The best drives for NAS | April 2021

Do you have to store a large amount of data? You just have to buy a NAS, devices designed to store huge amounts of data and make them available 24 hours a day on the network; such data is saved on hard disks specially developed for continuous use. In NAS (acronym for Network Attached Storage), it is not advisable to insert traditional HDDs, in fact, units that can withstand intense workloads (video surveillance, continuous access to data, backups, RAID, etc ...) are needed.

This is the main difference between traditional HDDs and NAS disks: the latter are designed for continuous operation, are usually slower, but develop less heat and have more cache memory to speed up file operations.

Another aspect to keep in mind are the data storage technologies: SMR (Shingled Magnetic Recording) and CMR (Conventional Magnetic Recording). The former is used on traditional HDDs as it allows you to store more data on disk, however it is not suitable for the intensive write operations of NAS. The latter is used on NAS HDDs, as it offers superior write performance under heavy loads.

We have compiled a guide to the best NAS drives, products suitable for both individuals and small and medium-sized businesses, and have classified them in ascending price order.
