business -grade NAS.

I also prefer and recommend the Netgear READY NAS range, I think I have installed 4 so far this year (orders out for another 2 installations even as I write) and I put in 10 last year - mainly into small office environments, anything between 6 and 15 workstations. In most cases I was asked to 'get rid of the old server' because of a lack of expertise within the office to administer the system. NAS's seem to be gaining in popularity and word of mouth plays a big part in my customer area such that customers are recommending the NAS to each other rather than updating old server configurations as they grow old and tired (the systems, not the customers!)
I also agree that they are well featured and relatively easy to set up and explain to customers; I am not sure recent changes in the NETGEAR control panel layout has improved the setting up process, but that may just be down to personal taste.
However, my experience with PASTEL accounting suite is that when you use the NAS as a data store you must be mindful that if you set up the NAS by creating 'USERS' & 'GROUPS', and password protect the shares, you need to perform the initial transfer of the data to the NAS using ROBOCOPY or FASTCOPY (or a similar utility) that will preserve the ACL settings. Failure to do this leads to all sorts of 'permission' related errors. I dont know about other accounting suites, but I would think they are probably just as fussy over file access control?
