DataLocker, Inc Sentry K350 16 GB USB flash drive SK350016FE

Secure Encrypted USB Drive

The DataLocker Sentry K350 is a 16 GB USB 2.0 flash drive with an onboard keypad and digital display for hardware-based authentication. It targets organisations and individuals who require FIPS 140-2 Level 3 validated encryption without relying on host software. The drive uses a Common Criteria EAL5+ certified secure microprocessor to protect data at rest. Its ruggedised enclosure meets MIL-STD-810G and IP67 standards for extreme environments.

Upgrade From Software Encryption

This drive replaces software-encrypted USB sticks that depend on operating system tools or installed agents for protection. The hardware keypad removes the attack surface of keyboard loggers and malware on the host machine. The jump is worth it when compliance mandates physical tamper evidence and validated cryptographic modules. It also suits users who need cross-platform access without administrator rights to install drivers or management consoles.

USB 2.0 Interface Limits

The USB 2.0 interface caps sustained throughput at 190 MB/s for both read and write operations. This bandwidth is adequate for documents, spreadsheets and compressed archives but becomes a bottleneck for large media libraries or full disk images. Latency and protocol overhead reduce real-world speeds below the stated maximum. Users moving multi-gigabyte files daily will find the transfer time noticeably longer than USB 3.0 or 3.1 alternatives.
