You can't beat the WD RED drives for your NAS or network attached storage. I have three of these and a 4tb now in a Netgear nas box for my storage needs. Never has there been a hiccup from these drives. I know I have had these over a year or more now. Maybe the date I bought these are showing in this review, I'm not sure at the moment. These drives are designed for NAS storage. I will buy more. I've had past problems with Seagate so I'm sorry, I won't touch those. WD reviews elsewhere will show you how long these last. Try backblaze.com and look through their blog. They have a chart for the failure rates of all the different drives they have used in their storage system.

I have purchased these drives I believe 2 year ago, I am finally just getting around to reviewing it. So far these drives have done well. I have this in my Qnap which has had multiple power interruptions and all 4 drives are still running strong with no uncorrectable errors.

One thing though, I did get this as opposed to the Hitachi brand because they say it's quieter, however if it's in the bedroom, it's not the quietest thing, you can still hear a lot of the read and writes.

These are great drives, no issues so far!

Excellent Drives. I've been running a variety of WD Red, Green, and Seagate Archive Drives for the better part of several years, and I thought that I would share some useful advice for things to watch out for when buying new drives, and detecting infant mortality.

First thing to look for is to observe the packaging the drive arrives in. It is industry practice to ship one or more drives in boxes that are made to perfectly fit the drive. Inside the box, the drive should be suspended with two plastic holders. These holders suspend the drive and dampen any drops the package may experience during transit. (Bulk orders (15+) may be shipped in a single larger box with foam cut-out arrays).

Secondly, when installing the drives, make sure that your hands are clean. Give them a wash, or better yet, wear gloves. Avoid transferring finger/hand oil to the drives so that hot-spots aren't created.

Thirdly, once the drives are installed, give them a full, long format. You can run 1, 3, 5, (or even more) passes on the disks. This ensures that every single sector of the drives gets written to. Once the format is complete, look up the SMART data, and check the values for anything alarming. If a drive suffered damage in shipping, now is when it may be noticeable. Compare the values to your other drives. Start-up times, head parks and so fourth may vary slightly so there's nothing to be worried about a little deviation there, but pay attention to failed reads, reallocated sectors, and RUEs.

Granted, all of this advice should be taken with a grain of salt since SMART values are not the silver bullet to predict drive failure, but this testing should be a good indicator on whether or not a drive is ready for production use.

Above all else, remember that backups are your friend.

I installed the 6TB WD Red drive in replacement for a failed 2TB non-WD drive. No real complaints, the old drive had been in a Synology server since 2012. All drives fail eventually but according to the data published by Backblaze, a server company with over 41,000 drives spinning, WD drives deliver the best reliability/cost performance.
The WD 6TB drive was installed in a RAID-5 array and has been in operation for a month with no problems what soever. The health data looks good. I will gradually replace the 2TB drives that have been in service for four years now with 6TB drives to expand the server's capacity. 6TB of capacity seemed adequate four years ago but photo files have gotten a -lot- larger and I've been shooting more...
Reliability, not losing my photographs, is -very- important to me and my confidence in WD drives is high based on the performance in another of my servers.

I ordered five to use as new internal drives in our old Synology DS1513+ NAS. Unfortunately, two of the five drives arrived D.O.A. (not recognizable by the NAS). At first, I thought the NAS was malfunctioning, but I pulled out all five drives and tested them in a USB doc attached to my Mac...and two would not even spin up. I was able to get the NAS up and running on a 3-disk RAID-5 on Saturday, and while the volume was building, I logged into Amazon to RMA the two dead drives and request replacements. The replacements arrived on Sunday afternoon (the very next day), so I added them to the NAS and expanded the volume. All is working perfectly. I'm seeing throughput on the NAS of around 120 MB/s with peaks above 200 MB/s. IOPs are north of 1,000 per volume. If these drives last 3+ years, I'll be very satisfied.
