Seagate 3TB external slim drive

I am very satisfied with this drive. I am a big believer in Seagate drives. All the drives in my pcs are Seagate and I also have 9 portable Seagate drives and have never had a problem with any of them.

3 TB expansion drive

Good little drive. Needs only a USB connection to your computer. Not large enough for backup storage for your whole system but handy for moving smaller numbers of files.

  • from Calgary, AB

It's working

Good, cheap (when on sale), reliable

  • from Edmonton, AB

Great addition for my laptop bag.

This little guy is a USB stick on steroids. No more worries (at less for now) with 3 TB of memory available. It's lite and compact and a fast data transfer speed. No heat or noise as it seamlessly transferred 80 gigs of files. 5 stars.

  • from Repentigny, QC

Nice buy!

Very compact. Plug and play. So good so far. Good price!!

  • from Toronto, ON

So far so good

Bought this as a hard drive expansion for my PS4. Plugged it in and it worked right away. No noticeable speed difference between the internal hard drive and this one, everything loads nice and speedy. Great purchase, especially on sale.

  • from Vancouver, BC

Nice and compact

Compact. Had to do a little configuring for it to work with my (older model) Mac Mini.

  • from Brantford, ON

Bought it from best buy on sale. Arrived within 3 days as promised. Easy to install, does as advertised, compact. No complaints. Would recommend.

Easy to Use Hard Drive

I picked up this hard drive during a Boxing Day sale. Great price on it, and it is very easy to use! You just plug it in and it sets itself up, then you just drag and drop what you want into the device. Easy! Highly recommended!
