Hello People, So the current place I am staying is kind of warm, well warm enough for my Drobo storage system to shut off due to overheating, even pointing a really good fan at it made no difference. It just does not like anything remotely warm :-| So I have decided to do two things, first to buy the NAS Drobo add-on and stick the Drobo somewhere colder, my current house is pre-cabled with CAT6. Now on the main thing, I have set myself an initial budget of £3000 but I will up it to £3500 is it worth the extra outlay. I am looking for a 4Tb system with a RAID system that actually works. Connection would be via USB or anything else apart from fiber...(got my money ready for g-tech with 4Gb FC when I get my Mac Pro later this year). So few things, company must be based in UK...er...that's it. I initially looked at the Netgear Ready NAS box but I need something with a decent active cooling system. Ah...most importantly...must be MAC and Win friendly I made my own PCs, etc so I can easily make things work together buy just and case and doing it all manually...ah...finally most important thing...must have four bays or more...4Tb kind of gives it away but just wanted to be clear on that. Thank you very much for ur help .OM.
