Overview

The Synology DS923+ is the NAS that ends most home-lab build-vs-buy debates. For $599 (chassis only, drives extra) you get a 4-bay desktop NAS with an AMD Ryzen R1600 CPU, ECC RAM support, two NVMe cache slots, an optional PCIe slot for a 10GbE upgrade, and DSM 7.2 — which remains the best NAS operating system shipping in 2026, full stop. The hardware is two years old at this point; the software is the reason it's still the right pick.

The DSM advantage is hard to overstate until you've used the alternatives. Plex Media Server installs from the Synology Package Center in two clicks. Docker runs natively. Surveillance Station handles 8 IP cameras with motion zones and hardware-accelerated recording. Active Backup for Business backs up Proxmox VMs, Hyper-V, VMware, and individual workstations to the same DS923+ with deduplication. Hyper Backup pushes encrypted backups to Backblaze B2 on a schedule. None of this requires Linux package juggling — it's all in the GUI, and it's all reliable enough to run unattended for years.

The DIY alternative — a TrueNAS Scale build on a custom chassis — gives you more raw flexibility and lower per-TB cost for large arrays. It also gives you the privilege of being your own support engineer. For a home lab where the NAS holds your Proxmox backups, your Plex media, and your family photos, the right question isn't 'can I build it cheaper' — it's 'do I want to be on-call for it.' Most self-hosters, after building TrueNAS once, buy a Synology the next time around.

The DS923+ is the price-vs-features sweet spot in the Synology lineup. The DS224+ ($299) is too small for serious media + backup duty. The DS1522+ ($699) gives you 5 bays for $100 more if you'll grow there. The DS923+ at $599 hits the right balance for a first serious home-lab NAS.

Pros & Cons

Why DSM 7.2 Beats TrueNAS Scale for Most Home Labs

TrueNAS Scale is genuinely excellent. It's open source, runs on commodity x86 hardware, supports ZFS natively with all the snapshot and replication features, and has a friendlier UI than the old FreeNAS days. None of that changes the fact that for a typical home-lab use case, DSM 7.2 wins on time-to-running and reliability.

Consider the Plex install. On DSM: open Package Center, search 'Plex', click Install, log in, scan library. Done in 10 minutes. On TrueNAS Scale: install the Plex chart from the catalog, configure persistent storage volumes, set the PUID/PGID for media access, configure the dataset permissions to match, troubleshoot why hardware transcoding isn't detecting your iGPU, edit the chart values YAML to mount /dev/dri, restart the pod. Hour and a half if you know what you're doing. Three hours if you don't.

This pattern repeats for every common service. Docker on DSM: Container Manager UI, point-and-click. Docker on TrueNAS: Helm charts and YAML. Surveillance for cameras on DSM: Surveillance Station with motion zones in a GUI. Surveillance on TrueNAS: Frigate or Shinobi in a container, with config files. Backups on DSM: Active Backup for Business with a VM agent and one-click restore. Backups on TrueNAS: rsync targets, or Proxmox Backup Server in a separate container.

The TrueNAS advantage is ZFS at scale (10TB+ arrays where the integrity-checking matters), and the lack of vendor lock-in. The DSM advantage is everything else. For a home lab where the NAS is one of 5-10 services you're running and you don't want to spend a weekend a quarter maintaining it, DSM is the answer.

One real trade-off: the DS923+ runs Btrfs, not ZFS. Btrfs is fine for the home-lab tier (snapshots, checksums, send/receive), but it's not as battle-tested at scale as ZFS. If you're planning a 6-bay+ array with 8TB+ drives, the ZFS resilver behavior under disk failure matters more, and TrueNAS becomes the better pick. Up to ~30TB usable, Btrfs on DSM is genuinely fine.

The 10GbE Upgrade Path — When and How to Actually Use It

The DS923+'s open PCIe slot is the feature that separates it from the DS923 (no plus) and most 4-bay competitors. With the optional E10G18-T1 card ($179, 10GBASE-T copper) installed, the NAS exposes a third LAN interface running at 10G full-duplex. Combined with a 10G-capable switch like the MikroTik CRS326 ($219 with S+RJ10 module), you get a 10GbE storage backbone for the home lab.

The honest question: is this upgrade actually worth it for typical home use?

For pure media streaming (Plex transcoded to phones, tablets, TVs), the answer is no. Plex streams are 5-15Mbps each; gigabit handles 60+ concurrent streams. The DS923+ on its built-in dual gigabit LAN ports is more than sufficient.

For Proxmox backup operations, the answer is absolutely yes. Backing up a 100GB VM disk over gigabit takes ~20 minutes (capped at 110MB/s). Over 10G it takes 2-3 minutes (capped by the Synology's two-disk write speed of ~500MB/s on CMR drives). If you're backing up 5 VMs nightly, that's the difference between a 100-minute backup window and a 15-minute window.

For large file moves (video editing, photo library imports, ISO storage), 10G changes the workflow. Editing a 4K video file directly off the NAS over 10G is responsive; over gigabit it's unusable.

My recommendation: skip the 10GbE card on day one. Run the DS923+ on its built-in dual gigabit ports for the first 3-6 months. If you find yourself waiting on backups or file transfers regularly, then add the card ($179 + $59 SFP+ module = $238). If you're only using the NAS for Plex and basic file storage, you'll never feel the gigabit limit.

The Right Drive Setup — IronWolf vs Synology HAT3300 vs WD Red

Drive choice is the second biggest decision after the chassis itself, and Synology has made it more complicated than it needs to be.

Synology DSM 7.2 includes a 'Drive Compatibility List' that warns you when non-Synology-branded drives are installed. The drives still work — you're not blocked from using them — but DSM shows a yellow warning and certain features (like specific cache acceleration profiles) are restricted to Synology-branded drives. This was a controversial change starting with DSM 7.0 and continues to annoy users in 2026.

Three drive paths:

Seagate IronWolf 8TB (ST8000VN004, ~$200/drive): proven, reliable, full DSM compatibility. The warnings persist but every feature works. This is what I run in my own DS923+. Four drives × $200 = $800 for the drive bay alone.

Synology HAT3300-8T (~$280/drive): branded as 'Synology Drives', actually rebranded Toshiba MG09 enterprise drives with Synology firmware. Zero DSM warnings, full feature access including the optional drive health analytics. Premium of ~$320 for a 4-bay array. The price-per-TB premium is real; the convenience is also real.

WD Red Plus 8TB (WD80EFZZ, ~$190/drive): also fine, also triggers the same compatibility warning as IronWolf. Slightly quieter than IronWolf. Same 3-year warranty.

Avoid: SMR (shingled magnetic recording) drives. The WD Red (non-Plus) line uses SMR, which is catastrophic for ZFS/Btrfs resilver operations — a single drive failure can take 2-3 days to rebuild and the array's write performance during the rebuild is terrible. CMR (conventional magnetic recording) only. Both IronWolf and Red Plus are CMR; the basic WD Red is SMR. Check the part number carefully.

My recommendation: four Seagate IronWolf 8TB in SHR (Synology Hybrid RAID, similar to RAID 5 in protection but more flexible for mixed drive sizes) gives you ~21TB usable, single-disk failure tolerance, and costs $800 in drives. Total system cost: $599 chassis + $800 drives = $1,399 for a serious home-lab NAS.

Plex, Proxmox Backup, and Docker — The Three Workloads That Justify the DS923+

If you're going to spend $1,400 on a NAS build, it should be earning its keep. The DS923+ in a typical home lab runs three concurrent workloads, all of them simultaneously.

Plex Media Server: install from Package Center, point at your media folder, you're done. The Ryzen R1600 CPU handles 2-3 simultaneous 1080p H.264 transcodes or 1-2 4K HEVC transcodes (requires Plex Pass for hardware transcoding to enable, even on Synology — the Ryzen R1600 has no integrated GPU, so all transcoding is CPU-bound). For most home labs with mostly direct-play clients (modern Smart TVs, Apple TVs, phones), the transcoding ceiling is rarely hit. If you serve more than 4 simultaneous streams with frequent transcoding, look at a Beelink mini-PC running Plex separately with iGPU acceleration.

Active Backup for Business: install the Synology agent on each Proxmox node (it runs as a VM with the PBS agent), configure a backup schedule for each VM, point the target at the DS923+. Deduplication is global across all backups, so backing up 10 VMs that share an Ubuntu base image only stores the base once. Restore is one-click to original or alternate location. This single feature is why a lot of Proxmox users buy a Synology specifically.

Docker via Container Manager: the DS923+ runs Docker natively via the Container Manager UI. Common services: Pi-hole (ad-blocking DNS), Vaultwarden (self-hosted Bitwarden), Jellyfin (alternative to Plex), Home Assistant, n8n. The 4GB of RAM in the base config is tight if you run more than 3-4 containers; upgrade to 8GB ($40 for an unofficial-compatible SODIMM) or 16GB ($80) if you'll lean on Docker. Synology officially supports up to 32GB ECC but only their branded modules are 'supported' — unofficial RAM works fine in practice.

All three workloads run concurrently on a stock R1600 + 4GB RAM build at about 40% CPU utilization average. Adding 16GB RAM and the DS923+ is comfortably handling everything a typical home lab throws at it.

DS923+ vs DS224+ vs DS1522+ — Which Synology to Actually Buy

Synology's lineup creates analysis paralysis. Three honest decision points.

DS224+ ($299, 2-bay): the wrong NAS for almost any home lab. Two bays means RAID 1 only, which gives you single-drive failure protection but only ~8TB usable from two 8TB drives. Twelve months later you'll be deleting old TV shows to make space. Skip it unless your only use case is photo backup and a single Plex library.

DS923+ ($599, 4-bay): the right NAS for ~80% of home labs. SHR gives you ~21TB usable from 4x8TB drives with single-disk failure tolerance, scaling up to ~36TB with 4x12TB drives. The PCIe 10GbE slot is genuinely useful even if you don't install it on day one — it's a real upgrade path. NVMe cache slots help with random-IO workloads (Docker volumes, VM datastores). Best balance of features-per-dollar in the Synology Plus line.

DS1522+ ($699, 5-bay): worth the extra $100 only if you know you'll fill 5 bays within 12 months. The fifth bay extends usable storage by ~25% in SHR mode, which is real value if you're a media hoarder or running a serious Proxmox Backup target. Same PCIe slot, same RAM, same CPU as the DS923+ — the only differences are the extra bay and a slightly larger chassis.

DS1821+ ($1,049, 8-bay): for the home lab that's outgrowing 5 bays already. At this point you're approaching diminishing returns vs a custom TrueNAS build, but you keep the DSM advantage. Worth it if you've already lived the Synology workflow and don't want to switch.

My strong call: DS923+ for a first serious home-lab NAS. Upgrade to DS1522+ only if you have a confirmed 5-bay use case. Don't downgrade to DS224+ — you'll regret it within a year.
