Hi there, Just bought myself a 2.8 mac pro with a stock WD Caviar SE 3200AAJS drive and would like some opinions about which hard drives to get and how to partition them. From what I've read on digilloyds site, I've concluded that it would be best to get a rather large harddrive with a small partition as bootdrive. The reasoning behind this is that data on drives gets read faster when that data is on the outside of the drive. So an 80gb partition on a 640gb drive would be faster than an 80gb partition on a 120gb drive, because with option 1, the partition physically remains small in regards to the whole, and therefore physically remains on the outside of the drive where seek speed is fast. So my questions are about the technical details really: 1) Is there a measured percentage as to where drives begin to lose their fast outer rim performance? If that's say 10%, then I could calculate: I need 80gb boot partition, so the drive must be 800gb. Also, to calculate how tiny my bootpartition should be, I need to know how many gigs "breathing space" the boot partition needs. Anyone? 2) What's your drives config and partitioning? I myself was thinking: - boot drive (how big?) - drive with 2 partitions, one 10gb scratch partition for the current project and one projects partition for things I'm not working on. - drive for reading samples from for drums etc. - drive for time machining the projects drive, the samples I can always reinstall from cd, so won't need space for that.. 3) What brand should I get? I was thinking Western Digital caviar black for the first three drives, and a more energy efficient caviar blue/green as timemachine drive. Do I need server drives like the R3 for any of this? 4) Where can my stock 320 drive fit in? Is it good enough for one of these jobs or is it just too old? I'm willing to replace it but I don't want to be splitting hairs. The potential replacement DOES have to add something in real world feel. Kind regards, Nicolas EDIT: Please read post 13 for an updated look on the situation.
