Rated 4 out of 5 by from Good value storage. I usually buy Seagate drives, but as I was after a 3TB unit this time and knowing the Seagate 3TB drives have suffered with failure rates, I went for a WD Blue. I was really surprised at how quiet it is. My system is very quiet and I can hear the bearing whirr of the SG 2TB already in there, this WD is silent. Would reccomend.

Rated 4 out of 5 by from Good value but over aggressive power management for 24/7 use Good value, but over aggressive power management for 24/7 use. Nice and quite drive, reasonable transfer speeds for a 5400rpm drive. Runs pretty cool too, 26deg in my case. But. If you have this drive on continually, this drive will eat it's way through its rated 300,000 load unload cycles in under 2 years, because, as you will hear, "click" every 8-30 seconds "click" it will unload the head due to the aggressive power management western digital applied to this range. These are desktop drives and do not need such aggressive head parking. Every couple of minutes would suffice, it's not like desktop users are worried about battery power. This is just unnecessary wear and tear on the drive. My load unload count is 4688 after 192 hours. At this rate, in 520 days my drive will be out of warranty due to being over the 300000 mark, as stated in western digitals warranty policy. That is not even 2 years, which is the warranty length of the drive. 4688/192 = 24 per hour. 300000/24 = 520 days. CONCLUSION: If you intend on using your disks for 24/7 operation choose the slighly more costly RED edition which designed for 24/7 use and have a less aggressive power saving schema. If you turn your PC on/off all the time then you won't need to worry about this. It's a shame WD have opted for this level of power saving on a desktop drive, hence I rated the drive 3 (average) for quality based on what is essentially a "firmware" issue that can adversely affect the disks "percieved life" and warranty status under continuous operating conditions. This doesn't mean the drive will fail at 300k load unload cycles, it just means if you do hit this mark before your warranty has expired, technically your drive will be considered past its warranted "wear and tear" value for head parking, at no fault of your own.
