What system resources are being used when ripping a DVD/BluRay disc?

[SetoTitan]

I'm looking at buying a new PC that I'll use in large part to rip my DVD/BluRay collection. As such I'm trying to understand what's important when ripping a disc, is it the GPU, or CPU speed, memory, disk read/write speed? Obviously I'm sure each of the aforementioned plays some part, however I'm trying to follow what resources are being used when ripping a disc.

Just ripping doesn't require much. Just a fast blu-ray drive and a HUGE hdd for blu-ray rips.

But do you want to shrink/reconvert your video?

Yeah you make good point, it's not the ripping that will be intensive it's the encoding. I'll be using Handbrake to encode to MP4.

CPU speed and number of cores are the most important hardware considerations when converting with Handbrake. The X264 encoder is fairly well optimized for multithreaded operations, so get a quad core cpu at least.

I have a couple of Pioneer BDR-209's which are the fastest I've tried for ripping my BDs to a hard drive for backup.
It's too hard on the drives to convert directly. I use AnyDVD HD running in the background for decryption.

I use 1.5TB WD hard drives. For converting to MKV/AC3 video, I have a AMD FX-8350 8 Core CPU 4.2Ghz CPU.
This information is in my Computer Details.

Most times I use RipBot for the MKV conversions, sometimes Vidcoder. Both can batch convert from the HDD files.
It takes about 2 hours or a bit more for each conversion, but I like the quality.
I convert to a 8GB MKV for convenience for secondary backup to BD data discs. Primary backup is to my video server for playback.

For DVD conversions, also to MKV/AC3, I just use VidCoder and batch them. Takes about 20 minutes for this conversion.
I use CQ settings of 18.5 and constant framerate. Video filters of Detelecine and Decomb. Most everything else at default.
I end up with file sizes of 1GB to about 3GB, depending on the source DVD.

In my system, the GPU doesn't have much to do with the conversions. RAM either. I use about 2 - 3 GB RAM for encoding MKV,
but it does use all 8 cores at close to 100%.
