2.6 Data Compression

Data Compression is a way to increase capacity on a storage device. Compression ratios are normally specified to be 2:1, meaning that it is possible to store twice as much data on the tape as without data compression. However, the compression rate is depending on the type of data, e.g. ordinary text files can be compressed in a much higher rate than program- and picture files.

There are two ways to compress data, hardware compression and software compression. Hardware compression means that the data compression is done by the electronics in the storage device. Software compression means that an application program in the host computer is compressing the data before it is sent to the storage device. Hardware compression is much more efficient, and works much faster than software compression.

The Tandberg LTO HH tape drives uses SLDC hardware compression to compress data. This feature is enabled per default but the user may turn off data compression through the application software.

Note:

If the data are compressed by software in the host computer, and then sent to a device that does hardware compression, the data have a tendency to expand instead of being compressed.

Be sure to turn the software data compression off if using the Tandberg LTO HH - which has embedded hardware compression.

LTO-1 HH, LTO-2 HH, LTO-3 HH specifications

Tandberg Data has long been recognized as a leading provider of innovative data storage and backup solutions, and their tape drives, specifically the LTO-1, LTO-2, and LTO-3 Half Height (HH) models, represent a significant advancement in data storage technology. These systems are designed to meet the demands of modern data management, balancing capacity, speed, and reliability.

The LTO-1 HH, introduced in 2001, marked a groundbreaking step in the linear tape-open (LTO) technology. It offered a native storage capacity of 100 GB and a compressed capacity of up to 200 GB. The tape drive featured a data transfer rate of 20 MB/s, allowing for efficient backup processes. One of the key technologies in the LTO-1 was its use of ultral Linear Tapes, which helped in maintaining the integrity of data over extended periods. The built-in data compression capabilities also contributed to the efficient storage of large volumes of data, making it suitable for small to medium-sized businesses.

Building on the success of the LTO-1, the LTO-2 HH was launched, significantly enhancing performance with a native capacity of 200 GB and a compressed capacity of up to 400 GB. The data transfer rate improved as well, reaching 40 MB/s. The LTO-2 introduced the concept of WORM (Write Once, Read Many) technology, which added a layer of security by ensuring that data could not be tampered with after being written. This was particularly important for industries requiring regulatory compliance. Enhanced error correction and data integrity features were also hallmarks of the LTO-2, ensuring reliable long-term data storage.

The LTO-3 HH followed suit with even greater advancements, providing a native capacity of 400 GB and a compressed capacity of 800 GB, along with a data transfer rate of up to 80 MB/s. Its improved track layout and data encoding methods further enhanced performance and reliability. Additionally, LTO-3 introduced the partitioning feature, which divided the tape into virtual partitions for more efficient data management, allowing users to access data faster. The data encryption capabilities introduced with LTO-3 provided enhanced security, protecting sensitive data during backup and storage.

Together, these Tandberg Data LTO tape drives showcase a remarkable evolution in data storage technology, offering robust solutions that cater to businesses of all sizes. Their reliability, security features, and substantial data capacities ensure that organizations can efficiently manage their growing data storage needs in an increasingly digital world.
