I need to have a RAID 5 backup of my music CD/vinyl/ home movies via a handheld video camera/digital photo collection> I am slowly but surely getting these imported onto my MBP15" i7 500gig HDD. I will go for broke and get a 8TB set up so I have heaps of storage as I am not sure what I will need by the time I have got all of my data imported and will need as my 500Gig needs to offload onto an external HD as it fills up with each lot of imported data. I have narrowed it down to either the OWC Mercury Elite-AL Pro QX2. OR a Drobo branded external HDD. I would prefer to not be locked into having to only use proprietry drives for a particular brand in the event of needing to replace/expand drive space. Given that I need this storage for the long term and will only be adding to it in small amounts rather than my initial saving of my collection. I am not sure which to buy. I will use firewire800 to import my data to my MBP and will eventually want to be able to access my saved collection via other Mac computers on a home network and also be able to stream data onto a home entertainment system. Basically I want reliability, speed, future proofness, quietness, and peace of mind in the event of any system failure(s). So does anyone have any thoughts/ advice with my situation A BIG thankyou for any help/advice Peter As an afterthought does La Cie brand enter into the equation as another alternative option?
