Objective According to the characteristics of digital medicine and the demands of digitized management in hospitals, we established a storage system that is affordable, highly expandable, and reliable. Methods The multi personal computer storage system (MPCSS) was constructed using hardware and software. The image data were archived from major servers to storage personal computers (PCs) by using Neusoft-picture archiving and communication system (PACS) and backed up on storage PCs. We simulated data loss on storage PCs and then restored the data. We also expanded the storage system to enlarge its capacity. Results The average transfer rate from MPCSS was 27.7 MB/s, and the average cost for this system was $74/GB. In the testing stage, only 6 of 187 instances of data retrieval (from 100 patients) failed. Conclusion The MPCSS is much less expensive than other high capacity systems or devices. It is feasible and suitable for digital image storage.
