Western Digital WD2500JS 250GB SATA II 7200 RPM 8MB Internal Hard Drive. Western Digital hard drives deliver industry's leading performance and sets uncompromising standards with capacity 80GB and an average seek time of 8.8 ms. Higher areal density improves reliability by reducing the total number of platters and read/write heads (moving parts) required to achieve a given capacity. Additional benefits to lower head and platter counts include improved performance and reductions in power consumption, acoustic noise, and cost per MB.
