Well, i'm quickly running out of room and looking to get a new SATA HD. I have a few in mind, but can't make up my mind. I dont know if i should shell out the extra for a larger drive... or just get a 250-320 for like, $100. One side note, with the purchase of this drive, my chassis will be maxed out on space and SATA/IDE drive slots... so i'm trying to make this expansion count. Would be niice... dunno if its worth the extra money. Western Digital Caviar RE2 WD5000YS 500GB 7200 RPM 16MB Cache SATA 3.0Gb/s Hard Drive - OEM $179.99 A good midrange.
