Seagate Technology ST318405LW hard drive specifications

Seagate Cheetah 36XL 18.4 GB SCSI Ultra160 (16-bit)

Seagate Cheetah hard drive provides industry-leading performance for the most demanding applications, workstations, network file servers, and enterprise servers. If you are looking for truly superior performance, the Cheetah will not disappoint you. With stated reliability and excellent performance, how can you possibly go wrong? The Cheetah has received Seagate's "AV Professional" stamp of approval, which means that Seagate has tuned this drive to meet the requirements of today's most demanding audio/video applications. It features embedded-servo technology to eliminate the need to perform periodic recalibration, which slows down data transfer, making this drive ideal for AV applications. Embedded-servo technology gets rid of data interruptions that cause dropped frames in video applications. The Partial Response Maximum Likelihood (PRML) technology keeps data clear from background interference and allows Seagate disk drives to increase arial density (disk capacity), boost transfer speed, improve yield through the drive's ability to self-calibrate and lower disk noise.
