## Buyer Intent Signals
Problems: DIY Software-Defined Storage (SDS): Using commodity hardware and open-source software like TrueNAS or Ceph to build custom storage clusters. | Traditional Scale-Up NAS Management: Continuing to manage fragmented, disparate NAS units without a scale-out architecture, leading to manual data migration.
Solutions: highest capacity scale-out NAS for media production | enterprise unstructured data storage solutions | best storage for generative AI model training | Public Cloud Native Storage: Relying on public cloud storage buckets (S3, Azure Blob) without a dedicated high-performance file layer.
Comparisons: Isilon vs NetApp for petabyte scale | OneFS vs GPFS comparison
