Difference Between Object Storage vs Block Storage
Object storage usually refers to the storage spaces that we use and organize in the form of objects. It is generally referred to as the data that we stored as bits or bytes in a file. In object storage, data is stored as metadata and as a unique identifier.
Block storage is the oldest version of data storage that stores data in blocks or chunks. In block storage, the address forms the identification part that forms the blocks, and that is why no metadata is included in block storage.

Key Differences of Object Storage vs Block Storage
Let us study some key differences between Object Storage vs Block Storage:
Although the term object and blocks produce a similar sound to work still, there are differences between object storage and block storage that I will discuss right now.
The biggest difference is in the way of handling data storage.
- In cloud computing, object storage stands for storing and retrieving useful data as metadata or in the form of objects using an Application Programming Interface (API). Various clients are associated with it, and various operating systems and programming languages are connected with it. Block storage is the old, traditional way of storing large chunks of data in the form of blocks like a hard disk drive. It supports many files and file systems distributed over people worldwide.
- Object storage offers affordability since the cool way to use the storage is purchasing the desired software for use and playing it accordingly. Whereas, in traditional block storage, a user has to pay for all storage spaces, whether allocated or unallocated, whether it is used or not.
- Object storage provides storing of the huge size of metadata and data blob that can produce a more efficient result in terms of performance and strengthen the overall infrastructure. However, in the case of block storage, they have limited spaces for storing metadata and data blobs; any additional information can create complexity in maintaining the infrastructure.
- Object storage services provide high latency, which is why they are not suitable for any operational changes in the database. Whereas block storage services provide low latency that helps in any operational performance in a database.
- Object storage provides us with a feature of optional versioning that helps in retrieving older versions of objects to get back the data that may be overwritten or mistyped. Block storage does not provide such a feature.
- Object storage services offer popular service providers in the cloud that does not require any hard drives or arrays to maintain. But, block storage has to maintain chunks of data in blocks that are saved in local storage or hard disks.
- Object storage has built-in support in the cloud in the form of backups, security, maintenance, offers scalability to use high-level test cases having a hassle-free communication and less rework needed for maintain resources by the developers and block storage services require a lot of setup and hands-on-work to build a complete architecture.
Object Storage vs Block Storage comparison Table
Below is the primary comparison:
| Basis of Comparison | Object Storage | Block Storage |
| Units of storage | The object storage is stored as customizable, large storage of data mainly in the form of objects. It stores files and files systems stored as metadata used today in cloud computing platforms. | The block storage is stored as huge chunks of data in the form of blocks that are used in the older version of storing files. It does not have the concept of metadata storage. |
| Updates of services | The object storage services do not have in-place update support that can produce new and newer versions of objects that will bring complexity to the overall architecture and hamper overall performance efficiency | lock storage supports in-place updates that can create new and newer versions of blocks for storage purposes. |
| Performance Management | The object storage performs the best with high efficiency for big file systems and large organizations where data is required regularly, and resources are gathered. | The block storage has optimized performance level on storing data in the database server and where transactions are happening to store blocks of data. |
| Flexibility in storage | In object storage, data can be accessed and retrieved from any geographic region, not region-bounded. Therefore, users can access storage anywhere and at any place whenever they want. | In block storage, storing data and accessing a region far away from it can increase latency and storage issues in a database that can lead to a substantial change in overall performance. |
| Scalability in storing dataObject | The object storage provides the best scalability feature as it can store and scale a huge volume of data from petabytes to infinity without any hassle. | Since the address is served as the information part of the blocks in block storage, scalability is an issue and has a greater limitation as compared to object storage. |
| The best use case for | Object storage is best used for static file data that serve as cloud storage. | The block storage blocks are stored as transactional data and as changing data that gets changed frequently. |
| Workload | Object storage can store feature-rich metadata, large-scale analytics to store and retrieve. | Block storage has limited access to data but in terms of output and performance produces a consistent result. |
| The biggest strength of use | Object storage services are cheaper, consistent, but the latest object version does not have immediate data; alteration provides transferring a new object version. | Block storage is expensive and reliable and data can be produced immediately. |
| Limitations | It does not provide a sharing protocol and inefficient for transactional data. | Storage provides difficulty while expanding the region. |
Conclusion
It is always difficult for programmers to choose correct storage but in today’s world, object storage provides a fast and newer way of storing data in a cloud server than the old traditional way of data storage as blocks.
