One of the biggest overlooked features of macOS is Time Machine, this system quietly performs an automatic backup of the entire contents of your Mac's hard drive every hour.
If you accidentally delete a file, you can go back and view all previous versions of that file that you've saved.
If your Mac starts behaving weirdly and you think you've been infected with malware, just restart your Mac and use Time Machine to restore all of macOS to an earlier, untouched state.
Of course, for this you need to have an external hard drive connected to your Mac and capable of storing all your old backups. To avoid accumulating HDDs/SSDs, there are NAS servers.
In this article, we'll show you the best on the market, and if you want to learn more about the benefits of NAS, how much storage you'll need, and what features to look for, jump straight to our buying advice below. our ranking.

What are the advantages of a NAS server?
Rather than connecting your hard drive to a USB or Thunderbolt port on a single Mac, consider NAS (acronym for Network Attached Storage Server) server. You can connect it through an Ethernet port on your home or office router, and its storage space can be shared by everyone with access to your network.
Early NAS servers were expensive and complex, and mostly used by large companies that needed a central backup device to be shared among multiple employees.
These days, most homes have their own Wi-Fi network, operated by multiple people often with multiple devices.
How to choose a NAS server for your Mac?
Here are some essential features to take into account before any purchase of your future NAS server.
Time Machine support
Most NAS servers are compatible with macOS, but not all of them are "engaging". For example, some NAS will not allow you to take advantage of the Time Machine to perform network backups.
Time Machine support is therefore an essential feature to consider.
User accounts and shares
It is also very important to have the possibility of creating individual accounts, so that each person can have their own space on the NAS disk, and shares.
Which most NAS do, but sometimes it takes a bit of know-how to understand how each drive handles this process.
Mobile device compatibility
It is also very important to ensure that the desired NAS offers an application for iOS/iPadOS. Most Apple users back up photos, videos, and any other files to iCloud from their mobile devices, so it's reassuring to have a backup backup on your NAS.
A good NAS box will also allow you to share photos and videos and provide the possibility of remote access.
streaming
Many people use their NAS drive as a central media server for their home. For example, by streaming music and videos on a games console connected to their TV in the main room. Mac users should check if a NAS drive can stream files to an Apple TV, or act as an "iTunes server", storing your music collection on the NAS drive so that it can stream music to each Mac or network iOS device.
How much storage do you need?
This is entirely up to you, but it's worth mentioning that some NAS drives are more flexible than others.
Some NAS come with a built-in hard drive, usually at least 2TB, but the hard drive is fixed, so it can't be replaced when full. However, the NAS has a USB port to connect a hard drive and add some additional storage.
NAS without hard drive
However, many NAS are sold without a hard drive, they simply provide two or more empty bays in which you can insert the hard drives of your choice. They are more expensive but allow you to customize the NAS with the desired storage space.
Also, if you're not satisfied, then you simply remove the old discs and insert new, more generous ones.
This type of NAS drive usually also offers a number of RAID (Redundant Grouping of Independent Disks) options, i.e. the use of multiple hard drives for additional performance and data protection.
