    Automatic Windows 11 recognition and superb data transfer rate. Represents great value in comparison to more expensive more recognised brands.

    For a little extra money it would be good to have a carry case.

    In future update is would be great if the disc had USB type C connectio

    It was delivered on the date promised. Just plugged it in and it played immediately on my Mac. Despite the instructions that came with it, there was nothing else needed doing.

    Works very efficiently and at good speeds.

    Very happy with i

    Very easy to use, just connected and then found the device on my file manager. Was able to transfer a large number of files fairly quickly. The drive is very quiet and is responsive when I want to access the files. Overall very impressed with the quality and price.

    Bought this after finding my Xbox was constantly running out of space for large game files. I’ve not used an external hard drive with my Xbox before – but this has been great. You can download straight to the External drive and then copy across to the Xbox Series S for games that are X/S enhanced overwise regular Xbox One or 360 games run straight from the external drive. This external drive has made it really easy to save and play a range of games again. Highly recommended.

    Plugged in to the USB port on my new TV so that I can have a pause/record function on live TV. It was detected immediately, formatted accordingly then given a performance test to ensure it was up to the job, all done automatically with progress report onscreen and then immediately put to test which worked perfectly. There’s no LED to indicate anything at all is happening with the drive, and it’s completely silent so you can forget it’s there. Excellent value for money and no need for an SSD for a task like this.

    I have purchased many of these as I converted old vhs, camcorder tapes and dvds onto hard drives. It makes it easier to watch the films. It simply plugs into the tv with the 3.0 usb. Looks nice and modern and not too big. Nicely packed but would be great if they could include a case which is the only downside!

    Bought this for my new LG TV.
    It didn’t like my memory sticks when using the pause live TV function.
    Plugged this into the USB slot, formated it on the TV and bingo! can now record hours of TV and pause live TV. Which is the main function we wanted the TV for.

    Golden Review Award: 9 From Our UsersI was so happy with this when I initially bought it and it did last me a while, but then one day as I plugged it in i realised something was not right. the whole plug-in area had been rendered useless and came out of the hard drive itself, i was so upset I had had issues with it initially not being recognised but coped, for it to finally give out like this almost made me want to cry all my data and games are now gone from my laptop and I can no longer return or request a replacement.

    update: I actually contacted the sellers after my discovery and they repsonded so fast and offered me a replacement immeadiately, im so grateful and lucky honestly I advise you buy at your own risk

    4.0 out of 5 stars generally not worth it tbh re: UPDATE!

    Golden Review Award: 3 From Our UsersOnly had this for a few days. It is a plug and go – very easy to use. Incredibly light device too. As others have said, you don’t get the full memory as advertised due to whatever software is already in there for it to run. I.e. 500gb is about 463gb in reality.

    Plugs in, takes the data, quite small, not too large and not so small as to get lost easily in the workplace and a label on it can take more information.

    straight out of the box, plugged in and it was ready to go. data transfer was very fast and it seems reliable. Great product, I’ve had let downs from other external drives in the past. I think I’ll probably buy a few more of these ones though. (I’m using Ubuntu Linux, not windows)

    This is good for recording off lg tvs but before you set it up to your LG tv plug it into a laptop and reformat it into NTFS has it won’t work in FAT32 format,then you can only record 1 program at a time but can schedule different recordings at different times.

    Currently recording a lot of gameplay and silly daughter didn’t realise it would fill up the laptop storage so fast . Went with the 2tb for extra room. So far very happy with it. Easy to use and transfers files super fast ( these files are 90gb and normal SD cards would struggle with this, well for us it is)
    The lead isn’t too long which is nice, it has a light which indicates when it’s on.
    So far so good.

    Golden Review Award: 3 From Our UsersCOD have such storage eating games, but I absolutely love them. Was so glad I got to be able to install all my favourite games and still have COD! It’s pretty small too, not an eyesore and it works wonderfully

    he color is a lovely personalization and i majorly prefer it to the office like vibe that comes with most black ones. connects by usb cable that comes with product, and there is a red light underneath the cover that turns on when connected. The wire is very sturdy so doesn’t easily become disconnected, I’ve had absolutely no issues lifting my laptop up with the hard drive dangling or staying connected while in my bag, which is a massive pro compared to USB sticks that can be easily bent.

    Golden Review Award: 10 From Our UsersI recently invested in the 500TB SSD for my Xbox, and it’s nothing short of revolutionary! The colossal storage capacity has liberated me from the constant battle of deleting games to make space. Installation was a breeze, and the lightning-fast loading times have transformed my gaming experience.

    This SSD is a game-changer, quite literally. With room for a seemingly infinite number of games, I can now curate my virtual library without compromises. While the price might raise eyebrows, the convenience and future-proofing it provides make it an investment well worth considering. Say goodbye to storage woes — this 500TB SSD is the epitome of digital freedom!

    Golden Review Award: 6 From Our UsersI was a little bit disappointed that the outer casing was made of plastic. I just assumed it would at least have a metal casing, given that it looks like metal in the pics. Other than that it seems to work well enough and is easy to use. It also transfers files quite fast. Overall I would say it’s good value for money.

    I recently purchased this portable hard disk, and I’m delighted with its performance. It’s of excellent quality, operates quietly, and its portability is a big plus. Highly recommended for anyone seeking reliable external storage!

    I originally meant this for a gift, but I ended up using it for myself and I must say I am extremely happy with it.

    The price itself beats most similar products on the market, which is a happy coincidence as I am still studying.

    The design is perfect as it fits anywhere and is very resistant to shocks or moving around.

    I was most surprised at how fast the device is, as I was able to download entire feature films on it.

    My favourite thing about it is probably how reliable it is. Although I am very careful with my IT stuff, I have had a couple incidents of my laptop running out of battery whilst the drive was plugged in, and every time I plugged it back in, all my files were safe and sound.

    For now, the size on it is perfectly fine for my use of it (500MB), but I would not hesitate to get a new drive with larger capacity from the same seller. Thanks so much !

    Bought for son’s PS4 that was short on memory as he gets into larger capacity games. Worked straight out of the box and has been running for a few weeks. It must be working good as I have not heard a word from my son about storage issues since we installed it.

    Great small compact 500gb external hard drive. Works great on my Xbox One S 1tb Console it gives me more game space to transfer your games straight from the internal hard drive to the external hard drive which is very simple to do. Good value for money I guess time will tell if it still works okay. That’s why I gave the product 4 stars only.
