Special Edition 8MB buffer HD?

[Half]

What benefits will a hard drive with an 8MB buffer have over a hard drive with a 2MB buffer.

(Everything is exactly the same except the buffer size)

Will this larger buffer have any noticable difference or help any when capturing video? I guessing the hard drive isn't the bottleneck though

An 8 MB cache will help with small file transfers. Any kind of large file movement or sustained video capture will fill the buffer, and then be limited by the write speed of the hard drive. For video capture, it depends on what you are doing. For instance, 320x240 monochrome at 30 fps is about 2.5 MB/sec. This would be a low-end webcam. A higher end webcam or camcorder might put out 640x480 24 bit color at 30 fps. This is more like 28 MB/sec. Most IDE hard drives will not do that. If you want to do professional video capture - 1k by 1k at 30 fps, 12 bit monochrome, you are talking 60+ MB/sec, and the only way to do that is stream to RAM. Really high end cameras can put out 2k x 2k 12 bit at 25 fps (200 MB/sec), which the PCI bus cannot handle. Then you have to have local frame storage and/or image processing on the framegrabber (the board that captures image data from the camera).

hey half.. the only thing that will help you attatin 640x480 and above video captures is SCSI or RAID (i prefer scsi, 10,000 or 15,000)

im an anime music video maker so ive done all the digital video research you can think of.. name it.. i probably know it
