Question

1. File Storage (the classic one) What it isData is stored as files inside folders (directories). Exactly how your laptop works. How you access itPath-based access/documents/reports/2025.pdf Key traits Hierarchical (folders → subfolders → files)Easy to understandShared access (multiple users can mount it) Best for File sharing systemsHome directoriesCMS content (images, PDFs)Legacy applications Examples Windows File ServerNFSSMBAmazon EFS Limitation Doesn’t scale infinitelySlower with massive numbers of files 2. Block Storage (the performance beast) What it isDr fileata is split into fixed-size blocks, each with an address—but no metadata o structure. The OS builds a file system on top of it. How you access itAttached directly to a server (like a virtual hard disk) Key traits Very fastLow latencyFine-grained read/write Best for DatabasesVirtual machine disksTransaction-heavy appsERP systems Examples Amazon EBSAzure Managed DisksSAN Limitation Usually attached to one server at a timeScaling requires manual management 3. Object Storage (the cloud-native giant) What it isData is stored as objects, each containing: The data itselfMetadataA unique ID No folders—just a flat namespace. How you access itHTTP/HTTPS via APIsGET /bucket/object-id Key traits Massive scalabilityMetadata-richCost-effectiveBuilt for the internet Best for Images, videos, backupsLogsBig dataStatic website hosting Examples Amazon S3Azure Blob StorageGoogle Cloud Storage Limitation Higher latency than block storageNot ideal for frequent small updates Quick comparison Feature File Storage Block Storage Object Storage Structure Folder-based Raw blocks Flat objects Access File path Disk-level REST API Performance Medium Very high Medium–low Scalability Limited Moderate Massive Best for Shared files Databases Media & backups One-line analogy File storage → A filing cabinet Block storage → A high-speed hard drive Object storage → A global warehouse with barcodes
