When reviewing NodeLivo's Silicon Valley CN2 bare metal cloud offerings, you will see two server configurations that appear very similar: both feature dual E5-2683v4 CPUs, 64GB RAM, and a 1TB HDD, with the main distinction lying in the network setup. One comes with 30Mbps unmetered bandwidth, while the other offers 1Gbps with 10TB/month.
At first glance, seeing 1Gbps might lead you to choose it immediately for its higher bandwidth limit. On the other hand, seeing an unmetered plan might make you worry that 10TB per month won't be enough.
Both aspects are worth considering, but once you do the math, making the right choice becomes much clearer.
Bandwidth and Data Transfer: Understand the Difference
30Mbps and 1Gbps refer to port bandwidth, whereas 10TB represents your monthly data transfer allowance.
Port bandwidth determines how much data can be transmitted in a short window of time, while data transfer determines the total accumulated volume you can use over a month.
Another detail people often confuse is units: the lowercase "b" in Mbps stands for bits, while the uppercase "B" in MB/s (commonly used in download clients) stands for Bytes. Converted at a rate of 8 bits = 1 Byte, 30Mbps translates to a theoretical transfer rate of 3.75MB/s, whereas 1Gbps equals 125MB/s.
These values represent theoretical maximums based on unit conversion. Actual download speeds will depend on line quality, remote network conditions, disk performance, and protocol overhead. You should never assume every visitor will achieve full port capacity.
How Much Data Can 30Mbps Unmetered Actually Transfer in a Month?
Here is an easily overlooked detail.
Assuming a 30Mbps connection is fully saturated continuously for 30 days straight, measuring unidirectional transfer without factoring in protocol overhead and using decimal calculations:
30,000,000 ÷ 8 × 60 × 60 × 24 × 30 ≈ 9.72TB
In other words, even if a 30Mbps port runs non-stop for a full month, it theoretically tops out near this amount. In reality, actual business traffic rarely runs at full saturation 24 hours a day.
Therefore, you shouldn't assume "unmetered" automatically means you can transfer more data than a 10TB plan. "Unmetered" simply means there is no fixed monthly transfer quota specified, but speed remains capped by bandwidth limits, and continuous high usage must still adhere to Terms of Service.
This is why doing the calculation beforehand is far more useful than merely comparing specifications by name.
For Websites, Peak Traffic Matters More Than Monthly Average
Consider a website with modest daily traffic and compressed images whose overall network usage remains consistently low. For such workloads, checking bandwidth monitoring logs will easily confirm whether 30Mbps is sufficient.
However, if your website hosts promotional events or experiences frequent concurrent file downloads, the situation changes. You might consume less than 10TB in a month overall, yet require significantly higher bandwidth during specific peak windows.
In this scenario, a 1Gbps port provides genuine value by offering a much higher ceiling for burst data transfer. How much speed you actually achieve in practice still requires testing.
Conversely, if you plan to transfer large files continuously over long periods, do not architect your operations around running at 1Gbps full speed all day. 10TB is a monthly quota, and sustained heavy traffic will exhaust it quickly. Make sure to clarify how overages are handled before deploying, rather than waiting until your service is live.
Even with CN2, Testing It Yourself Is Recommended
While both offerings are labeled with CN2 routing, the data center is located in Silicon Valley. The actual end-user experience will depend heavily on where your users are coming from and which network providers they use.
If your primary user base is located in Mainland China, test performance across China Telecom, China Unicom, and China Mobile individually, particularly during busy peak hours. Beyond running speed tests, open your website and log into your management dashboard to test real application workflows.
Bandwidth and latency are distinct metrics. Having a larger port capacity does not automatically mean shorter response times for every request.
Additionally, both server configurations feature 1TB HDD storage. If your workload demands high disk I/O performance, evaluate storage specifications alongside network capabilities rather than focusing exclusively on network bandwidth.
How Would I Choose Between These Two Options?
If your current workload remains well below 30Mbps even during peak traffic hours, there is no need to judge server quality solely by port speed numbers. Focus instead on routing quality, real-world latency, and service terms.
If your daily traffic volume is modest but requires burst capacity during occasional peak times, and you've verified that 10TB monthly is sufficient, I would lean toward the 1Gbps option.
If your expected monthly transfer is close to or exceeds 10TB, you should look for a higher bandwidth quota or inquire whether traffic add-ons are available. Opting for 30Mbps unmetered means accepting its capped maximum speed ceiling.
Before placing an order, clarify a few essential rules: Is the 10TB quota outbound-only or combined in/out traffic? When does monthly bandwidth reset? In case of an overage, is traffic throttled, suspended, or billed at overage rates? Are there shared or fair-use sustained limits on the advertised bandwidth?
Once these policies are clear, comparing pricing will give you a clear answer on which option best suits your business requirements.
