Silicon Power Armor A66 Review Listing

(Image credit: Future)
(opens in new tab)
Best large capacity rugged hard drive

Specifications

Capacity: 1TB, 2TB, 4TB, 5TB
Interface: USB 3.2

Reasons to buy

+
Cheapest high capacity rugged hard drive
+
Built-in cable storage

Reasons to avoid

-
No IP68 rating

The Silicon Power A66 5TB portable, rugged hard drive nicely brings three critical attributes in anyone’s quest for storage perfection: It is significant. In terms of sheer capacity, it is relatively inexpensive compared to other rivals (like the Sandisk Professional G-Drive ArmorATD (opens in new tab)). It will protect your data better than most external hard drives if you don’t intend to immerse it in water (it is only IPX4 rated). 

The A66 doesn’t come with any bundled software, and the cable it comes with is a special one (Type-A both ways, which makes replacing it problematic). In actual world tests, it performs in line with the rest of the HDD-based competition; expect to spend far more on a rugged SSD if you want something speedier, more resilient, smaller, and which can be used with a mobile device.

'Extreme' design may not appeal

Offered in four color styles - each as bright as the next - the Adata HD710 (opens in new tab) is an eye-catching, rugged hard drive. It's also one of the best, thanks to a durable case made of a unique silicone material that includes military-grade shock resistance and is waterproof and dustproof. 

As the advertising and product shots suggest, this device has been designed firmly with the outdoors in mind. It can withstand being submerged in up to two meters of water for up to 60 minutes, can handle drops of up to 1.5 meters in height, and boasts IP6X total dust-tight protection and G-shock vibration sensing technology.

Given the reassurance it provides as to its robustness, it's also helpful that it also provides a healthy 1TB capacity, meaning it also comes with no shortage of storage space.

Could be faster

Western Digital’s G-Technology brand is no stranger to ensuring that your data is kept safe, and G-Technology ArmorATD does so by offering several layers of physical protection. 

It features a rubber sleeve and a solid aluminum enclosure and is available in 1TB to 5TH versions. It boasts three layers of shock resistance and is crush resistant for up to 1000lb weight, making it a top companion for anyone who’s always out battling the elements. 

The small print shows that this is valid for drops of up to 1.2m on a carpeted concrete floor for 1TB and 2TB capacities and up to 1m on a carpeted concrete floor for 4TB capacity. The latter has more platters which makes it a bit more fragile. Note that while it is rain and dust-resistant, it is not IP68, so don’t take it swimming with you.

Why are SSD so expensive?

Anthony Spence, Marketing Specialist at Silicon Power (opens in new tab), answers this question

Solid state drives can seem expensive because they are costly to produce and have to compete with other components for production lines. One way of reducing cost has been to increase the number of bits per cell. 

This is a surefire way to reduce costs and increase capacity but it has considerably negative effects on performance, reliability and endurance, the latter being super important if you want to use your drives for Chia farming or as NAS drives.

Each additional bit makes it more time consuming to read and write from a cell, voltage needs also grow and so does power consumption. With higher voltage comes higher temperatures, which facilitate a phenomenon called electron leakage and might lead to data corruption.

Furthermore, every bit added to the cells increases the need for comprehensive error correction technologies. These solutions contribute to the maintenance of good data integrity, however they do so at the cost of higher latency and lower random performance (usually measured in IOPS).

Despite the drawbacks mentioned, the sizable reductions in terms of costs and an ever growing storage capacity make up for a fair trade off. Nowadays, most consumers can gain access to the blazing fast speeds of SSDs at very low price points, with in some cases prices starting from well under $100 for nearly 1TB (e.g. the Silicon Power PC60).

It is important to remember that NAND cells aren’t the only element that has an effect on flash performance, things like the interface being used, over-provisioning (dedicating a portion of the available storage to the controller), SLC caching, controller, inclusion of DRAM, among others also play an important role.

As most purchases, in the end it all boils down the consumer and its specific needs. Just as QLC wouldn’t make the cut for a 5G provider looking for storage options for their base stations, SLC solutions would be overkill for the average consumer.

How to choose the best rugged hard drives for you

Although it may seem daunting trying to pick the best rugged hard drive from such a vast selection, there are three simple ways to narrow down the field. 

Firstly, begin with budget. After all, if you've a set cost in mind you're not willing to spend a penny over, there's little point looking too deeply at devices that cost three times as much.

Once this has whittled down your choice, decide just how much storage you're going to require. If you're, for example, a full-time photographer or filmaker who regularly needs terrabytes of storage to backup your work on while out in the field, you'll need to look at the options that provide at least 1TB or 2TB of storage, possibly more.

Lastly, consider how and where you'll typically be using your hard drive. Presumably you're on the hunt for a robust and rugged version because you're either constantly on the move, working in the outdoors, or are just particularly clumsy. But does it need to be dust-resistant? Will it regularly be exposed to water? Consider these factors before making your choice on the best fit for you.

The best rugged hard drives: how we test

In order to make our selection of best rugged hard drives we took several key factors into consideration. Cost was chief among them, or rather, value, as we judged which hard drives offer the most for their price. 

As well as looking at each device's specs - such as storage capacity, portability, ease-of-use, connectivity options, and platform compatibility - we wanted to properly test the main selling point of each hard drive: its ruggedness. After all, if you're on this page, you're hunting for something that's going to last, even when severely tested.

And so we road-tested just how tough these hard drives are, analysing water and dust resistance, shock and drop proofing, and whether they boasted standardised certifications (such as IP68).
