Disadvantages of NAS

Network Attached Storage has the following disadvantages:

 

  • Heavy use of NAS will clog up the shared LAN negatively affecting the users on the LAN. Therefore NAS is not suitable for data transfer intensive applications
  • Somewhat inefficient since data transfer rides on top of standard TCP/IP protocol
  • Cannot offer any storage service guarantees for mission critical operations since NAS operates in a shared environment. Only local disks and SANs  can be used to provide some service guarantees..
