Object Storage vs Block Storage
The cloud offers different kinds of storage for different jobs. Two of the most common are object storage and block storage. Choosing the right one affects both performance and cost.
This article explains the difference without the jargon.
Object Storage
Object storage keeps files as self-contained objects in a vast, flat pool — think of an enormous, infinitely large filing cabinet. It is ideal for images, documents, backups and media, and it is inexpensive and effectively limitless.
Block Storage
Block storage behaves like a traditional hard drive attached to a server. It is fast and well suited to databases and operating systems that need to read and write quickly, but it is tied to a single server at a time.
| Use case | Best choice | Why |
|---|---|---|
| Website images and downloads | Object storage | Cheap, scalable, easy to serve |
| Database files | Block storage | Fast, low-latency read/write |
| Backups and archives | Object storage | Low cost for large volumes |
