HDD Replacement - Expected Rebuild Time

quazi_dude, in my humble opinion, these units are very reliable. Several months ago, I rehomed a 5 year old NV+ by giving it to a friend. He is very pleased with it. I have two 4 bay NVX units that are now two years old, and while I had some start up problems with the first due to a non compatible third party switch in the network, they have operated flawlessly. I do not include the drives in that as I have had a few fail in the past two years, as compared to only a single drive failure in the first three years. After all, Netgear does not make the drives.

I joined the lost data club decades ago when everything was on a single drive in a single PC. I learned my lesson and have not been without a viable backup since, especially since I am more vulnerable to failure now that everything in on the computer with few hard copies. I pointed out that I had two NAS units, one is the primary and the other is the backup. In addition, I maintain an offsite backup of all my critical/important information (financial data, photos, etc). Videos and music not included as I do not consider that important, just nice to have. I can always go back to the DVDs and CDs.
