Duo - Mis-Matched HDD Size Compatability
Dear All,
I have an RND2100, with the two 1Tb HDDs in it. I have owned it for about 3 years now and I am getting the dreaded warning about an imminently failing HDD.
Having checked the HCL, I have found that the 2Tb drives are cheaper than the 1Tb drives. Can I replace the failed disk with a 2Tb drive, then when the second drive inevitably fails in a few months, I will do the same. I understand that the RND will be limited to the smallest drive during the interim phase. Is this the only restriction?
RND2100, RAID1.
Thanks Ed.

- It is.
However, just because one drive is failing does not mean the failure of the second is imminent. Also keep in mind that during the resync process there is a lot of strain on the drives, so if the second drive is weak, that is when it could fail. Of course a second drive failure occurring during the resync would most likely cause data loss. For that reason if you are not currently maintaining a backup (recommended) then it is a good idea to create one, if you have one, make sure it is current.
