He says the RD440 pulled about 200–300W at the wall, compared with roughly 40–45W for the UGREEN system, and estimates the change saves him more than $220 a year on electricity. Those are figures from his own setup, not a controlled comparison or a promise of what another home server will save.
The trade-off matters: his old server had 12 drive bays, while one UGREEN model discussed in the coverage, the DXP4800 GT, has four SATA bays. Campanale’s account does not clearly identify which exact UGREEN unit replaced the RD440, so the DXP4800 GT should not be treated as the confirmed replacement.

What Campanale replaced—and what he gained
Campanale says he bought a used Lenovo ThinkSystem RD440 for a little over $300 and used it for nearly six years. It had two decade-old Xeon processors, totaling 12 cores and 24 threads, plus 64GB of DDR3 ECC memory. It was a 12-bay rack server, not a generic example of every older Xeon machine.

He says he moved to UGREEN NAS hardware in June 2026 and calls the decision his best one. In the same article, he describes the DXP4800 GT he reviewed earlier that year as outperforming the old server despite having fewer drive bays. He also says he had access to a UGREEN iDX6011 Pro. The article does not unambiguously tie the replacement measurements to one exact model. Campanale’s account, published by How-To Geek and republished by Yahoo Tech, is a personal comparison rather than a same-workload lab test.

How much power did the two systems use?
Campanale reports that his RD440 drew around 200–300W from the wall, while his UGREEN system drew around 40–45W. He estimates that the lower draw saves him more than $220 per year in electricity. The dollar estimate depends on his devices, usage, local electricity rate, and the period over which he calculated it; it is not a universal saving for replacing a Xeon server with any NAS.
The available account does not establish a controlled comparison with matching drives, workload, network activity, or measurement conditions. To estimate your own running cost, measure the complete system at the wall during the states you actually use—such as idle, file transfers, and background jobs—and apply your electricity rate to the measured consumption and hours. Include attached drives and networking equipment if they are part of the always-on setup.

Why published NAS power figures are not a direct comparison
UGREEN publishes separate figures for the DH2300, a different two-bay model: 13.72W during drive access and 3.304W during drive hibernation. The company says those lab measurements used a Seagate 2TB hard drive and cautions that actual consumption varies with the drives, network activity, background tasks, cooling, and settings. They are not measurements of Campanale’s UGREEN system or the DXP4800 GT. See UGREEN’s DH2300 specifications and measurement caveat.

Lower power is only one part of the choice. The RD440 offered 12 drive bays, which can suit a large or mixed-drive storage pool. A smaller NAS may be simpler to fit into a home setup, but it can limit how many drives you install and how you expand later.

| Lenovo ThinkSystem RD440 in Campanale’s account | 12 drive bays; two older Xeons totaling 12 cores/24 threads; 64GB DDR3 ECC RAM | Campanale reports 200–300W at the wall. His used purchase price was a little over $300. |
| UGREEN NASync DXP4800 GT, as listed in TechRadar’s 2026 review | Four SATA bays and two Gen3 x2 M.2 NVMe slots; review lists up to 144TB combined SATA and NVMe capacity | Dual 10GbE and UGOS Pro. The review notes single-channel RAM as a limitation. |
| UGREEN NASync DH2300, per UGREEN’s specifications | Two SATA bays; up to 64TB raw capacity with two 32TB drives; 4GB LPDDR4X | 1GbE; RAID 0/1. Its published power figures are model- and lab-specific, not the figures in Campanale’s comparison. |
| UGREEN NASync DH4300 Plus, per Android Central’s review | Four bays; up to 128TB raw capacity; 8GB soldered memory; no M.2 storage | 2.5GbE; the review notes no Plex hardware transcoding. |
These models are not interchangeable. The DXP4800 GT’s four SATA bays and two M.2 slots offer a different storage layout from the two-bay DH2300 or four-bay DH4300 Plus. The DH4300 Plus’s lack of M.2 storage and hardware transcoding may matter for particular applications. Read the model-specific details in TechRadar’s DXP4800 GT review and Android Central’s DH4300 Plus review.
Performance depends on the workload and network
A file server, a container host, and a machine that processes or transcodes media do not place identical demands on hardware. The RD440’s processor, memory, expansion options, and operating environment may be useful for jobs beyond basic file storage. A NAS can be a better fit for centralized storage without necessarily replacing every server role; check that the specific model and software support the applications you rely on.

TechRadar measured 272.96MB/s read and 268.35MB/s write on the DXP4800 GT over its 2.5GbE test network, and reported higher speeds after adding 10GbE networking. Those are the reviewer’s results, not a head-to-head test against Campanale’s RD440. The review’s faster-network setup used a 10GbE switch and a USB4-to-10GbE adapter; dual 10GbE ports on a NAS do not by themselves make other devices or the network path 10GbE-capable.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Count the whole cost, not just the enclosure
The RD440’s reported purchase price was a little over $300, but that figure alone does not capture its ongoing electricity cost or the drives and maintenance associated with a particular installation. A NAS enclosure’s price is also not the full cost of a working system: some units are sold without drives, and a higher-speed network can require compatible equipment at both ends.

For example, Windows Central describes the DH2300 as diskless and names WD Red Plus, Seagate IronWolf, and Toshiba N300 as NAS-drive options. That does not establish that every drive suits every model or storage plan; check the NAS maker’s compatibility information and decide how much usable capacity and redundancy you need. Windows Central’s DH2300 coverage discusses the diskless setup. If considering a DXP4800 GT’s 10GbE capability, include any required switch or adapter in the budget rather than assuming that the enclosure alone delivers the faster link.
When a NAS is the better fit—and when the server still makes sense
A NAS may make more sense if
- Your main job is shared storage, backups, or other services the specific NAS supports.
- You want to reduce the power draw of a system that runs continuously, and your own wall measurements show that electricity is a meaningful cost.
- The available bays, network ports, memory, and expansion options match your current storage and application needs.
Keeping or replacing the server may make more sense if
- You need many drive bays: a 12-bay machine offers a capacity and drive-layout option that a four-bay model does not.
- You depend on server applications, expansion, or operating-system flexibility that a NAS model may not provide.
- The up-front price of the NAS, its required drives, and any network upgrades outweigh the electricity savings for your usage and time horizon.
Campanale also describes learning server management and IPMI while using the RD440. That history is a reminder that operational complexity is part of the decision, but it does not establish that every NAS will eliminate maintenance or setup work.
A practical way to decide
- List the jobs your machine does. Separate ordinary file storage and backups from containers, media processing, and services that require specific hardware or software.
- Measure power at the wall. Record the complete system’s draw in representative idle and active conditions, then calculate the cost using your electricity rate and actual operating hours.
- Set the storage requirement. Count the drives and bays you need now, account for planned growth, and compare usable capacity rather than relying only on raw maximum-capacity claims.
- Check the full network path. Match the NAS port to your computer, switch, cabling, and adapters; faster ports help only when the rest of the path supports them.
- Compare total costs and capability. Include enclosure, drives, electricity, required network upgrades, and any server functions you would need to move or retain.
That process produces a more useful answer than comparing processor labels. Campanale’s experience shows why a lower-power NAS can be compelling for one home setup, but the 12-bay server’s storage capacity and broader server role remain relevant trade-offs.
