The article explains block, file, and object storage by describing their core characteristics, advantages, disadvantages, typical scenarios, and provides a concise comparison to help readers quickly choose the appropriate storage type for databases, shared files, or massive media assets.
This article explains the core components and operation of SSDs—including controllers, NAND flash, block and page structures, program/erase cycles, garbage collection, wear‑leveling strategies, bad‑block handling, data‑redundancy mechanisms, namespace concepts, over‑provisioning, and key reliability metrics—providing a comprehensive technical overview for storage engineers.
This article explains the structure of Linux Ext2/3/4 filesystems, the role of superblocks and block groups, compares hardware and software RAID implementations with mdadm, and introduces LVM for flexible storage management, highlighting their benefits and limitations.
As global data volumes surge toward 163 zettabytes by 2025, traditional file and block storage struggle to scale, making object storage—offering unique IDs, metadata binding, and effortless scalability—the preferred solution for handling massive, mostly unstructured data in modern cloud environments.
A colleague was amazed when the cp command copied a 100 GB file in less than a second, prompting an investigation that reveals the difference between logical file size and physical block usage, the role of inodes, direct and indirect block indexing, and how sparse files make such copies appear instantaneous.
A colleague copied a 100 GB file with the cp command and it finished in under a second, prompting an investigation that reveals the difference between a file's logical size and its physical block usage, the role of inodes, direct and indirect block indexing, and how sparse files make such rapid copies possible.
This article explains why copying a seemingly 100 GB file with the cp command finishes almost instantly by exploring sparse files, the difference between file size and physical block usage, inode structures, multi‑level block indexing, and how modern file systems efficiently manage storage.
This article explains the fundamentals of data storage, covering hard‑disk hardware, internal structures, logical volumes, file systems, and the differences between direct‑attached, network‑attached, and storage‑area network solutions.
An in‑depth look at the evolution of hard‑disk technology—from IBM’s 1973 Winchester drive to modern 4 KB sector formats—covering disk structure, CHS geometry, fdisk analysis, and the importance of 4K alignment for performance and compatibility.
