> You should expect 4 MB/s of throughput per TB of data stored as Nearline Storage.

But still, you are correct in that it will take about 1TB / 4MB/s = 2.9d to retrieve all your data.

If you need the ability to do a restore faster than this, then you need to pay more for storage, is all. For many of us, waiting 3d to recover from a catastrophic failure isn't a big deal.
