2nd hard drive Tech question.

Hello everyone;

This is more a technical question rather than a editing question.

I have a hp a262n 2.8ghz it came with an ultra dma 160gb hard drive but I realized after I purchased it the hd was only a 5300rpm. (althought it still seems to work well with ms3 even on 2 hr wedding videos)

I just purchased a seagate 160Gb 7200 rpm 8mb buffer. The question is should I make the 7200rpm my slave drive to store video only and leave the 5300rpm as the primary to run windows xp and ms3 or go the other way around and transfer all my data to the new drive and put the video on the slower drive.

Thanks for all the help in the past.

Ralph

Use the external drive for your video files. Leave everything else where it is already. You certainly don't want to copy anything essential to your external drive because of the chances that drive may become unsable (gets dropped, left at home, the cable breaks, etc.) It's bad enough if you lose your video files, but at least you can recapture them or re-render them. You have plenty of room on your internal drive so keep everything else there.

I have a related question. What is the experience out there between using an USB2 vs 1394 connection. My drive can be use both connections so is one faster than the other? I put my video files on the external 7200 rpm drive but I still experience some stuttering video (especially during pans) when I print to tape. I am running a 2.4 GHz CPU with 512 Mb of memory. Will putting more memory in help?

Use 1394 firewire whenever possible. no question.

Firewire is about 15 times faster than USB

Is 1394 that much faster than USB 2.0? Or are you comparing to USB 1.1?

Sorry you are right, we are talking about 2.0

USB 2.0 transfer rate is up to 480Mbps (megabits per second) compared to USB 1.1 devices, which transfer at speeds of 12Mbps.

Firewire is up to 1.6 Gbps or 1600 Mbps which is 3.3 times faster than USB 2.0

Electomen,

Uh, I don't where you got the 1600 Mbps figure from, but Firewire's transfer rate is generally accepted to be 400 Mbps. There is a new version of Firewire called Firewire 800 (or 1394b) that operates at 800 Mbps.

However, in spite of USB 2.0's slight rated speed advantage, Firewire is considered faster in practice (due to Firewire's peer-to-peer bus topology).
