Thanks for the replies but not really the answers I was looking for...
I'm more interested in pros and cons with the different setups, the actual drive(s) to use is secondary since when the time actually comes to buy there are probably other offers on the market than today.
* Is the setup process with raid worth it?
* Will I be able to add more storage by adding hdds on the same mobo if I use raid.
* Can I expect more failures?
* I read something about performance degradation over time when using SSDs - differences between single SSD and raid setup?
1- Yeah, and RAID 0 is very used for get performance.
2- Yeah, but you will need configure the other storage drives as single drives and not RAID mode.
3- RAID 0 is used for performance, but is very insecure because if one drive fail all the data will be lost. The failures is something relative, can fail in two months or can't fail ever.
4- Yeah, the performance degradation happen when u don't use TRIM.
I just wanted to vouch for the reliability of a RAID 0 setup. Theoretically, yes, the reliability of the array as a whole is 50% of the reliability of the individual drives, but looking that mechanical drives themselves have MTBFs of thousands and thousands of hours, there really is no reason why any of the drives should fail you.
Also, for my usage, I wouldn't really care too much if it did fail on me. I would just have to reinstall the apps and stuff. Documents are always on my dropbox.
Btw, I may be wrong about this but I've heard that SSDs in RAID 0 don't support TRIM. is that true?
