I've come to the conclusion if you need that much storage at home you're into some seriously kinky stuff..
like many of us on here with home servers, Mine too is used to house all my movies hd and not but mainly in HD. TV shows, music and more. if which hw that fails? I am using a raid card with an expander. if the expander dies i can get another one, if the raid card dies I have a spare same model Data would still be intact i would just have to swap out the failed part. as for the kinky stuff, non of that is on my server lol,,, they are stored on the my old drives in a box.

If you don't understand how expanding works and how writing entire drives at a time is a huge risk, you won't grasp that this sentence in itself is an explanation. I never said you can't mix different drives, I just said it's retarded, risky, and only hurts performance. My philosophy is "go big or go home."
I test all drives that i buy...I understand your concern ramicio but expanding itself doesn't put the data at risk, it is failed hw that does that...so we are always at some level of risk. if a batch of drives die during an expansion then yes there will be trouble, if a batch of drives die at idle, there is still trouble. if data is at such a high concern, there needs to be a backup plan in place. my server is not backed up, it is just not practical for me to backup the entire 30plus TBs but i do have a folder that is backed up local and offsite for my most valuables. buy and building a server with all drives populated at once just makes no sense.. even if you have the cash. again the downside of doing it all in one shot.
1) higher electricity bill for drives not in use but spun up.
2) premature use of drives that are not being used or filled but spun up.
3) waste of warranty on drives that are not being used but spinning
4) price changes on drives, could have saved a few hundred if you got them spread out in time as you needed them.
5) as already mentioned, the chance of landing drives from a bad batch
as for drive models no longer being available.. this is true but not a problem, the newer version of the drives will not only most likely be cheaper but will only perform as your well as your weakest drive.
My setup started with 2tb hitachi 7k2000 drives, I needed to expand and could no longer find 7k2000 drives so i moved on to use 7k3000 drives and no performance issues. they are all still 2tb drives. and all still hitachi drives.
