Best Rugged (Military Grade) Portable External Hard Drives

Protecting your data can be tough. Most hard drives are not built to withstand a fall. For most HHDs, a two-foot drop will almost certainly mean death. And these are the devices that are supposed to be protecting your data! In some cases, it can be like writing a business contract on a sheet of glass. Just one accident is all it takes.

Unless you’re willing to add some zeros to your budget, HHDs are still the most economical way to store data. Solid state drives are getting cheaper every year, but they’re nowhere near as affordable for large quantities of storage as HHDs. Unfortunately, HHDs are also fairly fragile by design because they use moving mechanical parts. So to protect one, you need essentially a full suit of armor to be applied to the drive.

You don’t need to be trekking through the jungle to be concerned about the fragility of your data. But if you are taking a bumpy journey, then you want the best protected external drive you can possibly find. Smartphone screen repair is a billion-dollar industry because people drop things. And while portable hard drives are slightly larger than smartphones, they’re just as likely to suffer a fall as anything else without handles and straps.

Choosing a Rugged Portable External HHD

For selecting a truly rugged HHD, you’ll want to know about some relevant performance tests. Military grade protection is mostly a fancy marketing phrase, but in some cases, the manufacturer is specifying a very specific standardized test by which their drive was tested.

There’s a world of difference between equipment that looks rugged, and equipment that’s built to take a spill. For selecting a hard drive with military grade construction, you need a device which was built to pass a military drop test known as MIL-STD-810G 516.6.

It’s a test which involves two-dozen drops into plywood, and devices which pass are built to survive at least a six-foot drop. But because no independent labs are doing this type of testing, it’s often useful to check these claims against reviews to see whether or not the construction actually lives up to the manufacturer’s claims.

Technical Considerations

Like with choosing any hard drive, you’ll want to understand about the performance of drive, including its ability to store and read data in a timely manner. Depending on your intended use, you might even care about the power consumption of the drive on your laptop battery. As is so often the case, it’s the small details that count most.

How much space do you need for your drive? If you’re not sure, aim for at least one terabyte of data. Speed considerations for drives are often a reflection of the type of cables you use. For instance, USB 3.0 connections are literally ten times faster than their 2.0 counterparts, and that speed plays out as you try and move files from one place to another.

But ultimately, your speed will be bottlenecked to HHD read/write speeds. A speedy 7,200 RPM drive will have a maximum read/write speed in the neighborhood of 100 MB/s. It varies from one hard drive to another, and will be the determining factor on speed more than USB cabling. In short, that means you don’t have to pay attention to USB speeds, only to which type of USB plug is used.

Making Safe Bets

Hard drives have an annual failure rate of about 3%. These figures vary slightly from one HHD manufacturer to the next, from one generation of drives to the next. But any drives which don’t have serious flaws will come close to having a standard 3% failure rate. In other words, if one hundred people buy a drive, three people are getting a dud that will be dead inside of 12 months.

That’s just a fact about hard drives. Unfortunately, the higher failure rate of these devices are often manifest in user reviews. How many of the unlucky 3% decide to complain their product failed? Whenever you’re looking at consumer reviews for hard drives, this is often important to keep in mind. To protect yourself from being part of that unlucky 3%, what you need to do is pay attention to the warranty provided by the drive’s manufacturer. The very least you should expect is a one-year warranty.

Transcend StoreJet M3

Transcend StoreJet M3

The Transcend StoreJet M3 is a USB 3.1 drive which makes use of military-grade shock resistance. It’s constructed with a distinct military aesthetic composed of green and iron gray. And it provides a bulky 1TB capacity, which should be suitable for virtually all data storage and transfer needs.

The generally rugged build of the Transcend StoreJet M3 gives off the impression you could take this drive into rugged terrain. But if you look carefully at the actual protection it offers, what’s provided is more in line with someone who wants to keep their data remotely backed-up.

Transcend StoreJet M3

Build & Design

Hard drives aren’t terribly large to begin with, but they can get a big bulky when you start wrapping them up in armor. The Transcend StoreJet M3 sits comfortably at 5.1 x 3.2 x 0.7-inches, which is a surprisingly slim profile.

For protection, it has a three-stage shock protection system. The first layer is the external anti-shock rubber case. The next layer involves the thick aluminum armoring over the device. And the final stage involves an internal, rubber-based hard drive suspension system.

On the outside of the M3, you’ll notice its single button, a quick reconnect button, which allows you reconnect a removed hard-drive without unplugging it. That button can also be used as a one-touch auto-backup feature from within the Transcend StoreJet M3 software.
