# Storage Tiers

> Choose between Standard (HDD) and Edge (SSD) storage tiers based on your performance requirements

Bunny Storage offers two storage tiers optimized for different use cases and performance requirements.

## Standard (HDD) tier

The Standard storage tier is optimized for low cost, high throughput global file storage and delivery.

**Specifications:**

* **Storage type**: HDD-based
* **Latency**: Variable (30-300ms)
* **Replication points**: Up to 9 regions (HTTP API/FTP) or 8 regions (S3-compatible)
* **Primary region**: Any available region
* **Recommended regions**: Geographically diverse

**Best for:**

* Object storage
* Video delivery
* File hosting
* Large file storage
* Cost-sensitive applications
* Moderate performance requirements

## Edge (SSD) tier

The Edge storage tier is optimized for ultra-high global performance powered by strictly SSD storage.

**Specifications:**

* **Storage type**: SSD-based
* **Latency**: Consistent (1-5ms)
* **Replication points**: Up to 15 regions (HTTP API/FTP) or 8 regions (S3-compatible)
* **Primary region**: Frankfurt (DE) only
* **Recommended regions**: As many as possible

**Best for:**

* Perma-Cache
* Website acceleration
* High performance content delivery
* Small files
* Applications where performance is paramount
* Low latency requirements

> [!NOTE]
>
> Edge (SSD) tier requires Frankfurt (DE) as the primary region. All uploads go
> through Frankfurt first, then replicate to your selected regions.

## S3 compatibility impact

When S3 compatibility is enabled, the number of available replication points is reduced:

| Tier | HTTP API/FTP | S3-compatible |
| - | - | - |
| Standard | Up to 9 regions | 8 regions |
| Edge (SSD) | Up to 15 regions | 8 regions |

## Choosing a tier

Consider these factors when selecting your storage tier:

**Choose Standard if:**

* Cost is a primary concern
* Files are large (videos, archives, backups)
* Latency of 30-300ms is acceptable
* Files are primarily accessed via CDN (cached)

**Choose Edge (SSD) if:**

* Performance is critical
* You need consistent low latency (1-5ms)
* Files are small and frequently accessed
* You're using Perma-Cache or website acceleration
* Budget allows for premium performance

> [!NOTE]
>
> The storage tier cannot be changed after zone creation. Choose carefully based
> on your long-term requirements.
