When the Silicon Energy Armor A85 arrived, a number of people bought excited by the notion that we’d been despatched a hip flask containing some uncommon libation. Sadly, we had not.

It turned out that whereas being the tough dimension and form of that specific receptacle, the Armor A85 is definitely an exterior laborious drive which is constructed to be abused past all affordable expectations. The 1TB mannequin we reviewed retails at round £78 in the UK, $75 within the US, or should you’re in Australia, it’s going to set you again about AU$109 (drive capacities go as much as 5TB on the top-end).

Design

There are solely two gadgets within the packaging: the Armor A85 itself and a brief (32cm) USB cable that has Sort-A superspeed connectors at each ends.

The benefit of this design is rarely worrying about which finish to plug in. Nonetheless, this structure isn’t a typical USB cable, so misplacing it would show problematic.

Silicon Energy’s method to avoiding that state of affairs is to make the be part of between the black cap and silver steel part a thick rubber band that you should use to carry the cable.

We’re unsure how effectively this may work in apply, however not less than the producer thought of that cable loss might be a difficulty.

The USB Sort-A port on the drive is hidden below a thick plug on the black cap finish that comes with a good rubber seal. The plug appears to be like good for protecting undesirable water and grime out of the drive, but it surely’s additionally a superb path to breaking a fingernail attempting to pop it out.

The temptation could be to depart it within the open state, however failure to switch it after use would undermine the power of the drive to deal with immersion, in fact.

A draw back of this stage of safety is that if the drive dies inside its cocoon, that’s the place it’s going to stay – no sensible means to extract it exists, not less than not with out an angle grinder.

Past these factors, there’s comparatively little to say about this design, apart from it’s constructed to deal with abuse relatively than win any model awards.

Constructed to outlive

On one stage the A85 Armor is only a laborious drive stuffed inside a thick steel tube.

Nonetheless, that pondering totally ignores all of the difficult technical particulars the Silicon Energy engineers needed to resolve to make that work. Like avoiding overheating points with the drive in an enclosed steel house, and cosseting the drive from unintended assaults of water, mud, and the overall trials and tribulations of careless possession.

The answer wasn’t delicate, and primarily concerned the creation of a gently curved aluminum tube and a rubber sleeve that isolates the drive from no matter is going on bodily to the outer case.

The engineers additionally created a suspension system that isolates the exterior connector from the floating inside laborious drive, an apparent level of potential failure.

Engineered on this trend, the Armor A85 survived the MIL-STD 810G Methodology 516.6 Process IV, aka the transit drop take a look at. And Silicon Energy’s promotional materials claims it may face up to 500kg of power, ought to one thing unlucky occur to it.

The promo bumph additionally exhibits photos of a automobile on prime of the drive, although we should always level out that the majority automobiles weigh rather more than 500kg, even when the mass is distributed between a number of wheels.

As tempting as driving over the machine a number of instances earlier than benchmarking was, the three-year guarantee and its potential to deal with MIL-STD 810G satisfied us that the A85 is hard in additional than the appears to be like division.

The transit drop take a look at is to carry out 26 drops on every face, edge, and nook from a top of 122cm above the ground. And all these take a look at drops can solely be divided amongst 5 take a look at gadgets. The machine should additionally survive a single 3m drop take a look at and nonetheless be useful afterwards.

Having compliance to IP68 on this context means the machine must be dust-proof and guarded in opposition to immersion in water for greater than 30 minutes at a depth of as much as 1 meter.

An inexpensive assumption for this take a look at is that the immersion would happen with the USB cowl in place, and due to this fact not linked to a different machine on the time.

Relating to endurance, the Armor A85 actually talks-the-talk, however can it walk-the-walk?

Efficiency

In earlier designs, Silicon Energy has used Seagate’s Momentus drives, and we suspect that’s what’s inside right here too.

We solely bought to check the 1TB mannequin, however as talked about beforehand, the identical outer shell is used with a spread of drives as much as 5TB. The one distinction, apart from the capability, is that the bigger variations are marginally heavier.

Efficiency isn’t SSD stage, but it surely’s greater than acceptable in comparison with many moveable drive options that use standard drive expertise.

CrystalDiskMark rated the learn pace at 119.3MB/s and the write pace at just a bit much less: 118.4MB/s. To realize these ranges you’ll want a USB Three.zero reference to USAP mode lively – it must be natively on any Home windows eight.x or Home windows 10 installations with the proper .

Usually, the suppliers of assessment tools to TechRadar Professional anticipate us to not deliberately abuse their machine as a result of they’d prefer it again sooner or later.

Nonetheless, the representatives of Silicon Energy particularly instructed us to get the A85 moist, and unbelievably, drive a automobile over it. So obligingly – post-benchmarking – we did.

Unsurprisingly, the automobile train did depart some minor abrasions on the Armor A85, but it surely didn’t cease working.  It additionally survived full immersion in water, although it’s value noting that it doesn’t float. That’s a difficulty as a result of dropping it right into a depth of greater than Three-foot may be catastrophic even when it may be efficiently retrieved.

So far as efficiency goes, the A85 does what it says on its relatively thick aluminum tin.

Remaining verdict

This isn’t the quickest exterior drive we’ve examined, however the Silicon Energy Armor A85 is undeniably one of many hardest. When you’re taking a visit the place knowledge loss may outcome from mud or water penetration, then the Armor A85 is an inexpensive resolution that may face up to loads of punishment (perhaps Black Friday will see its value lower additional, too).

The one important caveat is that the drive doesn’t float, so dropping it into something apart from shallow water might be its undoing with out some type of further technique of floatation being added.
