1 out of 5 eggsDisappointed

Pros: Was nice until the drive started getting around 80% full.

Cons: Using this as a movie server drive for personal movies and documentaries that I make and share but as soon as it started getting around 80% full many of the movies would randomly turn into folders and were no longer recognized by the PC or media player as a movie file. Thinking it was a glitch I've removed the corrupt files/folders but now more keep showing up. its as if the drive will not accept more files.

Removed drive from case because it shows up as a

Make sure you don't keep valuables on this drive.

Other Thoughts: I do have this device connected through a Cisco router and add/remove file from it over the network. I've really only added files until they started getting corrupted.

Connecting drive directly to the PC and running an error check does not resolve the issue.

Seagate has no troubleshooting help / forum regarding this on their site. Multiple attempts to try and get help has failed.

Thankfully I always backup to the cloud but people on a budget would lose their data.

Looking back, I've had more problems with Seagate than any other brand, might be a coincidence.

I'll update if I can find a fix or Seagate ever calls back.

5 out of 5 eggsImpressed

Pros: Fast, light weight, reliable. Best way to describe this drive. Being a dual compatible OS device makes life a lot eaier when using both systems. Never have had any troubles with Seagate products and doubt I ever will. Great Job.

Cons: None to note for now.

5 out of 5 eggsSo far so... amazing

Pros: Speed, size, weight, convenience, design.

Cons: It doesn't have the FireWire option like the Seagate GoFlex have. But who needs that these days?

Other Thoughts: Peak speed when writing to disk was 150 mb/s. Average speed is 100 mb/s when plugged with USB 3.0. I am really impressed by the value of this hard drive. This is why I always buy Seagate.

5 out of 5 eggsWOW

Pros: VERY fast backup - 500 gigs in less than 1 hour using the USB3.0 port.
Powered from the laptop using two USB ports with the included cord.

Cons: None found so far.

Other Thoughts: I bought two of these to swap out weekly for off site storage. One is on continuously until swapped out the next week. Very fast downloads. I have not hooked up to cloud access or mobile backup yet.

5 out of 5 eggsUn excellent produit !

Pros: Wow ! Fast ( ...120, 140 MB/s on write ) compact and amazing finish. Seagate send it with 2 USB cables : 1 with 1to1 and another 1to2 ( Y ) to help if your USB port on your computer hasent enough power on it. A little default is a lack of tab under the drive. However, you can stick somme rubber tape to avoid the slip of the HD.

Cons: Un HD compact, rapide et d'une qualité ( à simplement le prendre dans votre main, vous comprendrez ) exceptionnelle. Capacité de stockage et vitesse de lecture écriture sont au rendez-vous. Il maque cependant de petite patte au disque, ce qui lui éviterait de glisser sur les surface dures. Toutefois, j'ai contourner le problème on collant quatre petits morceaux de tape caoutchouc en dessous.

Other Thoughts: Vous ne regretterez pas cet achat / Do not hesitate. That's the drive you'll always waiting for.

5 out of 5 eggsSuper Fast for sure

Pros: I have the Western Digital 2TB drives and I ran a test on these drives empty and transferring a big (18gb) file averaged about 110Mb for the WD's and around 210Mb for the Seagate's. Almost 2x the speed and 2x the size. Love it.

Cons: None so far, a bit bigger but what can you expect for a 4TB (3.6 usable) drive.
