Working with partitions

[perdomot]

I've got my raid 0 array divided into 4 partitions with one partition dedicated to vid capture and another for where I store encoded video. I was wondering if it makes a difference in speed working with two partitions rather than just one. Would it be faster to store and encode video on just one large partition? Thanks.

It's generaly best to capture to another physical hard drive. The raid is fast enough by itself, so I do not see any benefit of creating partitions as they are really virtual drives, not physical. I have a 250 GB raid 0 and have captured MPEG2 and uncompressed AVI and have had no problems.

I can see you running into some issues if your capture is running long and you run out of space on one of your partitions. Really, I only see a downside to having the multiple partitions.

Since raid treats the two hard disks as one, I thought reading from one partition and writing to another at the same time might be incurring a performance hit. Does the raid 0 compensate enough for the hit?
