Any version is that it's no substitute for backups. Also, I've run into too many situations where they use an onboard RAID solution and the motherboard dies which then devastates the owner when the array doesn't come up with what seems to be the same motherboard.
For years HDDs are totaled at 20 Watts each so you have more than ample power. Your diagram appears to be all about power distribution so that's fine.
Rather than 4 1TB drives why not a simpler 4TB single with externals for backup on a schedule?
HEY! I'm working on a new build and ordering all the parts this black Friday. Parts include
Case: 3 piece corsair half stacker (HUGE CASE)
PSU: 1000w Cooler Master V series
Mobo: MSI x99 Xpower
CPU: i7-5820k Haswell-E Cooled w/ Custom loop
GPU: MSI 770 Lightning for now (Will be getting 970 in the future)
-HDD's : 4x1TB WD Red drives RAID 10 (All saves, Important files and my music collection)
-SSD's : 2x 240GB Intel 730 in RAID 0 (HIGH intensive Apps/Games
1x 480GB Intel 730 (Boot Drive and other Apps/Games)
1x HP DVD Read/Write
RAM: 16GB Corsair Vengeance DDR4
My Problem is, I do not know much about power, and as you can see i am going pretty OVERBOARD on my storage. The drives are going to be in the top of me HAF STACKER. this makes cableing a problem because the HAF STACKER's top is about 24" away from where my PSU is mounted. I am planing on running ONE sata extension up to all 7 drives and then splitting it once up there (see picture for details). Will this configuration cause any sortage of power of overload anything? Will It work fine? if not, how would i go about providing all 7 drives (4 HDD and 3 SSD) with sufficient power? Thank You!
