Transcend StoreJet 25M3S – Rugged Portable Hard Drive


A normal portable hard drive might not last through harsh conditions like all the knocking and vibration, which isn’t a good thing for those who travels a lot – like me. I managed to get my hands on a rugged portable hard drive from Transcend, the StoreJet 25M3S which I’m really looking forward to.


Let’s start of with the packaging – there’s nothing much special to begin with, really. Other than the features offered and the cutout just for you to see how does the product looks like, that’s pretty much it for the front of the box.

Some technical details, supported storage service can be found at the back of the box, but you’ll have to try out the actual product to truly know how it works. And… That’s pretty much it with the box.

Inside the box, you’ll find these product catalogue which you’ll normally find included with most of the Transcend products, a user’s guide, the USB 3.0 type-A to micro-B data transfer cable and of course, the Transcend StoreJet 25M3S itself.

Comparison With Existing StoreJet 25MC

Now, I’m pretty sure some of you own the StoreJet 25MC as well. At first glance, the StoreJet 25M3S looks pretty much the same as the StoreJet 25MC. It even comes available in other choice of color such as the Iron Gray and Military Green.

Color aside, the StoreJet 25M3S inherited the same protection offered by all of its predecessor, the 3-stage shock protection design that is aligned with the MIL-STD-810G 516.6 U.S military drop-test standards. Something to take note is that the stated drop-test involves controlled environment such as drop from a height of 1.2m onto 2-inch plywood over concrete, not 2-storey fall from a building.

The one touch backup button is one of the prominent feature of the series, which can be found on the StoreJet 25M3S as well. It allows user to backup their data with just a single push on the button. All it requires is the initial configuration with the Transcend Elite data management software, which we will talk about it later.

Here’s where you’ll see the differences between both drives. Compared to the StoreJet 25MC, the StoreJet 25M3S has a thinner design for its enclosure, having a dimension of 129.5 mm x 80.8 mm x 16.1 mm and weighed at 185g. While it doesn’t seems to be too much of a deal, that slight difference in width (1.6mm) and thickness (2.7mm) makes it easier to fit in storage compartment of backpack or even pockets on your apparels.

And here’s a quick comparison in size to my extra wallet. You can imagine how easy it is to find its way into my pocket with ease.

The Software – Transcend Elite

I believe that a lot of users out there doesn’t really care about the software that comes with the portable hard drive itself, since it’s not really something that’s compulsory in order for you to operate the hard drive. The included software is more like an extension to the features of the hard drive itself, which some users would appreciate.

The Transcend Elite is probably the staple software for most of Trascend’s portable hard drive. Like I said earlier, the software isn’t a compulsory, but here’s a simple insight on what kind of benefit you’ll get with the Transcend Elite.

By having the software installed, you can configure it to work with the one touch backup button on the StoreJet 25M3S – yes, the software is required for the feature to work. Apart from backing up your important data to or from the drive, you can also backup your data to cloud storage services such as Dropbox or Google Drive. You can even encrypt your important data with its 256-bit AES file and folder encryption, which helps to prevent unauthorized access to your data by any users with malicious intent.

Protection Test

Instead of dropping it on plywood over concrete, I’ve actually tested it with a controlled test that is more suitable for our daily usage. My set of tests includes ‘accidental’ drop from a full tower PC case with height of 50cm and office table height of 70~80cm to wooden tiles.

Both of the height isn’t really that extreme compared to the 1.2m height stated in the MIL-STD-810G 516.6 U.S military drop-test standards, but I find it more reasonable to emulate the kind of ‘accident’ that happens around us during our daily work routine. I’m glad to say that it did manage to survive the controlled drop test, with the drive still functional without any issue.

Speed Test

For the transfer speed, the difference isn’t that much if you really were to compare it to most of the portable hard drive out there. As portable hard drive still uses a 2.5″ mechanical drive, you won’t really see any kind of blazing speed that’s able to go on par with a SATA SSD. Still, I would say that the speed is deemed acceptable.


For a 1TB rugged portable hard drive, I would say that the Transcend StoreJet 25M3S is the real deal. The speed isn’t really something that’s worth bragging about, but the protection design does. Surviving a 50cm drop isn’t something you’d see on most of the generic portable hard drive, let alone dropping from the height of 70~80cm.

For the price of RM 225, I don’t see any reason to not to recommend the StoreJet 25M3S to those who need this kind of extra protection for their data.
