Customer Ratings & Reviews

the Seagate Expansion 34TB External USB 3.0 is a great addition to my other Seagate drives I use every day. It's quiet, fast and I know I can depend on it. For me it was easy to just plug & play. No formatting was needed for my PC. Quick set up and use is a big plus for me. I've had no problems with the drive and it is able to store 25+ years of photos and artwork with a ton of rum to spare. Download speed is fantastic. Love all my Seagate Drives. Never had a problem with any of them. Highly recommend the product to anyone who needs more hard drive space. Super happy with it and you will be too.

This external drive is both fast and also massive! Wish I'd purchased one sooner. The largest single drive I've ever had before this was 8TB. I back up our home server and each of our home computers onto this now, and it's perfect. Only con is that it does make some clicking noises when being used. This is not an issue for me at all, but something to note, and probably common with larger platter drives. Love it and will be buying more!

Giving this a try after using WD easystores for a few years because of the sale price for the capacity. CrystalDiskInfo reports ST24000NM002H-3KS133 which is a SATA Exos X24 24TB. CrystalDiskMark seems to be typical. Connected to a Dell Optiplex 5050 SFF. Connection is USB Micro-B. Was formatted exFAT, registered it (Start_Here_Win.exe) before quick reformatting to NTFS. All the easystores came formatted NTFS and I haven't had permission problems. Among other things, gives me more flexibility with the label name. Only had a chance so far to run chkdsk d: /f /r > chkdsk24tb.txt in an elevated command prompt. Took about 29 hours. The majority of the time was spent in Stage 5: Looking for bad, free clusters ... Will run other tests (SMART, etc.) when I get a chance. Has not been noticeably noisy so far. Will see how it sounds with more tests and when copying TBs of data to it. Have it placed on an old case fan on standoffs blowing up to provide air circulation, as I do with the easystores.

Easy to use and setup. Works great for a backup storage or RAID configuration for a media server. I personally use this for my 3D modeling projects. I model on both my Windows Desktop and Macbook Air. No problems with switching between devices, and it's compact, which I appreciate taking with me when traveling. It's pretty quiet considering it's a HDD inside. Do I wish it was a little quieter yeah but for price/TB it's hard to beat. Also I've had other branded hard drives before and they fail. I have yet to have a Seagate drive fail in ~20 years of owning them.

It works well. Only complaint wpuld be noise. I am building a chasis made mostly out of parachute cord to hold it and dampen the vibrations

I like the fact that the one I bought is 24 terabytes I also like the fact that it came with good instructions and that the capacity that it can handle It's good for the type of Things I do with music and With AI research Um This th what's needed

It's Great! I love it. It's Quiet, very spacious and I got it for a Heck of a Deal at Best Buy!

Grabbed the 24tb just to backup everything all in one. Had for over a month and it does the job.

Excellent for backups. Fast speeds using in my Ugreen NAS after shucking two drives no issues so far and its been 3 months so far.

These are reliable devices that i have been purchasing many times over the past few years and i have never experienced any negative situations with these as i have seen with other brands . So i would definitely recommend this

This is my best purchase so far. It's a good deal for 24 TB, and Seagate is one of the best Drives for PCs and storage. It's silent and makes no sound while loading. Most of my external drives have been Seagate for more than 10 years now—the best of the Best.

Very well product great problem solver for thoes who have so many drives and wants everything in on cental hub

I guess you get what you pay for. These Seagate drives are not sturdy. I own three of these drives: 8TB, 22TB and this 24TB. This one quit after one week, and after I spent days copying media to it. I used it as a Time Machine backup, so it has my personal data on it. It cannot be reformatted or erased by me or even the Geek Squad. So even though it's under warranty. I cannot return it to Seagate for fear of my data being stolen. Read the fine print, they even warn you that your data might get stolen if you don't erase a drive before returning it. It's now a $250 door stop. I will not buy another one. Very disappointed. And now my trust in the 8 TB & 22 TB drives has been undermined.

⭐️⭐️⭐️⭐️⭐️ Excellent value for high-capacity storage Picked this up in-store and it’s been exactly what I expected from Seagate. The 24TB capacity is massive, performance is solid for an external USB drive, and setup was completely plug-and-play. The enclosure feels sturdy, runs quietly, and stays reasonably cool even under sustained use. This is a great option for large media libraries, backups, or bulk storage without paying enterprise-drive prices. The included Rescue Data Recovery service is also a nice peace-of-mind bonus. Overall, outstanding value for the price — reliable, fast enough for its class, and doing exactly what it’s supposed to do. Would absolutely buy again.

Let's get this out of the way first: the drive works fine, speeds are OK, the noise level is more or less what you'd expect (although it is a little loud as it wakes up). The included power adapter even lets you swap in connectors for other regions if you're taking it outside the US. The reason I can't give it more stars - other than the fact that I've only had it for a few days - is because it feels like Seagate's throwing these together out of whatever parts they have on hand. Best Buy lists this model as connecting via a USB-C cable, but the one I recieved uses a microUSB 3.0 cable - you know, that weird double-wide microUSB that got used on a handful of Samsung phones in the years leading up to USB-C, a handful of external USB storage devices like these, and literally nowhere else. The product page on Seagate's website doesn't promise any sort of connector at all, just that it's USB 3.0, and I don't know if that means there are USB-C and microUSB versions floating around, or if Best Buy reasonably assumed anyone talking about USB 3.0 these days would just use USB-C. My guess is that most buyers don't typically have spare microUSB 3.0 cables lying around, either, whereas USB-C is pretty commonplace by now - try not to lose or break the cable that's included. The actual drive included in the enclosure is also a matter of chance. There are a lot of reports of these models containing enterprise-grade Exos X24 drives, but many recent purchasers - myself included - have found themselves receiving consumer-grade Barracuda HDDs instead. At the moment the quality of the drives is unknown compared to the Exos drives, as they're new enough that Seagate only added them to their website in the last few days, but they're certainly not designed for the sort of use and abuse an Exos drive is equipped to deal with. All that said, these are a good buy when there's a sale. At full price, it's another matter - only bite if you're comfortable getting saddled with a lower-grade drive.

This product is one of the best storage devices I have ever used. It is easy to get up and running right out of the box. The included instruction manual is easy to understand and gives detailed instructions on how to configure the unit to your specific setup, be it iOS or Windows. It very slim and takes up very little desk space. I use mostly iOS, and moving files over is as simple as clicking and dragging.

This is a good drive, very large capacity, when it is online it is fast to read and write, but LOUD... like OMG loud! I added padding underneath it and still loud. The other thing is that it takes much longer to warm up than other drives I have had, but that was understood as it is scanning a much larger drive than my last.

We have been using the Seagate USB expansions for a few years for archive storage of files, basically for long term storage, and this 24TB version is fantastic... more storage, means less drives! The drive connects fine USB2 and USB3, no issue. Excellent transfer speeds.

Great product at a great value!! Always reliable! Tons of storage. So easy to use!

Lots of space. Works well. Noisy on startup and initiak seeks. Suggestion: If not used frequently, connect only when needed.
