1TB and 2TB HDD

Solution
Bigger are better if u gonna store music movie etc...

but i recommend split the movie and game disk if u gonna run both on same times
I often listen to custom music (sometimes + downloading) when gaming, so when they accessed both in parallel it reduce disk seek time...
if u not going to multitasking, one drive is enough

It really depends how many games, movies and songs would you install and on that HDD gonna be your OS booting drive.
What you must know is some drives are rather used as a storage devices than a performance drive.
In that in mind I'd rather choose smaller but faster device as a SSD drive or for example Caviar Blue (which series for now is limited to 1TB) for an OS drive and some Huge Caviar Green for a storage device. Mounting a single super-fast drive is kind of waste and on the other hand putting big and lazy drive is no the best solution either.
If you are cash limited rather buy some decent but smaller one then when you are filled to the last byte, buy some new storage-like device.

Its only partially true if you think from economy point of view.
If the HDD is like you said ONLY as a storage device then buying cheapest and biggest drive makes a sense.
On the other hand high performance drives over 1TB are overpriced.
Just as an example Caviar Black 2TB can cost about the same as 1TB Blue and 2TB Green so in price of 2TB of all type usage drive you have a specialized and stable 1TB drive and a mass storage 2TB drive.

Well I'm only used standard 7200rpm disk (Caviar blue/barracuda) in my system.. so In my mind bigger are better..

The Green ones "5200 rpm" is simply to slow even as a data disk and the red/Black/raptor too expensive to consider... I would rather go with ssd..

5200rpm is a failure disk that should be avoided, even the manufacturer said/admit it was (seagate & WD), the power saving is not much since 7200rpm can do task faster hence the power used stop much quickly....

1) Caviar Blue series have max 1TB drives
2) Barracuda is also available as a Green series (5900rpm) which seems to be surprisingly fast so thats the opposite to what you are implying.
3) Storage device in definition moves data rarely, for watching movies or listening the mp3 its far more than enough. Paying twice for the 10-20% speed boost isn't reasonable in that case.
4) If you have 1 HDD, if it fails you have lost all. If you have 2 drives the most probably the OS one will die first since its online almost all the time, used more often so will meet MTBF quicker. The data storage on only spins up (ofc if you setup it like that) when you need it. So generally your data collection is rather more safe.

Personally I'm using 64 GB Intel SSD for SRT, 1TB Caviar Blue for an OS + IO fragile data and 4TB Caviar Green for copy and forget data. Thanks to SRT you are getting enough boost to forget about the classic hard drive limits.
Ofc I'd rather have 5TB of SSD drive but that would cost far more then its worth.

Maybe it just me but I'm cannot stand the speed on 5900rpm drives when i tried to run/copy/move something..
I once use a 5900rpm drives in my office pc with all cramped in it (OS, Data, apps) it quite a bad experience
(that before I tried ssd, u got to try ssd when u got extra money :D). also my collection quite large and often moved/added, but hey it's a preference or maybe it just me...

Seagate is using barracuda names for it's 5900rpm and 7200rpm drives I was referring the later..

anyways i suggest to avoid 5900rpm drives and if the biggest of the 7200rpm drive u can get is 1Tb then the 1Tb that u should aim...
and if u like to multitask split the drive for it's specific purpose is better, it helps performance and reliability..

btw u need to care when buy hdd do a testing after setup lately newer model hdd is more prone to failing i got some drive that fails before a year,
contrast with my 7 & 5 old year old hdd that still running fine.......

That. Thats why I'm not using Seagate drives anymore since in few last years 3/3 of their drives was sent for RMA.
I might be wrong or unlucky but when you burn once you are somehow more careful in the future.
And thats exactly my point while having 1 drive only is a bad choice nowadays.
Yes you are correct to not use low rpm drives in general as a single drive, its bad in so many ways.
But when you consider they are cheap, its perfect as a backup/storage device... who burns cd/dvd/br nowadays when its actually more suitable/faster/economical to simply buy a huge cheap drive, put crap on it and even detach it and put it to a rat hole. Its funny but true.
You must remember another thing, copying files from a slow as crap HDD to another drive will in vastly most cases be faster than copying files within the same but fast drive, since in first scenario both drives are doing a single job (1st reads, 2nd writes) in a single setup one drive do both thats why its theoretical read/write speed is almost a half.

I'm not gonna put more arguments about perfect everyday usage solution because there is no such, but to finally answer the topic question:
1) 1TB is enough for a gaming rig?
Of course it is... an OS needs how much 10-30 GB and an average game needs mostly 5-20... count yourself.

2) Is it good to have 2TB drive?
Ofc it is, bigger is better (for some)

3) Is it economical, safe or optimal setup?
Read all the posts above... its far from being a YES on all those questions.
