It's not so much that there are completely new technologies hitting in these areas, but some of the things that have been around for a bit are becoming more popular. Just about every storage maker offers some form of storage virtualization, making it easier to move storage from one physical location to another without the application knowing about the change. as that's the key reason for SANs in the first place. SSDs—typically very fast drives made from SLC flash and special controllers—are getting more attention, particularly in applications where fast reads can help a system handle more transactions. o $179.99 The most recent version of iTunes has video organization features. As of July 2006, the lineup consists of the 5th generation iPod, with a video player; the iPod nano, with a color screen; and the iPod shuffle. Current drives are using a technique called heat-assisted magnetic recording (HAMR), although other techniques, such as self-ordered magnetic arrays, are also being investigated. o Directron 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 TigerDirect o $165.99 * (Likely) lower noise levels 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. 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. Like many digital audio players, iPods can serve as external data storage devices when connected to a computer. This year, we're seeing more SSDs at capacities such as 64GB and 128GB, often made from less-expensive MLC memory with special controllers.
