Pros: Firmware features that benefit use in a NAS or RAID setup. The unit has only been deployed for about 2 months as of today with no issues. Will update in the future if any issues arise prematurely.
Cons: Rated at 1/1x10^14 URE so this is not an enterprise grade drive (e.g. 1/1x10^16 URE adds a price premium). Keep this in mind if you are using this drive for storage of critical data and plan for drive failure accordingly.
Summary: Hope drive prices come down. I'd love to get some 8TB disks for my arrays.
Pros: I have five of these running now as members of two different arrays. They work great. Sometimes they can get a little hot, like during a parity check operation where the disk is seeking for 24-36 hours straight. Speed is good for RAID, and have been reliable for me so far.
Cons: Could be cheaper, WD charges a premium for the fancy red label (I have a bunch of WD Greens running in arrays too that work just as well)
Excerpt: Using this drive in a Readynas duo v1; it synced safely and seems to run cooler than the Seagate that it replaced. Western Digital Red is not listed as a compatible hard disk for the Duo v1 on Netgear's site but searching the netgear forums show good success with these drives.
Summary: I bought 3 drives and put each one at a time in my unRAID NAS and ran a pre-clear script to write all zeros and then read the SMART. All 3 passed, had perfect SMART values and no pre-existing conditions. I think these drives will last a long time.
Summary: All drives have over 4000 hours on them now and smartctl reports no problems whatsoever. In my experience if a drive does not die first week and shows no errors it is going to last.
Pros: I built a RAIDZ2 on four drives. After a week I turned off the fan in front of drives, these drives run so cool there was no need for it. Without fan they stay below 40 °C. Write performance is more than satisfactory for a storage, when copying files over gigabit ethernet network there is no I/O ...
