Seagate Expansion 12TB External Hard Drive HDD - USB 3.0, with Rescue Data Recovery Services (STKP12000400)

I bought this drive (10TB version) to use as a media storage device for my Plex server. I run my Plex server on an older (2013) apple iMac that is running MacOS Catalina. When I first unboxed the drive, it looked nice, but when I plugged it into the power and then the USB on the back of my computer, it wouldn't show up. I couldn't get it to show up in my Finder window, on my desktop, or even in Disk Utility. I did all the tricks to show all drives and all volumes, but it just didn't even recognize that it was plugged in at all. I read some of the other reviews, lots of people complaining about how it wouldn't work on their mac etc..., I thought that maybe I was going to have to return the drive and figure out something else (it comes preformatted in exFAT, but as I said, MacOS Catalina wouldn't even acknowledge it was plugged in at all, so there was no way for me to reformat into the the system I wanted). Luckily I had a Mac Laptop with BigSur installed. On my laptop, it didn't show up in Finder or the desktop at first, but it did recognize it in Disk Utility (again, you have to set it to show all drives and volumes in the view). There I was able to select it, then reformat it as MacOS Journaled (or whatever file system you wanted, but that is what I use on my older Mac). Once I did that, I was able to plug it into my older Mac, and it showed up in Finder, Desktop, and Disk Utility. I actually reformatted again on the old mac (just to be safe, but probably not really needed as it was reading, I just wanted to make sure it would work on the old mac the way I wanted it to). As I'm typing this, it's just finishing backing up the 4TB of media from my old drive, it's been whirring away for about 24 hours now, no problems so far. So as long as you are willing (and have the newer macOS available), then this is a great external hard drive for Macs, just don't expect it to work natively right out of the box (but external hard drives rarely do). That being said, I am happy with the price and performance so far, hoping 10TB will last me quite a while (my old drive was 6TB and I thought I would never even come close to filling that up, but I don't like to run my drives too full, so using 4TB out of 6TB was more than I liked, so this 10TB should fit the bill nicely for a while anyway).

This was purchased 5 years ago and still going strong having travelled the world 3 times and this last weekend tumbling off the table onto the beach

My only issue was that after I copied all my backup files to the disk after the seamless plug-n-play, I rebooted my computer and the exFat format on the disk caused my reboot to hang up on the manufacturer's logo. I contacted Seagate for support and they did not realize the issue so were having me test on other machines and the cord, etc. Lots of time to do all that troubleshooting. Found my answer by searching that someone had reformatted from exFat to NTFS and solved the issue for them. So, I erased all the work I did and reformatted and it booted right up. Seems to serve it's purposed to hold backup files quickly and easily. The one I'm replacing is a Seagate and have had for years and still works. Just too small at this point. I'll repurpose.

I bought this product to store photos and extra files off my computer. I was excited that it was easy to set up and began to transfer files. 24 hours after connecting the HD to my computer, the HD began to operate very loudly. I couldn't understand why it had suddenly gotten so noisy. After 48 hours, the hard drive was no longer recognized by my computer. I also noticed that the HD was no longer powered up...so I rebooted my computer several times, unplugged and replugged the HD several times, tried a different power outlet and also tried a different power cord from a similar hard drive....but nothing worked to get the HD firing back up again. The HD was officially dead. I contacted customer service to simply be told that I was likely out of luck but that I could send in my hard drive for an attempt for data retrieval. The entire process would take roughly 30 days. Well....after 60 days, I reached out to them asking on status and they told me they needed more time. Finally last week, they contacted me (after having my HD for over 90 days) to inform me that they were unable to retrieve my data and would be sending me a refurbished HD. What kind of business model is this? You sell me a $400 piece of crap HD that only works for 2 days, lose my data and then give me a refurbished HD in return??? For those of you looking to purchase an external hard drive, please spare yourselves the pain and agony of purchasing this product. If I could rate this 0 or less, I would.

About me: 25+ years in the IT industry covering enterprise storage and among other things. Only saying this because I understand the product I'm reviewing. That said: Great price on a gob of external storage. Reasonably quick access times for desktop use, I wasn't looking for a barn-burner, just something to hold digital media and backups. This does the job nicely. However... Out of the box, the thing goes into sleep mode. A *lot*. The net result is that it makes your Windows PC slower, because it has to spin up EVERY TIME you access the file system. Downloading something? The "Save As" box takes a lot longer to appear, because the drive has to spin up. Looking for that picture of your kids and you on a holiday to upload to social media? Wait a few seconds, because the drive has to spin up when Explorer gets activated. Over time, this adds up and it's frankly unacceptable. This problem has a resolution, though. Download the Seagate Dashboard software and set sleep time to "never." I really think this is a crap solution though, I have to download a 150MB+ application to simply make the drive behave like almost every other external drive I've ever used? Dumb, Seagate, just dumb. It takes a star away from an otherwise solid product.

I own a mixture of trashiba's, Western Digital's, and Seagate's. I purchased this over WD based on price alone. It wakes up just as slowly as a WD and performance-wise, I don't see any difference. I am getting a constant 163 Mbps plus, sometimes it starts out at 233 Mbps and then falls down to expected levels. I will buy a second one in the near future. Oh, it's slightly a bit noisier on startup than my other Seagate drives as it spins up. I have it standing on the edge, like the rest of my bricks, so maybe that's why. Glad I purchased it. ]: )

Works well

This review is for the Seagate Expansion 16TB External Hard Drive HDD - USB 3.0 There's nothing special about it. It's just an external disk. They will either fail in the beginning or last a long time. I'm still burning it in and so far so good. I've been buying Seagate over the years because they included Paragon NTFS for Seagate, making it useful for Macs too. I didn't actually pay attention if this one had it before I wiped it, since I already had Paragon on Mac. I think you can get it from Seagate's web site if you hadn't installed it yet. I usually just attach it to one system these days, usually Windows, and share it to the others. I just leave it as NTFS, since it's a much better file system and more useful, since it can hold Mac files, including old files with Resource Forks, without needing them to be zipped up. The NTFS versions also cheaper than the Mac formatted versions. If you really need it to be Mac, just reformat it on a Mac. The only really bad Seagate disks, so far, were those old 1.5TB and 3TB batches. But most of the other sizes have been reliable. I just buy the cheapest one per TB at the time of purchase for my home backup. My previous one was a Western Digital 12TB, and the one before that was a Seagate. it's whatever was cheapest at the time. I generally buy single disks for backups, because they're much easier. It's also much cheaper than RAID and less overall maintenance for my needs. I usually buy a new single disk about once every 3 years +/- and start copying my previous disk contents to it and keep the old disks as backups. That way I don't lose data if one disk fails. Long ago, you needed to do that every 3-5 years before a disk actually fails. These days, they're lasting longer than the typical 3-5 years because they go into sleep mode when not in use. I've had older disks under 750GB fail on me, but other than a 1.5TB Seagate, I haven't had these disk fail in a long time. My 2 TB Seagate is still running fine. Of course, these are basically low use backup now.

Muito bom

Ottimo prodotto. Affidabile, veloce e piccolo. Top 🔝

Seagate Expansion Desktop 12TB, External Hard Drive, USB 3.0, 2 year Rescue Services. As a photographer, I store tens of thousands of images. I use cloud services for backup purposes, but I also want local access. This drive is ideal. I can get consistent transfer speeds from an SD card to this drive at 150MB/s. The device has negligible fan noise at all times. There is some write-head noise when writing large numbers of files to the drive, but this is unlikely to be a common task for any extended period. Even then, the noise is not much louder than typing on a keyboard. I have several Seagate high capacity drives for many years and to date none have failed. Here's hoping it stays that way.

For the 16TB it's a EXOS X16 inside. Great HDD. Shucking is easy. You don't have to deal with the 'pin problem' from shucking a WD external drive. The WD drive from shucking is not really great quality anyway. In case you are using it as external drive, the box comes with multiple plugs that should fit most countries in the world.

12TB を購入しました。外付けHDDなので中身が気になっていました。 ヘリウムならIronWolfでもなんでもいいと思っていましたが。 CrystalDiskInfoでST12000NM000Jが表示されたので、EXOS！なんか得した気分です（笑）
