![]() ![]() We have to know that blocks #1, #3, #4, and #6, highlighted in yellow, are part of the same sentence. I might save those parts like so:īlocks for a single file don’t have to appear next to each other or even in the correct order. Suppose I have a block storage volume with 4-character blocks, and I want to save the sentence “I am called Alex.” That won’t fit in a single block, so I have to split it into multiple parts. A single block doesn’t know it’s part of a file or which other blocks it should be combined with. You have to remember which blocks you’re using because the storage volume won’t. You read and combine the same blocks to retrieve the file later. If you want to store a large file, you have to split it up and write it to multiple blocks. Block storage is any storage that keeps data in block storage volumes. A block storage volume is a collection of blocks, each with a unique identifier, and each block can be read and written individually. How does block storage work?Ī block is a tiny chunk of data. ![]() We’ll look at how each of these storage technologies work, what they’re good for, and how to use them. They all work differently, and they all have unique characteristics that make them suitable for different types of workload. This is the first article in a three-part series about the common types of storage in the cloud: block, file, and object. It’s ideal for local storage and high-performance workloads. It divides data into small units called “blocks,” which provide fast and flexible ways to manage data. Block storage is a low-level technology that underpins the majority of modern storage - including whatever device you’re reading this on. ![]()
