Hi, So I've been buying hard drives quite often, selling old ones and upgrading to larger capacities and more bay enclosures, but to what end? I'd like to know what solution people suggest which has the ability to expand when needed to larger capacities at a good price? The major problem for me is that every time I reach my capacity with my current hard drive system I look at buying more hard drives and another enclosure or replacing the whole lot with a more elegant solution. I would like pretty much 2 or 3 partitions on my whole drive array however that may be setup. So I need "Time Machine", "Media", "Archive". Time machine backing up the media and archive partitions/drives as well as my macbook (soon to be replace by a Mac pro and macbook air which would connect to the drives through the mac pros network sharing I think). If these 3 partitions were created from multiple drives using OS X Disk Utility Raid 0 maybe. Is there a way to expand that raid without moving and replacing all the data on them? So for example if I had a 2 drives making a raid 0 for say "Time Machine" and I want to expand the time machine with another drive or upgrade one of the existing drives could I combine them all together without deleting all the data and needing to copy it all back over? I currently own 2x2tb western digital green hard drives (£65 couple of year ago) connected in an icebox 2 bay enclosure (£50 couple of years ago). I'm not very happy with the enclosure as I would prefer it to power on with the mac instead of flicking a switch every time, I also have to manually control the fan from off to 2 fan speeds. Also have a 1tb WD my book from 3 years ago. I was then thinking about replacing them with a 4 or 5 bay enclosure like a Lacie 4big or drobo but then thought, what happens when I fill that up in a couple of years! I suppose one solution (not sure how it couple work in terms of connections and multiple drives) could be buying multiple single enclosure hard drives and buying another hard drive when needed to stick into another single enclosure. So you start with say 4 enclosures (maybe all daisy chained with FW, estata or thunderbolt?) then in a couple of years time I need another 2 drives I could connect another couple of the same enclosures/drives into the daisy chain. If all the enclosures are the same the setup should look quite elegant as well as being easy and manageable to expand simply by adding to the daisy chain. Not sure about the many plug sockets though, or how this could work when wanting to maintain 3 visible drives/partitions/raid's. Summary I want to create an elegant solution which can expand in capacity through time possibly whilst maintaining the same appearance (3 partitions/drives/raid0's) Should be an interesting topic to discuss! I look forward to hearing your thoughts on the topic. Thanks, Luke.
