Don’t know if there is anything “standard” per se.
On a higher end, there are enterprise class SANs and NASs like EqualLogic that automate everything and make it a snap to do expand, migrate, replicate, do snap-shots, thin-provision, etc. Super-cool stuff for geeks. Expensive: $20-40K for a 24TB box, and that’s just to start with. Nearly infinitely expandable. While performance is limited to dual bonded 10GBe per box (I believe), there are things such as SSD-based caching that’re transparent to the application.
These things aren’t designed for video (i.e. sustained throughput) but for enterprise IT, i.e. it’s all about latencies and transactions per second.
On the lower end you have to choose performance vs. convenience and automation. Performance-wise, nothing beats DAS (SAS 6G with a good RAID controller, specifically); has decent expandability features whereas you can add more boxes and expand existing volumes without any downtime. Attach it to a server and share.
For convenience (on the low end), it’s NASs like QNAP and Synology. Performance is not scalable and is limited to line speeds on available ports; expandability via USB or eSATA ports; some may offer replication.
Lastly, there are performance-oriented video-specific NASs such as Space from GB-Labs that can achieve pretty remarkable feats in terms per-port and aggregate throughput up 700MB/s on up to 10 ports with 10GbE, They start at about $20K.
Does this (sort of) answer your question?
