The Disk 36.4GB, U320, 15k / 357913-001 storage array is a high-performance, high-capacity storage device particularly well-suited for high-end systems. However, it can be used an smaller systems requiring large storage capacity. It has a formatted capacity of 2.5 Gbytes (3.4 Gbytes unformatted)* with a footprint of 452 Mbytes (format- ted/square foot). Consisting of four independent, parallel spindles connected through the SDI, the Disk 36.4GB, U320, 15k / 357913-001 offers multipath, multi-spindle throughput capa- bilities that include 4 Winchester spindles, 4 actuators, and 15 data heads per spindle. It can also be connected to any system supported by KDA50 or UDA50 Disk 36.4GB, U320, 15k / 357913-001 controllers. • Capacity (formatted): 2.5 Gbytes • Capacity (unformatted): 3.4 Gbytes Disk 36.4GB, U320, 15k / 357913-001 • Peak transfer rate: 2.4 Mbytes/s/spindle • Average access time: 32.3 ms/spindle • Single-track seek:t 6 ms • Average latency time:t 8.33 ms/spindle • Dual access: Standard • Media surfaces: 7 data, 1 servo • Sectors per track: 57 • Bytes per sector: 512 • Rotational speed: 3600 RPM • Maximum spindles per UDA50 or KDA50 controller: 4 • Spindles per array: 4 *Unformatted capacity provided for comparison purposes; only formatted capacity is user accessible in any disk device. tHardware capability only; does not reflect Disk 36.4GB, U320, 15k / 357913-001 optimization.
