It's intended for permanent use -- it's what SRAM provides for permanently joining their chains.  I've got several thousand miles on them, with no difficulties.

Is the Power-Link designed for routine usage?
I think I am confusing the difference between some of the of busses, such as IDE, SATA, USB, and PCI.  What is the relationship between all four, how are they connected to each other? From what I read it seems like PCI connects them together as well as to the CPU, but it's not clear.  Any help would be greatly appreciated. I am cross referencing this post with another I made about the Linux commands to browse them.  http://unix.stackexchange.com/questions/27414/ide-and-pci-bus-commands
