So my future plan is to use 2 or 3 ssds in raid 0 with a small partition for windows and the second larger partition for games etc etc.now I know if one drive fails you lose everything.

Would the best way to solve that to be backup to some like a 4tb mech drive once every few days?
1.can you ghost a raid 0 array onto a single mech drive?
2.if a ssd fails would I be able to replace the dead drive re create the raid 0 then ghost the data from the mech drive back into the array?
3. Can this be done easily or do I need software like true image etc etc

Sorry for the questions raid is something I've never done but for the performance gains it definitely seems worth it.
 
Before you go ahead, read this from 2013.

One SSD on its own scores again in the contrived tests we put together. The performance differences when we boot up and shut down Windows 8, then fire up different applications, are marginal at best and not noticeable in practice. Single drives actually manage to outperform the striped arrays some of the time, even.
If you're planning an upgrade and want to know whether to buy a couple of 128 GB drives and put them in RAID 0 or just grab a single 256 GB SSD, for example, the answer still seems clear enough to us: just grab the large drive and use one. Using Samsung's 840 Pros as an example, a pair of 128 GB drives will run you £220 on Expansys right now. The 256 GB model sells for £180.

A good bit of an SSD's performance comes from the quick access times - which can be reduced in RAID configurations so for general use you don't always get the gains you'd expect.

Unless you know your going to be doing stuff where sustained flat out bandwidth makes up a good slice of the performance consideration I wouldn't normally advise RAID with SSDs.
 
I stuck 2 x 250GB 840 evos in raid and for gaming and general OS use I couldn't tell any difference from raid to single drives so went back to single drives.

I would either get a 128GB SSD for the OS and then a bigger one like 256GB or 512GB depending on funds as a second drive for games etc.

do you have a reason foe wanting to use raid at all?
