Hard drive performance is essential to capture video so system settings should
be tuned at best. The main benchmark is AuxSetup from VirtualDUB
because it's a capture simulation. Windows buffering must be disabled.
Whatever settings (BIOS, IDE drivers) tested with Windows 2000, I've seen frame burst drop (2 to 5 seconds). Therefore I capture video with Windows 98se.
Here are performances measured with my computer fitted with IDE Quantum LM30.0:
| Dell Dimension 4100 - Windows 98se | Sustained write |
| BIOS A05 - no IDE driver | 3,936 KB/s |
| BIOS A06 - no IDE driver | 7,331 KB/s |
| BIOS A06 - Intel Ultra ATA Storage 6.03 driver | 23,981 KB/s |
Regarding such an improvement to 23,981 KB/s, I'm now able to capture uncompressed video in CIF format 352x288 and even 480x576 or 768x288. But file size is huge : 1.2GB for 1 minute at 20,000KB/s ! Anyway, write speed of my hard drive is no longer limit for capture.
Performance improvement is visible with Performance Test too:
We can see that i815E system fitted with Asus CUSL2 motherboard and IBM 30GB DTLA ATA100 hard drive (with Celeron 700MHz) is even better. You may download complete benchmak of my Dell computer from perftest.zip and compare with you computer thanks to Performance Test (version 3.1).
