Medalist Pro Product Manual, Rev. D 7 3.1 Standard features The Medalist Pro family has the following standard features: • Integrated SCSI controller • Single-ended and multimode single-ended/low voltage differential SCSI drivers and receivers • 8 bit and 16 bit I/O data bus models available • Asynchronous and synchronous data transfer protocol • Firmware downloadable via SCSI interface • Sector size 512 bytes/sector • Programmable drive capacity • Flawed sector reallocation at format time • Programmable auto write and read reallocation • Reallocation of defects on command (Post format) • 256-bit Reed-Solomon error correcting code • Sealed head and disc assembly • No preventative maintenance or adjustment required • Dedicated laser textured head landing zone • Embedded servo data rather than a separate servo data surface • Self diagnostics performed when power is applied to the drive • 1:1 Interleave • Zoned bit recording (ZBR) • Vertical, horizontal, or top down mounting • Dynamic spindle brake • Active IC terminators enabled by jumpers ("N" and "W" models only) • 512 K byte data buffer • Hot plug compatibility (Section 9.6.4.3 lists the proper host connector needed) for "WC" and "LC" drives • SCAM (SCSI Configured Automatically) plug-n-play level 2 compliant, factory set to level 1 (not user select- able) • Low audible noise for office environment • Low power consumption • Audio Visual (A/V) ready 3.2 Media characteristics The media used on the drive has a diameter of approximately 3.5 inches (86 mm). The aluminum substrate is 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 Ultra SCSI interface (also called "Fast-20 SCSI") and Ultra-2 SCSI ("Fast-40") • Programmable 1 or 3 segment cache buffer • 7200 RPM spindle. Average latency = 4.17 ms • Command queuing of up to 64 commands • Background processing of queue • Supports start and stop commands (spindle stops spinning) 3.4 Reliability • 800,000 hour MTBF • LSI circuitry • Balanced low mass rotary voice coil actuator • Incorporates industry-standard Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) • 3-year warranty
