WD Red drives are my go-to standard for when I need a drive for a NAS setup. I use these with FreeNAS with great success. Internal in an average system, I get gt;100MBps using rsync from one array to another.

Bought these for my Windows 10 Desktop / Streaming Server (PLEX). Just plugged them in and used Windows to create a storage space. Very easy , no hassle. Most time consuming thing was the physical install. Drive speeds are as listed, no loud noises (3 drives) , packaging was top notch as well.

I have two Netgear NAS systems and they were populated with 2TB WD "Green" drives which performed well enough. Once I needed to expand the required space I decided to try the 4TB "Red" drives (the NAS systems can't handle the 6Tb ones :( ) and it was a good choice.

I haven't seen any issues with them yet. Just some warnings of the Pending Sector count in the SMART readings for one disk. (Likely due to sudden power outages) Highly recommend buying this brand.

I have four of these HDDs running and have had two of them running 24/7 for almost three years

The seller listed the product as a pack of 20, but shipped a quantity of one. That said they agreed to issue a full refund as well as a return shipping label and issued a gift certificate for the inconvenience.

drives have been running great, I have 4 in a RAID 5 setup and they are running quietly with no issues on SMART tests. Transfer rate of approx. 450MB/s in Raid 5 read test which works perfect for my home NAS server

Not working / corrupted and returned the disk to WD for replacement. Packing was not sufficient and loose packing.

Ordered 2x 4TB Drives. Despite telephone and email confirmation (prior to order) that these hard drives are sold in Western Digital RETAIL packaging.... they are NOT. Received in folded cardboard with layer of protective foam - inside a jiffy bag (which had split along the seam half way).

The performance of the 4TB is a very good enough on most counts for a network storage drive. The performance of the Red Series so far remains consistent. Even if you look at average access tests, not only it performs better than Seagate' 4TB NAS counterpart but also the WD Red 2 and 3TB variants.

I bought 2 of these to extend my NAS. Plug them in, fire it up, doing a backup in 10 minutes. Lifespan??? I've only had these spinning for a couple of weeks now, but the pair of WD Red 3TB already in there have been spinning for a year with no errors, and I don't expect these to have issues either.
