NAS storage and setup guides

Plan capacity, RAID, drives, backup, networking, Plex storage and expansion.

1GbE vs 2.5GbE for Plex

For most Plex households, 1GbE is enough for direct-play streaming, while 2.5GbE mainly adds headroom for concurrent users, large file transfers, and NAS expansion. The bigger Plex limits are often client compatibility, internet upload speed, storage, and transcoding hardware.

How Much Storage Do You Need for a Plex Library?

Estimate Plex storage from your actual media bitrate, runtime, library size, and expected growth—not from title counts alone. This guide also explains how direct play, transcoding, remote streaming, RAID, backups, and NAS expansion affect your purchase.

Direct Play vs Transcoding in Plex

Plex can often stream media directly from a NAS without demanding much CPU power, but incompatible clients, subtitles, remote connections, and multiple users can trigger transcoding. This guide explains how to match NAS compute, storage, networking, and backup plans to your Plex workload.

NAS for Multiple Plex Streams

Size a Plex NAS around simultaneous direct-play and transcoded streams, media bitrate, remote upload capacity, storage growth, and backup needs. This guide explains what CPU, memory, networking, RAID, and hardware transcoding can—and cannot—solve.

NAS Drive Buying Checklist

Use this final NAS drive checklist to match capacity, media type, interface, endurance, noise, power use and warranty to your workload. It also covers RAID and compatibility decisions before you buy.

How to Tell If a Hard Drive Is CMR or SMR

Verify whether a specific hard drive uses CMR or SMR before putting it in a NAS. This guide explains where to find reliable evidence and how recording technology affects workloads, RAID, ZFS, and drive selection.

NAS HDD vs Desktop HDD

NAS hard drives are designed for multi-drive, always-on workloads, while desktop hard drives target lighter single-computer use. This guide explains when a desktop drive is reasonable, when it creates RAID or reliability risks, and how to compare the total cost per usable TB.

Should You Use SSDs in a NAS?

SSDs can make a NAS quieter and more responsive, but they are not automatically faster for every workload. This guide explains when SATA SSDs, NVMe SSDs, or HDDs offer the best value for capacity, endurance, networking, and RAID.

RAID Planning Checklist Before You Buy Drives

Choose a RAID level, drive count, and spare strategy from your capacity target—not from raw drive count alone. This checklist covers failure tolerance, rebuild risk, expansion, and why RAID is not a backup.

How Many Drives Can Fail in RAID 5?

RAID 5 can tolerate exactly one failed drive in an array. Learn how that limit affects usable capacity, rebuild risk, expansion, and your backup plan.

SHR vs Traditional RAID

Synology Hybrid RAID (SHR) can make mixed-size drive upgrades more flexible than traditional RAID, but the trade-off depends on the number, size, and layout of your drives. This guide compares capacity, failure tolerance, rebuilds, expansion, and backup requirements.

RAID 5 vs RAID 10

RAID 5 uses parity to deliver better usable capacity, while RAID 10 uses mirroring for simpler rebuilds and strong write performance. Compare failure tolerance, capacity, expansion, and backup requirements before choosing a NAS array.

RAID 10 Explained for NAS

RAID 10 combines mirrored drives with striping to deliver strong random I/O performance and predictable redundancy. Learn how much capacity it uses, how failures and rebuilds work, and when it is a better choice than RAID 5 or RAID 6.

NAS Capacity Planning Checklist

Calculate the usable NAS capacity you actually need after RAID, filesystem overhead, snapshots, and free-space headroom. This checklist also covers growth, backups, drives, networking, Plex, and surveillance.

Why a 40TB NAS Does Not Give You 40TB Usable

A NAS advertised with 40TB of drives will usually provide much less than 40TB for files. RAID or parity, decimal-versus-binary units, filesystem overhead, snapshots, and free-space headroom all reduce the practical capacity.

How Much Free Space Should You Leave on a NAS?

Keep at least 20% of a NAS pool free for stable performance and routine maintenance. ZFS, snapshots, heavy file changes, and future growth may justify reserving 25–30% or more.

How Much NAS Storage for 4K Video?

Calculate the NAS capacity needed for 4K footage from bitrate, recording hours, RAID layout, backups, and free-space headroom. This guide includes formulas and a worked example.

How Much NAS Storage for Video Editing?

Estimate NAS storage for video editing by separating active projects, archives, RAID overhead, filesystem space and free-space headroom. A worked example shows how to translate footage and growth into a practical NAS size.

How Much NAS Storage for Photos?

Estimate NAS photo storage from your current library, average file size, shooting volume, RAID layout, backups, and future growth. This guide includes a worked capacity example and a practical sizing checklist.

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.

4-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.

2-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.

How 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.

NAS 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.
