I'm looking to add a few more harddrives to my system. I already have 4, but I might take 2 of those out and put their contents on a partition or something. Who knows. Anyway, I was looking at a few harddrives on Newegg, and always having been partial to Western Digital, they were the first once I looked at. This one immediately caught my eye, for obvious reasons: http://www.newegg.com/Product/Product.aspx?Item=N82E16822136344 2TB WD Caviar Green. Now, before I hear you say it, I won't be using these harddrives as my installation drive. I MIGHT install games to it, maybe, but probably not. These will be used for storage, for the most part. My main concern here is that I'm reading a lot of bad reviews (along with a lot of good ones) about these 2TB drives and I'd probably do better to hold off on those for a while until they stabilize. I also came across this one though: http://www.newegg.com/Product/Product.aspx?Item=N82E16822136284 1TB WD Caviar Black. Tons of great reviews about this drive and at only a little more than half the price of the 2TB, it might be worth it. And finally I'm thinking I might replace my installation drive (which is actually a partition of a 500Gig Samsung drive) with a VelociRaptor. I don't need anything large or whatever for my installation drive, just fast: http://www.newegg.com/Product/Product.aspx?Item=N82E16822136296 150GB, 10,000RPM. This should be perfect. Along with the fact that it's the 5x winner of the customer choice for internal harddrives, it sounds pretty solid. So the main thing I need is opinions, which of those 2 large capacity drives hould I get and is it worth the money to get the Raptor drive for increased performance? ALSO, I need a little help with something else. I have a 500W Antex Earthwatts PSU. It's held perfectly solid since I've had it, never an issue with it. I'm wondering what adding more harddrives will do to it though. Like I said I'll probably remove the 2 smaller harddrives I have (a WD 200GB IDE, and a Maxtor 40GB IDE) and move their contents to either a folder or a partition of another drive. Then I plan on replacing the 40.7GB partition of the 500GB Samsung SATA drive, which is my installation (C partition, with the 150GB VelociRaptor, then I want to add either 1 or 2 of those 1TB Caviar Black drives, for a total of either 4 or 5 harddrives. MY question is can a 500W PSU handle 5 harddrives, a PCI-E16x video card, 2 (internal) optical drives, an AMD Athlon 64 X2 6000+ CPU, and 5 case fans...or will I probably have to upgrade before long? I'm sure if I just remove those 2 drives and add the velociraptor and the caviar in there it won't make any difference at all, since I'm still at 4 harddrives, but I still wanna know.
