Can you have 1 SSD for OS and Applications, 2 SSDs in RAID 0 for games and gaming applications such as steam, origin, battle.net, etc, and 2 HDDs in RAID 0 or RAID 1 for media such as movies, music, videos, pictures, school work, photoshop projects, after effects projects, cinema 4d projects and important files at the same time and in the same system?

1x850 EVO 120GB
2x850 EVO 250GB RAID 0
2xWestern Digital Black 2TB RAID 0 or 1

Yes.
However......you should really, really not do that.

2x850 EVO 250GB RAID 0 - Fail. There is no reason or benefit to running the SSD's in a RAID 0. You gain zero performance benefit, and add a large fail factor.

2xWestern Digital Black 2TB RAID 0 or 1 - What are you actually wanting to do? RAID 0 and RAID 1 are two very different concepts, and used for different reasons.

Slice it up however you want, but you gain nothing by creating raid 0 or 1 on ssd's. As for the HD's create a mirror - raid 1 to protect against accidental loss and see an increase in speed. Remember-back up and back up again.

Given those drives, this is what I would do:

1. 250GB EVO #1 - OS and applications
2. 250GB EVO #2 - games
3. 120GB EVO - Docs and working files (school stuff)
4. WD Black #1 - music/video/pics. Other games.
5. WD Black #2 - photoshop projects, after effects projects, cinema 4d projects, and backups for #1 & 3.


This is actually not much different than my current setup.

usafret...
can you link a article on the ssd raid 0 thing you stated above ??

RAID 0 is more like AID 0 as it has no redundancy. if 1 drive breaks then you lose the whole array. but it does give you faster read and write speed

''Not with SSDs. ''

do you mean the speed or the redundancy part ??

page 1
The only drawback is that, if one of the drives fail, all data contained in the array is lost. So, RAID 0 is recommended when performance and disk space are more important than reliability.

conclusion
In sequential read and write tests, as well as in the random tests with 512 kiB blocks, using a RAID 0 array provided a considerable gain in performance compared to a single SSD, with a typical improvement around 80 percent, but reaching as much as 324 percent. Therefore, it is clear to us that instead of buying a single, large-capacity SSD, it is better to have two smaller-capacity models configured in RAID 0.

In theoretical benchmark results, SSD + RAID 0 can bring spectacular results.
In real world use, not so much.
