Rec./best HDD...? HGST

[frldyz]

Background:
1. 1st build.
2. 3 mos. ago minimal computer knowledge. Went from learning what wi-fi and Bluetooth is ---> challenging myself to do a build.
3.. Will be basic home PC. Mainly file ( pic and home video storage ), with possible gaming. Nothing crazy....?

What I have so far:
i7 4790k
gigabyte Z97X gaming 3 mobo
Noctua NH-D14 fan/heat sink
Crucial Ballistix ( sport) 16gb RAM - 2 x 8gb sticks
Corsair AX 750 PSU
LG Blu-Ray internal optical drive w/ burner and BDXL
Samsung 500gb 850 PRO SSD
Internal card reader (don't laugh)
Corsair 760T case

What I still need to get:
HDD - for file storage
Another larger External HD
OS _ Leaning towards Win 7. We have 8.1 -HATE it!!!
Will more then likely upgrading my exhaust fan
Would like to add an additional fan on top or underneath HDD or HDD cooler case/fan
GPU- Want to run 3 monitors. Nothing crazy like 4k or too insanely expensive. Mainly because we have lots of windows open ( online ) @ a time. Do not intend to game with 3 monitors ( if I even game...?)

_______________________________

So I want to put the most reliable, least amount of failure HDD in. Would like to go with as much gb storage as possible. ( Even though it will be backed up on an external HD). Not sure if I am going to RAID1 as an additional HDD in case 1 fails.

After doing mainy searches and reviews. It sounds like the 4gb HGST got some great reviews.

Thanks everyone.
Would like to keep this as simple as possible. Nothing insanely expensive. Would like to keep $200 or less per HDD.

Nice choices but above all make sure you are static free so you do not kill those parts.

Maybe buy a can of anti-static spray.

When you say home video storage, do you intend to do much encoding with it ?
Otherwise the i7 would be a waste of perfectly good silicon.
Likewise with the PSU, 750W is way too much unless you're getting a top of the line GPU. But then again you're not gonna use it for gaming.

Any particular reasons for not liking Win 8.1 ? I dislike it as well in the beginning. But installing a start menu replacement fixed that and now I basically have a Win 7 with improved internals. I especially like the faster boot. It feels almost instantaneous with an SSD.
