Before you purchase

Because of the present international scarcity of NAND (Thanks AI!), SSD costs have skyrocketed. Most of the costs quoted under and within the referred critiques will quickly be, or are already old-fashioned.

As of February 21, 2026 we’ve skilled at the very least two drives that carried out properly under expectations when used with their bundled cables. In case your new exterior SSD doesn’t carry out as much as snuff, speak to the seller a few firmware replace, or use a Thunderbolt cable of appropriate pace, which is how we solved the difficulty for testing. Thunderbolt cables are usually of far larger high quality than some commodity USB cables.

Drive exams at present make the most of Home windows 11 24H2, 64-bit operating off of a PCIe 4.0 Samsung 990 Professional in an Asus Z890-Creator WiFi (PCIe 4.0/5.0) motherboard. The CPU is a Core Extremely i5 225 feeding/fed by two Kingston Fury 32GB DDR5 4,800MHz modules (64GB of reminiscence whole). Each 20Gbps USB and Thunderbolt 5 are built-in and Intel CPU/GPU graphics are used. SSDs concerned within the check are mounted in both a HighPoint 7604A 16x 4-slot PCIe 5.0 RAID adapter card or a single-slot Asus ROG M.2 PCIe 5.0 adapter.

We run the CrystalDiskMark 8, AS SSD 2, and ATTO 4 artificial benchmarks to seek out the storage machine’s potential efficiency, then a collection of 48GB and 450GB transfers exams utilizing Home windows Explorer drag-and-drop to point out what you’ll see below Window, in addition to the far quicker FastCopy to point out what’s doable. A two-drive 25GBps RAID 0 array on the HighPoint 7604A 16x PCIe 5.0 adapter card is used because the secondary supply/vacation spot.

Every check is carried out on an NTFS-formatted and newly TRIM’d drive so the outcomes are optimum. Word that in regular use, as a drive fills up, efficiency could lower on account of much less NAND for secondary caching, in addition to different components. This may be much less of an element with the present crop of SSDs with far quicker late-generation NAND.

Caveat: The efficiency numbers proven apply solely to the drive we had been shipped and to the capability examined. SSD efficiency can and can fluctuate by capability on account of extra or fewer chips to shotgun reads/writes throughout and the quantity of NAND accessible for secondary caching. Distributors additionally often swap elements. For those who ever discover a big discrepancy between the efficiency you expertise and that which we report, by all means, tell us.

Jon L Jacobi has witnessed storage morph from punch playing cards and tape to strong state. He’s been utilizing and testing HDDs, SATA SSDs, and NVMe SSDs for PCWorld for properly over twenty years. To paraphrase a well known business, you may say he’s seen a factor or two.

There are 4 normal classes with regards to exterior storage, all pretty self-explanatory: transportable SSD, transportable HDD, desktop HDD (sometimes bigger capability, bigger footprint, and requiring exterior energy, and thus meant to be stationary), and thumb-drive SSD — the smallest and most transportable exterior storage, however usually restricted in capability.

SSD vs. HDD

For those who’re trying to deal with your exterior storage as an extension of your inner storage, then efficiency is probably going paramount. You’ll need an SSD, which may be 10 to twenty occasions quicker — relying on the interface — than a tough drive. SSDs additionally provide sub-millisecond search occasions the place HDDs search at tens of milliseconds.

However, if the first position is backup, you then may wish to go for a tough drive (HDD) with its bigger capability and a considerably cheaper price per gigabyte/terabyte. Presently, single SSDs high out at 8TB, 2.5-inch HDDs at 6TB, and desktop 3.5-inch HDDs at 36TB.

Want inner storage as a substitute? See our guides to the most effective SSDs and greatest PCIe 4.0 SSDs.

SSD/HDD capability versus worth

The associated fee per TB of each SSDs and HDDs tends to drop as capability will increase. Nonetheless, the most recent, best (highest capability) drives of each varieties have a tendency to hold a premium, just because the corporate is aware of some customers need as a lot capability as they'll get and are prepared to pay extra.

Usually, you’ll get the bottom worth per terabyte from the second-highest capability drive, aka final years mannequin. However do the maths earlier than you plunk down your hard-earned cash — you could discover offers. Beneath you may see the phenomenon by way of a WD 2.5-inch HDD.

IDG

Above you may see the final extra capability, cheaper per terabyte pattern.

How a lot exterior storage capability do you want?

For those who’re extending your inner storage, you most likely know higher than we do how a lot you’ll want. Video sucks up house at a exceptional tempo, particularly at larger resolutions. With SSDs, historically we’ve advisable twice the capability you assume you’ll want as older varieties tended to decelerate as they stuffed. Trendy SSD controller design has mitigated this to an amazing diploma, however it’s nonetheless our rule of thumb.

For those who’re going for backup, then the extra the merrier. Once more, twice the quantity of whole knowledge on the drives to again up is an efficient begin. Keep in mind, you’ll need at the very least one full system backup, then common incremental, differential, or data-only backups.

That stated, reinstalling Home windows and your functions isn’t fairly the insane drudgery it as soon as was, and you'll probably get away with simply backing up your knowledge. In that case twice the quantity of important knowledge you've got will do the trick. Sensing a 2X pattern right here?

One other rule of thumb: 1TB for journey and lightweight backups, 2TB for mainstream picture/video libraries, 4TB+ for bigger archives, 8TB+ for desk-bound bulk backup.

Word that these are our minimal suggestions. The extra the merrier, and the additional again in time you may maintain backups for.

Which exterior interface must you go for?

Pace

For those who’re shopping for an HDD, the interface is comparatively unimportant — even older 5Gbps USB provides greater than sufficient bandwidth to accommodate the 300MBps that's as quick as a contemporary HDD can ship knowledge. In actual fact, you’re unlikely to run throughout an exterior HDD that gives a quicker interface until it’s a multi-bay RAID field. Even then, 10Gbps is prone to be greater than quick sufficient.

For SSDs, there’s an enormous distinction in efficiency relying on the interface concerned. The internals of most exterior SSDs lately are NVMe slightly than SATA, and able to 3GBps. It doesn't matter what the internals, 5Gbps USB (3.0) limits the drive to simply over 500MBps, 10Gbps USB (3.2) to simply over 1GBps, and 20Gbps USB (3.2×2)/Thunderbolt 2 to round 2GBps, so that you’re leaving efficiency on the desk with any of these.

In fact, these could also be all that your laptop provides, so purchase to match. Nonetheless, in the event you’re rocking a more moderen laptop you'll have Thunderbolt 3/4/5 or if it’s actually latest, USB4. These will ship round 3.5GBps until they’re the nonetheless uncommon 80Gbps flavors during which case you’ll see round 6.5GBps.

Word that each one these numbers are what you’ll see with artificial benchmarks. Home windows Explorer is a horrible performer in knowledge transfers. We suggest utilizing FastCopy or in the event you’re a command line kind — Xcopy. Each of that are two to a few occasions as quick as Explorer transferring massive recordsdata.

Compatibility

Compatibility is a significant concern and the place 5Gbps and 10Gbps USB reign supreme. You’d be exhausting pressed to seek out a pc or machine that gained’t help them and so they operate on practically each USB and Thunderbolt port in existence.

USB 3.2×2 alternatively requires a devoted 20Gbps port or a more moderen USB4 port to operate on the full 20Gbps pace. They drop to 10Gbps on 10Gbps USB ports and most Thunderbolt ports.

Clearly, 40Gbps USB4 requires a USB4 port or Thunderbolt 4/5 port to achieve most pace. However on USB4 ports, even that’s not assured. We haven’t seen one but, however full 40Gbps implementation in true USB Discussion board vogue, isn’t required, so there is likely to be slower 20Gbps USB4 SSDs and ports.

Thunderbolt SSDs usually require a Thunderbolt 3/4/5 port or USB4 port to operate at 40Gbps. In reality, USB4 is principally Thunderbolt 4 with some minor tweaks. 80Gbps Thunderbolt SSDs require a Thunderbolt 5 port, and/or the upcoming 80Gbps USB4 second gen.

USB4 SSDs are simply probably the most suitable (backwards to USB 2.x, ahead to Thunderbolt 5) high-performance varieties, in order that they’re at present our advisable interface for quick knowledge supply. That stated, 80Gbps Thunderbolt 5 is fairly attractive.

What connector kind must you use?

Although the trade is usually on board with Sort-C connectors at this level, you should still discover some older varieties round. From high to backside within the picture under: Mini-USB, Micro B SuperSpeed, SuperSpeed Micro B, Thunderbolt 2/mini DisplayPort, and Sort-C . You’ll additionally discover the occasional Lightning connector drive (not proven). Extra full descriptions observe under.

Whereas we in fact suggest orientation-agnostic Sort-C, yow will discover Sort-C adapters or adapter cables for any kind.

<img decoding="async" data-wp-class--hide="state.isContentHidden" data-wp-class--show="state.isContentVisible" data-wp-init="callbacks.setButtonStyles" data-wp-on-async--click="actions.showLightbox" data-wp-on-async--load="callbacks.setButtonStyles" data-wp-on-async-window--resize="callbacks.setButtonStyles" src="https://legacy-us-images.foundryco.app/images/article/2017/07/usb_portable_drives-100729043-large.jpg" alt="usb portable drives" loading="lazy" /> The highest drive makes use of the older, slower Mini-USB interface. The second drive options the connector that changed it: Micro B SuperSpeed. The Orange drive options each a SuperSpeed Micro B and Thunderbolt 2 (mini DisplayPort connector). The underside drive options USB-C or USB Sort C.

Connectors

USB Sort-C, USB-C, Sort-C is the most recent USB connector and the one the world is standardizing on. It’s small, simple to insert, and also you don’t have to fret about which facet faces up as with Sort-A.

Needless to say Sort-C refers solely to the connector itself. What's carried over the wires varies drastically: USB 2.0 Excessive Pace (480Mbps) to USB 3.2 SuperSpeed 20Gbps, in addition to USB4 and Thunderbolt 3/4/5 and any mixture of them.

USB Sort-A: You gained’t discover this acquainted rectangular port on any drive, however you'll nonetheless discover it on loads of PCs and laptops in addition to the male model on the opposite finish of most Sort-B and Sort-C adapter cables.

USB 3 Micro-B is the broader, flatter port that’s nonetheless quite common on many lower-cost transportable and desktop exterior exhausting drives. It’s really the identical Micro USB port used on older telephones, however with extra knowledge strains to hit USB 3.0 speeds. It’ll do 5Gbps and is ok for exhausting drives and SATA (internally) SSDs. Micro-B cables are usually Sort-A on the PC finish.

USB 3 Sort-B is the bigger, squarer model of USB 3.0 Micro B. Sort B ports have gotten uncommon, although you may discover one on older 5.25-inch enclosures, printers, and scanners. It helps speeds as much as 5Gbps and cables are usually Sort-A on the PC facet.

Thunderbolt 2 is useless at this level. It’s discovered on older Macs, however even Apple put it out to pasture in 2017. There’s no have to put money into a Thunderbolt 2 drive until it’s for legacy help points. That stated…

…Apple sells a bi-directional Thunderbolt 1/2 to three adapter if it is advisable to join the one technology to the opposite. The adapter doesn't, nevertheless, carry energy, so bus-powered exterior drives (no energy jack) would require a powered dock.

eSATA is one other legacy port that’s disappeared from newer units. Created for attaching exterior storage to your laptop’s SATA bus, eSATA was an inexpensive method in its day to maneuver past the toddling 60MBps efficiency of USB 2.0.

5Gbps USB 3.0 put the final nail in eSATA’s coffin. As with Thunderbolt 2, the one purpose to put money into an eSATA drive is to be used with older computer systems.

A number of drives for backup?

We mentioned the rule of three for backup, however whereas the cloud is a superb offsite choice, you may also handle that with a number of exterior drives — storing them in numerous places. As soon as upon a time, I used to recurrently ship copies of my recordings to my mother’s for safe-keeping.

For those who’re utilizing your exterior storage as a major repository for vital knowledge, then it is best to have a second drive as a duplicate. You may even take into account a dual-drive enclosure and run them mirrored, i.e. the identical set of knowledge written concurrently to each. SSDs aren’t practically as vulnerable to mishap as exhausting drives, however even then…

Merely put, maintain your knowledge backed up!

For extra steerage on constructing out the most effective backup plan doable, see our roundups of the most effective cloud backup providers and greatest Home windows backup software program.

Exterior drive FAQ 1. What’s the most effective exterior SSD?

Customers have a variety of glorious exterior SSDs to select from. If pace is vital, the most effective 40Gbps exterior drive is the Adata SE920 at 40Gbps; for 20Gbps efficiency, and a big value financial savings, take into account the PNY RP60; for the most effective steadiness of efficiency and worth, we suggest the 10Gbps Corsair EX300U.

2. What’s the most effective USB thumb drive?

Presently, the Teamgroup X2 Max is the decide of the litter. It’s tremendous slim, however capacious, cheetah quick, and has each Sort-C and Sort-A connectors.

3. What’s the most effective exterior exhausting drive?

For those who’re searching for portability, get WD’s My Passport, Works with USB-C (be aware that it makes use of an adapter for USB-C, not a local USB-C port). For those who’re searching for capability, then it’s Seagate’s Growth Desktop.

4. What's the distinction between an SSD and an HDD?

HDDs (exhausting disk drives) are primarily packing containers containing spinning platters with learn/write arms that skim throughout them to detect the orientation of, or re-align particles within the magnetic materials that coats the platters.

SSDs (strong state drives), alternatively, use flash reminiscence and don't have any transferring components contained in the drive. Knowledge is as a substitute saved in cells — aka, voltage traps — that are interconnected in a matrix. The matrix strategy permits for knowledge to be pushed or pulled to/from many various locations without delay and considerably will increase each learn and write pace — on the order of 100 occasions quicker at present.

Typically talking, SSDs are a greater wager on your exterior drives on account of their smaller dimension, quicker speeds, and much superior sturdiness. The primary downside to SSDs is that you simply pay fairly a bit extra per terabyte of storage. As know-how and manufacturing strategies enhance, the value of SSDs has and can proceed to drop.

5. How usually must you again up your knowledge?

As usually as doable, i.e. at roughly the speed that it modifications. That is very true in case you are engaged on an vital venture or have knowledge that you simply completely can't afford to lose. The important thing level right here is that in case your drive goes stomach up, the whole lot added since your final backup is toast.

You probably have your exterior drive related to your laptop always, it's a good suggestion to automate the backup course of and have the drive again up your knowledge because it modifications, or each hour or so. In any other case, join and again up at the very least as soon as a day. See our roundups of the most effective Home windows backup software program and the most effective on-line backup providers to study extra.

Even in the event you work along with your knowledge within the cloud, a neighborhood backup is an excellent concept. We all know of no main service that’s misplaced knowledge, however there’s at all times a primary time.

6. Why does Home windows say my exterior drive is smaller than specified?

That is due to the distinction between the binary and decimal quantity techniques, their nomenclatures, and a Microsoft miscue. Your 2TB drive certainly has two trillion bytes of storage, and in the event you have a look at the byte rely that Home windows shows in a drive’s properties dialog, this ought to be what you see. This, within the Worldwide System of Items (SI/decimal), is 2 terabytes, or 2TB. That is the usual language distributors use as shoppers are way more conversant in base 10.

Nonetheless, Home windows makes use of the newer Worldwide Electrotechnical Fee (IEC) binary multiples 2^10 (Kibibyte/KiB), 2^20 (Mebibyte/MiB), 2^30 (Gibibyte/Gib). Binary multiples are bigger numbers (one KiB is 1,024) so when Home windows divides the full bytes by the IEC system, the you get one thing like 1.8TiB for a 2TB drive. Alas, Home windows labels this as 1.8TB, deceptive the person.

Different causes you won't see as a lot accessible storage within the properties tab are formatting or partitioning. The file system makes use of some storage for file location and dimension data, and so forth. Additionally, some drives include a small partition containing software program so the principle partition shall be smaller than the drive’s whole capability.

7. How lengthy will my exterior drive final?

The lifespan of an exterior exhausting drive may be anyplace from three minutes to 10 years or extra relying on make and mannequin, in addition to the quantity of use and working setting. They’re mechanical units topic to put on and vulnerable to shock harm, so they need to be stored cool and handled gently. Reliability has elevated dramatically over the past decade.

Alas, judging the probably lifespan of an exterior exhausting drive is a crap shoot. In fact examine the guarantee, however the MTBF (Imply Time Earlier than Failure) quantity is usually thought of fantasy throughout the trade. Peruse person suggestions which might present perception into long run utilization, and maintain your ears peeled for unusual noises, your fingers crossed, and don’t drop the factor! Our greatest guess is that it is best to get at the very least 5 years with cautious dealing with.

SSDs don’t put on out or break mechanically, however their cells can solely be written to so many occasions. SSDs usually have a TBW (terabytes that could be written) score, however that is not often supplied by distributors for exterior SSDs. Trace: They might not use the identical SSD inside all through the product lifespan.

Most inner M.2 NVMe TLC SSDs are rated for round 600TBW per terabyte, and QLC varieties for round 200TBW, although the kind of NAND in use can also be not often supplied by distributors. That’s a variety of knowledge, and a variety of SSDs are rated properly under what they may obtain. You may guesstimate through the use of a utility to see how a lot knowledge you write to an SSD a day after which doing the maths.

Exterior SSD warranties are usually between three and 5 years, however as with all such issues, it’s a monetary threat calculation for the corporate. As is the TBW. Our greatest guess primarily based on expertise is maybe a decade. Nonetheless, sure fashions have had points lengthy earlier than that — usually on account of a flaw or failure within the bridge chip or controller.

8. How do exterior drives fail?

There are a couple of of ways in which an exterior exhausting drive may fail. The motor may stop, the learn/write heads may crash into the platter floor on account of shock whereas working, or the electronics may overheat and go stomach up. You may get a warning within the type of unusual noises resembling a scraping or grinding sound. If the info is especially vital, flip it off instantly and name a restoration service. That scraping sound stands out as the coating on the platter being eliminated by a crashed head. That is unrecoverable. For those who maintain operating it, again it up instantly and change it.

SSDs usually go stomach up as a result of more and more uncommon controller failure, which is a comparatively simple repair/reset for somebody who is aware of the SSD’s internals resembling a restoration service. SSDs will even ultimately put on out, although this solely precludes additional writing to the unit. You may nonetheless learn what’s on the drive, so it’s not the catastrophe a HDD failure may be.

9. What’s the quickest exterior interface?

So as, the quickest PC exterior interfaces are at present: 80Gbps Thunderbolt 5, 40Gbps USB4/Thunderbolt 3 and 4, 20Gbps USB 3.2×2, 10GBps USB 3.2, then 5Gbps USB 3.x.

10. What’s probably the most suitable exterior interface?

So as of compatibility: USB4, Thunderbolt 3/4/5, USB 3.x, USB 3.2×2, USB 3.x, USB 2, and USB 1.1.
