The hardware of a computer is infrequently changed, in comparison with software and data, which are "soft" in the sense that they are readily created, modified or erased on the computer. o $165.99 Personal computers, the computer hardware familiar to most people, form only a small minority of computers (about 0.2% of all new computers produced in 2003) Market statistics. 15 Years of Hard Drive History: Capacities Outran Performance: Five different drives between 1991 and 2006 compared * (Likely) lower noise levels * Higher performance o $189.00 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 larger, and used for information that isn't used quite as often, but still needs to be accessible). And of course, many people are still archiving to tape. Other features getting more attention are replication, snapshots, and as always, better management tools. But the push toward Flash storage has hurt the market for the smallest hard drives. Only Toshiba and Samsung make 1.8-inch drives, with Toshiba seemingly most committed and now shipping a 160GB drive. (It's no surprise that Apple's largest-capacity iPod is also 160GB.) But in part because 1.8-inch drives have been slower than traditional 2.5-inch drives, they haven't seen as much use in notebooks. Instead, the vendors seem more focused on 2.5-inch drives, with Seagate introducing a 500GB 2.5-in drive that's only 7mm thick. * Deskstar 7K2000... All three models were released in 2005.
