In this new year season, I bought a set of desktop hardware and built a new PC. Here is the hard drive. Western Digital Caviar Blue 1TB, SATA 3 (6GB/s), 7200RPM, 64MB Cache, 3.5in. It is designed for desktop, called Desktop Blue. Largest cache in this class. Transfer Rate (Buffer To Disk) 150 MB/s (Sustained)
