I've been reading through the forum for ideal hard drive setup. The consensus seems to be a single SSD drive to support 4 simultaneous recording of video sources.

However, there are not much that discuss ideal setup for 12-16 simultaneously recordings. The computer is primarily used as a backup recording, recordings all video sources, and it record new files every 15 minutes. The computer will be on 24/7 and I have a script that will automatically delete the oldest recordings, to make room for future new recordings.

I was thinking of doing RAID 10 8x2TB HDD (not SSD). Is that sufficient? or is the initial consensus of a single SSD drive sufficient to support 12-16 simultaneous recordings?

Interesting that your computer are not able to do even 4 recordings. I do 4 on a single hdd (not ssd) with no problem. Maybe your graphic card is underpowered?

I know it is possible, but i want to get it right the first time. My pc is 8-core, quadro 4400, 64gb ram. What should the hdd setup be?

I can do raid 0,1,10, or 5.

I can record 7-8 multicorder tracks to a single SSD without problems. At that point the CPU runs into it's limits, the SSD could even do more.
If you record at 30MB/sec per track, a modern SSD can do 16 tracks.
If you get a 2TB SSD, you have one hour per track backup before it gets deleted.
It will need more than standard CPU power though.
