Hi folks - after a blown fuse cut the power to my main PC the on-motherboard raid controller and my backup hard drive died. So I'm buying the core of a new PC. New CPU, motherboard, memory and hard drives. I use my PC for work and play. I need to do thinks like run a Webtrends log report on a 2 gig log file while playing MP3s, downloading a 50 meg file with CuteFTP, surfing the net with 10 browser windows open, creating big images with Paintshop Pro, having Mailwasher and Outlook receiving emails, editing sites with Dreamweaver and having Adobe Acrobat optimizing 100 4 meg PDFs. All at the same time. You get the idea. I currently have a P4 2.3 with 1 Gig ram and 1 (remaining) 180 gig drive. The PC isn't fast enough. I was thinking about getting a 64 bit athlon. But I have always found the hard discs to be the bottleneck. I have seen the Western Digital WD740GD Raptor 74GB Serial ATA 10,000rpm 8mb Cache for £100 each. A mirrored pair of these should be excellent for the OS and main apps. And I want to get another 180gig drive to mirror my current C drive (replacing the dead drive) which I will use to install games and less important apps. (I will use a second PC as a server for many of my other required files). These drives can do 'command queuing' and I need a motherboard which will support this feature. It works on Intel's ICH6 Southbridge, part of the new 925/Alderwood and 915/Grantsdale chipsets. Any suggestions as to a final configuration? Also is it difficult to setup 2 RAIDS on the same PC? And lastly I want to implement an uninterruptible power supply to avoid this in the future. Ebuyer do them for 60+VAT which is a price I can live with but I know nothing about UPS's. Any advice? Thanks folks.
