Network attached storage (NAS) devices are among the most inexpensive and easiest-to-manage of any storage hardware. That has made NAS storage very popular with home users and small businesses, but NAS is also surprisingly popular with enterprises.
In the past, enterprises have often used NAS devices for remote or branch office locations. NAS devices' easy manageability make them a good fit for environments with few (if any) IT staff on site and where fast performance isn't a key requirement.
Today, however, the advent of affordable flash and scale-out storage means that NAS performance often rivals that of more expensive SAN hardware. A lot of modern NAS storage also has features like deduplication, snapshots, compression, encryption and compression that make them suitable for more enterprise use cases, including big data analytics and machine learning.
Because every enterprise will have slightly different needs, it's nearly impossible to select one — or even a dozen — best NAS. However, the eight enterprise NAS devices below offer a snapshot of some of the best NAS storage currently on the market. All are rack-mounted hardware, but they span a wide range of form factors, performance characteristics and price points. They are arranged in alphabetical order and the table at the end compares some of their key traits.
