2000 CD's x 20 Songs/CD x 10MB per Song / 1024MB = 390GB's.
You won't need the extra capacity of Raid5 for sure. Raid 1 is more than sufficient.
shrugs It is if you think it is.
I don't, but I'm not an audiophile that can hear those 3ms of silence before or after a song because the $15 CD ripper hasn't quite manage to take the right 50 samples either side of the audio track.
What "drivers" are these that you speak of. You'd search far and wide to find any CD drives that aren't well supported by the standard atapi drivers provided in windows 95 & upwards. If you are speaking of particular "audio ripping programs" from plextor .. you'll have to research - all standard Audio ripping programs work fine on standard atapi cdrom drives using windows standard atapi cdrom drivers.
No. A high speed dual core (rather than a quad core) will be significantly faster for audio encoding, unless you are ripping 4xCD's simultaneously, in which case your HDD & RAM will be the limitting factor.
The only reason any desktop PC could use a quad core is if you are running a server (with lots of workload), or are a serious video encoder, or you run other incredibly CPU-heavy tasks that you have researched and are aware that they use more than 2 simultaneous worker threads.
A 450W power supply is absolutely minimum these days. CPU's chew up a good 75W, and Video cards chew up 75W for a mid-range card - there's 1/3 of your rating right there.
HDD's use approximately 8W each, but can peak at 20W when starting up. Similarly optical drives can chew up 20W each.
Also be aware that Power Supplies don't run efficiently when over 80% capacity, and while it's rated at 450W ... you will find that there is a breakdown of that power rating dedicated for each of the 5V and 12V sections, and you don't want to stress either of those rails. A little homework is required. A 550-600W PSU is recommended if you don't want to do the homework and aren't building a serious gaming machine.
Raid 1. You're only using 1/3 of your 1TB HDD ... direct mirroring of the single drive is more than adequate. Raid 5 is overkill, unless you want to burn money. Raid 0 is striping, and provides NO data security at all.
Buy a good quality 64GB SSD for your computers main/boot drive (Check out the HDD/SSD forum for current recommendations - there's lots of crap out there), and use the RAID1 1TB drives for backups/storage, or even buy an independant NAS with RAID1 and have it totally separate from your main PC.
