The full-sized model stores media on a built-in hard drive, while the smaller iPod nano and iPod shuffle use flash memory. As a music jukebox application, iTunes stores a comprehensive library of the user's music on their computer and can play, burn, and rip music from a CD. 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. Devices in the iPod family are designed around a central scroll wheel (except for the iPod photo). Most computer hardware is not seen by normal users. The iPod is currently the world's best-selling digital audio player, and its worldwide mainstream adoption makes it one of the most popular consumer brands.Users typically only hear about advances in the hard drive vendors see no slowdown. o $159.99 Drive makers have been talking about new technologies for many years, but so far PMR has continued to scale dramatically. Manufacturers typically can now store 320GB on a single 2.5-inch platter, which is why 640GB drives are a common size. A year from now, we may see that grow to about 500GB per platter, with a four-platter drive reaching 2TB. This, too, should grow. 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 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. This year's big news was the introduction of 2TB 3.5-inch drives and 1TB 2.5-inch drives, respectively the top-end capacity for desktops
