File Storage
Open source distributed storage providing object, block and file from one cluster

The short version
- Each has a real cost: Box pricing not disclosed for Personal Pro, Business Plus, Enterprise, and Enterprise Plus tiers; Ceph ceph assumes an operator who understands placement groups, CRUSH rules and recovery tuning, so organisations without dedicated storage staff routinely end up with a cluster that works until the first failure and then does not.

Box

- Enterprise Advanced requires quote and minimum purchase commitments
- File upload limits vary from 250 MB to 500 GB across tiers
- Business plan requires minimum 3 users
Ceph
- Ceph assumes an operator who understands placement groups, CRUSH rules and recovery tuning, so organisations without dedicated storage staff routinely end up with a cluster that works until the first failure and then does not.
- Small clusters are inefficient: three way replication means a third of raw capacity is usable, and erasure coding needs enough failure domains to be safe, so the economics only work above a certain size.
- Recovery and rebalancing generate heavy internal traffic, so a failed disk can degrade client latency across the cluster unless backfill is throttled correctly beforehand.
- Upgrades must follow a strict daemon order across monitors, managers, OSDs and gateways, and a mistake in that order on a live cluster is difficult to reverse.
- Because it is self hosted, every byte served to the internet is transit you pay for on your own links, so the free licence does not mean free egress and bandwidth planning becomes your problem rather than the providers.

Answered from the vendors’ own pages
Box: What is the starting price for Box Business plan?
Business plan starts at $5 per user per month with unlimited storage, 5 GB file uploads, and Box AI included.
SourceCeph: How many nodes do I need to start?
Three is the practical minimum for a replicated cluster with real fault tolerance, and most production advice starts at five once you account for maintenance windows.
Box: Does the free plan support file sharing?
Yes, Individual free plan includes 10 GB storage, 250 MB file uploads, and 5 Box Sign signature requests per month.
SourceCeph: Is it faster than a SAN?
Not on single stream latency. It wins on aggregate throughput and on growing without a forklift upgrade, which is a different property from raw speed.
Box: What are the file upload limits by tier?
File upload limits are 250 MB (Individual), 5 GB (Business), 50 GB (Enterprise), 150 GB (Enterprise Plus), and 500 GB (Enterprise Advanced).
SourceCeph: Can I buy support?
Yes. IBM sells IBM Storage Ceph and SUSE and others have offered supported builds; the upstream project itself is free.
Box: How is AI priced in Box?
Business plan includes Box AI at no extra cost; Enterprise tiers include 1,000-20,000 AI Units per month depending on plan level.
SourceCeph: Should I use it just for S3?
If object is all you need, a dedicated object store is simpler to run. Ceph earns its complexity when you need block and file as well.
