HTS545050A7E380 Overview
With 7mm ultra-thin hard drives all the rage, Hitachi aims to blast one out of the park with its new 500GB single-platter Z5K500 – that’s right, 500GB on a single platter. Getting to this higher capacity in such a slim package has been a big deal for drive manufactures, since in the 7mm drive space you are limited to a single drive platter, instead of two in a 9.5mm drive or three in a 12.5mm drive. While capacity might be the biggest selling point of this drive, it is also important to see how well it does in the performance category.
