Oct 2020, StorONE announced a 1PB All-Flash array for $499k.

No doubt about that, when you have tens of thousands of drive you end up replacing some of them all the time, but not 15% of them every year…

With Optane and all, right? The kind of things that's a massive overkill if your workload allows you to use Glacier…

In that list, the only offers that are close to this pricing (but still almost 20% cheaper) also includes several years of support (which you probably don't want if you're Canva's scale).
mind you the price of flash storage has dropped significantly since 2020.
Hard disks are still being used, but having all flash systems is not uncommon.

For one PB? Gold plated HDDs and cases I guess…
> Assume 15% annual system maintenance over five years
Do not run your hard drive cluster on the same floor as vibration-inducing machines, folks. /s
According to Backblaze, even a 8 year-old hard drive is still twice more reliable than this, and 15% failure rate is what to expect over 6 years of consecutive use!
> Assume the space needed to store 1PB is between 25%-50% of a standard rack (42U)
You can fit almost 10PB in a rack though, so that's another figure that they've inflated.
> Assume personnel costs to manage a 1PB system are 0.5 IT/storage admin FTE
This one is probably true (and it's even an underestimation) if you have only 1PB of data, but it's not going to scale linearly: you're never going to need 130 FTE for 260PB.
Overall, if a supplier (who's going to use the same kind of off-the-shelf tech as you would) claims that his price is 4 times cheaper that what it would cost you to run it by yourself, he's probably just lying to sell you stuff, just saying…
