Seagate's 28TB Expansion portable HDD drops to $329 — Massive storage for your desktop
Boost your backup storage options

Check out this great deal on one of the largest external HDDs on the market. Data backup enthusiasts rejoice — if you need a high-capacity storage option for your desktop, this large 28TB drive has plenty of space for you to store your pictures and videos, as well as a massive amount of any other data types. The Seagate Expansion drive is a large traditional hard disk drive contained in an external enclosure that requires its own power source. These external storage solutions are fantastic for storing data that doesn't require superfast transfer rates and are a convenient solution if you don't want to go down the NAS route. Some of these external HDD enclosures are good for shucking the drives out of, but do some research into what drives they contain, as shucking the drive will most certainly void the warranty.
You can save $60 on the list price of the Seagate Expansion Desktop 28TB HDD, now only $329 at Best Buy. The massive 28TB capacity means more room for your files, and with the USB 3.0 bandwidth, the transfer speeds will be fast enough for most storage and backup situations.
The 28TB Seagate Expansion HHD is housed in a rugged black plastic case that measures 7x2x5 inches with small feet on the bottom of the chassis. Power and USB cable connections are located at the rear of the drive, and this is where you will need to connect the external AC power adapter. Make sure you have ample power outlets available for connecting this device alongside your desktop PC or laptop.
Seagate Expansion Desktop 28TB HDD: now $329 at Best Buy (was $389)
This discount is for the 28TB edition, but the Seagate Expansion Desktop HDD also comes in other capacities, ranging from 8TB to this 28TB model. The drive requires both a USB cable to connect to your computer and a power cable to operate.
The Seagate Expansion Desktop 28TB HDD comes with an 18-inch USB 3.0 cable and a power cable included in the box. Accompanying the purchase of the Seagate drive is the option of using Seagate's Rescue Data Recovery Services software for data backups should the drive fail and you need to recover your precious data.

Pemalite Why do we need ample power outlets? Is it using more than 1? Odd statement to have in an article.Reply
Either way, this is a Seagate, I don't like gambling with my data if I can help it... -

They are simply pointing out you will need 1 ac outlet for each drive.
Having said that, if you need multiple 28 terabyte external drives, you have bigger problems than power! -
SomeoneElse23 A Seagate in an external enclosure seems to be asking for trouble?Reply
That's a lot of money and a lot of space... for a one year warranty! I'm really surprised TH is even talking about it.
Stay far, far away. -

This is using a 3.5" drive, which typically come with higher power requirements. I.E. External AC.derekullo said:I've got 2.5 inch 5 terabyte external drives that pull all the power they need from USB.

It's an expectation that it requires a power plug. -

The other user appeared to only be aware of drives that did not require external power. -
das_stig 28TB on s ingle HDD, with Seagate dubious quality and a couple years of warranty, no thanks.Reply
If you have that much data to backup, you need a professional solution.
Even some personal cloud storage are coming in at reasonable prices when you spread the cost and reliability.
