The rugged, moveable DiskAshur M2 retains your recordsdata safe behind military-grade encryption with out requiring any fussy companion software program.

There are many advantages to storing delicate info digitally reasonably than as a bodily hardcopy. It is usually simpler to maintain observe of huge quantities of knowledge when you possibly can conveniently seek for them out of your desktop.

In the meantime, a file folder in your laptop can simply substitute a number of file cupboards inside your house or workplace.

Nevertheless, leaving info on a pc, your knowledge might simply be accessed by hackers or those that have bodily entry to your units. It could possibly be misplaced ought to the gadget be broken.

That is the place the DiskAshur M2 has you coated. It is a small, robust, exterior solid-state drive that options onboard encryption to maintain your private info protected and safe.

Dimension and design

The DiskAshur M2 is extremely small — it is 106mm x 45mm x 12mm — smaller however a bit thicker than a median iPhone. It weighs a scant 65 grams, or a few third of what an iPhone 11 weighs.

It encompasses a detachable laborious sleeve to stop unintended button presses and shield it from bumps and scratches.

In response to the producer, so long as the M2 is saved in its sleeve, it is crushproof for as much as 2.7 tons, and drop-proof as much as 12 ft. We dropped the drive onto a flooring from a top of some ft and had no points accessing the information later.

It additionally options an IP68 ranking, making it able to being submerged in as much as 5 ft of water for half-hour, and in a position to get up in opposition to mud, dust, and sand.

We love the small dimension, which inserts completely in a again pocket, tech bag, purse, or desk. Moreover, iStorage features a good laborious foam case with a wrist strap to hold your M2 round, serving to to guard it whereas in tow.

On the entrance of the DiskAshure M2 is a 12-button keypad that includes ten digits, a lock/unlock button, and a shift key. Customers might want to arrange a 7 to fifteen digit pin, which is used to unlock the drive — however extra on that later.

Connecting to your Mac, PC, USB-C iPad, or pill is simple. The producer consists of each a USB-C and a USB-A cable.

Whereas a pleasant addition, we predict these cables could possibly be slightly longer, particularly if you would like to attach it by way of a USB port on the again of your gadget.

General, the design is right for individuals who need extra storage with enhanced safety however need one thing small and discreet, too.


Just like the DiskAshur 2 we reviewed in 2019, the drive’s main safety characteristic is its Enhanced Twin Producing Encryption (EDGE) system. It makes use of a devoted safe microprocessor to encrypt and decrypt the information on the drive in {hardware}, with military-grade AES-XTS 256-bit encryption.

The system additionally encrypts the encryption key saved on the gadget and it is just used when a legitimate PIN is entered. Pins can encompass digits between 0 and 9, and an included shift key permits customers so as to add extra combos. For instance, 3056843 is completely different than 305(shift)6843.

Consumer-created PINs can’t include repeating numbers or be sequential, both. This guidelines out codes like 1234567 or 88888888 that could possibly be simply guessed.

The principle profit is that the whole system is self-contained. You will not want to make use of any companion software program to learn or write content material to the M2. When you enter the PIN, it will work identical to every other exterior drive.

When plugged into your gadget, the drive stays unseen till you enter the code. In case you flip off your Mac or disconnect the drive, it routinely locks.

In case you are usually forgetful and go away your computing setup unlocked for lengthy durations, you possibly can set the M2 to lock after a sure period of time, which, frankly, is only a sensible concept.

There’s additionally a built-in brute-force assault mode, routinely destroying the encryption key and all knowledge written to the drive after a number of consecutive incorrect makes an attempt. Customers can set the brute-force assault failure threshold themselves, too.

Moreover, a consumer can arrange a self-destruct pin that enables the consumer to rapidly destroy the encryption key and all knowledge by getting into a selected code. Whereas that is probably not a characteristic that the typical consumer would want, it is nonetheless a wonderful choice.

Studying and writing speeds

For the 1-terabyte SSD mannequin used for testing, iStorage claims it has learn and write speeds of as much as 370MB/s and 370MB/s, respectively. In checks utilizing a 2018 15-inch MacBook Professional, it undershot each these numbers significantly with 320.7MB/s, whereas writing knowledge continues to be respectable at 304.6MB/s when examined utilizing BlackMagic’s Disk Velocity Take a look at.


For many customers, this will probably be adequate sufficient. Moreover, the principle promoting level of the DiskAshur M2 is not its speeds however reasonably the onboard encryption and built-in safety keypad.

Excessive safety in a small bundle

In case you’re out there for an ultra-secure exterior solid-state drive, you may do loads worse than the DiskAshur M2. Its small dimension, coupled with the onboard encryption, makes it a protected option to journey with, and it is robust sufficient to face as much as even essentially the most clumsy of customers.


  • On-board encryption
  • Customers can arrange self-destruct and brute-force deterrents
  • Crush-proof, shock-proof, and water/mud resistant
  • Light-weight, small


  • Learn and write speeds is probably not helpful for these capturing or enjoying massive video recordsdata
  • Brief wire makes plugging the M2 into desktops awkward

Score: 4 out of 5

The place to purchase

Anybody can buy a DiskAshure M2 from NewEgg, the place the 1-terabyte mannequin we examined will run you $319.00. Additionally it is out there in 120GB, 240GB, 500GB, and 2TB sizes.
