How long does 500gb take to transfer

For example, it is not uncommon for there to be second of overhead per file being copied target service needs to catalog this file, index it, verify it, etc. If you are trying to move , files, this would be , — 1,, seconds, or up to 11 days of overhead alone! These rules of thumb are important because these are what you use in a design meeting before the idea turns into a project.

You can save days of work by knowing rough numbers in advance. Not that these calculations are for file transfers which is easier to define. Trying calculate 20 GB of interactive traffic is much more difficult because the underlying condition is indeterminate. What does the result tell me?

How long would it take to transfer 1TB of data from an external drive to an internal drive over USB 2. USB 2. The same article says that typical real-world throughput is "about two thirds of the maximum theoretical bulk data transfer rate of There is a lot of false information in these answers about "theoretical" performance from people who have evidently never benchmarked USB2 HD transfer rates.

I have benchmarked many different USB2 transfers between 2. I have seen about x faster performance with ESata vs. I just completed 2 of these transfers and I'm surprised at the slow USB 2.

I copied 1 TB terabyte of video files and it took about 16 hours. Avg speed was in the 30's. The 2nd about a week later to a different external HD was 18 hours. And I was annoyed at the 1st transfer :. Depending on the file transferring rate, you can easily benchmark this copying a file of Mb and try to extrapolate that to 1 Tb. Given that a terabyte has 1,, megabytes, you just do the math. Nevermind the same constraints for the source drives read transfer rate. As a real-world example, I just transferred 1.

For average transfers mixed file size , on average harddrives rpm consumer models , USB2 is not significantly slower then IDE or SATA - the speed difference you will encounter will be based almost entirely on overhead - more small files will result in slower transfer speeds.

To get a speed measurement you will need to test using a real sample of the data you will be moving. Divide it by 8 to get bytes.
