Quiet, fast, user friendly
Typical size for a desk top external drive with good looking case. The profile of the case seems to imply that it can be used in a vertical orientation, i.e. standing on it's long narrow side, as with a lot of other drives, as it has slightly protuberant feet allowing ventilation, but it is unstable in this orientation and falls over regularly unless you can arrange additional support. In this orientation the beacon light is on top. If it is used flat one may not be able to see the beacon. This may well not matter to you. A generous length of cable is provided from the plug-in power supply with a large (ish) connector, handy for sauage fingers or stifff hands. Downside is that as always the cable is not as flexible as it could be and over time will probably be prone to cracking at bends, especially at exit of connector. The USB cable is a good length, good quality with used friendly connectors. On the positive side the data transfer and saving seems to be genuinely quick (subjective opinion, not measured). Not saying that other makes gild the lilly in this area, but not with this unit. It is silent in operation and is the fastest to connect at power-up of hte various drives I have. Overall nitpicking niggles do not outweigh the positves. Very happy purchaser.

You Can Never Have Enough Storage!
An early Christmas present of a PS4 Pro console for the family saw me looking to buy another external HDD. Have already bought the same Seagate 6TB external HDD earlier this year when my son's X-Box One became full, and had no hesitation in coming back to buy another one. I even got a better deal as while I paid around £110 for the last one, this time I found one in the Amazon Warehouse for £85 simply because the packaging was damaged. Now while HDDs can fail, the simple fact is any brand of disc will give up over time, and some will be faulty straight out of the box. Nothing in life is perfect or lasts forever, but Seagate has been one of my go-to brands for many years. I have rarely had issues with any discs, whether internal or external, and price versus quality and storage means they sit comfortably within my budget. While they are only a single disc unit, given they are being used to store games that I can reload if anything should go wrong, I deem the need to backup them up as unnecessary. Unlike the rest of my computers where everything is backed-up in triplicate. While I could go into all the technical aspects I'm gonna leave this review simple and state the HDD runs pretty fast when connected using the 3.0 USB, and noise wise is almost silent when operational. The only modification I have done to either HDD is add slightly deeper felt strips on the base. (A pack of which cost me £1 and I still have loads left.) This helps to absorb any vibrations, and raises the HDDs higher off my units to allow for a better airflow to aid cooling.

it's a good size for an Xbox
Ideal for the Xbox especially at this size and price point. I bought this for the Xbox one X but first transferred all the data from my one S, over 2.5TB of it. While the read and write speeds are nothing spectacular this drive is a good work horse and ideal for gaming. It's 6TB and in this day and age where games can be 100GB in size there seems to be no point in buying a smaller drive, any games you own are always available anyway, you only download a game to play it. When you get to the point that you've got 500 games including game pass games then you need the space this drive provides. I ran this drive for 24 hours non stop and had no problems with noise or overheating and to set it up on Xbox was easy, plug in, format to Xbox and play.. Edit 30/05. I have noticed that the drive makes noises at random times that can be annoying, the noises are always the same so are a design thing and not a random problem. If you're using this for Xbox and have your Xbox set to install remotely then you may find this noise annoying as you have to leave the drive on all the time. I switch my drive off when it's not in use now..

Seems fine - speed test results in review
(Update 31/1) - read a few reviews about failures after a few months so thought I'd post an update. Mine is attached to a NAS which is backed up to it daily. So it's in regular but not heavy use. It is located on a desk with space around it for cooling (has not got hot in use that I can tell). NAS not able to read SMART status from it for some reason. No problems yet (but only 3 months). Will update if this changes. Mine did come with a UK plug, but it sounds like recent orders have not. I'll end this update with a small rant. Frustrating to do a review putting in a bit more effort (e.g. performance testing it) and then have someone mark it as unhelpful. There's any number of other reviews which just say "excellent drive" or similar. If you want to mark this as unhelpful, fine but please leave a comment saying why. By marking as unhelpful it just means that reviews with less substance get shown first which is of no use to anyone. ********** Initial thoughts after unboxing and setup (benchmark attached). Will update after use. Plugged into a Windows 10 PC and it auto installed drivers. Drive reports as 3.63TB capacity with 5.91GB used. Files visible are 18MB. There's a registration app, it seems to just open a browser window with registration fields but there's no explanation. HDTune benchmark reports 60.5 MB/s minimum, 176MB/s maximum, (average 166MB/s) 124.3 MB/s burst rate. Physical appearance is neat enough with some venting present in the case and a blue activity light. Power adapter is integrated into plug rather than being a trailing block. It comes with continental and UK plug adapters.

Huge space and slow speed make this an ideal backup solution
I grew up with floppy disks, so a 4TB hard drive is kind of mental. Hard to say much about it, I’ve had it a few months now and it’s worked perfectly reliably. But, take this from a seasoned technician: absolutely every hard drive fails eventually. So never store anything you wouldn’t want to lose on just one drive. That’s why this is my backup drive, and it has more than enough space for my two Macs, one PC, a 2TB music library and probably 1tb of other media like films, games and photos. It’s not super fast, but magnetic spinning hard drives (I.e non-SSD) aren’t fast. But a great backup disk. I wouldn’t recommend running an operating system from a USB external hard drive, in case you’re considering it. You’d be much better off spending the same money on the biggest SSD you can afford. It will make the difference between a PC that feels like it’s from 1999, and one that is from 2021. I’m not kidding, SSDs are that much faster.

Boringly reliable & very unexciting :)
Bought a 5Tb one of these for my Xbox One S & found it so quiet & easy to setup that I bought a 2Tb version for my Xbox 360... And then another 5Tb one for my daughter's Xbox One. And I'm about to buy myself a 4Tb one (only because the 5Tb is out of stock) for storing some photos on while I'm away from home (I'm a photographer & will need to download & edit photos while I'm away) - once I'm back, I'll wipe the drive & hook it up to my Xbox One S (yes, the 5Tb drive is already full!). Basically this is a highly unexciting drive that does a highly unexciting job in a boringly reliable way - to the extent where I'm more than happy to spend my own hard earned money on repeat purchases (when it comes to storage - either external or internal - boring and unexciting is definitely key. I want a drive that will do the job with no fuss or hassle, and that's exactly what these do). If that doesn't tell you that the device is worth buying, then I don't know what will!

EXCELLENT VALUE AND FLAWLESS COMMUNICATION WITH OS X EL CAPITAN AND TIME MACHINE!
I purchased the 4TB Seagate Expansion Drive. As an iMac user, I was initially concerned that this disc would not support OS X El Capitan. However, I need not have been concerned. This runs perfectly with iMac and my current software OS X El Capitan Version 10.11.3 and perfectly supports Time Machine backups. Although it did not work straight away, from initial plug-in, it only took 2 minutes to go into Disk Utilities and erase the drive to allow Apple to automatically re-format it. I am not tech-savvy, so it was a relief that this was so quick and easy. I found that this drive was considerably cheaper than other backup drives that I had looked at, so that also made me a little concerned. Again, I shouldn't have worried. It's a great little device, very fast to backup, very quiet, and sits at the rear of my 27-inch iMac computer nicely, without looking unsightly. In summary, I would recommend the Seagate Expansion device to anyone looking for extra storage or a backup option.

A cheap way of expanding storage
I review products on my blog and needed something to expand into temporarily.... Ok let's keep the introduction simple....This is an excellent way of increasing your storage capabilities or setting up a key part of the 3-2-1 back up rule and if you're a data hoarder like me you will fear the data loss issues and so want something to solve your storage issues. So why not just upgrade your hard drive in your computer? To be honest it's not a bad suggestion but when it's going to cost anywhere from £79 for a relatively unknown Intaiell 1TB internal SSD to an eye watering £709 for a Samsung Evo 4TB internal SSD on Amazon - if you can upgrade it yourself then go for it but for the most part, those prices are plus installation. This drive works out at £16.99/TB.... As this is a desktop expansion drive, it is not built to be portable - if you want portability you should be looking as a USB powered SSD because these 3.5" HDD have moving parts and also a power cable. It also weighs 948g meaning it is weighty enough to be stable on desks and tables. Within 30 seconds I got a small notification to say the driver was installed and we were good to go; you don't have to but I always reformat it again just to make sure and a minute later I was ready. So I started dragging and dropping all the documents, images and movies across and the USB 3.0 managed just fine - I think I had around a terabyte of data and it managed just fine and took around 20 minutes to complete. That was it - quick as that. Once my NAS was set up and running I was then able to reformat it again, and am now using it to store my Xbox One games and saved game data on meaning its usability has continued and will hopefully continue to work for years to come.

Llegó en tiempo y en buen estado
El disco llegó en buenas condiciones y en tiempo. En mi experiencia, estos discos son buenos, tengo varios y me han funcionado muy bien. Este en específico tiene el problema del ruido que hace, es algo llamativo, pero en cuanto a funcionamiento ha salido muy bueno.

Excellent disque dur externe
Ce disque dur va bien au-delà de mes espérances. Je ne comptais utiliser que son espace de stockage, passant par USB3, je ne m'attendais pas à un tel niveau de performances. Mes premières copies sur ce disque dur dépassant 150Mo/s et mettant au taquet mes autres disques durs internes (pourtant dans les gammes "performances" des autres constructeurs), j'ai décidé de passer un petit banc d'essais pour mesurer ses performances, et quelle surprise ! Bien évidemment, je ne peux pas comparer ce disque dur externe à mes SSD, et encore moins au SSD NVMe qui arrive à un taux de copie de plus de 3.6Go/s, mais je joins en pièce jointe (photo) les performances mesurées sur 3 de mes disques HDD (les deux autres sont internes, branchés via SATA) pour vous rendre compte des performances plutôt exceptionnelles pour un disque dur externe (HDD). Je signalerais tout de même un point plutôt négatif, à savoir la qualité du plastique utilisé en guise de coque, bien que très joli ne donne pas un sentiment de grande solidité. Ce HDD pèse son poid, ce n'est cependant pas vraiment un point négatif, celui-ci étant branché en permanence à mon PC et reste posé sur sa tranche (Avec des petits patins anti-dérappant, au poil). Je suis pleinement satisfait de cet achat, d'autant plus que je l'ai acheté pendant les French Days (Début Juin) à un prix écrasant toute concurrence. Je recommande ce produit, y compris au prix habituellement affiché, il les vaut bien.
