    I recently purchased the Seagate BarraCuda Internal Hard Drive HDD and I must say that I am impressed with its performance. The hard drive is easy to install and offers excellent value for money. I have been using this HDD without any bad sectors, and it works perfectly.
    This Drive is designed to provide reliable and fast performance for your PC, whether you use it for gaming, music, video, photo editing, or any other computing task. It also features Seagate’s Multi-Tier Caching Technology, which optimizes data flow and enhances read and write speeds.
    It uses the latest 6Gb/s interface and runs at 5400 RPM. It has a cache size of 256 MB and a data transfer rate of up to 190 MB/s. The product comes in various capacities, from 1 TB to 8 TB, depending on your storage needs and budget.

    Golden Review Award: 11 From Our UsersGreat Hard Disk Drive (HDD), arrived quickly, and tests fine BUT it was delivered packaged in a paper bag-type envelope, inside was a cardboard sleeve and directly inside that was an antistatic bag containing the hard drive. (See pic of actual packaging). No bubble wrap, no clamshell box, nor any protection of any kind surrounded the component; not even a label on outer envelope stating ‘fragile’. A single drop, or hard knock in transit could have destroyed the delicate drive from working at all, not satisfactory packaging at all for an electromechanical device such as a HDD. Otherwise delighted with purchase and would buy again, simply hope this feedback gets to the shipping/packaging department to save any future frustrating and/or costly issues for future customers.

    4.0 out of 5 stars Good drive BUT Amazon please note ...

    Golden Review Award: 3 From Our UsersThis is a very good, high capacity hard drive with a decent sized buffer built in so that exceeds the performance of many 7,200 rpm hard drives. As such, this is the second one I’ve purchased.

    Data txfer rates are good both read/write. Easily streams multiple files / feeds. Was worried about speed as its 5400rpm but little or no difference over a 7200rpm model ; also a lot quieter.

    Golden Review Award: 2 From Our Usershis product is exactly what you pay for

    it provides a decently large amount of storage for anything you might need the storage for eg gaming graphics, game development and so much more

    the overall speed of the hard drive isnt bad but isnt the best but to be fair that is exactly what you should be expecting with a hard drive in general but for the speed its rated at it does an exceptional job

    so overall id give it 4 stars and say its 100 percent worth it if you need some more storage and arent willing to shell out on an ssd

    I’m using this in my NAS server. Had no problems with speed or stability. If using it in a PC it would work fine for game storage but please get an SSD for your operating system. It’ll be the best purchase you ever make.

    When I bought it I thought that because it was very large it would take long to open things but nothing wrong has happened and I would recommend it if you play a lot of games on your pc

    Well packed, new drive, Windows recognised the drive instantly and no issues reported. Read and write speeds are okay.

    Working as expected

    A nice basic drive that seems to be more then quick enough as the second drive in my HP laptop. Quiet and doesn’t get hot.

    Been using for a few weeks without issue, but will update if found to be unreliable.

    Very fast and efficient was slightly finicky to install in my pc but believe that was an issue on my end

    Item received quickly but was delivered rattling around in a box far too big. Also did not come in manufactures packing just loose in a tatty cardboard box.

    As in the title, the HDD is an absolute tank for storage. 2TB at this price is immense and I have gotten good usage out of it. Just don’t store your OS on it, as it tends to lag behind quite drastically. I’d suggest pairing this with a Samsung SSD and keeping the HDD for file storage. It’s quick enough to play off of, but not quick enough to be used solo.

    Golden Review Award: 10 From Our UsersAfter reading that it is ranked in top 30 fastests HDDs out of more than 1000 by Userbenchmark, decided to buy (54, April 2020). Please take a look at the comparison of my old and new HDDs, photo attached( Barracuda is Top, WD Blue 500gb is bottom) I am not too technical, but although the speed of this Barracuda is no match to an SSD, it is beating my old WD by far in reading speed. It is a bit quieter too. Reliability-wise too early to say, will update in the future. 4 stars because this HDD is SMR type, which means slow-ish writing speed. Please see below for differences:

    PMR: Perpendicular Magnetic Recording
    This is the technology inside of most hard drives. With PMR data is written to and read from circular tracks on a spinning platter.
    SMR: Shingled Magnetic Recording
    This type of drive overlaps recording tracks to store data at a lower cost than PMR technology. The downside occurs when data is deleted and that space is reused. If existing data overlaps the space you want to reuse, this can mean delays in writing the new data. These drives are great for archive storage (write once, read many) use cases, but if your files turn over with some regularity, stick with PMR drives.

    4.0 out of 5 stars 2TB 3.5'' Barracuda SMR HDD. Fast reading, but not writing speed.

    I purchased this 8TB drive as a backup volume to replace a dying 4TB Seagate drive. It arrived earlier than estimated, well packaged, via Royal Mail, requiring a signature. The drive seems to be a good basic model. Inspection with SeaTools and CrystalDiscInfo found no problems and verified that it was brand new. It came pre-partitioned in NTFS into 2.1 and 5.1 TB sections (7.2TB is all the usable space on any 8TB disc when it is formatted, alas), but it was two minutes work with the freeware version of AOEMI Partion Assistant software to make it one large volume as I wanted (lots of other free software is also available and would presumably have done the same as well).

    I wanted this drive to work on an old 32-bit Windows XP operating system, and as many people have discovered, XP can’t see hard drives bigger than 2.1TB. However, in the old days Seagate (and others) got round that by including a cunning little chip in the “bridge” hardware in their external hard drive cases that fooled XP into thinking that 4MB clusters were 512K clusters and, well, short version is it allowed XP systems to see bigger volumes – like my 4TB drive that was failing. So I swapped out the old 4TB drive inside that Seagate case with my new 8TB one, using the same bridge, and… hey, presto, my XP system is happy with its new 8TB (well, 7.2TB) hard drive! I empahsise that this would only be possible using that generation of drive cases pre about 2016 that includes the little wonder chip. I’m hoarding mine like gold dust. This trick with that bit of tech should theoretically let XP see drives up to just under 17TB.

    Anyway, so far I’m very satisfied with this purchase, which came promptly and did everything a budget large hard drive is supposed to do.

    Formated 14TB drive and got 13.7TB out of the HDD.

    Why Your Hard Drive Shows Less Space Than Advertised

    If you’ve paid attention to hard drives, USB flash drives, and other storage devices, you may have noticed that they always have less space than promised once they’re formatted. The reason for this difference lies in the way hard drive manufacturers advertise their devices, versus the way Windows computers actually use the storage devices. There’s also some overhead required when Windows formats your drive, for the file system and boot data, though in comparison to today’s large hard drives, it’s not a lot.

    To a hard disk manufacturer, one KB is 1000 bytes, one MB is 1000 KB, and one GB is 1000 MB. Essentially, if a hard disk is advertised as 500GB, it contains 500 * 1000 * 1000 * 1000 = 500,000,000,000 bytes of space. The hard disk manufacturer thus advertises the disk as a 500 GB hard disk.

    However, manufacturers of RAM don’t sell it in even groups of 1000 — they use groups of 1024. When you’re buying memory, a KB is 1024 bytes, a MB is 1024 KB, and a GB is 1024 MB. To work back from the 500,000,000,000 bytes above:

    500,000,000,000 / (1024*1024*1024) = 465.66 GB

    Keep in mind that the hard drive manufacturers are using the accurate description of the terms–the prefix giga, for instance, means a power of 1000, whereas the correct term for powers of 1024 is gibibyte, though it isn’t often used. Unfortunately, Windows has always calculated hard drives as powers of 1024 while hard drive manufacturers use powers of 1000.
    That’s a difference of nearly 35 GB over what the average buyer would be led to believe a hard drive contains. If hard disks were advertised in terms of the amount of space they actually contained when you connected them to your Windows computer, a 1 TB hard drive would be labeled a 931 GB hard drive instead.

    Alternatively, Windows could update their UI to use the correct definition of gigabyte–other operating systems, like OS X, have already changed their representation to correctly state the right amount of space.

    Golden Review Award: 2 From Our UsersYou might wonder why we need these traditional ‘old school’ technology hard drives these days. But now that I have one in my new computer build, it definitely makes a lot of sense.

    I am running the OS from an EVO PRO m.2 drive, so loading into Windows is almost instant, but running with a large capacity HDD compliments the rest of the storage requirements brilliantly.
    With a lot of games these days needing 50GB plus, this drive is the perfect answer for large Steam libraries if you are sick of juggling game installations on small SSDs.

    I would recommend the Barracuda PRO version over the standard one if you can afford it. It has a faster spin speed than the standard but it is still very quiet in that I cannot even hear it spinning’ I actually like the clicking sound it makes and it does not do it constantly as it did in the past where Windows was constantly indexing, or moving swap files. Storage issues have definately been solved in modern computers!

    You also get a 5 yr warranty which in my mind reflects on the superior components used over non pro drives. As for the price….well I have probably spent around the same amount of money on a hard drive or SSD in about a dozen computer builds since 1996, and the only thing that has went up is the capacity and the quality. My first build had a 1.6 GB ( yes thats GB not TB) drive and I remember how painful it was to manage the setup and space in these ‘bad old days’ of computing.

    It amazes me how the HDD technology has matured and even evolved to have a different purpose than it did in the past, and I do not see this technology dying any time soon. Unless SSD technology gets anywhere close to 6TB plus.

    Yet again time for another replacement drive for my laptop, 3rd time lucky! Previous drives have been both Seagate and Western Digital with all having a full working day put on them, from early hours to late at night, so a failure here and there is going to occur given the length daily up time and the intensive processes or programs I use and the length of ownership each time (2 to 3 years)

    The drive itself installed and loaded with Windows 10 just fine and so far has been working as it should. Not sure if a pending fault or just a little over active actuator but every now and then a slight metallic ping occurs which is timed around when writes are occuring. Time will tell what this is as I haven’t come across it on any of my previous drives, thankfully Amazon are top notch when it comes to faulty products so I am covered more or less.

    Performance is adequate with no problems in read or write time etc. Due to the mishaps of failed drives in the past a backup plan is now a dead cert. Thankfully Windows 10 has the ability to have documents auto sync’d to my One Drive with each of the other cloud services taking care of some of the items depending on topic and file size etc.

    From now on the adopted backup strategy for me to overcome any loss of valuable data is the 3-2-1 method. 3 copies of data, 2 on laptop and home server, 1 on 1 each, and of course 1 copy on the cloud / online services (One Drive, Dropbox, Googledrive). Hopefully, my data will now be able to be restored to their original state should another drive go down on me.

    Golden Review Award: 2 From Our UsersI read up on this product before hand and everything I read both on Seagate’s site and others said it should work with a computer running Windows 7 64 bit, so I bought it. Arrived on time and in good condition.
    When I fitted it into the computer, only 1.67Tb was found. I tried Seagate’s support department who were very good and very helpful, but nothing worked. In the end they decided that the motherboard in my computer just wasn’t able to handle the larger drive. No mention of that possibility when I was buying it.
    Fortunately, once I bought a PCI SATA Controller card and installed that, then plugged the drive into it, everything worked perfectly. Have had no problems since.
    It works fine, as far as I’m concerned it’s fast and quiet. But bear in mind if you have an older computer you might need to spend another few pounds on a card.
    I do wish HDD manufacturers would advertise their drives with the actual size you get. I know all the reasons why they don’t, why a 4TB drive is only actually something like 3.8Tb, but we wouldn’t accept that from any other type of company. If you bought a pint of milk and it only had 3/4 pint in it, you’d expect a refund. If you bought a 2L car and it was only actually 1.6L, you’d complain. But we all accept companies advertising HDDs at a size we never actually get.
