Whether or not you need to again up the info in your PC, switch movies out of your Mac or offload a number of video games out of your PlayStation 5, a transportable SSD is a straightforward method to develop your storage. These little bricks could value greater than conventional exterior laborious drives, however they’re considerably quicker, lighter and extra dependable. However determining the most effective transportable SSD for you isn’t so simple as simply choosing the one with the bottom worth or essentially the most house. (Nicely, it can be, however that wouldn’t be very environment friendly.) To assist, we’ve spent the previous couple of months weeding by the transportable SSD market, testing a bunch of contenders and finding out which of them present essentially the most worth. You’ll find our prime picks, plus an summary of what to know earlier than shopping for, under.
What to contemplate earlier than shopping for a transportable SSD
Capability
The very first thing to determine earlier than shopping for a transportable SSD is simply how a lot space for storing you want. A lot of the drives we thought-about for this information can be found in capacities starting from 1TB to 4TB, although loads of smaller and bigger choices exist.
There’s no hard-and-fast rule for which dimension is “best” — that’ll finally rely in your finances and what precisely you’re trying to stash. However normally, it’s higher to overcompensate than underdo it. No one needs to be compelled into shopping for a second drive as a result of they stuffed the primary one up too rapidly. In case you’re backing up a PC, rule of thumb is to purchase a transportable SSD with twice as a lot house as your laptop’s inner storage. This manner, it can save you at the very least one full backup whereas additionally having room for extra knowledge. If you wish to retailer a bunch of PlayStation or Xbox video games with enormous set up sizes, it’s possible you’ll want extra space. In case you simply need to again up a small assortment of information, it’s possible you’ll be higher off saving your money and simply getting a smaller USB flash drive as an alternative, which aren’t fairly the identical because the transportable SSDs we examined for this information.
Value
Generally, you get a greater price-per-gigabyte ratio the additional you go up the capability ladder. As of this writing, the 1TB Samsung T9 is priced at $135, or $0.14 per gigabyte (GB), whereas the 4TB model is out there for $360, or $0.09 per GB. That technically makes the bigger mannequin a greater “value,” however not everybody must pay that rather more upfront.
SSDs in the identical pace class are likely to not fluctuate too wildly by way of efficiency, so a part of our decision-making for this information got here right down to which of them are sometimes the most cost effective. However costs can fluctuate over time; for those who see that one among our prime picks is priced method larger than a comparable honorable point out, be happy to get the latter. At this time limit, prices are broadly trending upwards.
Velocity and USB interface
Nearly all transportable SSDs are considerably quicker than mechanical laborious drives, so that you’ll save time ready for information to switch and video games to load it doesn’t matter what. Throughout the market, nevertheless, there are distinct efficiency tiers. These are outlined largely by the USB interface a drive helps. Whereas all the SSDs we thought-about for this information can join over USB-C, some USB-C connections can provide quicker switch speeds than others. Sorting by this will get actual complicated actual quick, so we’ll attempt to put it in easy phrases.
Primarily, you possibly can divide at the moment’s crop of transportable SSDs into 5 segments. On the prime are drives that make the most of Thunderbolt 3 or 4 or the more moderen USB4 spec, which have a theoretical most switch charge of 40 gigabits per second (Gbps). Word that USB4 is available in two totally different variants, although, one among which is proscribed to twenty Gbps. Under that’s USB 3.2 Gen 2×2, which additionally tops out at 20 Gbps. (Getting confused but?) Then you’ve got USB 3.2 Gen 2, which maxes at 10 Gbps. Subsequent is USB 3.2 Gen 1, which is capped at 5 Gbps. Lastly, we’ll bundle collectively SSDs that use older requirements and aren’t value contemplating right here.
For on a regular basis people, USB 3.2 Gen 2 drive is the candy spot between quick sufficient efficiency and an inexpensive sufficient worth, so these make up our chief suggestions under. In case you work in a artistic subject or don’t thoughts paying additional to shave seconds off your massive file transfers, although, a “higher-tier” mannequin would make sense. Nevertheless, notice that methods that make the most of USB 3.2 Gen 2×2 aren’t tremendous frequent — no Mac helps it, for one — and the interface is successfully being changed by USB4.
Generally, your chain is simply as robust as its weakest hyperlink: In case your laptop solely has USB 3.2 Gen 2 ports, for instance, you possibly can nonetheless use a Thunderbolt SSD, however you received’t get past Gen 2 speeds. Be sure to know what you’re working with before you purchase.
As a refresher, storage gadgets are broadly measured by way of learn and write speeds. The previous refers to how lengthy it takes to entry one thing from the drive; the latter, how lengthy it takes to save lots of one thing to it. From there, you possibly can break these metrics into sequential and random efficiency. Sequential speeds are likely to matter extra with transportable SSDs, since most individuals use them to save lots of or entry lengthy, fixed streams of information comparable to a bunch of high-res pictures. Random speeds could be vital if you wish to run video video games off the drive, since that’d contain studying and writing smaller, extra scattered information. Both method, how properly an SSD can maintain its efficiency with prolonged use can be essential.
Different efficiency components and enclosures
A contemporary transportable SSD’s speeds aren’t nearly its USB interface, although. Its efficiency may depend upon how superior its controller is, whether or not it has a local USB flash controller or a separate bridge chip to speak with a bunch machine, the type and high quality of NAND flash reminiscence it makes use of, whether or not it has a DRAM cache or it’s DRAM-less, and extra.
We’re simplifying issues, however listed here are some fast ideas: Drives with triple-level cell (TLC) reminiscence aren’t as low-cost as quad-level cell (QLC) SSDs, however they’re typically extra dependable they usually supply higher write efficiency. Having a devoted DRAM cache helps for those who plan to hit your drive with extra intense, sustained workloads, however is probably not value the additional value for most individuals. Some fashions with native flash controllers could not carry out in addition to these with a bridging chip, relying on the SSD inside, however they usually draw much less warmth and are bodily smaller. All of that is to say {that a} transportable SSD’s speeds aren’t fairly as easy as what the producer chooses to promote on the field.
It’s additionally value remembering that you could flip an “internal” SSD into a transportable answer with enclosure. You probably have a spare drive and don’t thoughts going the DIY route, this is usually a cheaper and extra versatile answer, although we’ve caught to pre-built fashions for this information for the sake of simplicity.
Measurement, sturdiness, endurance and guarantee
Most transportable SSDs are impressively small and light-weight, in order that they received’t be tough to tuck in a bag (or perhaps a pocket) and tackle the go. We notice under if any drive is bulkier than standard.
Nothing we’re speaking about issues in case your drive can’t final in the long run. It’s laborious to definitively say which transportable SSDs are essentially the most dependable, however we scoured by person critiques and suggestions whereas researching this information to make sure none of our picks present a sample of catastrophic errors. If there was an excessive amount of smoke round a selected mannequin, we steered clear. We dominated out sure drives from SanDisk and WD, as an example, after stories from Ars Technica and The Verge famous a problem that led to knowledge loss (and lawsuits) in 2023.
That mentioned, one of many huge causes you’d purchase an SSD normally is its superior sturdiness. As a result of it has no transferring mechanical elements inside, a transportable SSD has far fewer avenues to failure than an exterior laborious drive. You continue to don’t need to be careless with them, however an unintentional drop shouldn’t be the top of the world.
Some transportable SSDs construct on this inherent ruggedness with plastic or rubberized casings and extra sturdy waterproofing. These aren’t obligatory for everybody, however for those who’re a frequent traveler or somebody who typically works outdoor, there are alternatives for you.
Nonetheless, all drives can fail. You probably have any form of knowledge you’d be distraught to lose, you need to again it up commonly, then make a second backup, ideally with a cloud service. Alongside these protecting strains, we additionally took notice of the guarantee coverage for every drive we examined. Nearly all of them are backed for both three or 5 years; in fact, longer is best.
Encryption and software program
It’s not unusual to retailer delicate knowledge on a transportable SSD, so some fashions supply additional safety features like hardware-based encryption — i.e., direct scrambling of information saved on the drive itself — built-in keypads and fingerprint readers to guard in opposition to unauthorized entry if the drive is misplaced or stolen. Whereas not prime necessities, perks like these are definitely good to have. Some SSDs additionally include companion software program to additional handle the drive. The most effective of these will be helpful to have round, however we wouldn’t name them important.
How we take a look at transportable SSDs
Sadly, we didn’t have entry to a tool that may make full use of USB 3.2 Gen 2, USB 3.2 Gen 2×2 and Thunderbolt 4/USB4 speeds interchangeably, so we needed to break up our testing throughout a number of gadgets, together with an M1 Professional MacBook Professional and an Alienware gaming PC working Home windows 11. Due to this, we primarily in contrast the transportable SSDs inside every “class” in opposition to each other. Earlier than switching OSes, we reformatted every drive to every platform’s normal file system format: APFS for macOS and NTFS for Home windows.
After researching which SSDs had sufficient optimistic suggestions to be value testing within the first place, we put 13 drives by a spread of artificial and “real-world” benchmark checks. On Home windows, these included CrystalDiskMark, PCMark 10’s Information Drive Benchmark and 3DMark’s gaming-focused Storage Benchmark. On macOS, we used AmorphousDiskMark (successfully a Mac model of CrystalDiskMark), BlackMagic Disk Velocity Check and ATTO Disk Benchmark.
We additionally timed how lengthy it took for every drive to learn and write a customized 70GB folder crammed with roughly 11,500 totally different information, together with pictures, movies, music information, PDFs and different massive and small knowledge sorts scattered throughout quite a few subfolders. We carried out a number of passes for every take a look at to keep away from irregularities, and we stored monitor of every SSD’s warmth ranges over the course of the entire suite. Our course of wasn’t an ideal science, but it surely gave us a normal sense of how every drive compares to different fashions in its worth and efficiency vary.

Capacities: 1TB, 2TB, 4TB | Measurement: 2.56 x 1.97 x 0.39 inches | Weight: 1.34 ounces | USB interface: USB 3.2 Gen 2 | Controller/bridge chip: Silicon Movement SM2320 | NAND kind: TLC | Rated most sequential speeds: 1,050 MB/s learn, 1,050 MB/s write | Guarantee: 5 years
The Essential X9 Professional completed at or simply below the highest in every of our benchmarks relative to its pace class, and it stayed noticeably cooler than a lot of the different drives we examined after prolonged use. It’s a USB 3.2 Gen 2 mannequin, so it’s slower than options primarily based on Thunderbolt, USB4 or USB 3.2 Gen 2×2, but it surely prices much less, and it’s nonetheless fast sufficient for the non-professional duties most individuals do with a transportable SSD. Ports that may really make the most of USB 3.2 Gen 2 speeds are typically extra ubiquitous on mainstream computer systems, too. This isn’t the most cost effective 10 Gbps drive round, but it surely’s in the identical ballpark as its friends and isn’t too costly. As of this writing, a 1TB mannequin is out there for $95, although we’ve seen it fall as little as $60 previously. 2TB and 4TB variations are additionally accessible.
In addition to its comparatively speedy efficiency, the X9 Professional stands out for being so tiny. Its aluminum case is shorter than a bank card and straightforward to slot in a pocket, weighing in at simply 1.34 ounces. The entire thing is IP55-rated, so it’ll survive mud and water splashes, and it’s backed with a five-year guarantee, which is a pair years longer than some options.
Our solely actual complaints are that the included USB-C cable is small and there’s no adapter for USB-A ports within the field. And although the X9 Professional can make the most of 256-bit hardware-based encryption, Micron (Essential’s mum or dad firm) has but to launch a promised password safety device to make the most of it. We’ll additionally notice that there’s a less expensive non-”Professional” X9, however that one makes use of QLC flash, so it’s not as sturdy or quick (particularly with sustained writes). The X9 Professional is the higher purchase.
- Nice efficiency for its pace class
- Rugged and tremendous compact design
- Stays comparatively cool with prolonged use
- 5-year guarantee
- There are cheaper 10 Gbps drives
- Included USB-C cable is brief, and there is no USB-A cable within the field

Capacities: 1TB, 2TB | Measurement: 2.74 x 1.28 x 0.53 inches | Weight: 1.01 ounces | USB interface: USB 3.2 Gen 2 | Controller/bridge chip: Silicon Movement SM2320 | NAND kind: TLC | Rated most sequential speeds: 1,050 MB/s learn, 1,000 MB/s write | Guarantee: 5 years
The Kingston XS1000 performs equally to the Essential X9 Professional however has offered for much less over the past a number of months, so it’s different if you wish to avoid wasting money. A 1TB mannequin is out there for $75 as of this writing, which is $20 lower than the X9 Professional, whereas the 2TB model is right down to $120, which is a roughly $40 drop. There’s no 4TB possibility, although.
At these costs, the XS1000 is an effective worth for on a regular basis backups and transfers. It stored up with or barely edged the X9 Professional throughout our benchmarks: In our customized file switch take a look at, for instance, its reads had been a second quicker, whereas its writes had been solely six seconds slower. (The 2 drives seem to have comparable internals and are primarily based on an analogous controller — the Silicon Energy SM2320G — so this is probably not an enormous shock.) It topped each USB 3.2 Gen 2 drive we examined in 3DMark’s gaming storage benchmark as properly. It’s barely thicker than the X9 Professional however nonetheless splendidly transportable, with its stubby rectangular design weighing simply over an oz. Just like the Essential drive, it’s backed by a five-year guarantee.
The place Kingston’s mannequin falls behind Essential’s X9 Professional is within the extras. There’s no formal IP or drop rankings, so we wouldn’t really feel as comfy chucking it round on the go. It lacks hardware-based encryption, and it solely comes with a USB-C to A cable, so that you’ll want to produce your personal adapter in case your laptop computer solely has USB-C ports. It doesn’t keep fairly as cool because the X9 Professional with steady use, and its sustained write efficiency isn’t as quick both, so it’s value paying up for those who plan to commonly copy lots of of gigabytes to the SSD (and might’t simply get a higher-class mannequin). For the cash, although, all of this can be simpler to miss.
- Sooner than most 10 Gbps drives we examined
- Aggressively priced
- Extremely transportable
- 5-year guarantee
- No formal water-resistance or drop safety
- No USB-C to C cable within the field
- Solely accessible in 1TB or 2TB
- Slower sustained write efficiency than X9 Professional with very massive information

Capacities: 1TB, 2TB, 4TB | Measurement: 4.13 x 2.52 x 0.62 inches (with fan off), 4.82 x 2.52 x 0.62 inches (with fan on) | Weight: 6.4 ounces | USB interface: USB4 (40 Gbps) | Controller/bridge chip: Asmedia ASM2464PD | NAND kind: TLC | Rated most sequential speeds: 3,800 MB/s learn, 3,700 MB/s write | Guarantee: 5 years
In case you’re a media editor, IT skilled or simply an fanatic prepared to pay for the quickest transportable SSD doable, get the ADATA SE920. It makes use of the newer USB4 interface, and it blew away each non-40 Gbps drive we examined throughout our benchmark checks. In AmorphousDiskMark, for instance, the Essential X9 Professional delivered sequential reads and writes round 1,015 MB/s and 950 MB/s, respectively; right here, these had been about 3,350 MB/s and three,125 MB/s. In our customized blended file switch take a look at, we had been capable of transfer our 70GB folder to our MacBook in 32 seconds; with the X9 Professional, that course of took about 81 seconds on common. Writing the folder to the drive, in the meantime, was about 30 seconds quicker. In case you’re shopping for a transportable SSD to maneuver round massive chunks of information, this sort of leap provides up.
The drive itself is considerably greater and thicker than both of our picks above, but it surely’s not so massive that we’d name it unwieldy. It’s in regards to the dimension of a deck of playing cards, so it’ll match higher in a bag than a pants pocket. Past that, the brushed metallic exterior feels crisp to the contact, and ADATA helps the machine with a five-year guarantee.
That mentioned, this factor can get significantly sizzling. The design features a built-in micro fan to assist dissipate warmth, which you activate simply by clicking the case down; that’s intelligent, but it surely’s not sufficient to maintain the drive cool by itself. All of this comes at a worth premium, too, with a 1TB mannequin presently accessible for $180. But when efficiency is the one factor that issues to you, it’s laborious to do higher.
- Blazingly quick 40 Gbps efficiency
- Slick metallic enclosure
- Smaller than different Thunderbolt SSDs we examined
- Intelligent built-in fan
- 5-year guarantee
- Will get sizzling even with fan activated
- Pricier and nonetheless bigger than different picks
- Requires USB4 port to succeed in most speeds

Different transportable SSDs we examined
The pre-built OWC Specific 1M2 is a premium-feeling USB4 SSD that’s roughly as quick because the ADATA SE920, but it surely’s bigger and considerably dearer as of this writing.
In case you’re within the comparatively small group with a PC that helps USB 3.2 Gen 2×2 however not Thunderbolt or USB4, the Essential X10 Professional is actually a quicker model of our prime choose. The Lexar SL600 is a bigger however barely faster possibility, whereas the Lexar SL500, Kingston XS2000 or Samsung T9 may additionally work for those who see them on low cost. As a reminder, although, drives like these are aimed primarily at content material creators and different professionals, and you need to be sure you received’t improve to a tool with a quicker USB interface anytime quickly.
The Samsung T7 Protect has a conveniently rugged design with a rubberized, IP65-rated shell. It additionally comes with each USB-C and USB-A cables. However it was persistently slower than the X9 Professional and XS1000 in our benchmark checks, plus it has a shorter three-year guarantee.
The Silicon Energy PX10 is an particularly inexpensive USB 3.2 Gen 2 mannequin. Its peak speeds weren’t too far off the X9 Professional or XS1000 in artificial benchmarks, however it could actually get distractingly sizzling and its sustained writes are markedly worse. It took 50 seconds longer to maneuver our 70GB customized take a look at folder to this drive in comparison with the X9 Professional, for instance.
The Essential X6 is one other low-cost possibility that’s bit slower than our prime picks. It’s restricted to a three-year guarantee and lacks an IP score as properly. It’s not a horrible possibility for the fundamentals, however there’s little cause to get it over the XS1000 when their costs are related.
The OWC Envoy Professional FX is well-built and helps Thunderbolt 3 and USB 3.2 Gen 2, but it surely’s a smidge slower than the SE920 and Specific 1M2, and it’s a lot pricier than the previous.
