I'm not sure exactly what you're asking, so apologies for posting some thoughts & questions which many not be helpful.

In my experience it's much more common to use "disc" or "disk" with talking about optical media such as DVDs or CDs. In this case you appear to be talking about storing to 2.5" and/or 3.5" hard drives, not about optical discs. Sometimes folks will refer to a hard drive as a disk, but the term "hard drive" is IMO much clearer. Just a FWIW for possible future use. > What you recommend or think on my usage... Huh? To repeat myself, I am not sure what you are asking about here. It sounds like you already have an eSATA external enclosure and SATA drives which you successfully use with it. So what sort of information were you hoping to get from the members of this list? > Lately i am thinking on put 2 fast and big HD on my 3.5 inch esata > cases... and replica with my 2.5 inch mobile devices... For faster > speed but no mobility. You would want to get drives with the newest tech ... by which I mean using disk platters with the highest bit density ... for the best performance. What size drives you go with is a separate question which would depend on other factors such as how you intended to use the larger drives. Whether or not to use 7200 or 5400 RPM depends more on the performance of your eSATA adapters and the systems themselves. 7200 RPM will be somewhat faster. Whether or not it will be SO MUCH faster that you notice a difference between them ... especially with the older tech in the powerbook ... is a question I cannot answer. There are other factors beyond the performance of the hard disk itself. How fast is the memory (RAM) bandwidth? How much of the theoretically available SATA bandwidth can the PCMCIA/Express card adapter use? If it were me, before doing anything else I'd try pulling the SATA drive from the MacBook and booting it via eSATA. That would give you a rough idea of what the experience might be like. I'm frankly not sure you'd see a performance increase which was big enough to justify the hassle of messing around with the external drives. (On the other hand, if you just want to "play around" for the fun of it, then that's a different matter, no? ;-) > How can i make it happen? Any replication software exist > for this kind of home folder replication in between discs? Every other time I remember this question coming up someone immediately jumps in to recommend the free version of CCC (Carbon Copy Cloner). I suppose such loyalty is a good recommendation in and of itself. I googled that phrase and here's (I think) a link to its web site. http://www.bombich.com/ While you can certainly use the free version) CCC, you don't need too. You can use Apple's Disk Utility in both Leopard (OS X 10.5) or Snow Leopard (OS X 10.6) to clone/copy a partition to another drive. When I installed a larger hard drive on my MacBook this is how I migrated my existing Leopard installation from the old to the new disk. I booted form the old drive and then used the "Restore" function in Disk Utility with the old drive as the source and the new drive as the destination. Then I booted the from the new drive to verify it hard worked. Worked great and I didn't have to bother with installing any other software. My personal opinion is that CCC appears to make more sense if you intend to create and then continue to update a (bootable ??) backup image of your drives rather than for doing a "one-time" copy of your image to another drive. -irrational john -- You received this message because you are a member of G-Group, a group for those using G3, G4, and G5 desktop Macs - with a particular focus on Power Macs.
