# Shared Storage vs Cloud: Why Studios Need Local Media Infrastructure
The cloud is everywhere. Every software company is selling you “cloud-based solutions.” Don’t fall for it when it comes to media production infrastructure.
Here’s the reality: most studios are building their post-production pipelines on cloud storage and services, thinking they’re getting scalability and flexibility. What they’re actually getting is latency, bandwidth bills, and dependency on internet connectivity. For live streaming and high-frequency content production, that’s a disaster.
The studios that are thriving—especially those doing multiple shoots per week—are building local shared storage infrastructure instead. Here’s why that’s the right call.
The Bandwidth Problem No One Talks About
When you’re editing a 4K RAW file from cloud storage, you’re not just dealing with storage. You’re dealing with real-time streaming of multi-gigabyte files over your internet connection.
Let’s do the math:
- 4K RAW file: 10 GB/min (typical)
- Cloud editing: 100 Mbps download speed (fast residential internet)
- Time to download 10 GB: ~15 minutes for ONE MINUTE of footage
- Same 4K RAW file: 10 GB/min
- Local network (10 GbE): 1,250 MB/sec (1.25 GB/sec)
- Time to stream from shared storage: Real-time, with zero buffering
- 5 clients × 100 GB per client = 500 GB per month
- Cloud storage (AWS S3): ~$11.60/month
- Data egress (AWS S3): 500 GB × $0.09 = $45/month
- Video delivery (CloudFront): ~$50-100/month depending on streaming
- 10 GbE network infrastructure: One-time ~$3-5K, lasts 5+ years
- Storage hardware (88TB-528TB options): One-time ~$15-30K, lasts 5+ years
- Electricity & maintenance: ~$100-200/month
- Total cost spread over 5 years: ~$200-400/month
- Uptime: If AWS has a regional outage, your studio stops
- Performance: If they’re doing maintenance, your speed tanks
- Data residency: You don’t know exactly where your client’s content lives
- Security: You’re trusting their security practices
- 88TB to 528TB depending on studio size
- 10/25/100 Gbps network connectivity
- NAS + SAN architecture (both block and file storage)
- Built-in RAID with automatic failover
- Indexing and tagging system (metadata management)
- Proxy generation (creates edit-ready copies automatically)
- AI auto-tagging (finds content by keywords, visual recognition)
- Full NLE integration (works with Premiere Pro, DaVinci Resolve, Final Cut Pro, After Effects)
- Watched folder automation (copy to shared storage, triggers transcoding)
- Scheduled backups to cloud or LTO (local backup, optional cloud backup)
- Automatic proxy generation (you edit proxies, final export uses originals)
- File replication and redundancy
- Proxy download for remote editors (download lightweight versions to edit at home)
- Automatic relinking when proxies are replaced
- Maintains folder structure and project organization
- Works over standard internet (only downloading proxies, not full resolution)
But here’s the hidden killer: that’s if your internet stays stable. One hiccup and the playback stops. One interruption and your edit disconnects.
Now compare that to local shared storage:
The difference isn’t just speed. It’s the difference between “we can’t do real-time editing” and “seamless 4K editing workflows.”
For studios that are doing post-production as a service (editing client content, color grading, VFX), this isn’t theoretical. This is your entire business model.
The Bandwidth Bill Nobody Plans For
Let’s talk about money.
If you’re working with multiple clients per month, each with 50-100 GB of raw footage, you’re moving terabytes of data monthly. Cloud storage providers charge you both ways: for storage AND for data egress (downloading files).
Here’s a typical scenario:
That’s $100-150/month in cloud bills just for normal operations. Scale to 10 clients and you’re at $300+/month.
Now add a disaster recovery system (2x storage, geographic redundancy, automatic backups), and cloud costs become a serious line item—often $500-1000/month.
Local shared storage has a different cost structure:
That’s infrastructure you own, with no surprise egress bills, no vendor lock-in, and no dependency on your ISP’s reliability.
The Control Problem
When your media infrastructure lives on someone else’s cloud, you have zero control over:
With local shared storage, you control every layer. Your storage appliance sits in your studio. Your network is your network. Your backup process is your process.
For studios handling client content under NDAs or contracts with data residency requirements, this matters legally. Some clients won’t let their content live on AWS. Some contracts explicitly require on-premise storage.
The Infrastructure: Shared Storage for Studios
If you’re convinced (and you should be), what does this actually look like?
For studios like E4, the infrastructure is:
1. Shared Storage Appliance (examples: Studio Network Solutions EVO, Facilis TerraBlock, ATTO)
2. Media Management Software
3. Automation Layer
4. Remote Access
The beauty of this setup: local teams get real-time performance. Remote teams get lightweight proxies they can edit anywhere. Your automation handles the heavy lifting (transcoding, backups, indexing) overnight.
Why This Matters for Live Streaming
Here’s where E4’s use case gets special.
If you’re doing live streaming and post-production from the same studio, shared storage becomes your production backbone. Here’s the workflow:
1. Stream ends → Media files land in watched folder on shared storage
2. Automation triggers → Files are indexed, proxies generated, backups started
3. Next morning → Your editors have everything ready: organized, tagged, proxy versions waiting
4. Edit at full speed → No cloud latency, no buffering, no bandwidth bills
5. Deliver to client → Export from shared storage, 10GbE network speed
Compare that to cloud:
1. Stream ends → Upload to cloud (2-4 hours for large files, if upload is fast enough)
2. Wait overnight → Cloud processes files (delayed automation)
3. Next morning → Download proxies to edit (another 1-2 hours)
4. Edit slowly → Streaming files from cloud, buffering, stuttering
5. Deliver to client → Download from cloud, upload to delivery platform (hours of waiting)
The difference is measured in days of lost productivity per month.
The Timeline
This isn’t a “future state” problem. Studios are building this now.
The hardware is mature. The software is proven. The ROI is clear.
For a studio doing 5+ projects per month, shared storage pays for itself in bandwidth and efficiency gains within 2-3 years. After that, it’s pure profit—and better workflows for your team.
The Decision
Cloud storage is perfect for archival, backup, and geo-redundancy.
Local shared storage is essential for active production workflows.
The studios thriving in 2026 use both: local storage for speed and control, cloud for backup and long-term archival. That’s the hybrid approach that works.
If you’re still purely on cloud storage for active production, you’re paying too much and moving too slow. Time to reconsider.

Next step: If you’re averaging 100GB+ of content per month, it’s time to evaluate shared storage. Get a quote. Run the numbers. You’ll likely find that the upfront investment in infrastructure saves money and speed within 12 months.
The studios investing in local infrastructure now are the ones that’ll dominate production in the next few years.
