Expend space and other questions?


#1

I’m about to buy the ex4, a few questions:

  1. Can I only buy one hard drive first, add more later, then charge the raid mode but won’t lose data?
  2. Ex4 vs pro4, is there any data transfer speed differences between them?
  3. Does ex4 support WD Red 10TB NAS Hard Disk Drive or Seagate 12TB IronWolf NAS SATA?

Thank you so much!
