5 out of 5 eggsSeagate Backup Plus Fast 4TB

Pros: The Seagate Backup Plus Fast 4TB is an absolutely terrific external portable Hard Drive. Having 2 2TB Hard Drives in Raid-0 has to be the best idea ever for an external portable Hard drive, I was so excited upon receiving The Seagate Backup Plus Fast, this is a truly innovative product. I am going to keep this review somewhat short, The Seagate Backup Plus Fast is very solid and is well constructed and feels of great quality. It contains 2, SAMSUNG Spinpoint M9T ST2000LM003 2TB 5400 RPM 32MB Cache SATA 6.0Gb/s 2.5" with an "Average Seek Time of 12ms" and an "Average Latency of 5.6ms", and all the Reviews I have read regarding these Drives have been terrific, I do not think I seen one bad review.

Cons: I can honestly not think of one bad thing to say about The Seagate Backup Plus Fast 4TB, I think it is a terrific , innovative design and I truly love this product.

Other Thoughts: I did a few tests with The Seagate Backup Plus Fast 4TB, 1st with ATTO Disk Benchmark I received a steady 200 MB/s both Read and Write, and with AIDA64 Disk Benchmark Read Test Suite I received a max transfer speed of 210.9 MB/s and an Average Read Access of 0.00ms! and I was completely enthralled with these results. The price point of The Seagate Backup Plus Fast 4TB is awesome, it is actually cheaper to buy the Backup Plus Fast than to buy the Drives themselves and I think you would have trouble finding a Raid-0 to USB3 adapter, and if so, how much would that cost you. Like I mentioned before this is a terrific and innovative product at a great price point, and you will be very satisfied with The Seagate Backup Plus Fast 4TB.

5 out of 5 eggsFast & Portable

Pros: Nice aluminum case with a small white LED to tell you it's on. The software that is bundled is nice and lets you back up as you go or set a defined time frame for your back ups. You can also just drag and drop your own files as well.

Cons: None

Other Thoughts: I am using this as back ups of my photography. With USB 3.0 and 4TB of storage this should last me a long time.

4 out of 5 eggsNecessary Backup

Pros: - Small Size
- No power brick needed
- Preloaded software has no Bloat ware
- Large Capacity
- Intelligent Run cycle for back
- Fast back up for Mechanical HDD's
- Lots of instructions in many languages.
- Can be converted to regular Mechanical drive if you have the knowledge of computer building

Cons: - None at present

Other Thoughts: Seagate was once THE only Hard disk to buy, their quality was second to NONE. They were the best, hands down. Then Businessmen and accountants started to run the company and the quality dropped terribly as they started eating up other vulnerable and other un reliable companies. Its my opinion that they have learned from their mistakes in the past and their hdd are getting slowly better quality but still not to the Rock Solid standard of the glory years of Seagate.
My first thought was this hard drive cannot breath. Its totally incased inside this plastic prison.
This is not a bad thing as I have noticed that the drive stays in a state of sleep until you activate it for back up and spilling coffee will not kill the drive.
The Speed was 9 minutes for 350GB from my SSD Very fast but my SSD is fast and my X99 with DDR4 is fast too and I used USB 3.0 which is faster than SATA 3. Alas, you are only as fast as your slowest part in computing. That would be this HARD DRIVE in this circumstance. I would recommend this for a primary back up but I would also recommend having an even bigger archive drive array to supplement this one small tool. This is a good product but even the best can break down at some time or other so never put all your eggs in one basket. Put them in several places so your backups are kept for many years to come.

4 out of 5 eggsSo far so good

Pros: Cheapest per Gb costs i've seen for a whiles.

Cons: Way cheaper elsewhere.
Only 2 year warranty :(

Other Thoughts: Some older pc's will not see the whole drive, or the drive at all, so you XP users may have problems - on newer win OS'es i've had no problem (with newer BIOSes for their hardware)
It works under latest Ubuntu desktop OS just fine from my dell vostor laptop!

3 out of 5 eggsNeeds more energy

Pros: Advantage: 4TB and faster

Cons: Disadvantage: More expensive per GB, double size and double weight of a 2TB. Needs more energy, sometimes two cables needs to be used in order to provide energy.

Other Thoughts: The reason giving 3 eggs it's because the price benefit.
For most users this hard drive only will be worth to buy when the price per GB will be cheaper than 2TB.
On Newegg sometimes it's possible to buy for $90 a 2TB HD

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.
