- Inflexible licensing model requiring booting/running from a low performance USB stick - Forced paid licensing - I prefer having a choice - Lack of striping performance is limited to a single hard drive speed. JBOD + Parity is limited in speed. - Highly proprietary - You depend on the vend...

When adding a parity drive, the hard drive must be the same size or bigger than any other data drive in your array. You can add up to 2 parity drives. If you have more than 6 data drives connected, I would recommend having 2 parity drives set up. Like that, if 2 drives happen to...
Unraid is also efficient in how you can expand the size of the array. You can add a drive of any size, and it will increase the size of the array by that size, even if it doesn't match the size of the other disks. As long as you ensure that your parity drive is equal to or...
