External hard drives

Depending on the application, we recommend that you pay attention to the following characteristics when purchasing an external HDD:
If you are primarily looking for a portable hard disk or want to exchange
data between different devices in an uncomplicated way, a 2.5'' hard disk with power supply via an integrated USB interface is the best choice. These smaller hard disks usually have a storage capacity of up to 5TB.
When selecting the connection, the speed differences are shown. Most manufacturers today rely on the fast USB 3.0 standard. Newer hard disks already have the universal USB Type-C connection. Individual models also have the option of exchanging data via WiFi.

For home users who want to back up their documents and multimedia data such as holiday photos, we recommend external hard disks with a size of 3.5'' and a storage capacity of 4TB or more. For Mac users, it is recommended to consider products with the fast Thunderbolt 3 connector.
Backup systems with a storage capacity from 8TB and RAID function are suitable for companies or for backing up large amounts of data. Rack systems can also be considered for larger storage capacities. These offer extremely much larger ones and can be built into the server rack to save space. But here it will be interesting to have a look at the category [Network Storage (NAS)](https://www.digitec.ch/de/s1/producttype/netzwerkspeicher-nas-68), because there you will find the bigger feature set.
