Seagate Medalist Pro 9140 – ST34520N 4.55GB SCSI-3 Ultra 7200RPM 9.5ms 50-Pin Hard Drive
Description: Medalist Pro drives combine magnetoresistive (MR) heads, partial response/maximum likelihood (PRML) read channel electronics, embedded servo technology, and a SCSI-3 (Fast-20 and Fast-40) interface to provide high performance, high capacity data storage for a variety of systems including high-end desktop systems, workstations,and entry level servers. Fast-20 and Fast-40 (also known as Ultra SCSI and Ultra-2 SCSI) are negotiated transfer rates. These transfer rates will occur only if your host adapter also supports Fast-20 and Fast-40 data transfer rates. This drive also operates at SCSI-2/SCSI-3 data transfer rates for backward compatibility with non-Fast-20/Fast-40 capable SCSI host adapters. 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 selectable) Low audible noise for office environment Low power consumption Audio Visual (A/V) ready Supports industry standard Ultra
