UnionSine 6TB 3.5" Desktop External Hard Drive USB3.2Gen2 Type-C HDD Storage Compatible for PC,TV, Desktop, Laptop(Black) HD3510

Just picked up this UnionSine 10TB beast, and let me tell you—exactly what I needed to dump my ever-growing collection of 4K movies, games, and whatever random stuff I can’t bring myself to delete.What’s good: 10TB is a lot, man. I mean, “never have to delete anything again” levels. If you got a hoarder’s heart, you’re gonna love it. In terms of speed, it was decent. Sure, it is not an SSD, but it’s fast enough to transfer big files without making me want to gouge my eyes out. Read speed hits around 160MB/s, and write’s about 110MB/s. Not too shabby for a mechanical drive. It is compatible with pretty much anything: PC, Mac, Xbox, PS4—even smart TVs. Nice to have that flexibility.They also upgraded the quality of the cable, so it feels tougher than usual. Moreover, it contains anti-vibration stuff inside to keep the noise and heat down, which is a plus.What is not that great? It is not an SSD. If you want insane speeds, this is not it. It’s a good hard drive, but it will not teleport your files anywhere. Also, unlike the smaller drives, this one needs its own power supply, so it isn’t as portable as I hoped. Not a dealbreaker, but just so you know. The verdict: If you want just utterly ridiculous amounts of storage and don’t mind the somewhat slower speeds of a regular hard drive, this thing is actually a pretty great buy. Perfect for backing up your life, your games, your movies, and everything in between. Just don’t expect SSD speed, and you’ll be happy.

Wow what a lot of TB for your money. I have backed up 3 laptop systems & files. I have also backed up 5 external drives. I now have this as a go to should anything crash.

Easy to setup - Plug it in and away you go.Value for money - Cheapest i could find.Lightweight - about the weight i would expect for a 3.5" drive in a caddy...Missing features -Reliability - 0/ZERO starsCustomer Support - 4 stars - they provided a replacement USB HDD without extra cost involved. Not interested in helping getting data off faulty HDD.Build quality - 2 stars I looks good and looks like it would last but obviously the looks are skin deep only. Under the shiny plastic and nice vents / graphics, is a cheap drive. Which is what you paid for...My history with these drives -Some month ago now my NAS had filled up and it was begging me t o replace a disk due to "issues" So brought this as a backup (Just in case if failed on me before my new NAS arrived, which was on back order) and backed up 10TB of data on it, so that i could migrate from my old to my new NAS. Copied across not a problem (after a few days of continual copying on 100Mb/s network connection... OLD NAS) Anyway likely i did, as old NAS then starting making clunking noises and showing up bad bit rot and drive errors on 2 of the 4 NAS disks and promptly stopped working. Thought, wow how lucky am I... New NAS arrived a week later which was 2 month faster than expected. Plugged in the new NAS and configured it. All fine until i started to copy data off this drive onto new NAS. Started off ok and left to do its stuff over night via a USBC/3 cable rather than over network cable, as thought it would be faster. Woke up the next morning to find only 4% complete and not moving, this drive and NAS was silent. No chatter like there was when i left it copying. Looked at the NAS and it reported IO Error. Checked HDD and couldn't access it. Rebooted this USB HDD and the dreaded clunk, clunk, clunk, buzzz, buzz, spin up/ spin down/ spin up... you get the idea. Drive had failed. Unable to get any more data off it and so tried in vain to recover the old NAS stored Data, to see if i could get that to work with new NAS and again was unsuccessful.Contacted seller and they apologised and supplied new HDD free of charge (which was very nice of them). I did explain this doesn't help me as i have 15 years of family photos and videos on this device along with 20 years of legal/ private emails / files on it. Company not even entertain me regarding recovering it.So now going to have to save up / fork out £400+ for a data recovery company to recover the data from failed USB HDD onto the replacement HDD supplied by company (which i hope does not fail during the process or when i move back onto NAS when recovered) before making a backup on the cloud like i should have done in the first place, rather than paying out for this.Moral of this story, HDD fail even brand new ones, NAS's fail over time (specially when you fill them up all the way!). When you think you have a copy, take another copy in a cloud if possible. Suppliers don't care if there HDD goes down with your data on. Its your fault for not taking a backup, even if this was a backup... If i had done the 3 copies i would be £xxx better off by now! When i finally get data recovered will have family photos in 3 places - one of which will be in cloud. Just in case one dies/ gets hacked/ or gets corrupt/ destroyed.

Good vakue, I use onkly as backuop disc for my 8Tb laptop. The one staer drop is because it is a bit noisy.

So it's not as small as some other external drives I've seen, norc is it the fastest I've used. However it does represent very good value for the capacity. It comes formatted as exFat which is good if using across multiple operating systems (for example a backup for your phone and computer), after formatting you end up with just over 9Tb of storage which was more than enough for me to backup my two laptops, three tablets, phone and as a backup for my games SD card I use in my retro handheld. Overall a decent solid build, would have liked to see a USB power lead rather than a barrel plug but for the price paid and the large storage capacity it's a solid purchase I'd recommend.
