NAS (Network Attached Storage) Buying Guide 2018: Storage Features & Functionality and Several Performance Rankings -

The "NAS Buying Guide" report has been added to's offering.

There are five types of NAS systems used for shared file data: NAS gateways, Integrated NAS solutions, Cluster-Parallel file systems, NAS accelerators and wide area file services (WAFS).

Some advanced file storage capabilities (see Features below) to look for in vendor NAS storage include: snapshot or point-in-time copies of file data; data reduction; and remote data mirroring/replication. Finally, as data centers consolidate more file data onto fewer NAS systems, high performance flash storage, high availability/fault tolerance, and non-disruptive upgrades should all be critical considerations.

A few new capabilities in the file storage space have recently emerged:

  • File analytics - this provides statistical and other information about file data;
  • Cloud file services/tiering services - this supplies file or archive services for specific public cloud storage providers; and
  • Object storage support - this supports native object storage interfaces and file access protocols to the same storage.

The remainder of this Buying Guide describes the various NAS products in detail, discusses NAS storage features and functionality as well as NAS system performance providing several performance rankings for NA storage systems. For example, in the NAS System Features tables below we identify feature availability and comparisons for over 40 current NAS product offerings from major vendors and in the NAS performance section we analyze NAS benchmark results ranking top NAS system performance using our NFS and SMB ChampionsCharts as well as provide top 20 NAS system performance charts for other performance metrics.
