hard drives.
Why (and Why Not) SSDs?
Different a difficult bulldoze, which stores data on spinning platters accessed past a moving magnetic head, a solid-state drive uses a collection of "persistent" flash retentiveness cells to relieve data. These are similar to the silicon that makes upward a calculator's RAM, but they retain your information when electrical power is cut off.

Since hard drives are mechanical devices that use mature engineering science, yous can get relatively huge amounts of storage chapters for the money. But the aforementioned tech that makes difficult drives a tantalizing value becomes their biggest liability when used on the go. If you drib the bulldoze, you could damage the interior machinery and make your data inaccessible. By contrast, if y'all jolt an SSD while you're reading or writing information, in that location is no risk that your files volition become corrupted and unreadable.
And, over again, hard drives are slower because they have to physically access your data. Only how much faster is it to read data from flash cells than from particular points on spinning platters? Typical throughput for consumer hard drives is in the range of 100MBps to 200MBps. (One factor is spin rate—amidst external drives, 5,400rpm units are more common and more affordable than seven,200rpm.)
Our typical benchmark-test results for even run-of-the-mill external SSDs show speeds in excess of 400MBps. Practically speaking, this ways you can move gigabytes of information (say, a 4GB feature film, or a twelvemonth'due south worth of family unit photos) to your external SSD in seconds rather than the minutes information technology would have with an external hard bulldoze.

Still, you lot do pay for that speed and immovability. Want a 2TB portable hard drive? You lot tin can discover one from major brands such as Seagate and Western Digital for as little as $60. A 2TB external SSD, on the other hand, will run you virtually $250 to $300. That'south not a typo—y'all'll pay four or five times as much for the same amount of storage. If speed, resilience, and portability are critical to you, all that extra money is probably worth information technology. If they're not, continue with intendance. When considering whether to buy an external SSD, make certain y'all know what you're paying a premium for.
External SSDs are now readily available and cheaper than they were a few years ago, but they'll probably never be a consummate replacement for hard drives. Physically larger external drives designed to stay on your desk or in a server closet yet more often than not use 3.five-inch platter drives inside, taking advantage of their higher capacities and much lower prices per gigabyte compared with SSDs.
Inside and Out: Understanding External SSD Interfaces
External solid-state drives are, essentially, internal SSDs (the same kind that power laptops or live inside desktops) with an outer shell and some bridging electronics. Equally a upshot, external drives use one of two internal "bus types" that, in office, dictate their peak speed: Serial ATA (SATA), or PCI Express (PCIe). The latter is commonly associated these days with Non-Volatile Retentiveness Express (NVMe), a protocol that is optimized for the characteristics of SSDs and speeds up data transfers.
SATA-based drives tend to be a little cheaper; they're also slower, only just fine for most users' everyday applications. SATA-based SSDs typically top out at effectually 500MBps for tiptop read and write speeds, just a flake below the ceiling of the USB 3.0 interface. (Much more well-nigh that in a moment.) However, if you're going to be transferring big files such as videos often, you may well want to jump for a PCIe/NVMe-based external SSD. That likewise ties in with the port you'll plug your SSD into.
Sellers of portable SSDs seldom indicate if the drive is SATA- or PCIe-based. However, checking the specs tin be a dead giveaway. If the drive tops out at sequential read and write speeds between 400MBps and 550MBps, it'southward very likely SATA-based. Speeds of 800MBps or higher indicate a PCIe-based drive.
SSD and USB: And then Many Subtleties!
Arguably more than important than the blazon of storage mechanism inside an external SSD is how it connects to your PC or Mac. Almost all external SSDs today plug into either some flavor of USB port or a Thunderbolt 3 or 4 port.
Alas, there are enough different flavors of USB to brand your caput spin—fabricated worse by the confusing classification surrounding USB these days. For case, today's USB 3.2 standard is for all intents and purposes identical to USB 3.1, just renamed. (Information technology gets improve: The forthcoming USB4 will blot Thunderbolt iii.) That said, you'll still see older USB terminology on your PC or Mac and on many SSDs, so you demand to know what term correlates to what.
To begin with, you can forget almost USB 2.0, whose theoretical bandwidth of 60 megabytes per second (60MBps) is a bottleneck even for a platter drive. (These ports notwithstanding exist on desktops and laptops, just you lot won't want to apply one with any portable drive if you can assistance it, and all USB-interface external SSDs will support some flavor of USB 3.) The most usually used port at your computer'southward end for external drives of all stripes is USB 3.0, which offers a theoretical peak bandwidth of 640MBps. Until recently, near SSDs' existent-world transfer speeds topped out somewhere in the range of 450MBps or below, and so these ports were fine.
(Photograph: Zlata Ivleva)
In addition to 640MBps, yous'll also see USB 3.0'due south theoretical data rate described every bit 5Gbps. (That'due south gigabits, not gigabytes, per second.) You also may encounter this interface dubbed "USB three.1 Gen 1" or "SuperSpeed USB 5Gbps" (in practice, all 3 are the aforementioned matter), to differentiate it from "USB three.1 Gen two" or "SuperSpeed USB 10Gbps," which raises the ceiling to (you lot guessed it!) 10Gbps. USB 3.1 Gen ii is the latest version widely available in consumer external SSDs at this writing. PCIe external SSDs can take advantage of the extra 5Gbps of bandwidth, but you demand to have a USB port that supports the spec to see the actress speed benefit. (And yes, we are talking about "USB 3.1" every bit opposed to "USB 3.two." Bear with us.)
In 2019, the USB Implementers' Forum appear that the USB 3.i flavors were being rebranded as "USB three.2." With that alter, you'll want to know these four modes: 5Gbps ("USB three.2 Gen 1"), 10Gbps ("USB 3.ii Gen 2x1," and Gen 1x2, the former achieving the 10Gbps speed on one "lane," the latter via 2 5Gbps lanes), and 20Gbps ("USB 3.2 Gen 2x2," aka "SuperSpeed USB 20Gbps"). All of these versions of USB are backward-compatible with the USB 3.0 ports on your PC; operation will merely bounce downward to the slower of the ii (the bulldoze's supported spec, or that of the organisation-side port).
You won't see many USB iii.2 Gen 2x2-capable ports on PCs so far (some late-model loftier-end desktop motherboards have one), only look to that new USB spec to matter more as the 2020s motion on.
Really, all this calls for a little nautical chart to keep information technology direct...
Equally you can come across, some USB specs are tied to certain arrangement-side physical USB connectors; we'll become into that in a moment.
...and And so At that place's Thunderbolt 3
Thunderbolt 3 offers a blazing meridian bandwidth of 40Gbps. Compatible ports are institute on all late-model Macs and, increasingly, some upscale Windows laptops. Those ports are actually USB Type-C connectors with the Thunderbolt support layered on top. However, Thunderbolt 3 SSDs are not backward-compatible with USB Type-C ports that only support USB transfers. The port has to specifically support Thunderbolt 3; wait for the little lightning bolt on port and cable connector...

Thunderbolt 3 is the least-common external SSD interface, and SSDs that use it are frequently geared toward Mac users, since all late-model Mac laptops take Thunderbolt iii ports. You lot'll notice Thunderbolt iii on resolutely speed-focused drives, such equally the Samsung Portable SSD X5 and on some specialized desktop-style drives that may incorporate multiple SSDs in a RAID format.
Almost workaday SSDs don't come close to saturating this interface, so there'southward no point in paying a premium for a Thunderbolt 3 drive unless y'all specifically need the speed. You tin can employ a Type-C USB drive on a Thunderbolt 3 port, and then you're non bound to buying a Thunderbolt 3 drive on a PC with only those ports, such as a Mac.
The Last Interface Wrinkle: The Physical USB Port
Got interface fatigue nonetheless? Alas, that'due south not the last thing to consider around USB and Thunderbolt 3!
System-side concrete USB ports these days accept the form of USB Blazon-A (the familiar, older rectangular kind) and USB Blazon-C (smaller and roughly oval). This physical type is not necessarily an indicator of which specific USB transfer-charge per unit spec the port supports. Simply y'all need to make sure you can plug in what you go.

Many SSDs come with cables for both kinds (Type-A and Blazon-C) at the computer finish, or i cablevision plus an adapter. Two full cables is by and large best, equally adapters tin be clunky or easy to lose. You'll want to match what comes in the box with which specific ports your PC has (and has free). You'll besides desire to match specs; in that location may not be much bespeak in spending extra, for case, for a 10Gbps USB 3.2 Gen 2 SSD if you lot only accept 5Gbps-capable ports.
Also: Don't misfile the system-side interface with the connector that joins the cable to the drive itself. On most newer portable SSDs, the connector at the SSD end is a USB Type-C port (the aforementioned every bit the kind you might notice system-side)...
(Photo: Zlata Ivleva)
On others, though, the connector might be a Micro-USB Type-B, which is a apartment, wide connector that is dissimilar from whatever USB port yous'll see on a laptop or desktop.
Do Y'all Need to Get Rugged?
Indeed, if you comport your drive effectually oftentimes, yous'll want to pay attending to how rugged the bulldoze is. Some models include plastic bumpers, and some even encounter armed services standards for shock and dust protection. Look for support for Ingress Protection ratings such equally IP68, explained at the previous link.

And of course, if you lot're carrying your drive around with you, you desire information technology to look nice. Some come up in multiple colors, while most are minor and slim enough to be tucked into a shirt pocket.
Recommended by Our Editors
Perhaps the only thing you don't need to weigh as well heavily is the warranty. If your drive breaks because you damaged it, the warranty likely won't cover information technology. Fifty-fifty if the drive fails because of a manufacturing defect, nigh warranties simply replace the drive and don't cover the cost of recovery services that attempt to rescue your information from the device. A long warranty is well and skillful, just the existent value in a bulldoze normally lies in what yous have on it.
This is likewise where a spec known equally the "terabytes written" rating (or TBW) comes in. It refers to how much data can exist written to a drive earlier the individual cells on that drive begin to neglect. This procedure doesn't mean that the entire drive itself will terminate functioning, but rather that less and less storage will exist made available as time goes on.
External SSD Buying Nuts
Here are iii key things to look out for when shopping for an external SSD:
Price PER GIGABYTE. The way to calculate relative value on drives like these is to perform some simple math and figure the cost per gigabyte based on the cost of a given bulldoze on the day you're shopping. Considering SSD pricing fluctuates all the time, relative value does, too.
Generally, the higher a bulldoze's capacity, the cheaper it will exist per gigabyte. But that's not always true; sometimes the very highest-capacity drives come at a per-gigabyte price premium. The basement for budget external SSDs at this writing was near 12 to 15 cents per gigabyte, mostly from 2d- or third-tier vendors. Calculate your bottom-line price when comparing a host of drives.
RUGGEDIZATION. The degree of ruggedness does vary from bulldoze to drive, with drives like the ADATA SE800 leading the field at the moment amongst mainstream-cost external SSDs. IP68 certification is a good spec to look for if you're serious about waterproof and dustproof drives.

Some models, though, like a few from Apricorn'south Fortress serial, combine major ruggedness with physical and electrical security; information technology's almost impossible to crack open those drives to get at the PCBs inside without destroying them.
Carry WEIGHT. Most SSDs weigh a negligible couple of ounces. The carabiner retentivity loop of SanDisk'south Extreme family of external SSDs is specially handy, considering many SSDs are small and light plenty that losing them is an like shooting fish in a barrel and expensive mistake.
Should You Make Your Own Portable SSD?
If none of the drives we've selected for this roundup sounds highly-seasoned to you (or yous already own an internal SSD that'southward hanging around the house or function), there's 1 more than option available: SSD enclosures. These are plastic or metal housings into which you can put your own SATA ii.5-inch or M.two solid-state drive to take with you on the go.
Enclosures come in 2.v-inch class factors (into which yous would put a ii.5-inch SATA SSD) or Chiliad.2 ones. The stick-fashion M.2 SSD is much smaller and lighter, but know that M.two drives themselves come in both SATA and PCIe bus flavors. You lot need to exist sure your enclosure supports the kind of 1000.two bulldoze yous're putting in it.
Also, merely considering you put a PCIe NVMe drive in an enclosure doesn't mean you should magically look it to get any faster than a standard external SSD. Any drive placed in an enclosure is all the same subject to the elevation USB speed supported by the enclosure electronics and past the USB protocol supported by the port you lot plug it into.
Though there are exceptions, most enclosures are not as durable or rugged equally major-maker portable SSDs are. This can be a drawback for those who take their SSDs into unsafe environments (recall wildlife photographers or first responders), so exist sure that before you lot go this route, you know what your drive will exist exposed to. Your information could exist at greater gamble for corruption than it would be in an SSD purpose-congenital to withstand the elements.
So, Which External SSD Should I Purchase?
Our all-time SSD picks vary widely in features and cost, but all should all deliver enough of speed and peace of mind if that's what you desire from your portable storage. Don't need (or don't want to spring for) an SSD? Then check out our roundup of the best external hard drives.
