Tom's Interactive 3.5" Hard Drive Charts compare low-level as well as application performance of more than 40 popular hard drive models. The charts include all popular 3.5" desktop drive manufacturers such as Hitachi, Samsung, Seagate and Western Digital. They list UltraATA and Serial ATA interfaces, 7,200 and 10,000 RPM drives, and capacities between 36 GB and 1000 GB. 15 individual benchmark categories analyze read and write throughput, interface performance, average access time, Windows startup performance and several I/O access patterns that are imperative for server and workstation scenarios. Two comparison features make our Hard Drive Charts unique on the Internet: The Cost per Gigabyte calculation and the Price/Performance Index, which relates performance, capacity and cost. Prices are updated daily using the latest price information provided by TG Stores.

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.

This page is updated on a regular basis and provides a unique resource for everybody who is looking for a desktop hard drive - whether it is for home or for business use. Our service allows for interactive performance comparison, real-time price/performance and costs per Gigabyte analysis.

Tom's Interactive Enterprise Hard Drive Charts compare high-end server/workstation hard drives used in enterprise-class systems. The 15 benchmarks we used as a testing platform are the same as the ones featured in the other HDD Charts, but the interpretation of the data is different in the enterprise segment: Servers often depend on maximum I/O performance rather than on raw throughput. Of course, you can also check various other criteria: read and write throughput, sorted by average, minimum and maximum, access time, interface performance and four I/O benchmark patterns. You will find most of the popular enterprise hard drives made by Fujitsu, Hitachi and Seagate; all using either Ultra320 SCSI or SAS interfaces. Then there is the price/performance index which helps you select a particular drive, as it relates performance and capacity to cost of drive. If your company requires a large number of hard drives, this feature will enable you to make an informed and budget friendly decision.
