UltraStar 18LZX, the third generation of IBM's UltraStar line, employs a revolutionary design to provide industry-leading performance and high reliability. IBM has made 18LZX more reliable and faster by using glass rather than aluminum disk platters and load/unload technology. Load/unload parks the recording heads off the disk platters when they aren't in use, which leads to wear reduction and better reliability and reduces power usage in standby mode.18LZX features giant magnetoresistive (GMR) advanced head technology to reach its areal density of 3534Mbits per square inch. The Cache Optimizer feature reduces access times to increase performance. All of these advanced technologies come together to create a drive that can support applications that use crisp and clear audio, high-definition and life-like video, colorful graphics and animation, and enormous databases. UltraStar 18LZX is ideal for large intranets and Internet applications, as well as digital video editing.
