Abstract

The present invention relates to controlling a page cache memory in devices which are implemented to run both best effort (BE) applications and simultaneously real time stream applications, where the controlling is based on adapting the buffer size dynamically to these applications. The aim of the present invention is therefore to maintain the power consumption associated with storage means, especially hard disk drive (HDD), for such real time stream and best effort applications optimally.
