What Is the Lenovo M720Q 6-Bay NAS Build?

The phrase “built 6bay 10gbps lenovo” has been circulating r/homelab for good reason — this is one of those rare builds where the math just works. The Lenovo ThinkCentre M720Q is a Tiny-form-factor business PC originally designed for enterprise desktops. It ships with an Intel 8th or 9th gen Core processor (commonly an i5-8500T or i7-8700T), supports up to 64GB DDR4, and has a single PCIe x16 slot running at x4 electrical — the key hardware hook for this entire build.

The expansion path relies on three components sourced affordably from the grey market and Amazon. First, a 6×2.5-inch SATA bay kit designed specifically for the M720Q and M920Q chassis — this includes a SATA backplane, cooling fans, power input wiring, an M.2 to 6-port SATA adapter card, and all necessary cables, available for approximately $55. Second, a PCIe riser card at roughly $8 that provides a 12V power rail and an additional NVMe slot. Third, an Intel X550-T2 dual-port 10GbE NIC for approximately $31 on the used market. Total expansion cost: around $94.

The genuine surprise in this build — and the detail that makes it genuinely interesting — is that the M720Q’s single PCIe slot simultaneously drives both the X550-T2 NIC and an NVMe SSD via the riser card without any BIOS bifurcation configuration. Officially, bifurcation is not supported. In practice, it just works. Based on real-world testing across multiple community builds, this behavior appears consistent across M720Q units running recent BIOS versions, though it is worth noting this is not a guaranteed or officially supported feature.

Price Comparison: M720Q vs. the Alternatives

Price is where the M720Q build creates the most separation from the competition. A used M720Q with an i5-8500T and 16GB RAM typically trades between $120 and $180 on eBay and Amazon in 2026. Add the $94 in expansion hardware and you are looking at a fully capable 6-bay 10GbE NAS for $214–$274 before drives.

The Synology DS923+ retails at $599–$649 and delivers four bays with 2.5GbE onboard — you need to purchase a separate 10GbE expansion card (the E10G22-T1-Mini) for an additional $80–$100 to match the M720Q’s networking spec. That brings the Synology to $700+ before a single drive is installed. The QNAP TS-464 sits at $499–$549 with 2.5GbE base networking. The Terramaster F4-424 Pro is the most competitive appliance at $549–$599 with dual 10GbE built in, but it still costs roughly 2x the M720Q build.

Community consensus on r/homelab is clear: if you are comfortable installing TrueNAS SCALE or Unraid and do not need vendor warranty support, the M720Q build is the most cost-effective path to genuine 10GbE NAS performance in a compact footprint in 2026.

Performance: Real-World Throughput and Benchmarks

In a real home lab setup with the M720Q running TrueNAS SCALE 24.10 and a 4-drive ZFS RAIDZ1 array of 2TB 2.5-inch SATA SSDs, sequential read throughput over 10GbE measured 940–970 MB/s — effectively saturating the link. Sequential write came in at 820–860 MB/s. The Intel X550-T2 handles these transfers without dropping frames, though CPU utilization on the i5-8500T climbs to 35–45% during sustained 10GbE transfers due to the lack of hardware offload at the NAS OS level in some configurations.

The Synology DS923+ with its AMD Ryzen R1600 dual-core processor and the 10GbE expansion card peaks at approximately 750–800 MB/s sequential read in DSM 7.2, constrained by the R1600’s single-threaded performance during heavy ZFS equivalent (Btrfs) operations. The Terramaster F4-424 Pro with its Intel Celeron N5105 and dual 10GbE pulls roughly 850–900 MB/s sequential read under TOS 5, making it the strongest appliance competitor. The DIY N100 build tops out at 280–310 MB/s over its 2.5GbE interface — a hard ceiling that no software optimization can overcome.

For plex transcoding alongside NAS duties, the M720Q’s i5-8500T or i7-8700T handles 3–4 simultaneous 1080p software transcodes at under 60% CPU load, a workload that pushes the Synology DS923+ to 85–95% utilization and causes occasional dropped frames on the fourth stream.

Power Draw: Which NAS Costs Less to Run?

Power consumption is a meaningful operating cost for any always-on NAS. The M720Q system with six 2.5-inch SATA SSDs, the X550-T2 NIC active, and moderate CPU load measures 38–52W at the wall. At idle with drives spun down (SSDs don’t spin, but in low-power states), the system sits at 18–22W.

The Synology DS923+ with four drives idles at 28–34W and peaks at 55–65W under load — comparable total consumption but with fewer bays and lower network throughput. The QNAP TS-464 is similar at 30–60W depending on drive count and activity. The N100 mini PC NAS is the clear efficiency winner at 8–18W total, but its 2.5GbE ceiling makes it unsuitable for high-throughput use cases. The Terramaster F4-424 Pro draws 25–55W — slightly more efficient than the M720Q build at equivalent load.

One important thermal note: the Intel X550-T2 NIC generates substantial heat under 10Gbps sustained load. In the M720Q’s compact chassis, junction temperatures on the X550-T2 can reach 85–92°C without additional airflow. A 40mm Noctua fan zip-tied to direct airflow across the card keeps temperatures below 78°C under continuous transfer — this is not an optional upgrade for 24/7 operation.

Software Support and Ecosystem

Software is where dedicated NAS appliances earn their premium. Synology’s DSM 7.2 is genuinely excellent — Active Backup for Business, Surveillance Station, Hyper Backup, and the broader package ecosystem represent years of polish that TrueNAS and Unraid cannot fully replicate out of the box. If you need a NAS that a non-technical family member can navigate, DSM wins without contest.

TrueNAS SCALE on the M720Q is powerful but demands more from the user. ZFS datasets, jail configuration, and SMB share permissions require real engagement. The payoff is flexibility: running Docker containers, VMs via KVM, and Kubernetes apps alongside NAS duties on the same hardware is genuinely capable on the M720Q’s i5/i7 processor. Unraid offers a middle ground with its more approachable UI and mixed drive size support, which is valuable when building out storage incrementally.

QNAP’s QTS has improved significantly but carries a legacy reputation for security vulnerabilities that the community has not fully forgiven. Terramaster’s TOS 5 is competent but the ecosystem depth is thinner than Synology or QNAP. For home lab users already running self-hosted services, the M720Q running TrueNAS SCALE integrates naturally into an existing Docker and network stack — something worth considering if you are already managing infrastructure like the setups covered in our OpenNMC open-source network card guide.

Ease of Setup: Plug-and-Play vs. DIY Reality

Honesty matters here. The M720Q NAS build is not plug-and-play. The 6-bay kit requires careful cable routing in a very tight chassis. The M.2 to 6-port SATA adapter needs to seat properly in the M.2 slot while the riser card occupies the PCIe slot — there is not a lot of clearance. Plan for 2–3 hours of physical assembly and another 1–2 hours of TrueNAS or Unraid configuration. If you have never configured a ZFS pool or set up SMB shares from scratch, add another evening of learning.

The Synology DS923+ takes 20 minutes from box to operational NAS. Drive installation is tool-free, DSM setup wizard is genuinely idiot-proof, and Synology’s documentation is among the best in the industry. For someone who wants storage that works and nothing more, the appliance path is legitimate.

The N100 mini PC NAS build is similarly DIY but simpler than the M720Q — fewer components, no riser card complexity, though the 2.5GbE ceiling is a long-term frustration. The Terramaster F4-424 Pro splits the difference: physical setup is appliance-simple, but TOS 5 configuration is more complex than DSM.

Budget Pick vs. Premium Pick

Budget Pick: Lenovo M720Q DIY NAS Build

If you are comfortable with a few hours of assembly and the TrueNAS SCALE learning curve, the M720Q build is the undisputed budget champion. At $250–$350 all-in for a 6-bay 10GbE NAS with a genuine 6-core processor, there is nothing on the market that competes dollar-for-dollar. The community support on r/homelab is extensive, the hardware is proven, and the performance numbers are genuinely impressive. Add the Noctua NF-A4x20 for thermal management and you have a build that can run 24/7 without concern.

Premium Pick: Synology DS923+

For home lab users who want zero ongoing maintenance friction — or who are deploying storage for a household where others need to access and manage files — the Synology DS923+ justifies its price premium through DSM’s software maturity. Active Backup for Business alone replaces paid backup software licenses. The 5-year warranty means you are not gambling on refurbished hardware. If budget is not the primary constraint and software reliability matters most, the DS923+ is the premium pick without hesitation. Just budget for the 10GbE expansion card if you need full network throughput.
