-## Overview
+## Block Storage volume types overview
 
 <BlockStorageVolumeTypes />
 
-## Underlying hardware
-
-   - **Block Storage 5K IOPS volumes**:
-
-     - They are built using older-generation SSDs. This means that the hardware is slower, as it uses older SSD technology.
-     - The 5K IOPS is split between read and write operations, resulting in a total of 10K IOPS (5K for reads and 5K for writes).
-
-   - **Block Storage 5K IOPS volumes**:
-
-     - They are powered by modern NVMe (Non-Volatile Memory Express) disks.
-     - NVMe technology provides better performance and is optimized for high-speed storage operations.
-
-## Performance
-
-   - **Block Storage 5K IOPS volumes**:
-
-     - Their performance is limited by the older SSD hardware, which can result in slower data access and higher latency.
-     - The older technology may impact overall speed and responsiveness.
-
-   - **Block Storage 5K IOPS volumes**:
-
-     - Delivers better performance thanks to NVMe disks, which handle 5K IOPS for both read and write operations combined.
-     - This provides a significant boost in data processing speed and efficiency.
-
-## Latency
-
-   - **Block Storage 5K IOPS volumes**:
-
-     - Higher latency due to the use of older SSDs.
-     - This can lead to slower application response times, especially in scenarios requiring rapid data access.
-
-   - **Block Storage 5K IOPS volumes**:
-
-     - Offers lower latency and faster access times, making it ideal for applications that require quick data retrieval.
-     - The use of NVMe technology ensures a smoother and more responsive experience.

+| **Performance** | Limited by older SSD hardware, slower data access, higher latency. | Better performance with NVMe disks, 5K IOPS for both read and write combined, faster and more efficient. |
+| **Latency** | Higher latency due to older SSDs, slower application response times. | Lower latency, faster access times, ideal for quick data retrieval, smoother experience with NVMe. |
 
 ## Summary
 
-- **Block Storage 5K IOPS volumes** rely on older, slower SSD technology, leading to higher latency and lower overall performance.
-
+- **Block Storage legacy volumes** rely on older, slower SSD technology, leading to higher latency and lower overall performance.
 - **Block Storage 5K IOPS volumes** use advanced NVMe disks, offering improved performance, lower latency, and faster data access.
 
-For tasks where performance and are crucial, Block Storage volumes provide a more effective solution due to the modern hardware and technological improvements.
