Are there any benchmarks or studies available comparing vinum (before 
GEOM), vinum with GEOM, gmirror/graid3/gconcat/gstripe, RAIDframe, other?

Or can you point me to some reviews that compare multiple volume 
management systems?

Also, is there any mechanism for removing physical disks without using 
mirroring, such as telling the volume system that disk will be removed so 
it checks to see if it can move and then moves the data automatically to 
the other disk(s) and marks the disk unused?

Thanks,

 Jeremy C. Reed
