Product Overview
The FUJITSU MAW3147NC is a 147 GB enterprise-grade 3.5-inch Ultra320 SCSI hard disk drive with 10,000 RPM spindle speed and 8 MB onboard cache. This legacy storage hardware delivers reliable persistent data storage for industrial workstations, DCS operator stations and legacy server platforms, resolving storage compatibility issues faced when maintaining older automation infrastructure. System technicians, plant maintenance teams and industrial spare part specialists working with FUJITSU storage hardware rely on this drive for stable boot function, historical trend archiving and application program storage. Equipped with fluid dynamic bearing motor technology, the unit supports continuous 24/7 operation and serves as a vital drop-in replacement for ageing SCSI storage in long-running process control environments.

Key Functions
- High-Speed SCSI Data Transmission: The Ultra320 SCSI interface supports up to 320 MB/s burst transfer speeds, enabling fast loading of control software and rapid retrieval of historical process logs. LVD and single-ended compatibility supports connection to legacy host adapters without signal conversion hardware.
- Continuous 24/7 Enterprise Storage Operation: Fluid dynamic bearing design reduces vibration and mechanical wear, stabilising performance under extended runtime. Optimised error correction and automatic bad sector management prevent gradual data corruption during long-term use.
- Persistent Industrial Data Archiving: Provides reliable storage for control system operating systems, HMI runtime files, alarm logs and historical trending data. Consistent read/write performance ensures uninterrupted data recording for process audit and equipment diagnostic requirements.
- Standardised SCA-2 Mechanical Compatibility: The integrated 80-pin SCA-2 connector fits direct hot-swap drive caddies commonly deployed in industrial control cabinets. Uniform physical dimensions simplify spare replacement without cabinet or backplane modification.
