You Thought That Data Was Cold — AI Thinks Otherwise

For years, storage teams categorized data into neat tiers:

  • Hot = recently used
  • Cool = rarely accessed
  • Cold = archive-only

Then AI changed everything.

In our latest webcast, Gleb Budman (CEO & Co-Founder of Backblaze, called out the shift:

“There’s all this data that maybe was thought to not be valuable anymore. But now suddenly it is — and you need access to it.”

Archived videos, logs, long-forgotten assets — once considered cold — are being pulled back into active workflows. Why? Because multimodal systems demand historical, diverse, and richly contextualized data.

“With AI workloads, you’re feeding massive datasets into GPUs… and latency kills performance,” Patel said.

“If you’re pulling that from cold storage, you’re adding delay at every step.”

Cold Storage Was Built for a Different Era

Cold storage had a purpose: cheap, deep, slow. It made sense for disaster recovery, compliance archives, or backups you hoped never to touch. But today’s workloads are constantly retrieving, iterating, and feeding compute. That turns yesterday’s cold data into today’s bottleneck.

Patel shared one example from the field:

“We had a media customer who needed to re-index their library after updating their asset management system. The cost and delay to pull it from Amazon S3 Glacier was so bad, they said, ‘We’re never doing that again.’”

That’s the real-world impact of treating hot data like it’s cold.

Always-Hot Isn’t Just Faster — It’s Smarter

Backblaze’s B2 Cloud Storage (an object storage service) was built around a different assumption: data that might be used should always be ready. There’s no cold tier to retrieve from. No class transitions. No delays or rehydration logic.

“We don’t believe in hot versus cold,” said Patel.

“We believe in storing it once — always ready, always available — and priced so it’s still economical.”

In AI, that means:

  • Your training sets are instantly accessible
  • Your long-tail datasets are available for new pipelines
  • You avoid GPU starvation from delayed retrievals

How AI Rewrites the Storage Lifecycle

The podcast discussion outlined a new reality: storage lifecycle rules are no longer static. What was “rarely accessed” last quarter could be foundational next quarter. Here’s why:

  • AI models are retrained frequently as new data and use cases emerge
  • Multimodal models use older content (video, transcripts, text) as signal
  • RAG systems dynamically query large datasets for real-time inference
  • Compliance and audit demands require access to long-term history

“You don’t know when that data becomes valuable again,” Patel emphasized.

“If it’s stuck in cold storage, you’re at a disadvantage.”

It’s Not Just AI: Hot Storage Powers Media and SaaS Workflows Too

AI gets the headlines, but always-hot architecture matters for other use cases:

  • Media: Long-form content libraries, VFX assets, project archives
  • DevOps: System telemetry, CI/CD artifacts, audit trails

All of it may be “old” — but in modern workflows, age ≠ inactivity.

What to Look for in Always-Hot Storage

If you’re rethinking your cold/hot model, here’s what matters:

Capability Why it matters
Flat-rate, predictable pricing No tricks, no transition fees.
Low-latency access by default No “warm-up” period for your data.
S3-compatible interfaces Works with your existing pipelines.
Scalability to petabytes Ready for AI-scale datasets.
No tiering rules to manage One class. One behavior. No complexity.
