Best NAS Devices for Home Office Backups
A NAS (Network Attached Storage) device is a small box with hard drives that connects to your home network and appears as shared storage to all devices on that network. For home offices, a NAS serves as local backup (the on-site copy in the 3-2-1 backup rule), a shared file server for teams or household members, and a media server for local streaming. Unlike cloud-only backup, a NAS backup is instantly accessible, has no monthly storage fees, and is not dependent on internet connectivity for recovery. The trade-off is upfront hardware cost and some setup complexity.
We selected these based on drive bay count, processor performance, RAM, network speed, software ecosystem (especially Synology DSM), RAID support, expandability, and practical fit for home office backup and shared storage.

Synology DS224+
Best for: The home office NAS standard — Intel Celeron processor, 2GB RAM, Synology DSM, and support for Synology’s full app ecosystem
The DS224+ uses an Intel Celeron J4125 quad-core processor with hardware transcoding — enabling direct-play and transcoding of video files served to multiple devices simultaneously. 2GB DDR4 RAM is included, expandable to 6GB. Two 3.5″ drive bays support standard SATA HDDs or 2.5″ SSDs. Synology DiskStation Manager (DSM) provides a polished browser-based OS with apps for file sync, backup, surveillance, and more. The DS224+ also connects to Synology’s cloud sync (Hybrid Share) and supports Active Backup for Business for server and PC backup.
Key specs: Intel Celeron J4125, 2GB DDR4 RAM (expandable to 6GB), 2× SATA bays (3.5″ or 2.5″), 2× USB 3.2, 2× Gigabit Ethernet (Link Aggregation), Synology DSM, RAID 0/1/JBOD
Caveat: Hard drives are not included — NAS drives (WD Red, Seagate IronWolf) must be purchased separately. Link Aggregation requires a managed switch that supports it. No 2.5GbE ports on the DS224+ — dual Gigabit with Link Aggregation is the wired option.
Price: Mid-range (chassis only; add drive cost).
Synology DS223
Best for: Simple home backup at a lower price — ARM-based 2-bay NAS for file storage and Time Machine backup without heavy processing demands
The DS223 uses a Realtek RTD1619B ARM quad-core processor — lower performance than the DS224+’s Intel Celeron but sufficient for basic file storage, backup, and cloud sync. No hardware transcoding. 2GB RAM. Two drive bays for SATA HDDs or SSDs. Synology DSM provides the same polished management interface as the DS224+. The lower processor means fewer simultaneous users and no real-time transcoding — right for individual or small household backup use cases.
Key specs: Realtek RTD1619B ARM, 2GB RAM, 2× SATA bays (3.5″ or 2.5″), 2× USB 3.2, 1× Gigabit Ethernet, Synology DSM, RAID 0/1/JBOD
Caveat: No hardware transcoding — video playback requires a capable client (Plex with transcoding disabled, or direct-play clients only). Lower peak throughput than the DS224+. For any media server use beyond direct-play, the DS224+ is the better investment.
Price: Mid-range, lower than DS224+ (chassis only).
Synology DS923+
Best for: 4-bay NAS for larger storage capacity — expandable to 8 bays, AMD Ryzen processor, and 10GbE upgrade option
The DS923+ uses an AMD Ryzen R1600 dual-core processor and 4GB ECC RAM for error-correcting memory. Four SATA bays hold up to 4 drives, with expansion to 8 drives via a Synology DX517 expansion unit (purchased separately). An optional 10GbE network adapter card upgrades the NAS network port to 10GbE for high-speed local transfers. RAID 5 and RAID 6 (fault-tolerant configurations with 3+ drives) are supported. Two M.2 NVMe slots for SSD cache acceleration of spinning disk arrays.
Key specs: AMD Ryzen R1600, 4GB ECC RAM (expandable to 32GB), 4× SATA bays, 2× M.2 NVMe cache slots, 2× Gigabit Ethernet (10GbE PCIe optional), expandable to 8 bays (DX517), RAID 0/1/5/6/10/JBOD
Caveat: Higher price tier — 4 drives plus chassis cost. The DS923+ requires NAS-grade drives (purchased separately). The Ryzen R1600 is a dual-core processor — sufficient for NAS workloads but not the fastest for parallel processing-heavy tasks.
Price: Premium range (chassis only; add 4 drive cost).
QNAP TS-233
Best for: Budget 2-bay NAS with QNAP’s QTS interface — for users who prefer QNAP or want a lower-cost Synology alternative
The TS-233 uses a Cortex-A55 ARM dual-core processor with 2GB RAM. Two SATA bays support standard HDDs or SSDs. QNAP’s QTS operating system provides a desktop-style interface with apps for file sharing, backup, multimedia, and cloud sync. A single Gigabit Ethernet port provides network connectivity. USB 3.2 and USB 2.0 ports support external drive connection. HDMI output allows connecting to a display directly for local media playback.
Key specs: Cortex-A55 dual-core, 2GB LPDDR4 RAM, 2× SATA bays, 1× Gigabit Ethernet, 2× USB 3.2, 1× USB 2.0, HDMI, QTS OS, RAID 0/1/JBOD
Caveat: QNAP QTS has a steeper learning curve than Synology DSM for new NAS users. The TS-233 is an entry-level device — not suitable for multi-user environments or intensive workloads. Synology DSM’s software ecosystem and documentation are generally considered more polished.
Price: Budget to mid-range (chassis only).
WD My Cloud Home
Best for: Consumer NAS without drive selection or RAID management — pre-configured personal cloud storage
The WD My Cloud Home is a consumer-oriented NAS that ships with drives pre-installed in 2TB to 8TB capacities. Setup requires only a network connection and a WD account — no drive selection, no RAID configuration, and no complex setup. Files are accessible via the My Cloud app on desktop and mobile. Automatic photo backup from connected mobile devices is built in. Unlike Synology or QNAP NAS devices, the My Cloud Home is not user-serviceable — drives cannot be replaced by the user.
Key specs: Pre-installed HDD (2–8TB options), 1× Gigabit Ethernet, USB 3.0, My Cloud app (desktop + mobile), automatic photo backup, WD Plex Media Server
Caveat: Consumer-grade — not suitable for business-critical data or multi-user access. Drives are not user-replaceable. No RAID — a single drive failure means data loss unless backed up to another location. The My Cloud Home is a convenience product, not a professional backup solution.
Price: Mid-range (includes drives; varies by capacity).
How to choose
- Drive bays: 2-bay NAS supports RAID 1 (mirroring — one drive can fail without data loss) or JBOD (combined capacity, no redundancy). 4-bay NAS supports RAID 5 and RAID 6, which tolerate one or two drive failures. More bays also mean more raw storage capacity.
- Synology vs. QNAP: Synology DSM is widely regarded as the more polished and beginner-friendly NAS operating system. QNAP QTS is feature-rich but with a steeper learning curve. For first-time NAS buyers, Synology DSM reduces friction. For experienced users who want hardware flexibility, QNAP offers more hardware options at comparable prices.
- NAS drives vs. desktop drives: NAS enclosures generate vibration and run 24/7 — NAS-rated drives (WD Red, Seagate IronWolf) are designed for this. Standard desktop drives in a NAS have higher failure rates. Always use NAS-rated drives.
- 3-2-1 backup rule: A NAS is the local copy in the 3-2-1 rule (3 copies, 2 media types, 1 off-site). A NAS alone is not a complete backup — pair it with cloud backup (Synology supports Backblaze B2, Amazon S3, and others) for the off-site copy.
- Who should skip this category: If you have fewer than 2TB of data and are comfortable with cloud-only storage, a NAS adds cost and complexity without proportional benefit. NAS devices deliver clear value when local access speed, data volume, or ongoing cloud storage costs make cloud-only impractical.
