Well,
Raid 0 is fast especially on XFS filesystem... You will see the difference.
However... If one disk packs up... that's it...
As for me it is not a problem : data are not supposed to stay, I grab
frames, process, export then delete.
And if trouble happens : I rescan. Yes a pain but not dramatic.
Counterpart of XFS : it gets fragmented. So you need to look after that.
There is a lot of tools for XFS.

Maybe a redundant array on XFS liek Raid 5 or 10 as suggested. But get
your Os on a separate drive.
That will save you some big problems if a disk goes wrong.
More important than speed, I found that Raid enterprise edition of
drives are way better.

No not yet. I thought 10 000 tours and SAS will be enough. And I
hesitate between RAID 0 or 5 don't know exactly which one will be
better ...
Thanks a lot.

Did you set up your 2 drives as Raid 0, you may well have a bottle
neck there if not.
Careful that you may need a dedicated drive for your OS.

Another great bunch of thanks to Rafealla and her grandma's advises
without which i couldn't make the last work where DNxHD was not
fluid enough. So i did it with proxy editing and that was great. I
could use 6-7 video channels without any problème and render with
DNxHD version on mjpega to get HD with handbrake.
Anyway proxy is great even if you have to do everything twice at
tjhe end you earn a lot of time when you're editing.
in fact I don't understand why it's so slow. I bought recently a
second hand PC with two xeon 5460 3,1 ghz 4 cwith 6 go ram and nvdia
quadro fx4600 and two hard drive sas 10000 tours with 300 go each.
cpu is working 100% memory is saturated at 6 Gio
Tell me just if it's normal that i have to wait 6 minutes for 1 min
vidéo on background rendering with jpeg quality at 20 % ?
Thanks
