For the OS, the transfer rate is relatively irrelevant. It is the Access time that counts. But the relatively small difference would probably not justify a reinstallation (unless you want to do it for other reasons anyhow).

The small difference in access time will probably hardly be noticeable. The same problem with Raid. It speeds up the tranfer rate, but not the access time. But the OS typically transfers small amounts of date, however it has to get to it fast (access time). Raid is interesting for moving large amounts of data. So if you want a data partition to which you frequently move videos or other large files, then Raid might be in order. But even then it is more of an academic excercise than of practical value. The few seconds you save may not be worth the cost, effort and added complexity, plus the risks especially in a Raid0 setup. I a mirrored Raid that would be different, but that is another story.
Sounds clear for me now, I appreciate your help thank you
I got some interesting informations about Raid0 and Raid1, it looks pretty difficult and exaustive indeed (for a very small difference at the end, as you said). I decided not to change my configuration, at least until I'll get another HDD or even SSD.
Anyway, the results of the tests of my two HDD are not so bad at all, I am glad to have some great stuff even if I did not care about it till yesterday! ^^

Is there a significant difference between AHCI and IDE modes? Wiki didn't help me so much...in AHCI mode
My MB default setting is the IDE mode but I have never tested to put it into the other one like you did.
AHCI is no guarantee. You can read about my experiences and personal opinion on this subject here:
AHCI - DON'T Forget it!
Here you'll find some objective and usefull information and YES, you can switch to AHCI mode without having to re-install your OS:
