Transcend 4TB StoreJet 25M3S USB 3.1 Portable Hard Drive Rugged, Anti-Shock Resistant, Compact and Lightweight with Lightning-Fast Speeds and a One Touch Backup Button (Iron Grey) TS4TSJ25M3S

Great product!Traveling dada fast and the power connecting stability. Highly recommended.

1 year on, going strong. Good for storage and retrieval.

No worries with this. Really easy set up no problem running or access to it.

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.

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.

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.

Very good would recommend.

Had a couple of these hard drives before but 1TB size and very happy. This 2TB is ok but if I had one complaint it would be that it doesn't seem to like a large data transfer all in one go for some reason. I have used it to back up a powered 2TB drive that is attached to my desktop computer with all of my movies on. Try to copy over a large folder say 100-150 GB and it would stall and freeze, but break it down to smaller chunks and it worked fine. So still 5 stars, but with a raised eyebrow.
