Video editing has always placed higher demands on storage than any other file-based applications, and with today’s higher resolution formats, streaming video content demands even more performance from storage systems, with 4K raw requiring 1210 MB/sec per stream—7.3 times more throughput than raw HD. In the early days of non-linear editing, this level of performance could only be achieved with direct attached storage (DAS). As technology progressed, we were able to add shared collaboration even with many HD streams. Unfortunately, with the extreme demands of 4K and beyond, many workflows are resorting to DAS again, despite its drawbacks. With DAS, sharing large media files between editors and moving the content through the workflow means copying the files across the network or on reusable media such as individual USB and Thunderbolt-attached hard drives. That’s not only expensive because it duplicates the storage capacity required; it also diminishes user productivity and can break version control protocols. In this blog, we'll look the key differences between major storage technologies and well as general usage recommendations.
If you’ve worked in storage for decades as I have, you’ve heard all the debates about which storage works best for each step in media workflows. But one thing that’s clear is that not every step has the same storage requirements, and that some kind of tiered storage strategy is needed. With every-expanding digital asset libraries, storing it all on high-performance disk isn’t practical or cost-effective. Traditional tiered storage is straightforward: store the most active, most recently used data on fastest, expensive disk storage, and store the less active, older data on slower, less expensive storage, generally tape or lower cost disk arrays. Hierarchical storage management (HSM) software was built to automate the data migration between tiers, and make file system access transparent regardless of where the data is stored. When the primary storage filled to a capacity watermark, for example, 90% of capacity, the HSM system would find the files that were least recently used and move them to the secondary tape tier until the disk storage had sufficient available capacity. This model of tiered storage was built for business data where the focus was containing costs. Disk storage was expensive, tape was cheap, and older business data was rarely relevant except for an occasional audit. The criteria was simply performance vs cost. But media workflows don’t manage business data. Here are the 3 biggest considerations for developing a new approach to workflow storage.
