Now we can start to play around with test parameters. Access time and I/O performance depend on agility, positioning speed, and head precision. But they also depend on rotation speed, as waiting times for required data (referred to as rotational latency) are shorter at higher spindle speeds. Faster speeds also mean faster sequential throughput, but they require a more precise and robust drive design. Additionally, higher performance comes at the expense of recording density, and hence, capacity. Power consumption has become an additional key metric, as performance typically has a direct relation to power consumption. More power translates into greater heat dissipation, and more components at high speeds typically turns into higher noise levels. The interfaces that connect drives are evolving as well. For enterprise drives, Serial Attached SCSI (SAS) is moving to a new 6-Gbps standard this year. And for external drives, while I expect USB 2.0 to still be dominant along some eSata and FireWire drives. USB 3.0 seems poised to replace it, bringing with it much faster connections. However, I don't expect to see many drives supporting that for a while. It needs chipset support on the client PC, and that isn't yet formally in either AMD or Intel's roadmaps. * The real-life performance difference between a hard drive generation is usually faster than the one that preceded it, which helps to reduce boot and application start times. Also, let’s not forget that Windows 7 is here, and many people who vehemently stood by Windows XP when Vista was around are now considering the upgrade. Computer hardware is the physical part of a computer, including the digital circuitry, as distinguished from the computer software that executes within the hardware. Solid-state drives (SSDs) have gotten a lot of attention in small capacities for netbooks, and in larger capacities for notebooks, where their thin profiles and fast read times show some benefit. For smaller capacities, around 16GB or less, they can compete with hard drives on price, but for larger capacities they are significantly more expensive. Still, we're seeing more of a push for tiered storage, where data is split either manually or automatically among SSDs (for the most immediately needed data, often used almost like a cache), fast Fiber Channel drives (which are typically smaller capacity than traditional drives but faster, and store frequently used data) and traditional SATA-based drives (which are typically smaller capacity than traditional drives but faster, and store frequently used data) and traditional SATA-based drives (which are typically smaller capacity than traditional drives but faster, and store frequently used data) and traditional SATA-based drives (which are larger, and used for information that isn't used quite as often, but still needs to be changed and so is stored on hardware devices such as read-only memory (ROM) where it is not readily changed (and is therefore "firm" rather than just "soft").
