    Be mindful that when you first allocate the drive that it splits into 2 2TB ish partitions.
    Just create both partitions as GPT then merge the 2 together to have access to the whole drive 4TB 🙂

    They make no noise and have the same storage. They state no catches and work fast overall I cant argue they are good and probably the best you can find for the price.

    Its not a bad hard drive but maybe because im used to using SSDs it seemed quite slow. Maybe for secondary drive would be ok.

    What is there to say? It’s a Hard Disk at the end of the day with a lot greater storage than I already had. However, it arrived very quickly and works like a charm. I am lucky in that I was able to image my old disk drive onto it, but it went flawlessly. It’s a SATA disk so it’s a little noisier than an SSD but I already knew that and there is something quite soothing hearing it whirring away knowing that it is functioning correctly. It’s a cheaper option too so it suited my budget.

    Had a failed drive in my buffalo nas , and was running a older version of this drive . This one was a direct swap and within minutes was rebuilding the RAID

    Needed to replace a similar drive that failed a few months after the warranty period ended. Have a number of them in a few systems and they seem to have a fairly good lifetime. This was the best priced at the time so bought it.

    Using this in a secondary NAS for video files. I’ve used Barracudas in the past and none have let me down, although they don’t run super quiet. For for my primary NAS with more important things I’d only use a dedicated NAS drive.
    Not too bad for the money but prices are still falling per Gb.

    Golden Review Award: 9 From Our UsersI have used Seagate Barracudas for 12 years and found them to be a fantastic all-rounder, having great reliability and lifespan. I use them both in the house network drives and the Home Theatre library. I have even committed the cardinal sin of changing the orientation of a set of three year old barracudas from horizontal to vertical, when the library enclosure backplane failed, and they just continued on in the new enclosure with zero errors. Most of my Barracudas run 24/7, and on average they last for 8 years. But even as they get to end-of-life, they have never just failed, they begin throwing up the odd error, to let you know they are almost done. In my experience, you have about three months from the start of the drives giving errors, to more serious problems. But if the drive is around 8 years old, it has pretty much done it’s duty. The only thing I would warn you about, is to make sure that the barracuda (or any Seagate hard drive) arrives in the proper Seagate transit box shown in the pictures. This is the official Seagate packaging, and will include the Seagate warranty booklet. I mention this because I was tempted by a supplier that was slightly cheaper than the official Amazon-supplied drive. What I received was a barracuda inside a heat sealed anti-static bag, but it was loosely packaged in a generic cardboard box without a warranty card. These drives are sometimes ‘harvested’ from other devices, such as Seagate Expansion or Backup units. I returned the drive and bought the slightly more expensive official Amazon-supplied drive, as these always arrive in mint condition. I will not make that mistake again. The official Seagate boxes suspend the hard drive on all sides inside the box, helping to ensure it arrives in perfect working order.

    An excellent hard drive. Just make sure it arrives in the correct transit box with a warranty card.

    bought this drive to replace my older model of the same brand….

    After installing (very easy) and set up on my computer noticed more noise coming from the drive than the pervious model when writing and reading.. and think when it goes into low power/standby and comes back on makes bit of noise.. other than that does as it says…

    Dont think its faulty.. or duff drive just think its little more noise everything seems to check out…

    Overall would rate this drive very good

    I bought this 1TB HDD as secondary storage for a self-build Windows PC which also has a 250GB SSD. This disk was a replacement by Amazon for another of the same type which I couldn’t get to work, and didn’t show up in Disk Manager or even in the operating system if I used diskpart followed by list volume. Well done Amazon for replacing the product so quickly. Out of the box, this HDD did show up in Disk Manager and Device Manager (but not Windows File Explorer or diskpart/list volume). I carried out a quick NTFS format using Disk Manager, labelled the volume, and then the HDD was up and running, showing in File Explorer etc. So far the HDD is performing well and speedily, and the purchase was good value. Great customer service from Amazon too.

    Fantastic for storage and speed (for a HDD). It will never compare with an nvme drive. However if you’re storing large amounts of games, video’s, movies or photos. This is fantastic. I keep one in my PC along with a 1tb nvme and I’ve not ran out of usable storage yet.

    Golden Review Award: 5 From Our UsersI dabble here and there in content creation and I found my hard drive would fill up very quickly when encoding videos at a high quality. I have found this product to be a great way to solve the problem I was having. I’ve now used this drive for almost a year and it has been nothing but consistent. Files load fast (not SSD speeds but that’s to be expected) and transferring large quantities of files between drives has been quick and painless. For gaming, this drive is adequate but you wont find the blistering speed you’d expect with M.2 NVMe drives.

    I would recommend this drive for storage more than anything else, but that doesn’t mean that there is no versatility to this HDD. It’s a great quality product, quick to setup, and I’ve observed no drive errors in the time I’ve owned it.

    If anyone gets this drive, installs it, and can’t see it in your list of available storage, make sure you format and mount it using Disk Management on Windows devices.

    Golden Review Award: 4 From Our Usersot sure if it’s the norm for HDD manufacturers to not include screws or cables with the item but mine came with neither so i am going to have to order some screws. wish i had known before

    Golden Review Award: 2 From Our UsersA little overpriced in my opinion without a sale but its a trusted brand which ive had no issues with in the past, no issues to report with it so far my only criticism would be the packaging for the size of the HDD itself the box is about 10 times larger and has no shockproofing measures to speak of.

    Golden Review Award: 14 From Our UsersI’d just like to interject for a moment. What you’re refering to as Linux, is in fact, GNU/Linux, or as I’ve recently taken to calling it, GNU plus Linux. Linux is not an operating system unto itself, but rather another free component of a fully functioning GNU system made useful by the GNU corelibs, shell utilities and vital system components comprising a full OS as defined by POSIX.

    Many computer users run a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely used today is often called Linux, and many of its users are not aware that it is basically the GNU system, developed by the GNU Project.

    There really is a Linux, and these people are using it, but it is just a part of the system they use. Linux is the kernel: the program in the system that allocates the machine’s resources to the other programs that you run. The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called Linux distributions are really distributions of GNU/Linux!

    Good for GNU Slash Linux

    I needed to increase the storage capacity of my small NAS drive from the existing 1Tb drives. Like everything, you get what you pay for and I compromised on these 2 2Tb drives (in mirrored RAID) rather than spending 2x as much on 4Tb drives. Really easy to install (there’s nothing to do in reality) in about 15 minutes and then most of the day copying data back on. Been running about 4 weeks so far non-stop with no issues (although this is very early so far) but will reconfigure the NAS drive to power off over night as I don’t need it then)

    Golden Review Award: 18 From Our UsersThis is a great drive or a horrible drive depending on your use case!

    Pros:
    *Great storage capacity
    *Reasonable read speeds
    *Well packaged
    *Passed all memory tests on arrival
    *Very cheap for the storage capacity

    Cons:
    *Shingled Magnetic Recording drive
    *Slow write speeds (Considerably slower than Conventional Magnetic Recording)
    *Incompatible with NAS arrays

    Do buy this if write speed isn’t important to you, for example If you don’t plan to use any form of linked storage like NAS arrays etc. SMR is incompatible with NAS.

    This will work well as a steam game library if you play simple smaller games that aren’t regularly updated. If you play games which take up 200 gigabytes of storage space and get updated every week please avoid. SMR drives overlap data, meaning that writing information needs to be overwritten as many as 3 times over instead of once with CMR.

    Check your potential purchases against a list of known SMR drives (this technology applies to all manufacturers, not just seagate) for peace of mind. You may well kick yourself later if you don’t.

    This storage is great for storing files, media and games. However, I would recommend an SSD if used for gaming, apart from that, this HDD comes at a good price per GB and a reputable company.

    The box it comes in is thin cardboard, and the HDD itself is wrapped in a plastic bag, I think it could have better packaging to protect it more.

    7/10

    Golden Review Award: 2 From Our UsersTldr: drive is big enough for an average steam library + some video clips etc. Not extremely expensive and not too loud. Overall it’s pretty decent and if you can’t shill out for a ssd this is a pretty good option if u already have a boot drive!

    In depth:
    This was a good midground between the 50 pound 2tb option or the 8tb option.
    It’s enough that you can store plenty with an m.2 as a boot drive for most gamers or small time content creators. The drive can run any game I throw at it with no frame rate hitching and there’s only greater load times by a little.

    Be warned that I use this for steam titles and video / lesser accessed files storage. Things like my browser, discord etc I keep on my m.2 otherwise it is annoying when the file is a few 100gb apart in storage and it takes a second to load.

    Golden Review Award: 3 From Our UsersI’ve seen people in the reviews say this hdd is a moo4 not a moo8 which means, it is 7200 rpm and it’s faster than a standard hdd. At least it is for me.
    It came with protection in the box, the Amazon delivery decided to throw my hdd over my back fence which I was mad about, but it was working fine so I cba to report it
    Ofc this is a hdd so it will make some sound but after a week or two you get used to it and it doesn’t bother you, but if you want little to no sound just go for an SSD

    Review 1.
    This 3.5″ Seagate Barracuda 2TB is a basic HDD without ‘hybrid’ SSD enhancement, thus not fast enough for gamers or a modern PC. It also uses SMR technology, another reason why it should not be a system drive on a PC. The speed ratings were about right when I checked it on my PC.

    Installation is as standard. Capacity is the usual amount. Power consumption seems to be as usual.

    The drive arrived well packaged in its antistatic bag deeply cushioned inside a complex folded cardboard box, all very green, no polystyrene anywhere.

    However, my application was in an old Humax HDR-Fox T2 because its HDD was approaching full, and was therefore moved across to an external caddy for occasional access. This new 2TB drive is working consistently in the Humax. The video files are all large, consequently fragmentation is less of a problem than with a PC, and the Humax data rate is sufficiently slow an SSD is not necessary.
    .

    Review 2.
    I also bought a 2.5″ drive, so Az forces me to review it in the same section!

    The Seagate ST1000LMZ48 2.5″ 1TB BarraCuda is a modern simple high speed hard-disk drive with a 128MB cache. It is not as fast as a Hybrid or an SSD. I bought it for use with a rotation-set of colour coded weekly back-up caddies stored off-site so absolute speed is low on my list and SMR is not a problem with wipe all and rewrite..

    Drive Management in W7P or W10P formats the new drive in less than half a minute, giving an NTFS formatted working capacity (non-bootable and without O/S) of 1,000,068,635,870,144 bytes (931GB).

    After a thorough search taking some time the standard block check failed to find any bad blocks or sectors.

    Big file transfers are limited by the caddie’s USB3 interface but still approach the maximum speed of the drive at about 100MBytes/s write and 60Mbytes/s read, depending on how much directory access and fragmentation there is, even so I am very happy with this drive.

    My samples were made on 1st August 2021 in Thailand, bought 4th December 2021 in UK. Manufacturer’s packaging is a miracle of cardboard origami and the only plastic is the sealed anti-static bag the drive travelled in.

    Packaging was great. Some of the reviews here mentioned it wasn’t that OK, but this was being fulfilled by amazon (check when ordering), and as robustly packed as a hdd could be.. Stiff cardboard with a formed internal cage and minimal wiggle room. And obviously the anti static wrap.

    It is NOISY.

    I have another barracuda compute 2TB in my tower from a few years ago which is twice as thick as this one and almost silent by comparison. This one has a whine I can hear quite plainly though it’s housed in a pretty solid cage in a full tower PC.

    Works OK otherwise.. First thing this had thrown at it was a copy (freefilesybc) of roughly 1TB of pictures, videos, documents etc.., and it hovered mostly between 60-100MBps, with a few peaks at 120MBps. This is as real world a test as it gets for what I think this drive is OK for – backup, there’s some crystaldiskmark scores in other reviews here which can be better.

    Noisy whiny noisy little drive though when it’s going full tilt.

    4.0 out of 5 stars Well packaged, good value for backup drive, NOISY

    Golden Review Award: 4 From Our UsersBefore i talk about this drive i just want to say that i am not using this drive in a conventional way, i have it installed with a separate SSD that are linked through AMD’s store MI technology, using the SSD to accelerate the hard drive and act as a cache and if you are on a 2nd or 3rd gen AMD CPU i would highly recommend doing this especially for a game library as it massively increases loading times to more SSD levels of speed.

    As a driver for a steam library, this is nearly perfect, i personally bought the 3TB variant and it should give me more than enough storage for a good while yet. now i will say DO NOT BUY THIS AS A BOOT DRIVE, it might be tempting as youi get a ton of storage for little money compared to an equivalent SSD but it is not worth it. running an OS ANY hard drive will be infuriatingly slow and low capacity SSD are so cheap (256GB for 30-$50) there is no reason to buy this as a boot drive. but for a games drive or just general storage fro things you don’t need to access often this is perfect. it was easy to install in my gaming rig and the store MI setup was easy as well

    i would highly recommend using store MI for AMD and optane acceleration for intel to get the most out of these drives, they make a significant difference in access times and general speed. also do not believe the “190MBPS read and write” claim on the product page, that is sequential reads and writes which don’t usually apply to most people as most people dont work with single large files, for most programmes you’ll be lucky to see more than a few MBps. all in all, for the price, these are a great buy and the warranty is nice as well
