Hi All, Hoping to get some assistance in defining an external storage setup to work with new iMac and existing computer gear. Have browsed forums and found some useful info on possibilities but not enough to crystalise a solution for us. Existing IT equipment - DELL Studio XPS - Toshiba Satellite Laptop - Ipad v3 - iPhone 4, iPhone 3 - Apple TV - Netgear DG834G Router - Epson Artisan 835 About to Purchase - iMac 27", 3TB drive Following is a list of functions we'd like external storage to support. - Backup (iMac Mandatory as it will become main photo / music source, others beneficial) - iTunes Server? (Tell us if this is better left on iMac. We currently have 3 seperate itunes accounts. We'd like to have a single source that Apple TV, iPads, iPhones etc can access, sync with) - File sharing (allow central store - again, unless sharing off iMac better solution) Looking for a simple solution though computer literate and happy to invest effort if there is significant benefit associated with more complex implementation. Open to any ideas, let me know if further information is required to help provide useful answer. Thanks in Advance.
