RAID 5 on gaming/editing PC?

[Aaralli]

I built a computer recently, but it only has a 1tb 2.5" ssd. I was thinking maybe I'll buy three 3tb hard drives and run it in raid 5... maybe even use a pcie raid controller? I don't know if it's a good or bad idea or even if it's possible, so someone tell me more about this. My specs are:

CPU: Ryzen 5 2600x

GPU: RX 580

RAM: Corsair Vengeance RGB PRO 16GB 3200mz

MOBO: MSI B450 Gaming Pro Carbon

Storage: Adata SU655 960gb

PSU: Bitfenix Formula Gold 650 Watt

1st of all, why do you want to even play around with raid?

whats the information you want to save in case of a crash?

raid can mess things up, real bad for your system

bad, get a single 10tb drive and be done with it.

I'm a photographer. Instead of building a separate DAS or NAS, it would be cool to keep all my photos, originals and edited on my pc. If anything were to fail, I'd be able to recover them right?

With RAID 5 you could indeed suffer one drive loss, but do keep in mind that RAID is not a backup and you should still make those for important things.

In theory you shoud be able to recover your data, yes! If one part of the system fails, thanks to the Data redundancy offered by a RAID set up (Not RAID 0) no data is los, however, as it was mentioned already "Redundancy Isn’t a Substitute for Backup". RAID offers some protection from single drive failure but this protection should not be confused as a substitute for a backup plan. It’s always possible that all drives could fail simultaneously, well this was an extreme example but more commonly is that user errors could result in the accidental deletion of data. You better get a larger HDD and make your life easier.

No. Say your motherboard fails, your data is lost. You can get a power surge that kills your PC including all drives. You could delete a folder by mistake - gone. 

 

That's why you need backups. RAID's only advantage would be to allow you to continue to work without interruption should one drive and only one fail.
