Why 4K Disk Sectors Improve Reliability, Capacity, and Performance

Switching from traditional 512‑byte sectors to 4096‑byte (4K) sectors enhances error‑correction, increases usable capacity, and can affect I/O performance; proper partition alignment is crucial, as misaligned partitions cause significant read/write slowdowns across various Linux file systems, as shown by benchmark tests.
