StoreJet 25M3 2TB Rugged Portable Hard Drive, Military Grade Shockproof, USB-A 3.1 Portable HDD for PC, Mac & Laptop, Iron Gray TS2TSJ25M3S

This has been, far and away the most reliable external hard drive I have ever owned - and I have had a number of them over the years. I travel with one and a laptop often and it gets bashed around, yet never misses a beat. I have had it so long that i don't even remember when I bought it. Don't hesitate.

I've been using the Transcend StoreJet 25M3 4TB for several months now, and it's proven to be an outstanding portable storage solution. The build quality is immediately apparent - the military-grade shockproof casing feels robust and reassuring, giving me complete confidence when transporting it between locations. The storage capacity is superb. With 4TB available, I can store extensive datasets, backup files, and multimedia content without constantly worrying about running out of space. Transfer speeds via USB-A are reliable and consistent, making it efficient for both regular backups and accessing large files on the go. What really stands out is how practical it is for daily use. Despite its rugged construction, it remains compact and lightweight enough to slip into a bag without adding significant bulk. The rubberised outer casing provides excellent grip and protects against accidental drops - something I've unfortunately tested, and the drive came through unscathed. For anyone needing reliable, portable storage that can withstand the rigours of regular transport, the Transcend StoreJet 25M3 delivers on all fronts. It's become an essential piece of my workflow, and I wouldn't hesitate to recommend it to colleagues working in demanding environments.

Bought on special offer, so great value and very reliable.

Got it with special offer, good balue for money, seems solid and well made. Speed wise is good, but is slighly slower than my other external WD hard drive (that is wired to the electricity) but still ok.

Really good in everything.

Great product,fast ,true to price and portable.

I bought mine 4½ years ago to store drone footage and still going strong. I was going to buy another as a back up for it but it's now over 3 times the £40 I paid back then.

Over the years, I’ve learnt the hard way the importance of backing up files to external hard drives. I’ve used Transcend portable hard drives for over ten years, and none of them has ever failed. With MS pc’s, the Transcend 25M3S is good to go straight out of the box: just plug it in. With Apple Mac’s, you’ll need to format the 25M3S first. If you’re familiar with this process, you’ll know that it’s a 10-second doddle. For those who aren’t, I’ve posted six step-by-step screen shots of what to do. WARNING – formatting will wipe your external hard drive clean, so do this only with a brand-new unit. If you’re using an old external hard drive, make sure you’ve already saved everything on it somewhere else. Formatting procedure. 1. in the Finder window, search for ‘Disk Utility.app’. 2. Double click on Disk Utility.app to open it. 3. Highlight Transcend in the left-hand margin. For safety, I renamed my Transcend as ‘Transnd MAC’ and unplugged everything else. 4. Click on ‘Erase’ – that’s the centre icon at the top of the Disk Utility window. That opens a sub-menu box. 5. Choose ex-FAT in the Format box. 6. Click on ‘Erase’ (Bottom right) That’s it. Your 25M3S is now ready to use on your Apple Mac. You can either drag existing files from your iMac to your Transcend, using your Finder window or simply save new files directly to your Transcend.

MacのTimemachine（バックアップ）用に購入。毎日、定時でバックアップしていますが数ヶ月経過した時点では何の問題もなく動作しています。表面のゴムカバーも落下時の耐衝撃と守った時の滑らない感じがして良いです。 コードはUSB-Cの機器に接続できます。

This is the second unit I have bought and found the setup very easy, just plug it into your computer USB port, give it a few moments to connect, and you are ready to start transferring images, Excellent storage capacity, and useful to have all your files saved to a quickly detachable exterior drive.

Good design.

Es resistente,buena capacidad y durabilidad.Es el segundo que tengo y compro por el buen resultado que me ha dado.

Nice product, working as expected
