One-page printable guide: DAS vs NAS vs SAN at a glance (access level, live-recording target, scaling), the five RAID levels compared (min disks, usable capacity, failures survived, write penalty, surveillance fit), the two-budget sizing recipe (capacity and sustained write throughput), the surveillance-drive and CMR-not-SMR checklist, the rebuild-danger-window warnings, and a blank per-array sizing worksheet.

Fora Soft Video Engineering Handbook
This on-prem storage architecture guide compares DAS, NAS and SAN, five RAID levels and the capacity and write-throughput sizing recipe for surveillance recording. Our seven-volume handbook covers the video stack; start with Volume 1 on H.264, HEVC and bitrate, which set how much you store, then Volume 6 on computer vision and Volume 7 on compliance. Written by Nikolay Sapunov, CEO at Fora Soft.
