OT: Computer Questions I was doing a HF run last night, using User Switching (XP), and my computer was running painfully slow. I finally got through it, and looked at the specs for my PC. I got to thinking about it, and realized I bought it almost 5 years ago. P4 1.9GHz 1GB RAM (I added to the original about 6 months ago) 80GB HD (how do you tell if it's serial or parallel)? After looking at the HD, I realized that 79.2GB were full. Would explain some of my slowness last night. Anyways, the gist of this is I am going to get a new (additional) HD, but don't know how to tell if I need a serial one, or parallel? Does it matter? Is it dictated by the mother board? Any help is appreciated. EDIT: I looked online at my local store, and saw this. Sounds like a good deal to me. Is it? EDIT2: @nebux: #DOH!:duh: I forgot to mention that I have a ton of digital pictures (mostly of my little girl), so this second drive will most likely be mostly dedicated for picture storage. EDIT3: Is the XMB buffer, essentially RAM on the HD? A temp storage space for files in use?
