What you might want to know before you purchase
Sure, USB4 will present the identical large throughput as Thunderbolt 3 at decrease costs finally, and certain way more merchandise too.
Capability and worth
For many shoppers, the principle buying considerations for exterior storage are capability and worth. Nevertheless, when you may assume that the lowest-cost drive supplies probably the most worth, it usually doesn’t. In truth, greenback for greenback, cheaper low-capacity drives are most frequently the worst deal traditionally. We’ve been doing this comparability for years and it’s at all times been the worst worth.
You possibly can see that under the place we examine the favored WD Components desktop arduous drive’s obtainable capacities and costs. You’re paying greater than twice as a lot for the lowest-capacity drive versus the following step up. It’s nearly equally as unhealthy on the WD Components Moveable drive.
How a lot capability do you want?
The perfect “value” are usually for the most important arduous drives as you possibly can see, nevertheless it brings significantly greater costs and never everybody wants that a lot capability. So how a lot do you want? We advocate a backup drive not less than twice as giant as the full capability of your PC. You probably have 1TB of storage in your PC, 2TB will mean you can make a full backup whereas conserving historic backups on the identical drive. Having extra storage permits you to preserve extra historic recordsdata must you want them or use the identical drive to backup extra PCs.
Whereas the desktop drive supplies a far greater capability, in addition they require extra cables, weigh extra, and customarily is probably not fairly as shock resistant as a transportable arduous drive that’s designed to take a number of extra bumps, even when on.
The worst worth for an exterior arduous drive is often the lowest-capacity drive.
IDG
Interface
The overwhelming majority of exterior drives at present are USB drives. Past that straightforward assertion, the story will get complicated—largely due to the plethora of variations: USB 3.0, USB 3.1 Gen 1 (5Gbps, which is principally USB 3.0), USB 3.2 Gen 2 (10Gbps), and USB 3.2 Gen 2×2 (20Gbps), and now the up-and-coming USB4. In an try and simplify issues, the USB Discussion board has lately modified the nomenclature to point throughput pace—SuperSpeed USB 5Gbps, SuperSpeed USB 10Gbps, and SuperSpeed USB 20Gbps—as a result of efficiency is a precedence for many makes use of. For the sake of brevity (and sanity), we usually shorten these names to USB 10Gbps, or 10Gbps USB, for example.
No arduous drive, except mixed in RAID with others, can outstrip the 5Gbps (roughly 500MBps real-world after overhead) throughput of USB 3.1 Gen 1. Don’t fear about Gen 2, 10Gbps, or Thunderbolt with single arduous drive enclosures as a result of it doesn’t actually matter.
The place SuperSpeed 10Gbps/20Gbps, USB4, or Thunderbolt will certainly assistance is with the aforementioned RAID arduous drive setups, or extra probably—an SSD. The excellent news is that whereas USB 3.1 Gen 2, which is greater than quick sufficient for many customers at 10Gbps, was once costly, it’s principally the usual at present. A SanDisk Excessive Moveable SSD, our runner-up for moveable storage, might be had for $90 in a 500GB capability.
The sooner USB 3.2 SuperSpeed 20Gbps (Gen 2×2) strikes you right into a higher-price bracket, with the Seagate Firecuda Gaming SSD costing $200 for a similar 500GB of storage. Though sooner than the everyday USB 3.2 SuperSpeed 10Gbps, there aren’t a number of USB 20Gbps gen 2×2 ports on the market, however these drives ought to work with the upcoming USB4 on the similar 20Gbps tempo.
Thunderbolt 3 and the newer Thunderbolt 4 usually are the highest-performing interfaces for exterior storage, with the important thing limitation being a premium worth and a common lack of compatibility with the way more fashionable USB 3.2 ports on this planet. Nonetheless, if you need probably the most efficiency, you will get it in drives reminiscent of our advisable moveable, the Samsung Moveable SSD X5, which is $200 for 500GB of capability. For comparability, a slower 1TB Samsung T5 on USB is barely $125.
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 Kind C.
Ports
Exterior drives include quite a lot of ports, although they’re progressively consolidating on the Kind-C connector. Right here’s what you might want to care about:
USB 3 Micro-B Superspeed. That is nonetheless a quite common port on many lower-cost moveable and desktop exterior arduous drives at present. It’s truly the identical Micro USB port used in your cellphone, however beefed up with extra knowledge traces to hit USB 3.0 speeds. It’ll do 5Gbps and is okay for arduous drives and SATA (internally) SSDs.
USB 3 Kind-B is the bigger, blocky model of USB 3.0 Micro B. Kind B ports have gotten uncommon, although you may discover one on enclosures supporting 5.25-inch arduous drives or optical drives. It helps speeds as much as 5Gbps.
USB-C is the newest of the USB connectors the world is coalescing round. You see it in every thing from telephones to laptops. Consider, USB-C refers solely to the connector itself. What’s carried over the wires varies significantly. For instance, for knowledge transfers from an exterior drive, a USB-C port may imply every thing from USB 2.0 Excessive Pace (480Mbps) to USB 3.2 SuperSpeed 20Gbps in addition to USB4 and Thunderbolt 3. Any greater efficiency port at present ought to be USB-C—simply keep in mind that simply because it’s USB-C doesn’t imply the precise electronics contained in the PC or drive can hit the very best speeds of what a USB-C port can do.
USB Kind-A You received’t discover this port on any drive, however you can find this acquainted rectangular port on PCs and laptops. The explanation we point out it’s that any drive with a Kind-C port ought to include a Kind-C to Kind-A cable or adapter, hopefully, since most PCs have these.
Thunderbolt 2 is at this level, a useless port. Utilizing the mini-DisplayPort connector, it solely actually gained reputation on Macs, and even Apple put it out to pasture in 2017. There’s no must put money into a Thunderbolt 2 drive except it’s for legacy help points.
Notice that Apple makes a bi-directional Thunderbolt 1/2 to three adapter if you might want to join the one to the opposite. It doesn’t switch energy, nevertheless, so you possibly can’t apply it to its personal with bus-powered exterior drives. You’ll want a powered dock for that.
eSATA is one other legacy port that’s principally disappeared. Created for attaching exterior storage to your laptop’s SATA bus, eSATA was an affordable approach in its day to get past the 60MBps efficiency of USB 2.0. USB 3.0 put the final nail in its coffin. As with Thunderbolt 2, the one motive to put money into an eSATA drive is to be used with older computer systems.
A second drive as backup?
In backup, there’s a basic maxim appropriately named the Rule of Three. It states that it is best to at all times keep three copies of your irreplaceable knowledge: the unique knowledge, a backup, and a backup of the backup. Ideally, the 2 backups are stored in separate places, one being offsite. Conserving a replica on-line is nice for smaller quantities of knowledge and positively meets the offsite standards. Nevertheless, for huge photograph, audio, and/or video collections, exterior drives in pairs (or extra), are a sooner, extra sensible resolution.
Create full backups alternately to the 2 drives each few months. True patrons of knowledge may even take the second drive to work, so there’s no probability of shedding each drives to the identical native catastrophe.
For extra steerage on constructing out one of the best backup plan potential, see our roundups of one of the best cloud backup providers and finest Home windows backup software program.

Exterior drive FAQ
What’s the distinction between an SSD and an HDD?
HDDs (arduous disk drives) have been round for greater than 50 years and depend on spinning disks to learn and write knowledge. They’re basically composed of spinning steel platters with magnetic coatings the place the information is saved and a learn/write arm that strikes throughout the platters to entry the information.
SSDs (stable state drives), alternatively, use flash reminiscence and haven’t any transferring components contained in the drive. Knowledge is as an alternative saved on flash reminiscence microchips that are interconnected with each other. This interconnectedness permits for knowledge to be pulled from many various locations directly and considerably will increase reminiscence learn speeds.
Typically talking, SSDs might be a greater wager for an exterior drive as a result of their smaller measurement, sooner speeds, and total sturdiness. The principle disadvantage to SSDs is that you’ll pay more cash for a similar storage capability as HDDs. As expertise improves nevertheless, the value of SSDs will proceed to drop.

So a producer’s arduous drive that claims to have 1TB of storage truly has solely 931.31 GB of storage. It’s basically a rounding error that producers neglect to promote as a result of spherical numbers are simpler to grasp.
Another excuse that precise storage could seem lower than marketed is that arduous drives need to be formatted to learn and write knowledge correctly. When formatting, a portion of the cupboard space on the drive is allotted so as to catalog the information.
How lengthy does an exterior arduous drive final?
The typical lifespan of an exterior arduous drive is about three to 5 years. Nevertheless, that is extremely dependent upon the make and mannequin and the circumstances of utilization and storage. The extra you employ an exterior hard-drive, the much less dependable it turns into.
One approach to guesstimate the lifespan of your hard-drive is to take a look at the producer’s guarantee and the TBW (whole terabytes written) quantity. You possibly can decide the estimated every day quantity of storage you write after which extrapolate from there to see how lengthy you possibly can proceed to make use of it on a regular basis till you attain the TBW. These numbers will not be completely dependable, and drives can final for much longer than these two values, however they provide an thought as to when you might start to come across points.
How do exterior arduous drives fail?
