  • Worked Great on a Brand New 2022 MacBook Pro with the M1 Pro Chip
Style: Portable Capacity: 2TB
Worked Great on a brand new 2022 MacBook Pro with the M1 Pro Chip. It's amazing how cheap HDDs are now. I will continue buying them until the price of external SDDs goes down. You can literally get twice as much storage capacity with HDDs for half the price of a SSD. As always, with external drives used to do backups on Mac computers, you must reformat the disk before doing the backup and this WD is no different. Reformatting is a very easy task as always, and it takes no more than a few minutes to get the external drive ready for your Mac. However, I ran into some issues with Time Machine on the newest version of Monterey (the one that came installed in the laptop). It seems like it no matter what format you choose when reformatting the external drive, Time Machine automatically reformats the drive on its own to the new Apple File System (APFS) when you do your first backup. Not only that, but once Time Machine reformats the drive to APFS and completes the backup, then it blocks the HDD and you cannot use it to save anything else in it, drop files, etc. It basically locks the drive for backups only. Oh, and with the APFS format you cannot use the drive to backup older Apple computers. I NEVER had this happened in any of my Apple computers before. I tried a few other HDDs from other brands to ensure this was not an issue of the WD brand. They all did the same, so I knew it was an Apple software glitch issue. It took several calls to Apple to figure out that yes, Time Machine does this. The only way around this issue is to create a "new volume" in the external HDD. Then you can use the separate volume to save other things, drop files, etc. You could create as many volumes as you can, and the APFS makes it very easy. When you plug the HDD, the volume for the backup pops on your desktop (Time Machine color), along with any other volumes you created (yellow color). Hope this saves somebody out there a lot of frustration and aggravation trying to figure out what the issue with Time Machine and external drives using the newest Monterey version. I also hope Apple fixes this problem. It makes no sense that you select a specific reformat option but then Time Machine ignores it and reformats to APFS against your wish and block the drive in the process. The WD external drive works great. It is a really great value for 2TBs of storage, and it is a very small and lightweight drive. All the issues mentioned are specific to the Apple operating system that would happen with any HDD of any brand. ... show more

  • It works great. Enjoy a huge amount of storage for a reasonable amount of money.
Style: Portable Capacity: 5TB
TL;dr – it works great. Treat it with respect, be prepared to toss the cable it comes with (because they fail) and enjoy a huge amount of storage for a reasonable amount of money. You’ve probably read a ton of reviews on external drives and have arrived here. I’ve been in the tech biz over 44 years and was there when 128Kbyte 8” floppy disks were considered advanced. I’ve used a LOT of different drives. Let’s put this drive into perspective: it is NOT a “portable drive”, it’s an external drive that you can choose to move from place to place. AS WITH ALL SUCH DRIVES, it contains precision moving parts; if you drop it, it will likely break. If you move it around when it’s operating, it probably won’t like it. If you drop your laptop, it will likely break. If you want an external drive that you can really move around, get an SSD. I purchased one of these drives for cloud-storage and archival purposes. Simply put, I needed somewhere to dump large data collections for essentially read-only access as well as having a buffer area for cloud storage synchronization purposes (lots of r/w access to the drive). It worked so well I purchased another and might even get a 3rd. Cloud storage is great for frequently accessed data, but for your video collection, your vast music collection or the 130GB of pictures your spouse took last month, you might want off-line storage. This is a great choice. Is it fast? Slower than an SSD but faster than many external hard drives out there. If you want speed, use the local SSD in your device or get an external SSD drive. If you don’t want that expense, this is still a great drive. In operation the drive is whisper quiet and runs slightly warm. You may have read about the “click of death”, well, yeah, it happened to me too. It won’t run on an overloaded unpowered USB hub (click, click due to lack of power). The cable it comes with is frankly troublesome and honestly you should invest in a replacement. Yup, click, click, click because the cable failed (fortunately I had another to hand, doesn’t everyone?). All that will happen with other drives too, so it’s nothing unusual. My system: Win10 Pro and Win10 Home on Lenovo, Surface Books and Surface Pro; works out of the box just fine. For those complaining that the drive doesn’t work with some backup software; that’s not the drives fault. For those complaining about the speed for gaming purposes, that’s not the drives’ fault either, you should have purchased an SSD. Yes, it will work with Onedrive; just create a junction from your Onedrive folder to the required folder in the external drive. mklink /J srcFolder destFolder Since you have a large capacity drive for large data sets, robocopy (part of Windows) will be your friend as well as mklink to create junctions from your main drive to connection points in external drives filesystems. What happens if the drive goes down? As with any other drive, you might have lost your data. The solution is to (gasp) purchase two drives and sync one with the other. Pro’s: 5TB of storage for <$100. Quiet, fast and gets the job done. It’s a disk drive, it’s not there to be exciting. Con’s: I didn’t like the cable; invest $6 on a better one. As with ALL DRIVES, you need to treat it nicely. ... show more

  • Good drive! You'll buy it.
Style: Portable Capacity: 5TB
First order of business: I ordered this drive (WD Elements 5tb) and received it in about 18 hours. I checked the shipping label, and it is their proprietary delivery service. USPS, take note. The box it came in was pretty regular, no fancy presentation. Which is fine. I don't like paying for felt lining. It has one port on the back, and comes with a USB cable. I plugged it into my laptop and checked it out. Drive capacity actually reads 4.54 Tb. Which isn't unusual for larger volumes. It came formatted as NTFS. Which is great, because FAT32 has a file size limit of 4gb. Next test: I plugged it into a 3.0 Anker USB Data Hub. The drive revved up, then started clicking. I recognized those clicks as motor failures from a power drop, so the USB hub is not going to do it. This beast of a portable drive needs a main-line. It can be used in USB 3.0 or 2.0 But I highly encourage 3 for faster speeds. Especially with a volume this size (You are buying it for a reason, right?) Next test: A phone mount. Similar to a Samsung Dex setup, the device I used is a Baseus USB C mount. It connects my Note10+ phone to HDMI, and...for this test...a USB 3.0 port. I wasn't sure if it would work, because the hub charges the phone, and would have to "lend" some power to the 3.0 port to power the drive. It worked. I plugged it in, and my exFAT/NTFS app fired right up. It recognized the drive, mounted it, and was ready to go. For the technical folks out there, this was by powering the phone dock with a samsung travel adapter that came with my phone. It has a variable output, but can pack a whopping 11v-2.25a (24 watts) at its highest. This 24 watts was enough to fast charge my phone, AND have the drive running. Final test: Directly into the note10+. I used a USB C - USB A adapter that came with my phone and connected them together. It worked. My phone was powering the darn thing. So there we have it. This little pocket sized drive (seriously, my wallet is larger) can be plugged into 3.0, 2.0 or directly into my phone. It came formatted NTFS, just the way I prefer. Description: I purchased a black one. As I said, it is wallet-sized. It has one port for the cable, and a small status light. The light appears to stay a solid color for both standby and active. A power failure results in a blinking status light. When the drive is spinning, you can feel a humming purr, barely audible. The casing is plastic, but solid and sleek looking. It has four non-slip dots on the bottom. Pros: Huge storage for the price, powered through USB only, NTFS formatted, small. Cons: None discovered yet. Recommended Uses: This would be a perfect drive for home network storage, office/school/home work. It would also be ideal for gaming consoles even as modern as the XBox One X. Or a handy volume for torrents. Or a handy volume for backing up a system or family photos. Possible Uses: It runs on 3.0. While Pro Gamers might chuckle at the idea, it could be used as a Steam Library. Initial load times might be slower than a built in solid state drive, sure. But so what? This is 5Tb. Portable. For under 120. It could also be used for beginner-level production. Again, it is slower than a dedicated solid state drive, of course. But for a new youtuber, or designer, or developer...this can store a lot of content. ... show more

  • Reliable 5TB portable drive that just works – perfect for backups and extra storage
Style: Portable Capacity: 5TB
I’ve used a bunch of these WD Elements drives over the years, and this one is exactly what you’d expect – simple, no-frills, and it does the job really well. Plugged it into my Windows laptop and it showed up right away, no software install needed. Same thing on my Mac – plug and play, formatted it quick and good to go. USB 3.0 speeds are solid for a spinning drive – copying big video files or game backups takes time but it’s consistent and way faster than USB 2.0 junk. The 5TB gives you a ton of space. I use it mainly for Time Machine backups, storing old photos/videos, and keeping Steam libraries I don’t play often. Fits everything I need without worrying about space for a long time. The drive itself is pretty quiet – you hear a faint hum when it’s working ... show more
