- Heavy use of a network attached storage system can potentially slow down a network thereby impacting the users of that network. NAS is really not suitable where there is a requirement for a great deal of data or data intensive applications such as certain database applications.
- Because NAS is a shared resource, it must be administered effectively. For example, some people will capitalise on this and use the storage at the expense of others. As a result, it is necessary to set and enforce ‘quotas’ outlining who and how much can be used.
- Because network attached storage is a shared system, it is not best suited to be used in a ‘mission critical’ situation and as a result there can be no guarantee that the NAS will always be operational. This is not an issue with NAS itself but because of the nature of the environment that it is operating in i.e. many people using it as a resource.
- NAS uses standard network protocols to transfer information which means that it might not be as effective or as fast as alternatives.
- Network attached storage can slow down if too many users are trying to access it at once.
