With almost twice the capacity of DDS3 format, the LaCie DDS4 drive provides a compact, cost-effective solution to the backup storage needs of data intensive systems. The 2.4 MB/s native data transfer rate provides a capacity to transfer rate ratio of 10, 000, making it possible to meet the requirements for a shorter backup time. ??The Super Head Cleaner is incorporated within the design of all LaCie DDS drives. This is like a small brush which cleans the heads automatically after every 15 minutes' use, reducing dramatically the number of errors related to head clogging.
