Working, but beware of bad sectors; always keep backups!
By Milos Ivanovic
I received this drive 8 months ago and it is still working in an acceptable manner by my standards. For more details, please continue reading.
Having recently re-browsed the Amazon reviews for this product, I saw some people complaining that their drive had failed after x months having ordered it around the same time as me. This prompted me to fully check my drive's health so that I could at least be reassured that it is in full working order for the time being. I ran a read test on Windows using HD Tune Pro since that's where my drive was plugged in at the time, and the results (shown in as screenshots attached to this review) show the drive did in fact contain some bad sectors.
I ran a non-destructive write test using badblocks on Linux which, for each sector, will first read the sector and store it in memory, then write a random pattern, then read this pattern back and make sure it matches the pattern that was written, and finally restore the original contents of the sector. I had backups just in case, so I wasn't worried and was mainly doing this for science.
At the end, SMART output showed 2310 bad sectors existed on the drive. Since I waited 8 months to run this test and used the drive sparingly, it's unclear whether the sectors were always bad or if they developed over time. It also just so happens that none of the data I had stored on the drive were on these bad sectors. Despite the clear indication of potential failure, all sectors were restored to full working order after being written over. This means the sectors were really just held a weak magnetic charge, and were not permanently bad from e.g. physical damage to the platter.
As a result, the pending/offline uncorrectable sector counts were dropped to 0 and the reallocated sector count did not increase at all. If interested, I've included the entire SMART output below.

You can see there is an error count, but no pending/uncorrectable or reallocated sectors. Although it's clear that the drive is currently working, the history of weak sectors means I will keep a close eye on it in case data ends up being written to the sectors that used to be weak, since if they become weak again, the drive will have trouble reading from them and I could start to lose data as a result.
Remember: all drives fail, no matter what make or model you buy, so always keep backups and be prepared for the inevitable.

Died during backup after less than 2 hours.
By Amazon Addict
I was pleased to initially get this backup HDD, it is small, portable, clean design, with a nice black color. It was packed in an easy to open and protective box and the basic instructions were simple and clear, plug the HDD into your computer with the accompanying cord and download the Seagate Dashboard application to begin backing up. I did just that, and initially seemed to be up to a great start. The Dashboard app isn't fancy, but appeared to be sufficient to get the job done.
However, fast forward about 2 hours to ~80% backed up, and the HDD starts to occasionally beep. I was not aware the drive had any speakers so inititally I figured I had heard something outside my house. Gradually over the next 10 minutes the beeping became more and more frequent until it was obvious they were coming from the drive and were coming out about every second. I also noticed at this point the drive was no longer backing up. Thinking something was amiss, I unplugged the drive, restarted the Dashboard, and reconnected the drive. No luck, the drive was now not being recognized by my computer, either through the file system, the Device Manager, the Drive Manager, or Seagate's Dashboard application. It still made the beeping sound. I repeated this process several times, tried different ports, a different computer, a different cable, nothing worked.
Seagate tech support is totally unhelpful. I seemed to only get form emails from them. Most would not even respond to entire parts of my email, basically telling me to troubleshoot by trying different computer, restarting, etc. I found it really disheartening that a company's harddrive would fail only part of the way through it's first use. Thankfully Amazon has a fantastic return program! I would not buy from Seagate again.

very fast drive with huge 4TB capacity
This review is for the 4TB "Fast" RAID 0 version of the 4TB drive. As of this time, the Seagate "Fast" RAID 0 version only comes in the 4TB size.
This Seagate drive is a phenomenal backup drive. It really is FAST! It's so fast because internally it's composed of two hard drives running in parallel in a RAID 0 configuration to give twice the throughput.
It comes formatted in NTFS. Mac users who want to keep using it with NTFS will need to go to Seagate's website to download an NTFS-for-Mac program by Paragon to be able to write to this drive. It's a free program on the Seagate site. Alternatively, Mac users could format the drive to Mac's native "Mac OS Extended (Journaled)" file format (also known as HFS+ format). If you want to share this HFS+ formatted drive with a PC, you can install Paragon's HFS-for-Win program on your PC to enable read/write capability on Mac drives. This HFS-for-Win program is also available for free on the Seagate support site.
There are definite advantages of NTFS over HFS+. NTFS gives essentially the same sequential read/write speeds as HFS+, but where NTFS shines is it gives MUCH HIGHER random read/write speeds than HFS+.
Here are typical benchmark numbers on my Macbook Air using DiskMark with this drive. Numbers are in MB per second:
NTFS: 260 (seq. read), 217 (seq. write), 32 (random read), 12 (random write)
HFS+: 253 (seq. read), 214 (seq. write), 20 (random read), 0.5 (random write)
Make sure you plug it into a USB 3.0 port that can provide sufficient power to spin the two physical disks. A sign that it is not getting enough power is the arms making noticeable noise when the drive reads. If that happens you will either have to plug it into a powered USB 3.0 hub or use the USB 3.0 Y cable. I have mine plugged into a powered USB 3.0 hub and it runs totally silently.
The most significant potential negative is the RAID 0 configuration. Basically, because it's composed of two parallel physical drives acting as one, if either drive malfunctions, the total two-drive combo will be toast. In other words, this drive statistically is twice as likely to fail as a similar Seagate drive that is composed of only one physical drive. Of course, that's the trade-off one makes when purchasing this drive: trading reliability and cost for double the speed.
