We needed a place to store our movie collection and these fit the bill. We set up a NAS program with these and they work well. Very pleased.

This is not your average Western Digital desktop hard drive. The WD Reds are made for heavy duty, high duty cycle use. They are made for use in Network Attached Storage devices. The NAS environment can really torture a hard drive. Especially when it has to support a lot of users and devices. This hard drive is made to be able to function in such an environment.I have a Terramaster NAS in my home network. That system has two Seagate Ironwolf hard drives. It has been flawless in operation. I attached an external hard drive enclosure to the Terramaster to have a backup of all the data. The hard drive enclosure does not come with its own hard drive. You get to choose, depending on your needs. I bought this WD Red hard drive to use as the backup for the Terramaster. I backup the data from the NAS on this hard drive and then store the drive in a safe location.The WD Red has been flawless. It is easily the equivalent of the Seagate Ironwolf. The operation is silent and reliable. I have not had any issues with these NAS hard drives. Yes you can use a regular desktop hard drive for this purpose. A WD Blue caviar hard drive will also work. However, the WD Red is a more robust hard drive. It is more expensive than a regular desktop hard drive. But the reliability and peace of mind are worth it.NAS hard drives will also work on your desktop computer. You can swap out your WD Blue hard drive for this one. You will get added durability and dependability. But it will only be worth the extra cost if your computer is regularly stressed. A one-user desktop PC that gets used for 5 hours per day is not under stress. However, if you have a PC that is used for security monitoring purposes or as a home server, then yes, invest in a more robust hard drive.I love solid state hard drives for their performance and lighter weight when used on a laptop. However, for storage purposes, I still prefer a mechanical hard drive. If I were building my own desktop PC, yes, I would use a NAS hard drive such as the WD Red. But I would not throw out a working WD Blue that comes with a new PC. Evaluate your needs carefully.A data storage system used in a business setting should have robust hard drives. If you are a content creator on Youtube, get at least a four bay NAS storage device and fill those drive bays with WD Reds or Seagate Ironwolves. If you surf the internet, shop online, and basically only consume social media, then a regular PC with a traditional desktop hard drive will be good enough.Highly recommended for NAS Storage systems and heavy-duty desktop use.
