What speed do you need to move 10 TB in 24 hours? 925.93 Mbps
By TechCompare · Updated · How we check
The raw minimum is 925.93 Mbps. Gigabit Ethernet just meets a 10 TB in 24 hours deadline, while 2.5 GbE gives much more practical headroom.
A 10 TB migration completed within 24 hours needs 925.93 Mbps at the raw link layer. Gigabit Ethernet technically clears that threshold, but only by about 8%. The deadline is possible on paper and tight in practice.
How this is calculated
The calculation divides 80 trillion bits by 86,400 seconds. It returns 925.93 Mbps, so a 1 Gbps link has only a narrow theoretical margin. Any pause, retransmission, encryption cost, or storage dip consumes that margin. If the window is hard, 2.5 GbE is a more comfortable choice even though the minimum listed match is Gigabit Ethernet.
Verdict
Target 2.5 GbE or faster if the migration has to finish reliably rather than merely fit an ideal calculation. Gigabit Ethernet is the smallest named interface that meets the equation, with a peak time of 22 hours 13 minutes for 10 TB. That leaves about 1 hour 47 minutes for every source, destination, protocol, and scheduling loss.
