Customers say
Customers find the portable hard drive to be well-built, with one noting it has never failed in ten years of use, and appreciate its storage capacity, with one mentioning it can store thousands of digital images. They praise its portability, ease of use, and value for money. The functionality and transfer speed receive mixed reviews – while some say it works flawlessly and is incredibly fast, others report it failing after one day and being extremely slow.

Best on the market
I have been a lover of Transcend Storjet drives for at least 10 years if not closer to 15. I only buy these when I can for my use and that of my customers. Hard drives do not like vibration. They don’t even like being put on a desk in the normal way. These are protected by a rubber case, a damping system and a rugged case. Trust me they last. I had a shop and we would share these to do customer backups. We were not careful with them and they lasted me a good 7 years each. I sold some to a mate who blue tacked his to his desk and that is where they stayed. 12 years later still going strong. Never buy external HDDs (not talking SSD here) that come in plastic cases. They don’t last. These do! The sad thing is that they are becoming harder to get.

Brilliant. Never failed in ten years. Needs formatting for Mac
Over the years, Iâve learnt the hard way the importance of backing up files to external hard drives. Iâve used Transcend portable hard drives for over ten years, and none of them has ever failed.
With MS pcâs, the Transcend 25M3S is good to go straight out of the box: just plug it in.
With Apple Macâs, youâll need to format the 25M3S first. If youâre familiar with this process, youâll know that itâs a 10-second doddle. For those who arenât, Iâve posted six step-by-step screen shots of what to do. WARNING â formatting will wipe your external hard drive clean, so do this only with a brand-new unit. If youâre using an old external hard drive, make sure youâve already saved everything on it somewhere else.
Formatting procedure.
1. in the Finder window, search for âDisk Utility.appâ.
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 âTransnd MACâ and unplugged everything else.
4. Click on âEraseâ â thatâs 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 âEraseâ (Bottom right)
Thatâs 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.

Satisfactory product, some false advertising.
For the price I was satisfied with what I got and the speed of delivery. However, the seller advertises the disk drive capacity as 4tb. I have ordered two and each only holds 3.63tb. If I’m paying for 4tb, shouldn’t I get 4tb?

Robust and reliable so far
Bought this for photo storage as I am replacing all of my WD passport drives, all of which have failed or started failing . Went for a “spinning drive” rather than an SDD as they are easier to recover files from if something goes pear shaped.
Well built, long enough cable and fast enough for photo storage. I may buy another one as a back up if amazon reduce the price a bit.

Best external hard drive
The best I ever had and the o my I buy. I have this since 2016 and had now issues. Iâm not scared if it breaks, if there is a liquid accident around it, if I just drop it in my pack pack, because it wonât get squashed. I bought a second one this year for my university stuff.
The only thing that happened over the year was the cable went loose so I had to replace it.

Great storage for my files.

Die Festplatte verwende ich als Absicherung meines umfangreichen Fotoarchivs. Es gibt nichts auszusetzen. Die Festplatte ist schnell und geräuschlos und macht einen stabilen Eindruck und ist für unterwegs / Outdoor gut geeignet. Würde ich wieder kaufen.

Tamaño correcto.
Sensación de calidad en el material y resistencia.
Pensaba que serÃa más rápido, pero tiene una velocidad adecuada.
Lo conseguà a un precio muy competitivo con el resto, siendo una buena marca.

I already have one of these HDD (4 years) and still going strong. I use it continually for time shifting and recording on my smart TV. I bought this second Transcend HDD because of its reliability, for file storage and to replace an inferior HDD which lasted less than 2 years.

Good design.
