"Donno much about ... Raid one or two"  I should begin singing. I began reading wikipedia i understand that RAID 10 or 50 are may be better for long editings and RAID 0 suites more for short projects. If I understood correctly you have to have at least two backups of the rushes. One you don't touch as second backup. One you use currently to supply and store from RAID drives. One drive for the OS where stays the XML file and RAID drives for storage of the rushes and renders. Once finished and backed up you delete. Another question debated is software or hardware solution. I'm on ubuntu studio 64 10,04 ans soon on 12,04.  As I read Linux core has no problem with RAID 0 1 5 and combinations. I didn't look yet how to handle it with software. (Cheaper solution) Some hardware solutions are told easier because all in one but may be a painfull if not the "good ones" (expensive solution) What is your experience ? Le 01/05/2012 05:46, Tim Copeland a écrit : Linux RAID currently supports RAID 10 on 2 drives. Would recommend that over RAID 0 in most cases. It will give you the redundancy of mirroring with the IO of striping with as few as 2 drives. Plus none of the hassles that come with booting your OS on a striped array. The only drawback is that few distro support setting it up at install time. No biggie if you are configuring it as secondary storage, if the distro has native drive/partition management GUI's. However, if trying to set it up to install an OS on, you need to be fairly comfortable with Linux command line. Some time ago, I put together a cheat sheet for just such occasions. I can make it available if needed. On Tue, 2012-05-01 at 12:50 +1200, E Chalaron wrote: Haldun 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. cheers Edouard On 04/28/2012 04:28 AM, Haldun ALTAN wrote: 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 % ?
