Savvio SCSI drives decode track 0 location data from the servo data embedded on each surface to eliminate mechanical transducer adjustments and related reliability concerns. A high-performance actuator assembly with a low-inertia, balanced, patented, straight-arm design provides excellent performance with minimal power dissipation. 3.1 Standard features The Savvio SCSI family has the following standard features: • Integrated Ultra320 SCSI controller • Multimode SCSI drivers and receivers-single-ended (SE) and low voltage differential (LVD) • 16 bit I/O data bus • Asynchronous and synchronous data transfer protocol • Firmware downloadable via SCSI interface • Selectable even byte sector sizes from 512 to 528 bytes/sector • Programmable sector reallocation scheme • Flawed sector reallocation at format time • Programmable auto write and read reallocation • Reallocation of defects on command (post format) • ECC maximum burst correction length of 320 bits • No preventative maintenance or adjustment required • Dedicated head landing zone • Embedded servo design • Self diagnostics performed when power is applied to the drive • Zoned bit recording (ZBR) • Vertical, horizontal, or top down mounting • Dynamic spindle brake • 8,192 kbytes data buffer • Hot plug compatibility (Section 9.6.4.1 lists proper host connector needed) • Drive Self Test (DST) • BackGround Media Scan (BGMS) • Data Integrity Check • Power Save • Supports SCSI bus fairness 3.2 Media characteristics The media used on the drive has an aluminum substrate coated with a thin film magnetic material, overcoated with a proprietary protective layer for improved durability and environmental protection. 3.3 Performance • Supports industry standard Ultra320 SCSI interface • Programmable multi-segmentable cache buffer (see Section 4.5) • 10,000 RPM spindle. Average latency = 3.00 ms • Command queuing of up to 64 commands • Background processing of queue • Supports start and stop commands (spindle stops spinning) 8 Savvio SCSI Product Manual, Rev. D
