Xeshra: Still have to add: As long as your MB can not handle such a "card" for whatever reason then making a RAID setup will be useless because it will cut the possible speed, which will be a waste or simply inferior. So you do need such a PCIE-card for this to happen. For me there is not even additional costs as it was "included" and 100% compatible with my board, which is another IMPORTANT factor.
Depends on how fast you need it. Slow and steady works too.
Also zfs support in linux basically can give you any RAID options via a software model, certainly not as powerful as a dedicated supported card, but would still let you at least RAID-0 and append the blocks together. So it's not completely inferior. Plus the added ECC which is pretty cheap calculation-wise as long as there aren't errors.
Cavalary: Indeed. And, in case of games, that also means putting the saves (and settings, in some cases screenshots and what not) in the game folder instead of needing to search for them all over the user folder until you figure out where the heck that particular game puts them.
Only downside of saves and screenshots outside the user folder, is traversing all your data to another drive when you make a backup/restore or change drives, is you may lose that data unless it's selected/stored.
Though uninstalling said games, keeping the saves, and then backing up the game folder with all saves/extras (
outside of the base install) would certainly work too.
Timboli: So you are saying, that it all happened from the one external drive to a 500 GB partition on the second SSD, and that now there is a mysterious 120 GB missing on that partition, not in the game folder?
Wonder what the odds are, of temporary install files being 'deleted' to the recycle bin...
