Fantastic drives

Threw four of these into a DS1517+ Raid 10 for photo storage. My other NAS has 6 4TB WD Red drives and hasn't had a problem in 4 years. I expect these14TB drives will run without issue for at least double their 5 year warranty as other WD drives have.

Great Product

I purchased this drive for my home network attached storage device. I installed this in a Unifi UNAS-2 powered by POE. Works great!

Install went well, no problems.

Product was received and installed as advertised. No problems. This was an upgrade to the MyCloudEX2Ultra from two 6 TB to the two 14 TB drives. Installed them in the unit, formatted the drives. Then installed at customer site. Did backup of systems images as well as setup File History. Worked well.
