Hi everyone...... first post! I have just bought a dual 2.8 8 core Mac Pro and am after a little advise on how to get the best from its hard drive performance. The machine is all stock apart from the 8GB of ram I bought with it. I will us the machine for my business as a commercial photogrpher (stills only) and using the Mac OS only. Games and TV are of no interest to me with this machine as it will only be used with PS CS3, Lightroom, Capture One Pro and the like. I am looking at adding some hard drives but wanted some pointers as to what to do. The machine is still in its box so nothing is set up, so ideal to change anything at this stage. I understand the stock 320GB HD is pretty rubbish so was wondering do I get somthing else in its place? If I do, is it simply just a case of taking the 320 out and replacing it with something better and then just booting the machine from the supplied setup DVD's to set up the new HD? Which drives are recommended that are at a good value/performance level to be used as: 1. System Drive 2. PS Scratch disc 3. Storage drive Thanks in advance. Gareth.
