With software RAID, one could run both a RAID-1 array and a RAID-0 array on a single pair of physical drives, to get redundancy for important data, but an easily accessible common space for non-important data. Of course, everyone will have to weigh the actual probabilities against their own experience, and how important they consider their data to be. | |

| Sep 26, 2018 at 12:35 | comment | added | Kusalananda♦ | Just to clarify, the question is about setting up two disks in a RAID-0 configuration while at the same time not wiping one of the disks, right? | |

| Sep 26, 2018 at 12:23 | comment | added | Akhil | I am using just for testing to increase performance...How much probability can i expect of data loss (ie: 50%)and i which cases it to happen.. | |
| Sep 26, 2018 at 12:16 | comment | added | Jeff Schaller♦ | With 2 disks in raid 0, you get twice the chance of data loss! | |
| Sep 26, 2018 at 12:09 | comment | added | Akhil | Even if we have single disk, data loss is there...so what is the difference having a single disk or having raid-0 with 2 disks...? | |
| Sep 26, 2018 at 12:04 | comment | added | Mark Plotnick | Raid 0 on ordinary disks is only advisable when you either have good backups or don't care about losing all your data. (I've seen raid 0 on top of multiple small raid 5 arrays, and it was only done because the users couldn't afford a proper large array). It sounds like you care about losing data; do you have backups? | |
