Hey there, @Derek Gomez!

It's highly recommended to have a purpose for your RAID array before creating it. You should also make sure you do regular backups somewhere off-site, especially if you are considering RAID 0 for a performance boost.
Either way, I'm not sure how much of it you are going to get as RAID-ing a 7,200 RPM and a 5,400 RPM HDD would bottleneck the speed of the 7,200 RPM drive and limit it to the capabilities of the 5,400 RPM one. You can indeed create and build the array, but I'd personally advise you to use identical drives.
If your budget allows it, I'd also consider RAID/NAS-specific drives as they are specifically designed for such environments.

Hope this was helpful. Keep us posted if you have further...

You can. RAID works best when you have identical drives though. If you put a 500GB drive in RAID with a 1TB drive, you would have 1TB of storage in RAID0 or 500GB in RAID1 -- your choice. The remaining 500GB would either be unavailable or configured as a legacy disk (meaning, single disk or JBOD).

Yeah, rpm doesn't matter (well it does, but not to the point where you can't use a raid) size is more important to match up
