The shore is cool, but dry. Back into the comforting murk.

  • 3.5" hard drives have a physical volume of about 0.0107 cubic feet. A Chevy Express has a cargo volume of 239.7 cubic feet. Assuming that only 200 cubic feet can be effectively used, roughly 18,000 hard drives can be loaded into the van. If each hard drive is a 22TB Western Digital (largest mass available to consumers), that’s 396,000TB of data. Let’s assume a travel distance of 2 hours in the van, with an extra 4 hours on each end for unloading/loading. That’s 396000TB per hour/6600TB per minute/110TB per second. Most wireless connections are measured in mega/gigabits (not bytes) per second, so that’s 880Tb per second. This is far faster than any wireless connection available, even with much longer travel and unloading times. We can therefore conclude that a van full of hard drives has very good bandwidth.
