Seagate 4TB Expansion Desktop Hard Drive | USB 3.0 (STKP4000400)

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!)

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

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.

Plenty of storage but a bit slow to respond. Doesn't take up to much desk real estate but I had to put it on a shelf to prevent it from adding to the hum. Not as solidly made as my old 2TB Seagate, let's hope it's as durable.

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.

Ordered late in the evening of Tuesday 6th Jan & delivered during the afternoon of Saturday 10th Jan. It seem physically robust as do its PSU, cables & connectors. Its LED read-write indicator works correctly. Nominally 28TB, it formats to 25TB in Windows [diagram enclosed]. It's on my desk and I can hear it ticking as it writes/reads. It took a day to write 12-13TB to it from my older, smaller external HDDs [which are now its backup drives, I use a RoboCopy batch script]. Its average write speed was about 100-150MB/sec. The included PSU output is 12V 1.5A - hence 18W [diagram enclosed]. I opted for the 4 year extended warranty for £10. Its terms include a pre-paid return should that prove necessary [which is better than Samsung-Seagate offer in their warranty]. - I have nine other Samsung-Seagate external HDDs, aged up to twenty years, and none of them have ever malfunctioned. Whilst writing this review, I've dug out & re-checked two twenty year old ones to make sure they still worked. - I started backing up my data as soon as I'd copied my files to it. Data recovery services may not succeed; they are not a substitute for backups.

Working as it should

Disque dur fiable et très spacieux. Attention toutefois : certaines multiprises ne sont pas assez puissante, ce qui peut empêcher le disque de fonctionner correctement. Sinon, rapide et silencieux. Parfait pour stocker beaucoup de données.

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

External HDD that is fast in data transfer, large in capacity and value for money. Got it during lightning deal, which makes it every more worthwhile!

Ho acquistato questo HDD esterno Seagate Expansion da 10TB per fare il backup di vari dischi da 1TB che utilizzo in studio, come fotografo. Devo dire che è stato uno dei migliori investimenti che abbia mai fatto, soprattutto come professionista che lavora con file davvero grandi. Gestisco un flusso costante di immagini RAW da mirrorless (40megapixel per file), oltre a video per progetti documentari. Con 10TB di spazio, questo disco mi ha permesso di fare il backup di 4 dischi da 2TB, centralizzando una parte del mio archivio in un unico disco, e lasciando ancora 2 TB di spazio libero per il futuro. 𝗖𝗮𝗽𝗮𝗰𝗶𝘁à 𝗲 𝗽𝗿𝗲𝘀𝘁𝗮𝘇𝗶𝗼𝗻𝗶: 𝘂𝗻 𝗺𝗼𝘀𝘁𝗿𝗼 𝗱𝗶 𝘀𝗽𝗮𝘇𝗶𝗼 𝘀𝗲𝗻𝘇𝗮 𝗶𝗻𝘁𝗼𝗽𝗽𝗶 Partiamo dai numeri: 10TB netti, che equivalgono a circa 2,5 milioni di foto RAW da 40MB ciascuna o migliaia di ore di video 4K non compresso. La velocità di trasferimento è solida per un HDD meccanico: legge/scrive a circa 180-200 MB/s via USB 3.0, collegandolo al mio MacBook Pro o al Mac Mini. Non è un SSD velocissimo, ma per backup e archiviazione è perfetto: ho trasferito 2TB di archivio fotografico in circa un'ora senza surriscaldamenti. È plug-and-play, si formatta in un attimo in APFS on in EXFAT e il software Seagate Toolkit incluso permette backup automatici programmabili – ideale per chi come me scatta sul campo e scarica tutto a fine shooting sera. 𝗖𝗮𝘀𝗶 𝗱’𝘂𝘀𝗼 𝗰𝗼𝗻𝗰𝗿𝗲𝘁𝗶 𝗽𝗲𝗿 𝗳𝗼𝘁𝗼𝗴𝗿𝗮𝗳𝗶: 𝗶𝗹 𝗺𝗶𝗼 𝘄𝗼𝗿𝗸𝗳𝗹𝗼𝘄 𝗾𝘂𝗼𝘁𝗶𝗱𝗶𝗮𝗻𝗼 Come fotografo freelance, lo uso in tre modi principali che mi hanno cambiato la vita: 1. Archivio a lungo termine: Ho migrato tutta la mia libreria Lightroom Classic (oltre 50.000 immagini dal 2018) qui dentro. 2. Condivisione e editing collaborativo: Lo porto in studio per condividere file con assistenti o stampatori. Per un progetto recente di ritratti aziendali, ho caricato 2TB di PSD e il disco ha retto sessioni di editing Lightroom/Photoshop per 8 ore filate senza un minimo lag o crash. È come un “cloud personale” fisico, ma più veloce e sicuro di Dropbox o Google Drive, soprattutto per file grossi. 𝗦𝗼𝗹𝗶𝗱𝗶𝘁à 𝗲𝘀𝘁𝗿𝗲𝗺𝗮 𝗲 𝗰𝗼𝗻𝘃𝗲𝗻𝗶𝗲𝗻𝘇𝗮 𝗶𝗺𝗯𝗮𝘁𝘁𝗶𝗯𝗶𝗹𝗲 Il disco è solido, compatto e molto silenzioso (rumore di fondo impercettibile) e non si scalda eccessivamente nemmeno dopo ore di uso intensivo. A circa 20€ per TB, è estremamente conveniente rispetto ai concorrenti. 𝗕𝗼𝗻𝘂𝘀 𝗦𝗲𝗮𝗴𝗮𝘁𝗲 𝗺𝗼𝗹𝘁𝗼 𝗶𝗻𝘁𝗲𝗿𝗲𝘀𝘀𝗮𝗻𝘁𝗶 Il disco Include 1 mese GRATIS di Adobe Creative Cloud Pro (tutte le app), risparmiando 60€ e integrando perfettamente il mio workflow. Più il servizio Rescue per recupero dati, che vale da solo centinaia di euro se mai ne avrete bisogno. 𝗣𝗶𝗰𝗰𝗼𝗹𝗶 𝗰𝗼𝗻𝘁𝗿𝗼 Non è portatile come un SSD (pesa 2,5kg e richiede alimentazione esterna), e per editing video 8K super-intensivo meglio un NVMe interno. Ma per il prezzo e lo scopo, è davvero ottimo. 𝗖𝗼𝗻𝗰𝗹𝘂𝘀𝗶𝗼𝗻𝗲: 𝗹𝗼 𝗰𝗼𝗻𝘀𝗶𝗴𝗹𝗶𝗼 𝗮𝗹 𝟭𝟬𝟬% Se sei un fotografo, videomaker o chiunque con molti dati da archiviare, prendi questo Seagate Expansion 10TB senza esitare. È solido come la roccia, conveniente da urlo, e quei bonus Creative Cloud + Rescue lo rendono un affare irripetibile. Davvero consigliatissimo se sei anche solo una persona che ama scattare foto con il telefono e vuole avere un disco a casa dove scaricare dati e foto di famiglia. Molto conveniente, scarichi tutto qui e non ci pensi più!
