"I do a lot of RAID, and I am so picky I want the same 'batch' of the same exact drives. "
I totally agree -- my most recent 8 disk RAID 6 build had to have all the same batch of Hitachi 7200 rpm 3tb drives, and I made that a specific request in my Newegg order, which they fortunately got right.
Yup checked that too. Also tested them all a bunch before using. I was very lucky to buy them before the flooding at $150 each.
It's my home media NAS with hundreds of my BluRay disks and many hundreds of my DVDs in iso image form -- easier to play on my HTPCs and protects my disks from careless family members, plus a lot easier to actually find the movie than digging through disks.
I didn't want to just use a QNAP like I do for clients, so I used an Adaptec 6805 adapter/Intel i3 2100/ASUS Z68V (all on pretty good sales), overkill but I had some extra money at the end of last year, which is rare nowadays. I have room for another adapter someday and the case has room for lots more drives if they ever get cheap again, a huge LianLi full tower I had in the closet.
