Naim NAS Test Tool and NAS Recommendations

I cannot find the NAS Test Tool mentioned in this thread - https://forums.naimaudio.com/di...ent/1566878604340111 .Please could someone direct me to the location of such if still avaliable- thanks.

Also as I am likely to be ripping my CD's to hard drive via a UnitiServe before too long I will be needing a suitable NAS as back-up.  The list given on the aformentioned thread is obviously out of date (c 2010).  Any recommendations based on users experiance and /or those currently available that have passed the NAS test?  I am not sure yet if I will go the SSD route so a 2 bay NAS is looking likely (I'm going through the steep part of the learning curve at the moment!) And I would prefere not to spend in excess of £300.

Many thanks,

Karl
