Summary: Upgrading from 250GB in my NAS drive to this was simple. Open the NAS box, pop this in and switch on. Thats all there is to it. Read lots of reviews criticising the drive because of "green" firmware, apparently drive fails due to power conservation protocols, i havent seen this yet, so am very happy. Speed is super quick, loads of space to fill.
Summary: My iMac had a 500gb WD Caviar 5000AAKS and as everyone knows it can be quite nerve racking trying to find a replacement drive that is fully compatible and at a good price point. This drive hit both on the nail and I am very happy with the performance. I have been using smcFancontrol to monitor the performance and it has been great.
Summary: and i can report that the drive is till going strong. I have found these drives to be very reliable on the whole. Before this I had two Seagate ST31000524AS 3.5 inch Barracuda drives. Both failed in just outside of a year. Thankfully I had a SMART utility running in the background that forewarned me before they failed so I was able to back up my vital info. I had alway thought Seagate drives were excellent quality, but this has changed my opinion.
Summary: Fitted this to a Topfield PVR in place of the 7200rpm WD Disk originally fitted. When I switched on I thought it was faulty but then I heard a slight click and the Topfield asked to format it. Putting my ear to it confirmed it was rotating. So now the humming noise of the previous disk is a thing of the past and I have a silent PVR with oodles of disk space.
Summary: I had reservations about purchasing this hdd mainly due to other reviewers saying they are noisy. Well this WD 1.5TB is smooth and quiet too. Having preferred other HDD manufacturers in the past I was unsure about buying from Western Digital, but after buying this one I would definitely buy thiers again. The slower spin speed is not a problem as it is installed in a NAS drive used only for storage.
Summary: Bought this drive as main drive in silent low energy self build. The computer is in the bedroom and is left on at night to download files when connection is best. All fans on the computer virtually silent so any noise from drive would be obvious. Reading and writing barely audible. Energy use according to reviews also seems low (one of the reasons I avoided faster drives).
Summary: Having had my hard drive die three years after purchasing my 24" intel iMac, I decided to fix it myself and bought this replacement drive after hunting around the net for recommendations. Installed it yesterday by following a video how-to on youtube and it fired up right away without any issues. I now have a lovely working Mac with 1.5TB of storage split into three partitions for my particular needs.
