The current default file system for any new installation is now ex3. I have a RAID0 over 2 x 186GIG + 2 x 20GB over 2 HDD. The current file system format is reiser + Encryption. Previous to that I had the same RAID0 config however I was using ex3. The / partition is also reiser, without encryption unencrypted The /home mounted partition is reiser without encryption I have noted that using reiser in both / and /home directory appears to offer a speed boot load that is just a small bit faster and mounting of the RAID0 partition (encrypted) takes a shorter time. Overriding factor change in O/S from 10.1 -10.2. Just going back to file systems - which is known to be faster and which is know to be the most stable. I understand the 2 may not be == Without offering an epistle can a few people who do know give me an answer. Some slight technical description for your logic would help me a lot . With respect to file systems info you don't need to dumb down your words much for me in this respect - believe me - there will be other times where I I will really need to lower the level of usage of language.
