How to recover data from RAID?

I was wondering, I’ve bought a computer with RAID 0. However I read that there is no mirroring and it’s only there to improve speed. But what happens if one of the HDDs fails? Will I be able to recover data from the RAID disks?

If it’s possible to recover data from a single HDD then I guess you can’t just read it, but you need to rebuild the RAID?

Does anyone have experiences with recovering data from RAID setups, or is it just having luck?

There is no recovery from a failed RAID-0 array.
