Question: how long does it take to transfer 1gb over gigabit ethernet?
Answer: In a 1 Gbps connection, 1 Gigabit will take 1 second. Since there are 8 bits in a byte, 1 Gigabyte will take 8 times longer. So your 1 GB file will take 8 seconds in ideal conditions. However, hard disk speeds are usually much slower, so your file transfer might take three times longer to complete.
