NAS Network Speed Calculator: Estimate Throughput and Transfer Time
Ethernet labels describe link capacity, not guaranteed file-copy speed. Protocol overhead, storage media, client count, Wi-Fi conditions and small-file workloads all reduce throughput. This calculator estimates a practical range by combining the network and storage limits.
Estimate NAS throughput and transfer time
Select the network and storage limits, then calculate. No result is prefilled.

The slowest component sets the ceiling
A 10GbE link connected to one hard drive will usually be limited by the drive. A fast NVMe NAS connected through 1GbE will be limited by the network.
Small files transfer more slowly
Thousands of small files create more filesystem and protocol work than one large sequential file. The calculator is closest to large-file transfers and provides a caution for mixed or small-file workloads.
Multiple clients share resources
Several clients can share the network link, storage array and processor. The calculator divides available storage throughput across active heavy users to produce a conservative estimate.
Frequently asked questions
Why is 1GbE not 125MB/s in practice?
One gigabit equals 125 megabytes per second before Ethernet, TCP, filesystem and application overhead. Real large-file transfers are normally lower.
Can one hard drive saturate 2.5GbE?
Some fast sequential workloads can approach it, but many single drives and mixed workloads remain below the practical 2.5GbE ceiling.
Why is Wi-Fi less predictable?
Wireless throughput changes with distance, interference, channel use, client antennas and airtime shared with other devices.
