Today’s websites and applications require reliable storage for databases, backups, images, videos and business files. Block Storage vs Object Storage – Must know comparison for right storage solution. Each option is designed to meet different workloads and performance needs, scaling needs, and file storage.
The three most popular types are block storage, file storage and object storage. Each has their own approach to data and each is better for some workloads than others.
Knowing the differences will help you choose the right storage for hosting, databases, backups and business apps.
What Is Block Storage?
The data is broken down into fixed-size blocks and each block is stored separately in block storage. The blocks together make up a storage volume that the operating system or application can recognize.
Block storage is no different than any other hard disk. You can format it or install applications, databases or operating systems on it.
Block storage typically provides low latency and predictable performance. This is good if there is a lot of reading and writing to do in the applications .
Common uses of block storage
- Database servers
- Virtual machines
- Operating system drives
- High performance applications
- Transaction intensive workloads
For example, a hosting provider might use block storage for a MySQL VPS. The database can directly read and write data to the attached storage volume.
What Is Object Storage?
Data is saved in object storage as objects. Each object contains real data and metadata and unique identifier.
Applications do not organize information in folders and directories, they retrieve objects via APIs.
Object storage scales very well and is especially suited for large amounts of unstructured data.
Common uses of object storage
- Website images and videos
- Backups
- Archives
- Log files
- Static website assets
- Application-generated files
For example, a website can save thousands of product images in an object store. The application can pull each image on an as-needed basis, without using the local disk of its main server.
What Is File Storage?
File storage organizes data into files and folders. It functions much like the storage system on your computer.
All users and applications can access the shared directories via protocols like NFS or SMB. When configured for sharing, the same files can be accessed by multiple systems as well.
Common uses of file storage
- Shared business documents
- Media files
- Application files
- Development environments
- Shared hosting resources
File storage is best when your applications need a shared and familiar folder-based structure.
Block Storage vs Object Storage vs File Storage
| Feature | Block Storage | Object Storage | File Storage |
|---|---|---|---|
| Data structure | Blocks | Objects | Files and folders |
| Performance | High | Moderate to high | Moderate to high |
| Scalability | Good | Excellent | Good |
| Access method | Mounted volume | API/HTTP | File protocols |
| Best for | Databases and VMs | Backups and media | Shared files |
| Organization | File system managed by OS | Object IDs and metadata | Directories and folders |
| Typical workload | Frequent read/write | Large unstructured data | Shared file access |
How Do They Work in Hosting?
What your hosting environment needs to do determines the right storage type.
Block storage is often good for a database or VPS server. Databases need predictable disk performance. Low-latency storage is important because frequent transactions can lead to a lot of read/write operations.
Object storage is a better choice for backups, images, videos and other large files. The files can be stored separately and accessed as needed rather than filling the primary disk on the server.
File storage can support applications that require shared folders. For example a team application could store documents in one shared location accessible by several servers.
Simple Storage Architecture
A basic hosting environment might use all three storage types together:
Hosting Infrastructure
|
+--------------+--------------+
| | |
Block Storage Object Storage File Storage
| | |
Database Backups Shared Files
VPS Disk Images Documents
OS Files Videos App Data
This approach allows each storage system to handle the workload it is designed for.
Which Storage Should You Choose?
If you are more concerned about the application performance and read/write operations, then go for block storage. It is especially suited for databases, VPS instances and transactional applications.
Use object storage when you want to store large amounts of unstructured data. Common examples are backups, media libraries, archives and static assets.
Choose file storage if your apps or users need a familiar folder structure and to share files.
The decision does not need to be either/or. A lot of the applications we have today use a mix of different storage types. For example, a web app could have a database on block storage, uploaded images on object storage and shared documents on file storage.
Conclusion
It’s not really a choice between block storage and object storage. Each storage model is designed to solve a different problem.
Block storage is for performance, direct disk access. Object storage is designed for scale and large unstructured data. File storage is all about sharing files and directories.
Consider the data type, performance needs, scalability needs, access method and budget when choosing storage. Match the storage architecture to the workload and your hosting environment becomes easier to manage and more efficient as your application grows.
