hey everyone, I am looking to replace my Imac's (late 2009) harddrive (1 TB Seagate drive just died) with a 2TB hard drive. I read a lot on the forums on Caviar Green and Black series but still have some questions. 1. Which drive do you recommend for the Imac? Primary use for me would be to use the Imac as a media hub for Itunes, Iphoto and VLC. Am also planning to use it with the new Apple TV. 2. How much faster is the black series compared to the green series? (e.g. 10% or more?) 3. How does the Caviar Green 5400rpm compare to the Caviar Green 7200rpm in terms of noise and speed? 4. Will any 3,5" drive fit into the Imac or are there any limitations such as with the new mac mini? many thanks in advance!
