I purchased my NAS 918+ and also purchased 2 WD10EFRX-68FYTNO drives to create RAID 1 using bays 1 & 2. Strictly wanted to mirror what my hard drive had on my computer in case of failure. Now I am purchasing a new desktop computer and thought I would expand on the storage of my NAS as I would now be backing up two desktop computers. When going to purchase two more of the WD Reds but a larger size than the 1 TB I now see all this info on SMR/CMR. Can I/Should I purchase SMR for the two new drives or MUST I purchase 2 of the CMR to put in to the other 2 bays. Thank you in advance for any assistance.
