The Transcend TS1TSSD420I is an industrial-grade 1TB internal 2.5-inch Solid State Drive (SSD) designed for mission-critical and extreme-environment applications. Part of Transcend's SSD420I lineup, it prioritizes hardware endurance and environmental resilience over consumer-grade peak speeds.
Core Technical Specifications

• Form Factor: 2.5-inch internal drive (7mm thick).
• Interface: SATA III 6Gb/s.
• Capacity: 1 TB.
• Flash Type: High-quality Multi-Level Cell (MLC) NAND flash.
• Sequential Read Speed: Up to 530 MB/s.
• Sequential Write Speed: Up to 470 MB/s.
• Random 4K Read/Write: Up to 75,000 IOPS / 75,000 IOPS.
• Mean Time Between Failures (MTBF): 2,000,000 hours.

Key Features

• Wide Temperature Tolerance: Operates reliably in extreme temperatures ranging from -40°C to 85°C (-40°F to 185°F).
• Industrial Endurance: Built with advanced global wear-leveling, flash bad-block management, and StaticDataRefresh technology to maximize lifespan.
• Power Protection: Includes Advanced Power Shield technologies to maintain data integrity during sudden power dropouts.
• Physical Robustness: Features heightened resistance to shock and vibration compared to standard consumer-grade drives.

Typical ApplicationsThis drive is not ideal for consumer gaming rigs or budget PC builds due to its high industrial price premium. Instead, it is commonly sourced for:

• Embedded systems and industrial automation.
• Outdoor kiosks, ATMs, and digital signage.
• Transportation and aerospace computing.
• Medical equipment and military-grade machinery.
