TOSHIBA MK1234GAX 120GB

Introduction

Toshiba says they are the undisputed leader in small form factor 2.5" HDDs.  Well, they recently launched a 200GB SATA 2.5" HDD, skipping the 160GB category completely.  Furthermore, they have not offered any 7200 RPM drives either.  But that aside, we are going to look at their MK1234GAX drive in this article.  Perhaps a closer look at this product would confirm their claim in the small hard drive business.
