Tom's Interactive 2.5" Hard Drive Charts compare notebook hard drives. Here you will find 2.5" UltraATA and Serial ATA hard drives manufactured by Fujitsu, Hitachi, Samsung, Seagate, Toshiba and Western Digital. The charts include all popular capacities starting at 40 GB as well as listing hard drives running at 4,200, 5,400 or 7,200 RPM. 15 benchmarks help to determine application perforrmance and low-level performance, giving you all the throughput, access time, interface and I/O performance results. The 2.5" HDD Charts also include the Cost per Gigabyte calculation and our Price/Performance Index, which helps you to find the best bang for the buck. In addition, we measured power consumption of most the notebook hard drives, so you can see which models are energy efficient and which ones aren't.

Tom's Interactive Mobile CPU Charts focus on popular mobile processors, which are used in laptops and notebooks because of their increased energy efficiency. We tested nine AMD and Intel processors tested across 15 different benchmarks using Windows XP. Core 2 Duo is the dominating processor in the notebook/laptop space and AMD's Turion 64 X2 has become a budget option. However, all of these dual core processors deliver sufficient performance for mainstream applications. The Price/Performance Index relates US$ costs to the overall performance.
