4TB Expansion Desktop Hard Drive | USB 3.0 (STKP4000400) | Desktop HDD for easy backup, plug-and-play, drag-and-drop, auto detects Windows & Mac. 2-Year Warranty + 2-Year Rescue

After reading a lot of reviews that said it's noisy and slow I initially tried to cancel my order but missed the cancellation point, anyway I decided to keep it as it was a Prime day special offer, I haven't suffered any of the woes I read about in negative reviews and so far it works without fault it is actually very quiet in comparison with many other USB external drives I have used some of which I still own, to the speed I'm getting about 160MB/s transfer speed over USB 3.0 which I think is quite reasonable for an 8TB 3.5" 54 RPM HDD, I bought it to backup my film & TV series from existing HDD drives just in case one of them fails and I'm really glad I bought it when I did as I only paid £168.99 it's now selling for £240.65 so a saving of £71.66. Cost aside it's really useful backup solution and has a small footprint my only criticism is it doesn't have an on/off power switch so you'll have to unplug it

Works great and is very easy to set up. Quite noisy and you can feel the ticks within my desk. You have to use the enclosed PSU (not a generic 12v HDD PSU) because it uses a lot more power than other HDD's, but of course, 26TB means you can give away all those old units! The PSU comes with a variety of pin adaptors for every plug on the planet, including EU, UK, Oz and US. I have purchased this purely to backup my main file server and store it off site. To initially copy 21TB took about 30 hours and once initially copied, the weekly update takes about 15 mins, so quite nifty and perfect for my application. I personally, would not use this as a permanently connected drive, its a bit too big, noisy and clunky (and of course 26TB is way beyond a USB connection!), a built in drive is better for speed, power, ventilation, vibration proofing etc. and this drive is probably the ultimate for being able to transport that data in a safe secure manner. You will need something with lots of memory to connect to it because chances are that 26TB of data will probably be over a million files! Make sure windows is set to 'Not indexed' and your anti virus scanner is configured to 'not check' when connected because something this large in capacity takes hours not minutes (and my PC is 5.6 Ghz, 32G RAM so no slouch!)

This hard drive bucks the trend of computer memory devices beconing cheaper per MB in recent times. It id an ezpensive option for most, and is not terrifically speedy transferring data to and fro. For those out there with sizeable video libraries, this device is nonetheless the best optoon for your storage needs. Seems to be robust enough to safely keep your data safe, and drlivers data at a decent rate. Knock some cash off and the 4 stara would become 5 easily.

Firstly, the HDD cleared customs in approx. 8 hours, and arrived a day early, happily. It reads/writes at approx 40MB/s MAX, averaging around 35 to transfer a lengthy media file, in the 8TB Version, which has 7.27 TB of usable file space on it. Its not too big, the plastic case had a film on it, and the wires are adequate to sit at the PC or TV. It was plug and play with no need to format or worry about getting the HDD recognized by the system. It is easy to carry and move and would fit in most carry cases. Its jet black and moderately shiny and has an LED built in above the power port on top to show its active. I'm confident this drive should last me 10 years or more and will be a fantastic addition to my digital library. I played a UHD 4K video and it operated at a peak of 10%, mostly negligible usage. Although its not the fastest HDD you can get, I consider this very good value for money and a high quality product. You can plug this in your TV and play videos or music easily enough since its not USB powered which is a nice bonus.

This is now my 6th High storage hard drive from Seagate. I have had them when they first started with the 8TB then the 12TB, 14TB and again with the 16TB so this 20TB or 18.1TB after format, was the way to go because my 14TB drive has all my videos on and they need a backup. I know a lot of reviews say this does about 120-135MBs (note) I have learnt that if you are transfering a lot of data, point a standard home fan on hard drive to keep it cool and it will transfer at it's fullest for me that is 210-235MBs. I have just moved 1TB in hour and a half and am in the process of moving 8TB of video and it is hovering between 215 and 235MBs with the fan pointed at it and it is saying it should take about 11 and a half hours. Which sounds bad but is very fast. See Screen Shots! (this will change if any of the drives start to over heat) yes i could use a NAS but I started with these and it would cost a lot more to change now. So if you need high storage for videos or photos like RAW photos, these drives have lasted me years, i have some 2TB ones that are over 10 years old now. Also, it comes with different electrical connectors for if you go on holidays. Nice to have the option. Very sturdy build, easy to setup, i usually register them, then reformat to NTFS, sometimes you'll get a free photoshop package for a set period of time.

I ordered this item (the 6GB version) on the 3rd of July 2025 in order to move a large number of files I did not have room for on my laptop, and which were causing it to slow down, but that I wanted to keep. Today is the 3rd of September, just two months later, and I have switched on my laptop to find it not only frozen, but when I did finally get into it, various changes I did not make myself to my laptop, and this hard drive beeping and disappeared from my laptop, along with all of the files stored on it. So this hard drive is about as much use as a chocolate donkey, as far as keeping your files safe, and storing them externally. It also apparently makes changes to your devices, without your consent, and without your knowledge. I had various items and files stored on my desktop, including a screensaver, which have also completely disappeared, which were in no way connected to this hard drive, and were stored on my laptop itself. There is zero reason for any of this to happen. The hard drive has just been sitting on my desk the entire time, and there were zero error messages and nothing has changed. It just suddenly started beeping today, and on switching on my laptop I found it frozen and the desktop altered and files missing. There are no help screens, error messages and no way to access it to actually find out what has occurred either, so super helpful. I have already got my money back, but that's not really the point is it, the point is that I have lost all of my files, as have others, and that this product cannot be trusted for its one job. Literally its one job, and not even over the ridiculously short period of two months, and it's not as though this product is cheap either. If you cannot trust it, then it defeats the object of having it. If you're looking for a completely useless piece of black plastic, that wastes your time, energy and money, loses your files, makes changes to your laptop/computer without your knowledge or permission and costs you more than it is worth, I highly recommend this piece of rubbish. Update: this hard drive was sent back to Seagate, as per their "Data Rescue Services" guarantee, and despite absolutely nothing happening to it, and it just completely failing from merely sitting on my desk for a few months, weeks later they wrote to me to say nothing could be done to save any of my data so they would be scrapping it. They then sent me a replacement hard drive, which then failed before I had even had time to move files onto it. Not that I either had any files left, or felt inclined to do so anyway. During the time the first hard drive failed, I also had an issue with my broadband and had no broadband for months, so this hard drive was meant to be a back up for the fact that I was unable to save documents to the cloud. With both failing simultaneously, I lost all of my files. I'm still infuriated daily by discovering files I've lost that were moved to this hard drive during this period, and today was yet another day I went to find some files and discovered they were a whole bunch and weeks of work that were lost to this hard drive. So I came to update this review to advise you, in case you were wondering, that not only is this hard drive utterly useless, the "Data Rescue Service" is completely worthless too.

A solid HDD drive with a massive storage space. I've been buying Seagate HDD's for a long time and they have never failed me. I trust the brand and this purchase was no different. Easy to use, just plug and play and the drive is pre-formatted in NTFS. The write speeds are solid at 100-150 MB / Second and the read speeds are quite good too. Have a number of 4K resolution videos and ton's of photos which I have stored on the drive and experienced no lag in reading them from the drive.

I was in desperate need of a back up solution for my photos and videos to free up space on my NAS. The solution did not need to be "always on demand" but rather a manual back up device that I could plug in once a month. The transfer speed were absolutely acceptable and what peace of mind to now have an empty NAS ready for our next travel adventure to upload photos and videos to knowing all of our historic memories are saved on this drive. Fully compatible with our Apple ecosystem. No messing around with installation set up apart from ensuring the file formats were correct. USB - C connectivity ensured fast data transfer. Sits nicely under tour monitor so it is not in the way.

Achei o produto excelente pois formatou em NTFS (veio formatado como exFAT); como uso para fazer backup de muitos arquivos pesados precisou ser no formato NTFS que é compatível com o PC. Estou fazendo o backup plugando o HD através da USB 2.0, apesar de ter percebido que no USB 3.0 é muito mais rápido, porém para não dar problema de salvar os arquivos, prefiro fazer de forma mais lenta. O produto chegou muito rápido que esperava, adiantando em 5 dias úteis para receber. Até agora não deu nenhum erro das trilhas do HD e a capacidade dele me satisfez. Mais para frente quero comprar outro igual.

Don't be fooled .. saving your info to the 'cloud' .. is just sharing to someone else's computer. Save everything on your own devices and share not with who knows who's out in the aether. Privacy is privacy and this is how you do it.

Great service and so far a perfectly extra storage backup hard drive....it is perfect for all my photos. The seller was amazing.......my item arrivede earlier than expected..it I would order again!

Bom
