    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: 3 From Our UsersMy pc does not have the best fans but even in silent mode the hard drives are definitely the loudest noise source. If you don’t mind the ambient noise they produce, they work great.

    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: 2 From Our UsersI recently purchased this 4TB hard drive and I am beyond impressed. I have so much storage now and the transfer speeds are super quick. I haven’t had any problems with it so far and it’s been really reliable. I highly recommend it to anyone in need of a lot of storage. 5 stars all the way!

    Golden Review Award: 3 From Our UsersThis hard disk came well packaged. I installed it into my PC but it wouldn’t assign it a letter so I couldn’t access it. I found the solution was to press the Windows key + the X key at the same time, then choose “Disk Management” from the popup list. There are lots of options in Disk Management but I simply right clicked on the disk which was shown in the list of disks and formatted it, then assigned it a letter. This creates a stand-alone disk but you could create virtual disks, spanned disks, striped volumes or partitions just as easily. Note that clicking on the box on the left gives different options to clicking on the box on the right.

    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: 13 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

    Hooray! A hard drive arrives undamaged because it has been packaged securely. Around 3.7 gb of useable space after formatting. Will do the job as a bulk storage drive

    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)

    Installed without an issue. Too new to comment on longevity. Slow compared to SSD but perfectly fine for storage purposes. Will see how it performs as time progresses and disk becomes fuller.

    Golden Review Award: 17 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.

    Very happy with this HDD now that I have it working, two comments which might help others…
    1 There are many reviews saying the store capacity is not 4Tb eg it’s 2Tb and many saying the drive was doa (dead on arrival). I don’t know why Seagate and/or Amazon don’t provide simple installation instruction – it took me some hours to fix – after installation, drive was not visible in W10; entering setup, I could see it [setup doesn’t provide much information or options to fix anything]; the eventual solutions were both in disk management – windows command DISKMGMT. Firstly select GPT option, otherwise available space will be limited to ? 2 or 3 Tb; secondly all space was marked as “unallocated” – right click on the drive and select “new simple volume” – I let it allocate the maximum – drive then visible to W10.
    2 Previously I bought an external 4Tb drive – my files are mostly in OneDrive, but to watch eg video there is very slow download; so files really need to be mirrored on local disc. This didn’t work – as OneDrive will not sync with an external drive.

    I got this to replace an ageing 5Tb drive that was emitting SMART errors. Initially I purchased an IronWolf drive, but it was packaged so poorly that unsurprisingly it was faulty and started throwing errors after less than 30 minutes use! Rather than try that again, I thought I’d try this.

    This one was packaged pretty poorly too – it was a dice-roll whether it’d survive the bumpy van ride to my house, but survive it did! I ran a quick SMART check and set about transferring roughly 4.5Tb to it. The process is sloooooooow as it’s a 5400rpm drive, with most transfers averaging around 50MB/s write speed (which is about 400 Mbit/s in Internet speak). Enough for what I need, but slower than my internet connection.

    In hindsight I would opt for a 7200rpm drive, but this is a case of buyer beware more than anything!

    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

    I bought this 2TB drive to put all the junk I didn’t want slowing down my Windows 240GB SATA SSD, or my 1TB NVME Gen 3 M.2 SSD.
    I’m no technical whizz but when I benchmark it, it says “cached drive detected”, or something to that effect, and refuses to benchmark the result. Regardless of that it’s a FAST HDD. I can feel the difference in the loading times from my trusty old Western Digital I’ve had since 2013.
    If you have a gaming PC with a couple of SSD’s and don’t want to clog them up with the stuff you need but don’t use that often and loading times aren’t a big thing, this is perfect. Plonk all your bloatware on it, stick your anti-virus on it, plus any games which don’t require a speedy SSD. You can never have too much storage space, but you can certainly have too little.
    I’ve heard that the Barracuda’s don’t last as long as some other brands like WD, but I’ll be the judge of that. I’ll edit this if a find any issues with it, but so far so great!

    The packaging was just an antistatic bag! Okay – it was part of a multipart order in a jiffy bag but I had hoped for at least a cardboard sleeve. (Amazon??! :o)
    Anyway – no SMART errors and a pleasing spinup count of 0.
    It’s a little slower than its 3.5″ 7500rpm cousins but I’m just teaming this up with a 500GB ‘system’ SSD so I’m not too bothered. In the USB caddy it’s hard to see what transfer rate I can really get. It will be internal soon so I will try and get back to the review and update it.
    Update – internal on a SATA connection it managed about 60MB/sec continuous write for a very large file on a partition that’s towards the inner part of the platter (Win10, NTFS, default settings). It peaked at 110MB but that’s just on-disk cache filling up.
    Not brilliant but perfectly adequate. If you want higher transfer rates, pay more – this was a budget purchase and it ticks that box. There are some good bytes/pound deals amongst the 2-4TB 2.5″ spinning disks this summer (2020) if you’re after a backup drive.

    I wanted to have an additional physical drive in my computer case for convenience for storing games ect where I may be moving things on and off a fair bit and be able to format as and when. This drive is perfect for my needs and works very well. The only problem with installing any additional internal drive is that although it shows in bios Windows will not show it until it is formatted and assigned a drive letter. I had to disconnect my existing drive and boot my pc with a Windows 10 disk and begin the install process to get the new drive so Windows could see it. I aborted the install, turned off the pc, re connected my existing drive and the new drive was visible after a reboot. I could then use the “partition” command at the start menu and create partitions and name each as individual drives. Format them and enjoy having the additional space which won’t be compromised if I have to format and reload my main disk containing the operating system.

    Golden Review Award: 235 From Our UsersNot much to say about this 2TB drive other than it works as intended, however have recently discovered that this is an SMR drive. I bought this specifically to replace my old Barracuda backup drive so it is fit for purpose. A word of warning to those looking to buy this drive as a system drive however, avoid. You should look to find a PMR drive instead.

    Seagate Barracuda Compute drives in 2TB, 3TB and 4TB are all SMR. The 1TB Compute drive is PMR. Barracuda Pro drives are all PMR, hence the inflated price. Do not be persuaded by the 256MB cache, this offsets the drop in random read/write speed associated to the SMR drive. Seagate do not disclose which of their drives utilize SMR and have removed this information from their datasheets, so I hope this informs your purchases.

    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
