October 13, 201312 yr Is it so that the server runs very slow when a disk is over 90% full? How do I set a limit to the write capacity?
October 13, 201312 yr Writes get very slow when a disk gets very close to capacity (e.g. 90%). Reads aren't impacted at all -- you can fill a drive up with no performance issue for reading (other than the normal slowdown for the innermost cylinders of a drive).

Reads aren't impacted at all -- you can fill a drive up with no performance issue for reading (other than the normal slowdown for the innermost cylinders of a drive). There's no provision to limit the write capacity in UnRAID ... but if you set any allocation method except "fill-up" it will maintain a reasonable balance on the drives until your array is so full that there's no choice.
October 13, 201312 yr Set min-free-space for all shares. That works as long as you only write to shares -- not to the disks themselves. It also is not a percentage -- it's an absolute value; so unless all drives are the same size, the percentage of unused space will be different on each different drive size => potentially a lot different if there's a significant variance in sizes.
