Abstract
A device for data compression includes a processing unit, a temporary memory, and a storage device. The temporary memory is used to temporarily store data to be compressed. The storage device includes multiple physical blocks. Each physical block has a same volume size. The processing unit compresses the to-be-compressed data, generates compressed data, and stores the compressed data into one of the physical blocks. The processing unit compares a data size of the compressed data and a volume size of one physical block, and when the data size of the compressed data is smaller than the volume size, the processing unit stores remnant data into the same physical block as the compressed data stored in, wherein the total data size of the remnant data plus the compressed data is equal to the volume size of the physical block both are stored in.
