no. I had a nas configured to raid 1 and something happened to the volume on it and I couldn't access the data. it might have been a virus or a hardware failure or both. I didn't realize that raid 1 only protects you from a HDD failure. if something happens to the volume, both hardrives get affected. so now i'm going to buy two new hardrives and have them in my PC and configure both as individual drives and do manual backups to make sure both are the same. I may end up getting a better nas later on and putting the hardrives in that, which is why i'm considering the WD red series. so are they alot slower or just a little slower? i like the hardrives because they use less power, less noisy and are more dependable. I don't mind if they are a little slower because I'm just using them to store my data. but if they are alot slower than maybe I wouldn't get them.
