While it makes sense in theory, the data doesn't support the need to work in your drive. Not only will a few weeks not really make an impact, the failure percentages don't really work when looking at only two drives. While there has been some indication of more normalized failure rates when it comes to drives of the same model. Most age-related results ...
You can do, but it won't help too much. For example, if there is a needle in the input power, the same needle will kill both disks. What is important: you need to have a good backup. Raid doesn't make up for a good backup. Actually, if you have a good backup, maybe a mirroring raid isn't surely needed (if you can tolerate a system collapse once around 2-3 ...
This is usually an argument for SSDs more than HDDs in my experience. SSDs have limited write cycles, therefore if you use a RAID1 with two SSDs of the same model, both should run out of write cycles near the same time. As for general failures, unless you have a serious issue like mass vibration, static, or high heat; I don't suspect you'll see 2 out of 2 ...
Great Question - However, unlike automobile headlights, this is a waste of time. The MTBF [mean time between failures] rating for 4 GB drives [WD Red in this example] is 1,000,000 hours. The odds of two drives going bad in a mirror at the same time is extremely rare. When I have seen this happen, it is has been because the first drive failed without ...
It may be better to use different brands or series of disk together if you're worried about this. I have seen disks of similar type and age fail in clusters, so IMHO it's not an urban leend.
It's a waste of time. You won't be able to induce failure or stress the drives in a meaningful manner. You have RAID, and that's a good start. Just make sure you have monitoring in place to actually detect failures as they occur and backups to protect against disaster.
