Abstract: With the exponential growth of data, storage technology becomes the core driving force of development of information industry, the storage system to some extent, is more important than computing and communication systems. The urgent problem of storage system is how to efficiently store data. The article describes the efficient storage technology RAID technology, data de-duplication technology, data compression technology, designs and realizes an application of efficient storage optimization characteristics in a Linux environment. The experiments show that this application realizes software RAID, removes repetitive data, improves the space utilization of the storage system, reduces storage energy consumption.

Key words: efficient storage, RAID, data deletion, data compression, storage energy consumption
