A modern world is hard to imagine without a wealth of media content, including audio and video data. It seems like just yesterday that a collection of MP3 files was the pinnacle of dreams. Today, 4K video files are considered quite ordinary. All this media content needs to be created, stored somewhere, and then made accessible. Modern data storage systems (and Qsan <\/a><\/noindex>indeed) are ideally suited as one of the main tools for working with content.<\/p>\n

Of course, the main consumers of capacity and bandwidth in communication channels are video data. The constant increase in video frame resolution raises the requirements for hardware. As a result, equipment that was relevant yesterday quickly becomes outdated. A typical transition to the next generation of resolution leads to a fourfold increase in the number of points in the frame. Consequently, just one minute of uncompressed 8K video takes over 100GB. <\/p>\n

<\/p>\n

Today, professional work with high-resolution video content is no longer the prerogative of just large studios. The growing popularity of series, streaming, and high-definition television is attracting more and more players into this business. All these studios continuously generate a massive amount of 'raw' material that requires subsequent processing.<\/p>\n

It has become the norm that most workers in the content production industry are creative individuals. Among them, the primary approach to solving technical issues regarding disk capacity has been to acquire new external storage devices. Typically, these have been desktop NAS models with 2-5 drives. The choice NAS <\/a><\/noindex>is conditioned by simple and straightforward procedures for their use among non-technical specialists. The speed of operation is quite acceptable when used individually as DAS (especially when equipped with Thunderbolt or USB 3.0 interfaces). When joint data access is necessary, such a NAS (also known as DAS) can simply be connected to another workstation. <\/p>\n
