LTO-4 1840 specifications

The HP LTO-4 1840 tape drive is a pivotal data storage solution shaped by the need for efficient, high-capacity tape storage. As part of the Linear Tape-Open (LTO) technology series, this tape drive was designed to cater to the growing demands of businesses for secure and reliable data backup, archiving, and recovery solutions.

One of the standout features of the HP LTO-4 1840 is its impressive storage capacity. Each cartridge can hold up to 800 GB of compressed data, which is ideal for enterprises needing to manage large quantities of information. When dealing with uncompressed data, the capacity is 400 GB, showcasing significant increases over previous generations. This advancement increases efficiency and reduces the frequency of tape changes, streamlining the backup process.

The LTO-4 technology also introduced a notable enhancement in transfer rates. The HP LTO-4 1840 boasts a native data transfer rate of 120 MB/s and up to 240 MB/s compressed. Such speeds provide businesses with faster backup and restore operations, minimizing downtime and enhancing productivity.

In terms of compatibility and flexibility, the HP LTO-4 1840 is backward compatible with LTO-3 and LTO-2 tape formats. This backward compatibility ensures that organizations can seamlessly transition to newer storage technologies while still utilizing their existing tapes, protecting their investment in legacy data storage systems.

Data durability is another hallmark characteristic of the HP LTO-4 1840. The tape drive employs advanced error correction and data integrity technologies, ensuring that stored data remains intact over long periods. Additionally, the drive utilizes a robust mechanism to reduce wear and tear on tapes, extending their longevity and reliability.

Security features are also embedded in the LTO-4 framework, including AES 256-bit encryption, which secures stored data and ensures compliance with various regulatory requirements. This encryption capability protects sensitive information from unauthorized access during the backup process.

The HP LTO-4 1840 tape drive is optimized for a range of environments, including small, medium, and large enterprises. With its combination of high capacity, fast transfer rates, robust security features, and compatibility with previous generations, this tape drive remains a reliable choice for organizations looking to safeguard their critical data assets effectively.
