Verbatim ADR Drive Cleaning Kit Pack Size: 1 Minimum Bulk Purchase: 5 x 1 packs (5 disks) Advanced Digital Recording (ADR) is an all-new variable speed tape technology that is ideal for power desktop, servers and workstation applications. Based on revolutionary 8-channel recording technology pioneered by Philips, OnStream™ ADR drives read and write eight tracks of data simultaneously. This technological break-through delivers exceptional transfer rates along with an unprecedented level of reliability, all at substantially less cost than competing products. Verbatim ADR Data Cartridges are available in 30GB and 50GB storage capacities, assuming a 2:1 compression ratio. High storage capacity allows users to perform unattended back up on most PCs, servers and workstations using a single cartridge. Verbatim ADR Data Cartridges bring a new level of performance and reliability to the task of server and workstation backup. The ability to read and write all eight tracks of data simultaneously allows error correction code to be distributed both horizontally and vertically. This advancement greatly improves the recoverability of data. The data integrity of ADR is 10,000 times more reliable than a hard drive and 100 times better than DDS3 or DLT tape technology. In addition to its reliability, ADR’s variable-speed, 8-channel technology delivers impressive transfer rates up to 7.3GB/hr. at relatively low tape speeds, minimizing wear and noise. For performance, reliability and the capacity to handle even the most demanding storage requirements, insist on ADR data cartridges from Verbatim. A world leader in innovative tape products for 30 years.
