ack!!! stay away from TBU!!!! they are terrible and make you do the job twice. the server is a cool route if one has the $$ to do that. That's why i kept to the multiple HDD in the system. my current layout is C:(10GB) OS related files, and drivers D:(13GB)the off line models and OBJ and textures and loose 3ds/OBJ files E:(30GB) POSER4 also i have a 20GB USB HDD that also gets used as straight storage or i could use MS backup and point it to that device. The dvd-ram is a good idea but I would wait a bit more for the tech to catch up with it. as now they are less stable as one may think.
