Burn multiple dvds at once

[doubleJ]

I'm wanting to buy 2-4 dvd burners so that I can do multiple burns at once from my computer. I know nero supports burning to multiple drives, but I can't figure out how it would work. A single 16x dvd is ~22MB/sec whereas most hard drives top out at ~10MB/sec. By that calculation, a hard drive couldn't burn 1 dvd at full speed, let alone 3.
I've been looking into dvd duplication towers and have seen controllers that will burn up to 7 dvds at 16x from a single ide hard drive. The controller has 64MB of ram, but even paired with the cache from the hard drive and burners it still doesn't make sense.
I've looked inside a 16-bay cd tower and it basically looks like a 4 port controller that's branched off to 3 other groups of 4 ports.
There has to be a way to do this. I was thinking about 2 sata hard drives in raid 0, but I still can't see that being enough throughput. It shouldn't be necessary given the duplication towers are doing it with much less effort.

Uhhhh...so I don't know what kind of painfully slow HD you're using, but my seagate 7200.7 has a extended read rate of 50-60mb/s. (Bytes, not bits).

Even the ancient 10GB Maxtor that came in a P3 system reads faster than 10mb/s.

I burn 2 at once before w/o problem.. never done 3.. though i can hook up all my dvd burners and try.. but i'm too lazy.. my dvd are ide and hdd are scsi.. I never done 16x because i'm afraid of coaster.. so i burn between 2-6x

Hmmm...
Seagate 120GB, 7200RPM, 8MB
Western Digital 120GB, 7200RPM, 8MB
Western Digital 160GB, 7200RPM, 8MB
I've only broken 10MB/sec a couple of times. I can't see how a hard drive that's rated at 100mb/sec (megabits) can do 50MB/sec (megabytes). I only graduated high school, but that doesn't compute.

i dunno if this is good advice or not, but if you are going to burn multple dvd at the same time, i would go with scsi harddrives and scsi dvd burners tobe on the safe side.

ATA100 is theoretically rated at 800Mbps (megabits per second) equals 100MB/s (megabytes per second).

Here are some transfer rate benchmarks:

The 7200.8's capacious 133 GB platters enable the drive to hit a transfer rate of just under 70 MB/sec
