Best NAS (Network Attached Storage) devices 2021

Network-connected storage is more flexible, but that’s just one of the many benefits of buying a Network Attached Storage device. I have tested the top models to let you know which NAS device will work best for a home or small business.

Network Attached Storage

What can you do with a NAS device?
When you decide that you need to store files on a network drive, you need to figure out what you want to do with them, to determine the type of NAS device you need.

For example, a NAS device can help you do simple tasks like share access to Office files like spreadsheets and Word documents with colleagues. If you’re using a NAS to back up your laptop overnight, this task is pretty simple too. But if you’re streaming HD video over your home network to 2 tablets, laptops, and smart TVs at the same time, you’ll want a NAS that has higher specs in terms of memory, processor, and capabilities. network connectivity. You’ll also need a more powerful NAS if you want to store large media libraries, like a collection of 100,000 stock photos.

Like any computer peripheral, the features provided by different NAS devices will not be the same, to meet a wide variety of specific needs. Therefore, you will need to understand the terms and features before deciding to buy the device.

Which drives are used inside the NAS device?
Manufacturers selling diskless NAS drives recommend certain hard drive models, which have been tested for use with their NAS drives. These models may or may not resemble hard drives manufactured by that manufacturer. Take a look at these list of compatible drives before you buy the device. If you have more than one hard drive that you plan to use for installation, you will want to search for information to confirm that. If your hard drives are not on the list, that doesn’t mean they don’t work, but if you buy a new one, it’s best to follow the NAS manufacturer’s recommendations.

Some hard drives from HGST, Seagate, Toshiba and WD are specifically designed for NAS use. Most of these “NAS certified” drives were tested to run 24/7/365, a bit overkill for regular, consumer-level hard drives.

If you are looking at options from manufacturer Seagate, the NAS hard drives are called the “IronWolf” and “IronWolf Pro” series. IronWolf drives are a good choice after you have a NAS drive in your home. They are typically 1TB to 14TB in capacities. The IronWolf Pro drive is often used for business or commercial use. HGST drives are NAS Deskstar and Toshiba series of “N” series. On the Western Digital side, the dedicated NAS drives are “WD Red”, available in capacities from 1TB to 10TB, with the “WD Red Pro” line for businesses.
