[Graeme Nattress] “No need to RAID unless you really want to.”
ecca2323-
There’s many advantages to having a RAID. A RAID comes in handy when you can take advantage of redundancy. You can afford to totally lose a drive, keep working, keep all of your data, and sometimes, rebuild the redundant drive in the background while continue to edit. Graeme is right, it is not absolutely essential if you are working in the DVCPro HD codec, but there are advantages. It really depends on your workflow, how much editing you’re doing, if you edit onsite (ie physically move your drives around a lot on airplanes) and how fast your deadlines approach. Buying a more expensive raid will not only gain performance, but it might just buy you piece of mind as well. I know it has me. This means that whatever you choose, you must look for RAID3 or RAID5 capability. the best ones work with a dedicated hardware controller and an HBA (host bus adapter), but some people have luck with SATA Raids. I got in early on the SATA Raid game and got out about 6 months later after I almost lost a job due to lost data. I then went with a prebuilt, preconfigured RAID and have not looked back since. My situation is unique in that I often edit onsite and have to put my drives underneath an airplane and subject them to the likes of the Transportation Security Administration. If you are looking for external fibre channel raids, also look into Huge Systems or Medea products. Both companies have forums on this site.
Good luck in your decisions and don’t forget to have fun.
