    Kaufe Western Digital HD's seit über 20 Jahren und 0 Probleme
    Leute kauft nur WD oder SAMSUNG. Ich habe nur WD HD’s zur Datenspeicherung und fr Back-Up’s. Habe letztens eine SAMSUNG SSD gekauft, auch nicht schlecht. Kann keine langeitanalyese hier geben. WD ist absolut safe.

    Lento ma sicuro
    E’ un Western Digital e questo marchio continua a dimostrare la sua affidabilit. E’ solo un p lento esendo abituato agli HDD da 7200 giri al minuto ma per un’unit di backup pi che sufficiente.
    E a me serve soprattutto l’affidabilit.

    Buon Prodotto
    Temevo per la spedizione, un guasto dovuto ad un urto durante il trasporto sempre dietro l’angolo.
    ma Grazie al triplice imballaggio tutto con pluriboll e scatola fatto dal fornitore , arrivato sano e salvo .
    eseguito test verifiche, tutto ok , mi ritengo soddisfatto .
    pecora nera il corriere, tracciamento ? bho? sono andato a ritirarlo di persona, consiglio il fornitore di valutare altre opzioni.

    Slow but working fine so fa
    This HDD has great storage since it is 4TB. I have been using it on the NAS and what I realized is that its pretty slow to read and write the data.
    The issue with this drive is the speed. Everything else is working fine so far for months of running it 24/7.

    I purchased this Western Digital 4TB WD Blue PC Internal Hard Drive to store my movies. Since DVD's are going out, I have put everything on my computer. This hard drive updates my last smaller Western Digital Hard Drive that has never had any issues in the last few years that I have used it. I will delegate the smaller hard drive to backing things up, and use the new one until it fills up. I recommend the Western Digital 4TB WD Blue PC Internal Hard Drive!

    Have bought a few WD hard drives. Never had any issues , some of the very old ones maybe a bit noisy now but still functioning fine, so a no brainer when needed a new hard drive.

    Buen disco duro
    Me llego algn da antes de lo previsto, el disco vena dentro de una bolsa de burbujas donde la mayora estaban pinchadas y a su vez dentro de una caja de cartn demasiado grande, con lo que el meneo que debi de recibir lo considero de importante, no entiendo como un producto tan delicado se trata como si fuera una pelota. El disco funciona bien, hace un ruido raro al desconectarlo con lo que desconfi de su durabilidad, siendo esta marca la que siempre utilizo para almacenaje porque me duran muchos aos. Lamentable el sistema de embalaje

    This seems to be a trend with manufacturers. Item states it’s a 4Tb drive however in reality you will only get 3.6Tb of actual storage. Still a lot of space. However, a bit of false advertisement in my opinion. I could use that extra 400gb.

    Golden Review Award: 3 From Our UsersDependable storage drive.
    I’ve had mine since fall of 2019, and it’s still doing fine. I use mine as a storage drive, nothing very demanding.

    At 5400 RPM, I don’t think this would make a very good gaming drive. You’d experience some hefty load times. 5400 is just fine for storage though. Videos, pictures, projects, whatever. A cheaper solution for your mass storage needs.

    This is an internal HDD, not an external, so installation is required. It’s a simple process as far as PC building goes, but if you’re not comfortable opening your case to mount it and plug it in, you might want to consider an external one for your storage needs. Those just need to be plugged into an outlet, and a USB port on your computer. It is pretty easy to install even if you’ve never done it though. It’s only going to fit in a couple places, of which you can use any of those slots. Power and data cables are pretty goof proof too. They’re designed so only the proper cables will fit, and only the right way. I’m sure you can find a few dozen videos online to help you with this.

    It’s been installed and is working as advertised. We’ll have to wait to see if the drive lasts the way it should. It should last for years, here’s hoping it does.

    I put this into an external SATA, 4 bay, 'USB3 drive docking station', that I have been using for many years to offload and backup files from my desktop PC on a Windows OS. My current OS is Win11 Pro 22H2, and the installation was very easy. You will likely need to call up the Win disk manager to initialize and format this drive. I'm happy :)

    Great for storage, speeds are very slow.
    Great for storage, speeds are very slow.

    Great if you need to store big files that you touch rarely, you know – old picturesvideos.

    Definitely should not be used as a main drive if you are doing anything that requires high read or write speeds.

    The drive arrived in typical packaging, anti-static bag with desiccant, and in perfect condition. I used it to replace a wounded drive in one of my NAS mirror sets. Restored 1.5TB of data to the new drive without incident.

    Western Digital 4TB WD Blue PC Internal Hard Drive HDD – 5400 RPM, SATA 6 Gb/s, 256 MB Cache

    Got it unformulated which is no big deal formatted – however total functioning capacity is around 3.6 TB. Don’t know how long it will last but so far so good. Speed is decent. Bought it for main failsafe backup drive for everything and assume it will work perfect for that purpose for a few years at least.

    Easy to Use and Relatively Quick
    Having been fed up with a 2TB pencil drive not being compatible with Windows 10 (don’t you just love how Microsoft tries to control your life?!!!) or not working properly with the Mac, I decided to get another Western Digital 4TB drive. They continue to be the world leader in drives. Although this is an internal drive, I didn’t want to pay the more expensive price for an external drive, plus my Mac is old (2008) and the connection is USBA, so the latest external drives would likely not connect. I therefore use this drive in a docking station and it works fine. – I play music live from this during my radio shows, loading to the playout app.

    For me the SSDs of this capacity and greater need to come down considerably in price before I will switch over to them. I therefore use great HDDs like this and they work fine.

    buon prodotto
    fa il suo lavoro senza problemi. riconosciuto immediatamente dal PC (con w10 ti viene indicato le modifiche di impostazione per poterlo formattare e riconoscere). buona la velocit di scrittura (con usb3 siamo quasi a 200 mb/secondo). per adesso tutto ok. comprato per cambiare un disco in un nas a 4 dischi ed utilizzato per archiare filmati. naturalmente non silenziosissimo ma rispetto alla serie green di wd si percepisce un po’ meno.

    Golden Review Award: 3 From Our UsersI have four SSDs with large files. Everything is great, until I need to clear off a large amount of storage to reorganize a disk. I end up deleting backups that I "probably" won't need. I got this 4TB HDD for pocket change. WD Blues are one of the most reliable drives too. Now I can easily move large volumes of files to this 4TB HDD as a work area or archive. It never fails to amaze me how incredibly slow HDDs are compared with the NVME SSDs. So I start the file copy to the HDD and take a break, its done when I get back.

    It's a recertified drive.
    When I was fitting it, I noticed “Recertified” and a couple of Chinese/Japanese characters etched/stamped onto the side. Not glaringly obvious. I wonder whether this might explain the relatively large number of failures being reported. Drive seems to be working, but I’ll have to see how long that remains the case. Don’t know what the warranty period is on recertified drives. I feel the seller should state it’s a recertified drive.

    The price of these is usually low enough to consider buying them new for off-line storage. Something most people don't consider using a hard drive for. 4TB has become small for my purposes, but as off-line storage I don't want to risk more than that on one drive. It's much simpler to archive data on a 4TB hard drive in a dock and keep it in a case than to burn 4TB to a stack of Blu-Ray disks every few months, and DVDs are completely out of the question. I'm archiving around 20TB of 4K video that I've captured with GoPros so far. Most of it is on "retired" drives, but I've run out of reliable older drives and I think I'll be upgrading to these in the future. They're unlikely to store data forever without some degradation, but rewriting the data once a year won't wear them out for decades. These will not work well in an NAS or even a RAID array in a PC, and shouldn't be used in a PC with more than one or two hard drives anyway. They're not designed to cope with vibration from several other drives, but as a single drive or for data backup they're fine. It's a capable drive for typical home use. For full-time use in an array, the Red Plus and Red Pro drives are what I get. If you need to store large amounts of data off-line, or if you just need a new drive in a home PC, this is a good choice.

The value for money was the best at the time, and I was not looking for amazing performance since I use my SSD M2 if performance is needed. I recommended this disk for storage purpose only. Also , please make sure to save important files on the cloud / NFS since hard drive are known for failure. I only store non-important stuff on this disk and so far it's been great.

    This one is odd though it is always doing something, is never at rest. Not that fast either. Have an old 500GB Blue drive that runs circles around it and stops when the job is done.
