Pros
Excellent drives. I bought 4 of them.

Cons
A little pricy still but worth the money

Summary

Excellent drive plugged in to my qnap TD-459 pro+ and worked flawlessly. I just hope they last as the 5 year old 2TB green drives they replaced. All in all a great drive

Pros
It's working as it's supposed to.

Cons
Pricey for a drive that is, performance-wise, quite similar to the Green.

Summary

Drive works fine in a Synology NAS. Quite well suited to a NAS as it doesn't generate excessive heat.

Pros
Large capacity, silent operation, WD NAS quality

Cons
Aren't 6gb lol

Summary

Not much to say, capacity is great and silent operation, I have these and a pair of 3tb models running in nas boxes 24/7 and feel confident in them, speed is what it should be for this class of drive, just wishing they would go 6tb.

By: Steve_L8 2014-07-08 21:41

Pros
4tb. enough said

Cons
still a bit too costly

Summary

very wary of large capacity drives. i've had several 3tb drives fail on me after less than a year so i'm hoping this one will last a bit longer. so far it seems to be alright but only time will tell.

By: Alexandre_H 2014-05-24 14:00

Pros
Good transfert speed.

Cons
Cheap to buy.

Summary

I have 14 of those drives and so far they're working perfectly. Would recommend over those crappy Green Drive.
