Choosing a hard drive for your network attached storage (NAS) is about more than affordability. You need to consider other factors including capacity, vibration protection, and reliability.
Not all drives are the same
It's possible to purchase a desktop hard drive, throw it into your Network Attached Storage box and call it a day. This is OK if you're only going to install a single drive that won't be accessed by multiple users simultaneously. These more affordable drives don't have vibration protection and as such shouldn't be used in a multi-drive RAID setup where more than one motor running will cause vibration. That could have a negative effect on the performance and longevity of each drive.
One way to solve this issue is to spend a little more on enterprise-grade drives, which are manufactured using more advanced components and support various additional features. They may include error correction, vibration protection, and increased Power On Hours (POH). The more money invested will also result in superior performance, which is ideal should you be utilizing the NAS for larger files or intense use scenarios.
Dedicated NAS drives are a middle ground between desktop and enterprise drives. They're durable enough for shared storage deployment and usually come optimized for NAS use. Increased performance and better power efficiency can also be found in NAS drives compared to their desktop counterparts. Lastly, we have drives specifically designed for surveillance systems. These aren't recommended for a NAS simply because they offer lower random access performance.
