How Much NAS Storage for a Small Business?
Most small businesses should size a NAS from projected usable capacity—not the raw total printed on the drives. Add RAID or parity overhead, filesystem overhead, free-space headroom, versioned backups, and several years of growth before choosing the NAS.
Read guide4-Bay vs 8-Bay NAS
A 4-bay NAS is usually more efficient for a modest storage pool, while an 8-bay NAS provides more usable capacity, better expansion headroom and more flexible RAID layouts. This guide compares capacity, redundancy, power use, backups and upgrade paths.
Read guide2-Bay vs 4-Bay NAS
A 2-bay NAS can be enough for a mirrored home file server, but a 4-bay model provides more usable capacity, RAID options and room to grow. Compare capacity, redundancy, backups and expansion before choosing.
Read guideHow Many Drive Bays Do You Need in a NAS?
Choose NAS drive bays by starting with usable capacity—not raw disk capacity—and then allowing for RAID, filesystem overhead, free space, backups, and future growth. This guide compares 2-bay, 4-bay, 6-bay, and larger NAS systems.
Read guideNAS Storage Calculator: How to Estimate Usable Capacity
Estimate NAS capacity from drive count and size by separating raw storage, RAID or parity, filesystem overhead, and free-space headroom. A worked example shows how much space you can realistically plan to use.
Read guideHow Much NAS Storage Do I Need?
Calculate the NAS capacity you actually need by accounting for your files, growth, RAID or parity, filesystem overhead, snapshots, and free-space headroom. A worked example shows why raw drive capacity is not the same as usable storage.
Read guideBacking Up Laptops to a NAS
Learn how to automate laptop backups to a NAS, size storage for multiple computers, choose retention rules, and test restores. This guide separates RAID, snapshots, and true backups so you can build a practical 3-2-1 protection plan.
