When making the picks for our most fulfilling exterior challenging drive ebook, there were loads of elements we considered. pace, build great, fee and support have been at the forefront of our minds, whereas every other elements, similar to reliability, took a backseat. in this guide to the surest exterior tough power, we’re going to remedy that concern. 

With this diverse focal point, we will hone in on the drives so that it will stand the examine of time, both when it comes to efficiency and build great. We’ve picked 5 alternatives from our external challenging pressure experiences that give protection to your data internally and externally, and present outstanding pace within the technique. 

finding authentic hard drives is extra intricate than it would look, though. earlier than attending to our picks, let’s speak a bit bit about how we made our selections.

foremost exterior challenging force 2019 opting for the premier external complicated pressure

There’s plenty that goes into settling on a authentic external hard drive. The disk internal is the first element of subject. besides the fact that children there has at all times been, and all the time should be, version in hard drive manufacturing, there are some numbers we are able to go on. 

Backblaze, as an example, offers a quarterly abstract of the pressure failures it experiences with its unlimited on-line backup provider (examine our Backblaze evaluation). 

we can’t draw a straight line from that to its external difficult drives, as Backblaze is noting the drive failures among disks made for mass storage, but there are just a few commonplace conclusions we can draw. 

for instance, Backblaze says in its latest record that it has retired all Western Digital hard drives, replacing them with HGST drives, which is owned by Western Digital. one more universal notice is that Seagate drives are a little extra more likely to fail than Toshiba drives. 

That’s only one piece of the puzzle, notwithstanding. We also regarded the classification of power itself. natural spinning difficult drives are lots greater likely to fail than solid-state drives. SSDs use memory chips, flashing the facts throughout the PCB, whereas tough-disk drives use magnetic storage, which reads and writes information to a sequence of platters. 

since SSDs have no relocating components, there’s an awful lot much less room for failure. The simplest difficulty with SSDs is when information is written and deleted from the identical component of the force again and again once more. luckily, that situation can be solved with wear leveling, which most modern external SSDs consist of. 

With the inner considerations covered, we grew to become to the exterior. An exterior complicated force lives outside your laptop, so it will be able to deal with whatever thing you throw at it. We searched for drives that are constructed to face up to a beating, in contrast to the ADATA SD600 and Toshiba Canvio basics (read our ADATA SD600 overview and Toshiba Canvio basics overview). 

We didn’t ignore the hazard of cybercrime, both. besides attempting to find drives that covered themselves internally and externally, we also searched for drives that may give protection to themselves on the digital entrance. That includes hardware encryption and password insurance policy.

fast, authentic and rugged, the G-technology G-drive cell SSD ticks all the boxes when it comes to a powerhouse difficult drive. It’s a portable SSD, allowing you to take up to 2TB of content material on the go. greater importantly, notwithstanding, it’s constructed like a tank, guaranteeing the content material you are taking is rarely misplaced.


the exterior is humble adequate, but G-know-how has a whole lot insurance plan tucked just beneath the hood. The drive is IP67-rated for water and dirt insurance policy. The “6” is for dirt insurance policy, which capability the power is absolutely included from detrimental grime contact. That’s the optimum rating the foreign Electrotechnical fee supplies for the IP regular. 

The “7” is for water insurance plan, which is one step under the optimum rating (IP68-rated products are the best of the most suitable). in spite of this, you’re not helpless to a bit moisture. The ranking skill the G-drive mobile SSD will still characteristic after being submerged in up to 1 meter of water for as much as 30 minutes. 

so far as the IP usual goes, the G-force mobile SSD is near the good. additionally, G-power packs in drop- and drive-coverage. Even when functioning, the pressure can address up to a 10-foot drop and 1,000 kilos of power. 

different motives We like the G-expertise G-drive cellular SSD

The G-force cell SSD is in a class of its personal now not handiest when it involves coverage, however additionally when it comes to velocity. It’s one of the quickest external tough drives we’ve established, clocking in with a sequential study speed of MB/s, a sequential write velocity of MB/s, a random examine pace of MB/s and a random write speed of MB/s. 

Sequential performance is solid, but we’re extra impressed by the random performance. in keeping with our outcomes, the pressure is capable of read and write statistics very instantly to varied locations on the memory modules. throughout our palms-on check, we seen it in action, with the G-force cell SSD transfering a folder at a rate of a hundred and forty four MB/s. 

every thing the G-technology G-power cell SSD does, it does well, however’s missing in a single enviornment. G-know-how doesn’t include hardware encryption or password insurance plan. youngsters disappointing, the different areas the pressure gets appropriate overshadow the shortcoming of encryption. which you can read our full concepts in our G-know-how G-power mobile SSD assessment.


  • dirt & water-resistant
  • purchasable as much as 2TB
  • Very fast
  • The Samsung T5 isn’t legit in the identical means as the G-pressure cellular SSD. It’s constructed smartly, but it doesn’t come with any IP certification (Samsung could have its second there somewhat later). youngsters, the draw to this drive isn’t uncooked coverage. It’s the undeniable fact that Samsung has managed to make a portable disk that’s professional and delightful. 

    It comes in 250GB, 500GB, 1TB and 2TB. the first two models are available in a light blue, whereas the 1TB and 2TB variations ship in jet black. each models, besides the fact that children, feature an all-metallic shroud that, while robust, is light-weight. The T5 weighs best 51 grams and measures 74mm by way of fifty which is smaller than a company card. 

    however an abundance of dangerous grime and water will make short work of the T5, it’s covered from falls due to the strong-state indoors and metal casing. it may likely handle an honest quantity of drive, too, but Samsung doesn’t put any requirements on that. additionally, the T5 protects you on the digital front. in the event you first plug in the pressure, you’ll be prompted to installation Samsung’s management utility. There, you’ll be asked to set a password. When the drive isn’t unlocked, your whole facts is encrypted with AES-256 (study our description of encryption to be taught greater about that).

    different causes We like the Samsung T5

    like the G-pressure mobile SSD, the T5 is terribly quick. Sequential performance is a bit better, with a study velocity of MB/s and a write speed of 520 MB/s, however the random efficiency is greater amazing. although slower on random reads, the T5 is faster than the G-force cell SSD when it involves random writes, measuring at MB/s during our testing. 

    however we didn’t point out support, that may well be regarded a side of what makes an external difficult force respectable, and on that front, the T5 is brilliant. as a result of Samsung manufactures lots of items, it has a strong guide system already in region, supplying you with diverse alternatives to locate solutions to any questions you may additionally have. 

    As our most excellent external tough power for Mac and ultimate SSD external challenging pressure, it is going to come as little surprise that we tremendously recommend the Samsung T5. that you may be trained why it’s our favorite disk in our Samsung T5 overview.


  • Compact
  • lightweight
  • Very quickly
  • The SanDisk extreme transportable is made for, neatly, excessive cases. The compact, pocket-sized design points a hole for a carabiner and a delicate-rubber conclude, which will prevent the drive from slipping on surfaces. despite the fact, it’s additionally there to provide the IP55-rated dust and water protection.

    As outlined, the first quantity in an IP score is for filth and the 2nd number is for water. On the filth entrance, the SanDisk severe moveable is neatly included. As per the IP score desk, “ingress of grime is not totally avoided,” but the operation of the pressure gained’t be intruded upon even beneath total contact with dangerous dust. 

    Water insurance policy is less surprising, notwithstanding nevertheless not unhealthy. The SanDisk excessive moveable can’t address full submersion, but it surely can handle potent water jets with up to a (about half an inch) nozzle from any direction. In follow, a small spray of water or brief drop shouldn’t be an argument. 

    moreover, the force is shock- and vibration-resistant, and is derived with password insurance policy. The protected SecureAccess application will will let you encrypt facts to your power with AES-128. however a smaller key dimension than considered on the Samsung T5, the power of AES should still be adequate to keep your information secure. 

    other factors We like the SanDisk extreme moveable

    velocity is, unsurprisingly, excellent with the SanDisk excessive moveable. We noted sequential read and write speeds above 500 MB/s and random reads and writes close 160 MB/s on our 250GB examine model. It’s slower than the Samsung T5 and G-drive cell SSD, but simplest just a little. 

    It could be a whole lot sooner, though. in addition to the smooth-rubber edition, SanDisk also sells an aluminum version of the severe transportable. It’s lots greater costly, nevertheless it utilizes a NVMe SSD internal, transferring information over USB Gen 2. With that setup, the aluminum version — which is simply purchasable in a 500GB capacity — can read sequential examine speeds of as much as 1,050 MB/s. 

    if you’re on the go and want an external power that may deal with a beating, the SanDisk intense portable is for you. It’s slightly slower than the T5 and G-drive, nevertheless it’s additionally a whole lot smaller and lighter. that you could learn more about the force in our SanDisk intense transportable evaluation.


  • lightweight
  • IP55-rated
  • quick
  • Cons:

  • Dated encryption utility
  • We said Samsung would have its time in the highlight for construct great, and the X5 is it. The X5 is Samsung’s no-compromises exterior SSD, combining dazzling construct pleasant with one among Samsung’s quickest NVMe SSDs. it is obviously the better of the most advantageous, but it surely comes with a cost tag to suit.

    The pressure is attainable in 500GB, 1TB and 2TB capacities, with the 2TB model clocking in at greater than $800. That money doesn’t go to waste, though. The NVMe SSD interior can carry sequential reads of as much as 2,800 MB/s and sequential writes of 2,300 MB/s, making all of the aforementioned SSDs seem like a comic story. 

    It’s built like a tank, too, however you can also now not comprehend that at the start. Samsung drew inspiration from activities automobiles with the design, the use of a sleek, glossy gray desirable with red accents right through. simply below the floor is a magnesium-alloy body and a heat sink as a way to maintain the power beneath 45 levels Celsius all through operation and offer protection to it from an up to two-meter fall. 

    furthermore, the X5 is protected with the equal AES-256 encryption that protects the T5. if you install the pressure, you’ll be brought on to deploy Samsung’s software and set a password. From there, that you would be able to lock down your force, verify for firmware updates and turn off encryption, should you choose. 

    other reasons We just like the Samsung X5 portable SSD

    with a view to carry such high pace, the Samsung X5 uses a Thunderbolt three connection. although Thunderbolt three uses a USB-C plug, it isn’t USB Thunderbolt three presents four instances the bandwidth of USB which is needed for the extremely-quickly transfer prices of the X5. 

    Any contemporary Mac has at the least one Thunderbolt 3 port, so Apple clients are covered. issues get messy with windows, although. Thunderbolt is an Intel expertise, and up until recently, companies needed to pay to license it. Intel has given that made Thunderbolt three royalty free, however no AMD motherboards up to this aspect have built-in it. 

    briefly, if you’re the use of an Intel-primarily based equipment — which means you have an Intel processor — remember to be in a position to use Thunderbolt three. If on AMD, you’ll need to wait except a brand new batch of motherboards are released. It’s a hassle, however given how quick the Samsung X5 is, it’s a hassle that’s value coping with.


  • extremely quick
  • strengthened with a magnesium-alloy frame
  • developed-in heatsink
  • Cons:

  • Very expensive
  • restricted to Thunderbolt three
  • LaCie is accepted for making awesome, creator-concentrated challenging drives. The Rugged collection, that includes the identical desirable silver drives and iconic orange shock absorber, are developed to permit creatives to take records at any place they go and have it continue to exist after the fact. although the drives are very costly, that you would be able to get coverage for fairly low-priced with the Rugged Mini. 

    It’s a spinning difficult power, equivalent in measurement and performance to anything like the Seagate Backup Plus portable (study our Seagate Backup Plus portable assessment). despite the fact, it’s developed a whole lot greater than those drives. The construct best offers drop insurance plan of up to 4 feet, rain resistance and drive coverage of up to one ton. 

    in comparison to probably the most SSDs above, the coverage isn’t that dazzling. in comparison to other spinning challenging drives, notwithstanding, it is. As mentioned above, spinning disks are at a drawback in terms of reliability with no trouble by way of how they’re designed. With the LaCie Rugged Mini, though, you’re getting an identical coverage. 

    both-12 months restrained assurance shouldn’t be unnoticed, both. youngsters restrained warranties are constantly just to give protection to towards manufacturing error, the Rugged Mini protects towards records loss, too. with your power, you’re eligible for one in-lab statistics restoration effort as long as you’re inner your assurance window. 

    different causes We just like the LaCie Rugged Mini

    efficiency-sensible, the LaCie Rugged Mini isn’t superb. It’s actually superior with reads than writes, with a sequential examine pace of MB/s and a random read pace of MB/s. Random performance is poor, with the Rugged Mini clocking in a random study velocity of MB/s and a random write velocity of MB/s. 

    youngsters, the focal point of the power isn’t on performance, it’s on protection. It’s comparable to different blackbox exterior challenging drives we’ve reviewed, such because the Western Digital aspects (study our Western Digital points evaluation). 

    in contrast to these drive, notwithstanding, the LaCie Rugged Mini isn’t built with an affordable, plastic shroud. If that sounds like something you’re drawn to, make certain to study our LaCie Rugged Mini evaluate.


  • Shock resistant
  • purchasable up to 4TB
  • cost effective
  • ultimate options

    Reliability is critical when it comes to exterior difficult drives. all of the options above will operate for years to come back, even below the harshest circumstances. typical, the G-technology G-force cell SSD presents the finest balance of speed, coverage and value. in case you’re willing to spend extra cash, though, the Samsung X5 is a great alternative. 

    The T5 and excessive transportable are only variations of the G-drive mobile SSD. They present equivalent performance, a slightly lessen price and just a little less insurance policy. in case you don’t plan on taking your exterior complicated power mountain climbing or throwing it into a lake, although, they’ll work simply first-class.
