Pulled apart and took the drive out, works well in my NAS, was a 2.5" drive inside and working perfectly. This would have voided my warranty, but you can't buy internal 2.5" drives of this size anywhere.

Excellent! Used as an external for a PS4, works like a dream, just as fast as the machine's internal HDD. Excellent! Used as an external for a PS4, works like a dream, just as fast as the machine's internal HDD.

I have bought a number of these for back ups and transporting very large files. They have never let me down. If you want something more stable, try an SSD drive but much higher price. If you don't throw these around or drop them then they will do you just fine. I have bought a number of these for back ups and transporting very large files. They have never let me down.

I was suprised at just how small the portable storage was. It isn't even bigger than my hand. A lot of space as expected but you shouldn't expect a whole 4TB. My Seagate 4TB drive reads as only having 3.63TB. For a HDD it's pretty fast too. I was suprised at just how small the portable storage was. It isn't even bigger than my hand.

Work as it should. Will definitely come back for another one of this. Work as it should. Will definitely come back for another one of this.

I've always found Seagate External HDD to be fit for purpose. This drive is that. And 4TB is the size I need. I've always found Seagate External HDD to be fit for purpose. This drive is that. And 4TB is the size I need.

Worth the value for the product - an excellent product works well. Worth the value for the product - an excellent product works well.

It does what it says on the box. I formatted to Mac OS Extended and it works as expected with my 2 Macbook Pro and Mac Mini. It does what it says on the box. I formatted to Mac OS Extended and it works as expected with my 2 Macbook Pro and Mac Mini.

Really enjoying my new external harddrive. Has taken a lot of pressure off running programs on my laptop with a lot more space. Runs smoothly and no issues thus far!

As advertised, good product. Excellent value. As advertised, good product. Excellent value.

Simple installation, use it as a external hard drive for my PS4 and probably will use for something else when I move to PS5 or pc. Works great. Simple installation, use it as a external hard drive for my PS4 and probably will use for something else when I move to PS5 or pc. Works great.

This is a very easy to use back up for all your data - it is quite literally 'plug and play.' I have backed up 60 years of photos in the touch of a button. Highly recommended.
