Which is better from 6x1Tb raid, or 3x2Tb 2x3Tb?

Hello all and happy new year!

The essence of the question is: which configurations are more optimal from a 6x1Tb raid, 2x3Tb or 3x2Tb for the HOUSE? I'm interested in the optimality, in terms of recovery if the amount of RAID drives over 1tb and the consumption of electric. energy if disks 6 or 3pcs.

So, what advise from the raid under the following tasks:

1) storage films with the possibility to easily add drives and some sort of reliability (maybe raid5?)
2) possession games with great read speed (well, there is so clear raid1, but maybe there are other options) upd: ssd is not an option games on 3Tb typed.
3) storage of virtual machines, preferably with the possibility of recovery.

upd: made a mistake for games raid0

Solution
- about RAID5 forget as about a bad dream
the difference in power consumption penny

prioritize:
- greater number of spinel (disks) anyway will give you more speed
- "painless" adding disks to an array only know how hardware RAID controllers
- RAID 1 will "eat" half of the drive capacity

6x1 tb just perfect for raid 5, and it is better 4x2 TB, as kopeck piece is better in terms of price and volume. Games much better volume and low - cost ssd the speed will be much better. To mirror game why? In which case they quietly pumped.
ATP for the Board) the ssd is unfortunately not suitable games accumulated 3tb, and I was quite satisfied with the speed of 7200rpm hdd - Augustine_Ro commented on April 4th 20 at 01:03

If you are just storing games, what raid-5 is not podhodit? Just put it into hardware decision. The read speed from raid-5 high. Write speed depends on controller, but for games - enough, they say almost nothing, read more.

So again, 3 TB of games that you constantly play? Why not take a small M2 SSD on which to put it, what are you playing right now?
If you are just storing games, what raid-5 does not fit?

Many write about what 40% of failure of the raid5, I had never experienced so I don't know what to expect.

Modern games take up a lot of space especially 3A projects, and especially strategy. Ssd to date, in my opinion, the game is expensive. - Augustine_Ro commented on April 4th 20 at 01:05
@Augustine_Romodern AAA projects for a couple of nights passed and removed. Terabyte SSD is worth 6 Grand, this will be enough for a dozen of AAA, a couple Mmoshek, and a couple of sessional. How did all this can at the same time to play? Not well, to each his own, but held half a dozen games at the same time...? - Russ_Reinger commented on April 4th 20 at 01:08

Don't know for 10 years never failed. Hard drives in the RAID varied, the RAID did not break. Just don't buy nonam.

Then there is money to рейд5 and pile-drives you have, and ssd of 256 GB no?
I can tell at least one game that won't fit on a 256 GB? Or you for day play 10 games level 3A projects? - soledad.Veum commented on April 4th 20 at 01:11

Here you have missed an important, in my opinion, the moment capacity of the first embodiment will be 5ТБ (RAID5), the second - 4TB (also 5), the third - 3TB (RAID1).

storing films with the possibility to easily adding disks

This will require the controller, as well as some no, but skills. We regularly bring data recovery RAID arrays after the incorrect rebuild.
Well, RAID1, of course, drives you can add is that for greater reliability.
