Question about disk i/o impact with multiple tuners

[sashimi]

I was wondering if disk i/o contention can impact quality in multiple tuner situation ? After I installed the 2nd tuner (PVR 350) I think I am noticing a bit of stuttering, at least over my home LAN. Is there a way to assign different recording locations (disks) to different cards ? Or is it not an issue ?

Sage requires the recording drives to be formatted with 64k stripe size..... When they are not formatted to 64k, you will get stutters....

Also, for reference, I have 10 tuners recording to 3 320GB drives in RAID 0 and it barely hits them... 10 streams at 20Mbps is 200Mbps or 25MBps, most modern HDs can run in the 60-150MBps range

hmm.. now i do remember seeing that recommendation in the manual. will have to try to empty up and reformat the drive.

You can use a program like Partition Magic to resize the drive but if you are going to buy a program to do that then why not just by an external drive copy the files and then re-format. Then you have the external drive as well!
