I am about to order a new TB-based HD/RAID system to consolidate ALL my files which are currently contained in a number of internal and external HDs (2.2TBs plus a 2TB Time Machine external). I was thinking about going with a LaCie 2Big setup (6 or 8TB) but just wanted your opinion before I bite the bullet...counting future storage needs and my growing iTunes library, would you say that 6TB or 8TB are enough for the next 5 years or so? Or should I go for the 5Big directly? I normally prefer LaCie's design and overall reliability, as I've faced no issues so far with their disks. Other brands to consider performance- or reliability-wise? My minimum requirements are: - At least 6TB of RAID 1 (3+3) storage; - TB interface; - fast and silent performance. Thanks for your advice.
