Question: how risky is raid 0

[MouthSmasher83]

With just two 2.5 inch ssds how risky is it? Should i do it?

If you need the performance without messing around with raid, just get a decent NVMe SSD.

If one drive dies you lose all of your data, so it's not really worth it as the speed increase isn't that much and won't be too noticeable in most cases

When putting 2 SSDs in RAID 0, the odds of losing all your data are twice as high as they are if you're putting your data on a single SSD. 

If you have SSDs that are known to fail often, you'll almost certainly be in big trouble real quick.  However if you're using SSDs that are known for their reliability, I wouldn't worry too much about them. 

Make sure you use good data cables to prevent CRC errors (I had a drive get kicked out of a RAID5 array once due to a bad cable) and do regular backups just in case one of the SSDs fails.

 

As for performance, you won't really notice the difference ... until you go back to a non-RAID setup and get annoyed by having to wait just that tiny bit longer for everything.

SSDs in RAID doesn't give any actual extra application or OS performance, in fact it makes it slightly worse. SSDs are very fast and have very low access latency so adding RAID over top of that actually slightly increases access latency.

 

You will get faster large file read/write performance but that isn't usually worth it. I put my SSDs in RAID so I can have a single larger volume and not for extra performance, I need that single large volume though otherwise just keeping them separate is better.
