Prices change; check the retailer before buying. Disclosure: https://homelabpicks.com/disclosure/ ## Verdict **[TerraMaster F4-424 Pro](https://homelabpicks.com/go/terramaster-f4-424-pro)**: 32 GB of DDR5 and an 8-core Intel Core i3-N305 out of the box, so a large container stack fits without a memory upgrade. ## Products ### Our Pick: [TerraMaster F4-424 Pro](https://homelabpicks.com/go/terramaster-f4-424-pro) It ships with the most memory in this roundup. The 8-core i3-N305 and 32 GB of DDR5 leave room for memory-hungry apps such as Immich and a database without an upgrade. - CPU: Intel Core i3-N305 (8C/8T, up to 3.8 GHz) - RAM: 32 GB DDR5 SODIMM (one slot, 32 GB max) - Bays: 4x SATA + 2x M.2 NVMe (PCIe 3.0 x1) - Network: 2x 2.5GbE - Expansion: No PCIe slot Pros: - 32 GB DDR5 installed, the most in this roundup - 8-core i3-N305 for many concurrent services - Intel Quick Sync for Jellyfin or Plex containers - HDMI 2.0b output Cons: - TOS Docker Manager is not our preferred container-management interface - 32 GB is also the official maximum - No PCIe slot for 10GbE - TerraMaster voids the warranty if you install another OS ### Best Value: [QNAP TS-464](https://homelabpicks.com/go/qnap-ts-464) The best balance of container software, CPU, and expansion. Container Station runs Docker, LXD, and Kata containers, and the PCIe slot can add 10GbE later. - CPU: Intel Celeron N5095 (4C/4T, up to 2.9 GHz) - RAM: 8 GB DDR4 (two SODIMM slots, 16 GB max) - Bays: 4x SATA + 2x M.2 NVMe (PCIe 3.0 x1) - Network: 2x 2.5GbE - Expansion: PCIe Gen 3 x2 slot Pros: - Container Station supports Docker, LXD, and Kata containers - PCIe Gen 3 x2 slot for a 10GbE card - Intel Quick Sync for media containers - HDMI 2.1 output Cons: - 16 GB official memory ceiling - Four cores and four threads - QTS needs prompt patching and should not be exposed directly to the internet ### Best Software: [Synology DS925+](https://homelabpicks.com/go/synology-ds925) Our preferred interface for managing containers. Container Manager runs Compose projects from the DSM interface, and ECC memory up to 32 GB suits always-on databases. - CPU: AMD Ryzen V1500B (4C/8T, 2.2 GHz) - RAM: 4 GB DDR4 ECC (32 GB max) - Bays: 4x SATA + 2x M.2 NVMe - Network: 2x 2.5GbE - Expansion: No PCIe slot; DX525 expansion unit only Pros: - Container Manager with Compose-based projects - ECC memory, expandable to 32 GB - DSM backup and management tools reduce how many containers you need Cons: - 4 GB base memory needs an upgrade for a real stack - No PCIe slot, so no 10GbE upgrade - No integrated graphics for hardware transcoding - M.2 pools and cache still need drives on Synology's compatibility list ### Best 10GbE: [UGREEN DXP4800 Plus](https://homelabpicks.com/go/ugreen-dxp4800) Built-in 10GbE and the highest memory ceiling in this roundup. The UGOS Pro Docker app manages images, containers, and Compose projects from the web interface. - CPU: Intel Pentium Gold 8505 (1P + 4E cores, 6 threads, up to 4.4 GHz) - RAM: 8 GB DDR5 (64 GB max) - Bays: 4x SATA + 2x M.2 NVMe - Network: 10GbE + 2.5GbE - Expansion: No PCIe slot Pros: - 10GbE built in - Memory expandable to 64 GB - Intel Quick Sync on the Pentium Gold 8505 Cons: - UGOS Pro is the youngest NAS OS here - 8 GB base memory needs an upgrade for a large stack - No PCIe slot ### Best 2-Bay: [QNAP TS-264](https://homelabpicks.com/go/qnap-ts-264) The TS-464's container platform in a two-bay box: the same quad-core N5095, 8 GB of memory, Container Station, and a PCIe slot for 10GbE. Two bays are the trade-off. - CPU: Intel Celeron N5095 (4C/4T, up to 2.9 GHz) - RAM: 8 GB DDR4 (two SODIMM slots, 16 GB max) - Bays: 2x SATA + 2x M.2 NVMe (PCIe 3.0 x1) - Network: 2x 2.5GbE - Expansion: PCIe Gen 3 x2 slot Pros: - Container Station with the same N5095 as the TS-464 - PCIe Gen 3 x2 slot for 10GbE - Dual 2.5GbE and HDMI 2.1 - Two M.2 NVMe slots Cons: - Only two drive bays - 16 GB official memory ceiling - QTS needs prompt patching and should not be exposed directly to the internet ## Comparison | Product | CPU | Base RAM | Max RAM | ECC | Networking | PCIe Slot | Container Software | | --- | --- | --- | --- | --- | --- | --- | --- | | [TerraMaster F4-424 Pro](https://homelabpicks.com/go/terramaster-f4-424-pro) (winner) | i3-N305 8C/8T | 32 GB DDR5 | 32 GB | No | 2x 2.5GbE | No | Docker Manager (TOS) | | [QNAP TS-464](https://homelabpicks.com/go/qnap-ts-464) | N5095 4C/4T | 8 GB DDR4 | 16 GB | No | 2x 2.5GbE | PCIe Gen 3 x2 | Container Station | | [Synology DS925+](https://homelabpicks.com/go/synology-ds925) | Ryzen V1500B 4C/8T | 4 GB DDR4 ECC | 32 GB ECC | Yes | 2x 2.5GbE | No | Container Manager | | [UGREEN DXP4800 Plus](https://homelabpicks.com/go/ugreen-dxp4800) | Pentium Gold 8505 5C/6T | 8 GB DDR5 | 64 GB | No | 10GbE + 2.5GbE | No | UGOS Pro Docker app | | [QNAP TS-264](https://homelabpicks.com/go/qnap-ts-264) | N5095 4C/4T | 8 GB DDR4 | 16 GB | No | 2x 2.5GbE | PCIe Gen 3 x2 | Container Station | Running Docker containers on a NAS turns a file server into a self-hosting box for Home Assistant, Immich, Jellyfin, Pi-hole, Nextcloud, and dozens of other always-on services. How many containers a NAS can carry comes down to three things: CPU cores, memory, and the quality of the container-management software. Many NAS units ship with 4 GB to 8 GB of RAM. That covers the NAS operating system plus a few light containers, but a serious stack needs 16 GB to 32 GB, so the memory ceiling matters as much as the base configuration. Core count decides how many busy containers can run at once without waiting on each other. This guide compares five NAS devices for Docker and self-hosting on CPU, memory capacity and ceiling, container software, and networking. --- ## Our Pick: TerraMaster F4-424 Pro The [TerraMaster F4-424 Pro](https://homelabpicks.com/go/terramaster-f4-424-pro) ships with 32 GB of DDR5 and an 8-core Intel Core i3-N305, so it can run a large container stack without a memory upgrade. - **CPU:** Intel Core i3-N305, 8 cores and 8 threads, up to 3.8 GHz - **Memory:** 32 GB DDR5 on one SODIMM, which TerraMaster lists as the maximum - **Storage:** 4x SATA bays + 2x M.2 NVMe (PCIe 3.0 x1) - **Network and video:** 2x 2.5GbE, HDMI 2.0b The i3-N305 has eight efficiency cores for concurrent services. An Immich machine-learning worker, Jellyfin using Quick Sync for a transcode, Home Assistant, Nextcloud, a PostgreSQL database, and a reverse proxy can run together with cores to spare. A quad-core chip like the TS-464's N5095 runs the same services, but with less headroom when several of them are busy at once. The 32 GB is the real differentiator. Immich with its machine-learning worker, Nextcloud with a database, and Jellyfin during a transcode can each want several gigabytes, and the NAS OS needs its share. On an 8 GB NAS, three heavy apps can push the system into swap; the F4-424 Pro has room for all of them. TOS includes Docker Manager in its App Center for pulling images, creating containers, and viewing logs. For more management options, install Portainer or Dockge as a container and manage the rest from there. Some owners go further and replace TOS with Proxmox, running Docker inside an LXC container. Know the cost first: TerraMaster's FAQ says installing another operating system voids the warranty and ends technical support. If you want Proxmox, our [home lab starter guide](https://homelabpicks.com/guides/home-lab-starter-guide/) covers running it on separate hardware. The other trade-offs: there is no PCIe slot for 10GbE, and TOS has a thinner app catalog than DSM or QTS for backup, photo, and surveillance duties. --- ## Best Value: QNAP TS-464 The [QNAP TS-464](https://homelabpicks.com/go/qnap-ts-464) pairs the most flexible container software in this guide with a quad-core Intel CPU and a PCIe expansion slot. - **CPU:** Intel Celeron N5095, 4 cores and 4 threads, up to 2.9 GHz - **Memory:** 8 GB DDR4 in two SODIMM slots, 16 GB maximum (QNAP) - **Storage:** 4x SATA bays + 2x M.2 NVMe (PCIe 3.0 x1) - **Network and video:** 2x 2.5GbE, one PCIe Gen 3 x2 slot, HDMI 2.1 **Container Station** is the standout. QNAP lists support for Docker, LXD system containers, and Kata containers (lightweight VMs), all from one interface. LXD means you can run a full Ubuntu or Debian system beside your Docker containers for services that expect a traditional Linux host. The stock 8 GB handles a moderate stack. When you outgrow it, QNAP's official maximum is 16 GB across the two SODIMM slots. That covers a broad self-hosted set: Jellyfin, Home Assistant, Pi-hole, Nextcloud, Vaultwarden, Paperless-ngx, a reverse proxy, Uptime Kuma, and Gitea. Intel Quick Sync helps media containers. Jellyfin and Plex can hand transcodes to the N5095's media engine instead of the CPU cores, which leaves CPU time for the rest of the stack. For Plex-specific planning, see our [best NAS for Plex](https://homelabpicks.com/nas/best-nas-for-plex/) guide. The PCIe Gen 3 x2 slot is the other reason to pick it. A 10GbE card removes the network as a bottleneck when several containers move large files at once. Among these five, only the TS-464 and the two-bay TS-264 have a PCIe slot. The limitations: 16 GB is the ceiling, so memory-hungry apps like Immich use up a large share of it. QNAP also needs disciplined security. Keep QTS updated, reach it remotely through a VPN rather than exposing it to the internet, and disable UPnP. --- ## Best Software: Synology DS925+ The [Synology DS925+](https://homelabpicks.com/go/synology-ds925) doesn't win on raw hardware, but Container Manager on DSM is our preferred Docker interface, and it is the only pick with ECC memory. - **CPU:** AMD Ryzen V1500B, 4 cores and 8 threads, 2.2 GHz - **Memory:** 4 GB DDR4 ECC, expandable to 32 GB - **Storage:** 4x SATA bays + 2x M.2 NVMe - **Network:** 2x 2.5GbE; no PCIe slot **Container Manager** runs multi-container projects from Compose files through its Project dashboard, so you can upload or paste a `docker-compose.yml` and manage the whole stack from DSM. The V1500B's eight threads handle a moderate stack comfortably; the 4 GB base memory is the part to upgrade first. ECC memory corrects single-bit memory errors that could otherwise corrupt a database or crash a long-running container. The DS925+ takes up to 32 GB of ECC DDR4. The broader DSM ecosystem also reduces how many containers you need. Active Backup for Business handles PC and server backups, Synology Drive covers file sync, and Synology Photos covers basic photo management, so a Synology owner may never deploy Duplicati, Nextcloud, or Immich. Know the limits. The DS925+ has no PCIe slot, so it cannot take Synology's 10GbE card, and networking tops out at its two 2.5GbE ports. Since DSM 7.3 (October 2025), 2025 Plus, Value and J models accept third-party 3.5-inch HDDs and 2.5-inch SATA SSDs; M.2 storage pools and cache still need drives on Synology's compatibility list. --- ## Best 10GbE: UGREEN DXP4800 Plus The [UGREEN DXP4800 Plus](https://homelabpicks.com/go/ugreen-dxp4800) has built-in 10GbE and the highest memory ceiling in this roundup. - **CPU:** Intel Pentium Gold 8505, 1 performance core + 4 efficiency cores, 6 threads, up to 4.4 GHz - **Memory:** 8 GB DDR5, expandable to 64 GB (UGREEN) - **Storage:** 4x SATA bays + 2x M.2 NVMe - **Network and video:** 10GbE + 2.5GbE, 4K HDMI The Pentium Gold 8505's performance core helps latency-sensitive services such as databases and reverse proxies, while background containers spread across the four efficiency cores. The chip also has Intel Quick Sync for media containers. The 64 GB ceiling is the highest here: double the DS925+ and four times the TS-464. Plan to upgrade from 8 GB before deploying a large stack. Built-in 10GbE removes the need for a PCIe card. If your network has a [10GbE switch](https://homelabpicks.com/networking/best-10g-switch/), containers that serve large files, such as Nextcloud, Jellyfin, and SMB shares, benefit immediately. The extra 2.5GbE port can carry a separate management network. **The UGOS Pro Docker app** installs from the App Center and manages images, containers, networks, and Compose projects from the web interface. The trade-off is software maturity: UGOS Pro is the newest NAS OS in this guide, with a thinner app catalog and fewer community guides than QTS or DSM. --- ## Best 2-Bay: QNAP TS-264 The [QNAP TS-264](https://homelabpicks.com/go/qnap-ts-264) is the TS-464's container platform in a two-bay chassis: Container Station, a quad-core N5095, and a PCIe slot. - **CPU:** Intel Celeron N5095, 4 cores and 4 threads, up to 2.9 GHz - **Memory:** 8 GB DDR4 in two SODIMM slots, 16 GB maximum (QNAP) - **Storage:** 2x SATA bays + 2x M.2 NVMe (PCIe 3.0 x1) - **Network and video:** 2x 2.5GbE, one PCIe Gen 3 x2 slot, HDMI 2.1 You get the same Container Station software and the same CPU as the TS-464, so the container guidance above applies: the stock 8 GB handles a moderate stack, and the two SODIMM slots take up to 16 GB. The PCIe slot takes a 10GbE card or other expansion later, and the two M.2 slots take SSDs for caching or a small fast pool. The trade-off is storage: two bays mean a mirror, so capacity grows only by replacing both drives. If you expect your data to grow quickly, start with the TS-464, or see our [best 4-bay NAS](https://homelabpicks.com/nas/best-4-bay-nas/) guide. --- ## How to Choose: Buying Criteria ### RAM: The Most Important Docker Spec Memory decides how many containers you can run at once. As a rough planning guide: | Stack Size | Containers | RAM | Example Stack | |---|---|---|---| | **Starter** | 3–5 | 8 GB | Pi-hole, Home Assistant, Nginx Proxy Manager, Watchtower | | **Moderate** | 8–12 | 16 GB | Add Jellyfin, Nextcloud, Vaultwarden, Uptime Kuma, Gitea | | **Heavy** | 15–20 | 32 GB | Add Immich, PostgreSQL, Paperless-ngx, Grafana | | **Power User** | 20–30+ | 32–64 GB | Multiple databases, AI/ML services, VMs alongside containers | The most common mistake is buying a 4 GB NAS and assuming Docker will scale. It runs, but a few containers use up the headroom and the system starts swapping. Budget for a memory upgrade on every pick except the TerraMaster. | NAS | Ships With | Official Maximum | |---|---|---| | TerraMaster F4-424 Pro | 32 GB DDR5 | 32 GB | | QNAP TS-464 | 8 GB DDR4 | 16 GB | | Synology DS925+ | 4 GB DDR4 ECC | 32 GB | | UGREEN DXP4800 Plus | 8 GB DDR5 | 64 GB | | QNAP TS-264 | 8 GB DDR4 | 16 GB | Memory prices move quickly, so check current module prices before you budget an upgrade. ### CPU Cores: More Matters More Than Clock Speed Docker containers share CPU time. A dual-core CPU with two busy containers has no headroom left; an 8-core CPU with the same load still has most of its cores free. The core and thread counts in this guide: 1. **TerraMaster F4-424 Pro (i3-N305, 8C/8T):** the most headroom for CPU-heavy services such as Immich's machine-learning worker and OCR, alongside light ones. 2. **Synology DS925+ (Ryzen V1500B, 4C/8T):** eight threads for a moderate stack, especially when DSM's own apps replace some containers. 3. **UGREEN DXP4800 Plus (Pentium Gold 8505, 5C/6T):** one fast performance core plus four efficiency cores. 4. **QNAP TS-464 and TS-264 (Celeron N5095, 4C/4T):** suitable for several home services with moderate CPU use. For containers that do OCR, indexing, or software transcoding, having a free core matters more than a few hundred megahertz of clock speed. ### Container Management Software **QNAP Container Station (TS-464, TS-264):** The most versatile option, with Docker, LXD, and Kata containers in one interface (Kata requires an x86 NAS, per QNAP). The best choice if you want a GUI-first experience with system containers too. **Synology Container Manager (DS925+):** Our preferred interface. Compose-based projects run from the DSM interface, and DSM handles accounts, backups, and notifications around them. It sticks to Docker, without QNAP's LXD or Kata support. **TerraMaster Docker Manager (F4-424 Pro):** Functional basics: pull images, create containers, view logs. Many owners add Portainer and manage everything from there. **UGOS Pro Docker app (DXP4800 Plus):** Manages images, containers, networks, and Compose projects from the web interface. It is newer than QNAP's and Synology's tools, with a smaller body of community guides. ### Networking for Containers For most home setups, 2.5GbE is plenty: a dozen containers serving web interfaces barely touch the link. 10GbE matters when containers move large data, such as Nextcloud syncing big folders, Jellyfin streaming 4K remuxes to several clients, or NFS-mounted volumes used by other machines. The UGREEN DXP4800 Plus includes 10GbE. The QNAP TS-464 and TS-264 can add it through their PCIe slots. The DS925+ and TerraMaster F4-424 Pro cannot. Bridge networking works on all five. Macvlan, which gives containers their own LAN addresses, may need command-line setup depending on the platform. --- ## Bottom Line The **[TerraMaster F4-424 Pro](https://homelabpicks.com/go/terramaster-f4-424-pro)** is the best NAS for Docker. With 32 GB of DDR5 and an 8-core i3-N305, it runs a large stack on day one without an upgrade. Just note that TerraMaster voids the warranty if you replace TOS. For the best balance of container software and expansion, the **[QNAP TS-464](https://homelabpicks.com/go/qnap-ts-464)** gives you Container Station's Docker, LXD, and Kata support plus a PCIe slot for 10GbE. Upgrade to its 16 GB maximum as the stack grows. If ease of administration and ECC memory matter most, the **[Synology DS925+](https://homelabpicks.com/go/synology-ds925)** runs Container Manager on DSM with up to 32 GB of ECC memory. It has dual 2.5GbE but no PCIe or 10GbE upgrade path. For built-in 10GbE and the highest memory ceiling, the **[UGREEN DXP4800 Plus](https://homelabpicks.com/go/ugreen-dxp4800)** delivers, with the caveat that UGOS Pro is the youngest platform here. If two bays are enough, the **[QNAP TS-264](https://homelabpicks.com/go/qnap-ts-264)** gives you the TS-464's CPU, Container Station, and PCIe slot in a smaller box. Whichever you choose, pair it with quality storage. See our [best hard drives for NAS](https://homelabpicks.com/drives/best-hard-drive-for-nas/) guide, and our [full NAS comparison](https://homelabpicks.com/nas/best-nas-home-lab/) for the broader picture. ## FAQ ### Can you run Docker on a NAS? Yes. QNAP runs it through Container Station, Synology through Container Manager, TerraMaster through Docker Manager, and UGREEN through the Docker app in UGOS Pro. x86 models run the widest range of images; ARM models need images published for ARM64. ### How much RAM do I need for Docker on a NAS? As a rough planning guide, 8 GB covers a handful of light containers such as Pi-hole, Vaultwarden, and a reverse proxy alongside the NAS OS. 16 GB suits a mixed stack, and 32 GB leaves room for memory-hungry apps such as Immich, Nextcloud, and databases. ### What is the best NAS for Docker in 2026? The TerraMaster F4-424 Pro, because it ships with 32 GB of DDR5 and an 8-core i3-N305. For less money and more flexible container software, the QNAP TS-464 runs Container Station and can be upgraded to 16 GB. ### Is Synology or QNAP better for Docker? QNAP Container Station supports more container types: Docker, LXD, and, on x86 models, Kata. Synology Container Manager is simpler and runs Compose projects from the DSM interface. Both handle a typical home-lab stack. ### Can I run Portainer on a NAS? Yes. Portainer runs as a container on any NAS with Docker. It is optional on QNAP, Synology, and UGREEN, which all include their own container interfaces, and it is a common first container on TerraMaster. ## Sources - [TerraMaster F4-424 Pro specifications](https://www.terra-master.com/pages/f4-424-pro-specification) (accessed 2026-09-29) - [QNAP TS-464 hardware specifications](https://www.qnap.com/en-us/product/ts-464/specs/hardware) (accessed 2026-09-29) - [Synology DS925+ specifications](https://www.synology.com/en-global/products/DS925+) (accessed 2026-09-29) - [UGREEN NASync DXP4800 Plus product page](https://ai.ugreen.com/products/ugreen-nasync-dxp4800-plus-nas-storage) (accessed 2026-09-29) - [QNAP TS-264 hardware specifications](https://www.qnap.com/en-us/product/ts-264/specs/hardware) (accessed 2026-09-30) - [Intel Pentium Gold 8505 specifications](https://www.intel.com/content/www/us/en/products/sku/226262/intel-pentium-gold-processor-8505-8m-cache-up-to-4-40-ghz/specifications.html) (accessed 2026-09-30) - [QNAP Container Station](https://www.qnap.com/en/software/container-station) (accessed 2026-09-30) - [Synology Container Manager](https://www.synology.com/en-us/dsm/feature/docker) (accessed 2026-09-30) - [How to use Docker and Docker Compose on UGREEN NAS](https://ai.ugreen.com/blogs/knowledge/docker-docker-compose-ugreen-nas) (accessed 2026-09-29) - [TerraMaster FAQ on installing other operating systems](https://www.terra-master.com/blogs/faq/can-other-versions-of-linux-or-other-open-source-nas-systems-be-installed-on-my-tnas-device) (accessed 2026-09-30) - [Synology DSM 7.3 release announcement](https://www.synology.com/en-global/company/news/article/dsm73) (accessed 2026-09-29)
