Seagate 4TB portable HD
Using it to backup all my videos and photos, so far it hasn't missed a beat, it's replacing my other older smaller HDs and consolidating them onto one.

not as large
I was very surprised when I picked up my new hard drive. It was half the size and weight of the previous ones I've purchased. Much easier to store .

Q: Why does the Seagate 4TB Expansion Portable Hard Drive show less than 4TB on a computer?
A: Because storage makers rate 1TB as 1,000,000,000,000 bytes, while Windows and macOS report capacity differently. A 4TB drive will always show less usable space after formatting, so that difference is normal for this model.
Q: Does the Seagate 4TB Expansion Portable Hard Drive need a separate power adaptor?
A: No. This is a portable USB hard drive, so it is powered through the USB connection rather than a wall adaptor. That makes it easier to carry with a laptop, but performance still depends on the computer's USB port and cable connection.
Q: Is the Seagate 4TB Expansion Portable Hard Drive better for storage than a portable SSD?
A: Yes, if capacity matters more than speed. This 4TB Expansion drive suits backups, photo libraries and large file storage, but a portable SSD is usually faster for frequent transfers, app launches and heavier editing work.
Q: Can the Seagate 4TB Expansion Portable Hard Drive be used for editing video directly from the drive?
A: Yes, for lighter workflows and file access over USB 3.0, especially with large media files. For demanding 4K editing, multi-stream timelines or lots of random file access, a portable SSD will usually feel faster and more responsive.
Q: What lifespan can you typically expect from the Seagate 4TB Expansion Portable Hard Drive?
A: A portable HDD like this is commonly expected to last around 3 to 5 years with normal use, although actual life varies by handling, heat and how often it is moved while running. It is best used as storage or backup, not as the only copy of important files.
