I thought that if you do that, SME will pick them up as a RAID, thereby only really using the hard drives as one drive.
In my case, both drives are approximately the same size, so in order to achieve any benefit, I'll have to use them in tandem - not either/or.
Since you've suggested an option 3, does that mean that the first two are not possible, or merely difficult.
Thanks for any further guidance.
