2 out of 5 eggsFailed when used with a TabloTV

Pros: Inexpensive for a 2TB USB drive

Cons: I tried to use this for video storage with a TabloTV. Initially it worked OK. The Tablo detected the drive and formatted. But after scheduling several back to back recordings all the recordings failed.

Other Thoughts: I suspect some sort of power-saving spin down mode. But that is only a guess on my part. A Seagate backup plus works fine with the Tablo.

1 out of 5 eggsAvoid!!!

Pros: Good price on a 2TB drive. Clean case. USB 3.0.

Cons: The USB cable doesn't seat securely in the drive. You go to plug in the cable and it doesn't click into place, or snap, or feel secure at all. The USB connector on the USB cable is longer than the slot to plug the cable into on the drive.

Transfer speeds, write, started at 70MB/s, which is very good. But then dropped to 10MB/s when I let go of the cable because it worked itself loose. I had to hold it back in.

The included USB cable is very short (9inches maybe?) and very stiff.

Other Thoughts: Seems like a good enclosure with a good drive for a good price. But they messed up on the USB 3.0 connection; which is one of those things where if it's not right it ruins the entire product. Gonna have to return these, bought 2 for work. Guess we gotta spend some more on WD or Seagate or Toshiba even.

5 out of 5 eggsAwesome, fast drive

Pros: This drive is perfect and I got it for $90 during a black friday/cyber monday sale. It is perfect for me and it runs great. Nice and small, and portable.

Cons: My only complaint is that I wish the cable that came with it was a bit larger. That's not really much of a problem though.

Other Thoughts: If you are looking for a fast, small, and portable external hard drive, this is the one for you.

5 out of 5 eggsFAST!

Pros: * Compact
* USB 3.0
* Powered by USB
* Very high capacity for a portable
* Much faster than I expected
* Price (I paid $100)
* Seems sturdy
* Water resistant
* Preformatted (NTFS)

Cons: * Not 7200rpm, but I knew that going in. (I don't think a single USB3.0 port can provide the power necessary for a 2TB 7200rpm drive)
* USB cable could be longer..

Other Thoughts: The biggest downside to USB-powered external hard drives has always been performance. Doing a full "user directory" backup would take hours.
They are slow. Painfully slow. Especially with small files.

This Adata 2TB USB 3.0 drive behaves like an externally-powered drive.
I was expecting transfer rates of no more than 45MB/s, so I was very surprised to see sustained transfer rates over 75MB/s.

Here are some stats:
97MB/s minimum = Transferring a single 4GB video file.
75MB/s sustained = Transferring 1.5TB of video files. (sizes ranging from 350MB to 8GB).
45MB/s sustained = Transferring 36GB of MP3's.

I highly recommend it.

5 out of 5 eggsReliable

Pros: This unit is small, fast and reliable and is all that you can expect from a 2TB USB 3.0 drive.

Cons: None.

Other Thoughts: After having bought several ADATA products in the past 2 years, that including an SSD drive, I can't go back to other brands, ever.
