Does the $26/TB for hard drives include the cost of the JBOD chassis you'll need to to have them all online at once, in order to get those speeds?

- Dylan16807 6y agoNo, but I didn't include the cost of the tape robot either. I'm seeing prices like $10k for a 6U/80 tape robot, and $10k per 80 drives is more than enough for a very fast JBOD chassis. You could more than double the budget of a Backblaze pod, and upgrading to an EPYC and 100 gigabit ethernet would only take about a thousand dollars. Also even in some ridiculous circumstance where your tape robots were free and you have to pay $7.2k per JBOD chassis, that still only bumps the cost to $36/TB and the overall analysis doesn't change much. $26/TB was an overestimate anyway. Especially when you can get 5400RPM drives for $18/TB, and it only hurts your speed by about 20%.
