Quick question, is it okay to mix two different drive speeds (10,000RPM and 5400 RPM) in one LUN?

    No there should not be any problem with it as long as they are 2 separate logical volumes.  LUN refers to one individual device so the 10000 RPM drive is one LUN and the 5400 is another LUN.  So they both would be on independent SCSI channels.

    The two disks won't be able to be configured as one RAID drive but it might work as JBOD.

    It depends on what you are doing. Home type stuff on low end hardware where you are not concerned about performance it will probably work, I have done it in my Infrant/Netgear ReadyNAS & some other cheap low end RAID arrays. I wouldn't mix drives in any type of professional situation however.

    Our NetApp FAS2020 will support using a bigger disk to replace a failed smaller disk, but you only get the usable capacity of the original smaller disk.

    What NAS are you talking about & how is it used?  I'd check with the vendor & see what they say.
