Summary: I installed (2) of the 3TB units into a WirePath 16 CH DVR and they are both working perfectly. Recorded picture and playback appears to have improved, but can't say 100% for sure. It does search and find items faster, and took less than 15 minutes. I could not be happier!
Summary: Don't ever buy any Seagate hard drives. I had 4 fail on me in succession. Their drive quality has dropped over the years and are now no longer the brand that they used to be. All 4 failed drives are less than a year old. They all developed the click of death.
Summary: I purchased two of these in December 2012 and they both have been generally in continuous power on mode since. I use these drives in my NAS array and generally have no complaints, except that one of them just died and it's been only 18 months since purchase.
Excerpt: I used these drives in a QNAP 4-drive NAS for recording video 24x7 from 25 surveillance cameras. In 2 years we've had to replace 4 drives due to failures. Two of the drives failed within the first year, and 1 of the replacements has already failed.
A dud - don't waste your hard earned money on these drives

Summary: Pros - none Cons - After purchasing 2 of these drives in February I've yet to receive even 1 that is actually works and is new. I've had the drives already replaced 3 times, with most of them being DOA.
Summary: In spite of an ice storm in the region, the product arrived from Amazon in a timely manner. After three weeks of 24/7 use, the drive shows all signs of fine performance and plenty of storage at an affordable price.
Summary: I'm using this for a Q-See QT548. This is a definite upgrade from the WD 500 "green" drive that comes standard. I could tell right away, after recording for a little while, that the performance was greatly improved.
