This also makes the assumption that you'd have zero time copying the data once you arrived in London. More realistically, you'd probably make a copy. In this case, you need to also take into account the amount of time copying the files at the other end. Depending on your external drive's interface, this is a non-trivial amount of time.
- reitzensteinm 14y agoWell if we're speaking more realistically, you'd use this for shipping 100tb worth of disks (which would fit in your luggage in both size and weight), and it would blow away just about any internet link you could lay your hands on with a remotely similar budget. That is a great point though. A 4TB drive, hooked up to your internal SATA port, will do about 130 megabytes per second, which is around 9 hours for a full copy. Drive speeds increase linearly with track density, but drive capacity increases quadratically, so this is only going to get worse. Hard drives are the new tape.
- whatusername 14y agoFor a point of reference -- LTO5 pushes data at up to 140 megabytes per second. (But Tape has the same problem -- Capacity increases faster than speed)
- sliverstorm 14y agoThis is why you ship the whole server. No shuffling around data- it's already where you want it, on the server. Just plug it in to the cluster.
- geon 14y agoWouldn't the disk be enough? (Asuming it is the right model.)
- sliverstorm 14y agoYeah, but that assumes you have empty chassis sitting around. Besides, if you're shipping 100TB that's not just one disk.
