A home NAS replaces USB drives and external hard drives with centralized, always-on storage that handles backup, Plex streaming, virtual machine storage, and file sharing. Unlike cloud services, your data stays on your network — no subscription fees, no bandwidth throttling, no corporate data collection.
The Synology and QNAP ecosystems dominate consumer and prosumer NAS markets. Both offer user-friendly interfaces, extensive third-party app ecosystems (Docker, Plex, Nextcloud), and reliable hardware. The choice comes down to processor performance, networking speed (1G vs 2.5G), storage capacity (2-bay vs 4-bay), and budget.
This page compares four proven models across the home lab and power user spectrum: two 4-bay units with different performance tiers, one budget 4-bay entry point, and one compact 2-bay option for users with modest storage needs.

Which One Is Right for You?
Answer three questions to find your fit:
1. How many bays do you need?
- 1–2 drives: a 2-bay NAS (TS-253E) is sufficient for single-drive backup or mirrored RAID 1.
- 3–4 drives: 4-bay NAS (DS423+, TS-464, DS923+) gives you RAID protection and room to expand.
- 5+ drives: consider a 4-bay NAS with expansion capabilities (DS923+, TS-464 with PCIe expansion).
2. Do you need 2.5G networking?
- No (using 1G internet, small files, occasional access): 1G LAN is sufficient. The DS423+ saves cost here.
- Yes (gigabit internet, multiple simultaneous clients, large file transfers): choose a 2.5G model (TS-464, TS-253E, DS923+ with upgrade module).
3. Will you run Plex with transcoding?
- No (storage-only, Nextcloud, or local backups): any model works; prioritize bays and budget.
- Yes (streaming 4K, variable bitrate to multiple clients): the AMD Ryzen (DS923+) or better Intel quad-core (TS-464) helps. The J4125 (DS423+) struggles with concurrent transcoding.
Synology DS923+ Top Pick
The DS923+ pairs a capable AMD processor with DSM (DiskStation Manager), Synology’s polished web interface. The Ryzen R1600 outperforms Intel Celeron processors in single-threaded tasks — meaningful for Plex transcoding when you have one or two simultaneous streams.
The 4GB RAM baseline is enough for most use cases (file serving, Plex, Docker containers). The NVMe cache slot accepts a SATA SSD for read caching on large sequential workloads, useful for media servers or VM storage.
The base LAN setup uses two 1G ports. A 2.5G expansion module (sold separately) adds faster bulk transfers and Plex streams to power users. The 4-bay design scales to 9 drives with the optional DX517 expansion chassis.
Best suited for: home labs with Plex, backup systems serving multiple devices, users who may want to expand storage in the future, light virtualization tasks.
Available at B&H Photo and Amazon.
QNAP TS-464 Power User
The TS-464 ships with 8GB RAM and dual 2.5G LAN ports — advantages over the DS923+ for users wanting faster networking without extras. The Intel N5105 is a quad-core Celeron with modest but consistent performance; it trades single-threaded Plex transcoding speed for lower power and better efficiency.
The two NVMe slots allow a mirrored SSD cache or separate read/write caches, a flexibility the DS923+ doesn’t match. The QNAP app ecosystem (via App Center) mirrors Synology’s, with Plex, Nextcloud, and Docker available.
The 2.5G LAN ports are the standout feature — no adapter needed. The TS-464 is the best value for users prioritizing network speed and who don’t need the CPU horsepower of the Ryzen DS923+.
Best suited for: users with gigabit or faster internet, small business backup, multi-user file sharing, light transcoding or transcoding-optional setups, users building with budget constraints.
Available at B&H Photo and Amazon.
Synology DS423+ Best Value
The DS423+ is Synology’s entry-level managed NAS. It keeps the same DSM interface and app ecosystem as pricier models but trades features for cost: one 1G LAN port, no NVMe cache, limited RAM, and a modest Celeron J4125 processor.
The single 1G port is the biggest limitation — you can’t load-balance across multiple gigabit links, and throughput caps at ~125 MB/s on large file transfers. The 2GB RAM baseline requires an upgrade to 8GB for comfortable Docker and multi-user operation.
The CPU is sufficient for basic file serving, backup, and non-transcoding Plex libraries. It struggles with transcoding multiple streams.
At $299 list price, the DS423+ suits users with modest storage needs (2–4 small drives), homes with single-gigabit internet, and those prioritizing low power consumption (40W idle is very efficient).
Best suited for: small homes, personal backup-only use cases, users new to NAS, power-conscious deployments, single-user households.
Available at B&H Photo and Amazon.
QNAP TS-253E Best 2-Bay
The TS-253E is a compact 2-bay NAS with the connectivity of a 4-bay: dual 2.5G LAN ports, a PCIe expansion slot for cache or additional storage, and 8GB baseline RAM.
The two-bay design is ideal for:
- Mirrored RAID 1 backup (two large drives) in a small space
- Compact home labs or dorms
- Secondary NAS for media or VM storage
- Plex servers with limited storage needs (4TB–8TB total)
The J6412 quad-core processor is faster than the DS423+ and TS-464’s N5105, with better burst performance. The dual 2.5G ports match the TS-464’s networking advantage.
The trade-off: only two drive bays. You can’t grow to 4, 6, or 8 drives. If you anticipate storage growth, choose a 4-bay model.
Best suited for: space-constrained homes, users needing simple RAID 1 backup, secondary Plex servers, small labs, apartments.
Available at B&H Photo and Amazon.
Synology vs QNAP: The Practical Differences
Processor & Transcoding: The DS923+ (AMD Ryzen) outperforms all other three in single-stream Plex transcoding. If you plan to support 2–3 concurrent 1080p→720p transcodes, the DS923+ is the clear choice. The TS-464, TS-253E, and DS423+ are better suited to “direct play” Plex libraries (pre-transcoded or low-bitrate content).
Networking: The TS-464 and TS-253E ship with dual 2.5G LAN. The DS923+ requires a separate 2.5G ethernet module (~$40–60) to match that speed. The DS423+ maxes at 1G. If gigabit-fast file transfers matter to you, the QNAP units save you money and configuration.
Power Efficiency: The DS423+ draws the least power (~40W idle) and is ideal for always-on small deployments. The others range from 50–65W, which over a year of 24/7 operation adds ~$40–70 to electricity costs.
Expandability: The DS923+ supports up to 9 drives via the optional DX517 expansion chassis. The TS-464 can expand via PCIe external enclosures (less elegant). The DS423+ and TS-253E are hard-capped at 4 and 2 bays, respectively.
RAM Upgradability: All four support RAM upgrades. The DS923+ and TS-464 max out at 32GB; the DS423+ at 8GB; the TS-253E at 16GB.
Storage Sizing
For a home NAS, a common starting point is:
- Backup-only: 2 drives (RAID 1 mirror) in a 2-bay NAS
- Backup + Plex: 4 drives (RAID 10 or SHR2) in a 4-bay NAS, 4–8 TB per drive
- Multi-user home lab: 4 large drives (16–20 TB each) in a 4-bay NAS, with 10G or 2.5G networking
NAS drives (WD Red Plus, Seagate IronWolf) cost $15–20 per TB for new stock as of March 2026. Budget $60–160 for drives, on top of the NAS enclosure cost.
Verdict
- If you transcode Plex: DS923+ (AMD Ryzen advantage).
- If you need 2.5G today: TS-464 (dual 2.5G LAN included, good price, no modules).
- If you’re on a tight budget: DS423+ ($299, sufficient for backup and light use).
- If you need compact 2-bay: TS-253E (fast, networkable, expandable via PCIe).
All four are reliable, well-reviewed, and actively maintained by their vendors. The choice hinges on your storage growth plans, network speed needs, and whether Plex transcoding is essential.
