Okay, so that 122TB drive costs about $330/TB. I haven't bought a hard drive or an SSD in at least a decade (I get stuff for free, basically) but…that seems a bit high, right? Seems like well-rated consumer-level SSDs cost around $250 for 1TB right now. What accounts for the premium price/TB of these extremely high capacity enterprise-targeted drives?

What accounts for the premium price/TB of these extremely high capacity enterprise-targeted drives? The word "enterprise".

I fondly remember when i could buy a well-rated consumer-level SSD for a lot less per TB...

  I paid $300 each for my last two SSDs, 4 TB Samsung 990 Pros. They’re currently selling for $942.72 on Amazon.

The price graphs of these are wild, wow. https://camelcamelcamel.com/product/B0CHGT1KFJ https://camelcamelcamel.com/product/B0CHGT1KFJ Looks like prices for NAND spiked at the end of last year, a couple of months behind DRAM. Happy not to be building or buying any new computers these days.

> What accounts for the premium price/TB of these extremely high capacity enterprise-targeted drives? Spare capacity, mostly. That’s why they have higher endurance. If you want to double the endurance of a given drive, tell the controller to allocate twice as many spare blocks and report less capacity than you would otherwise. In this case, you are also paying a premium for the PCIe attachment instead of SAS, and a lot for price elasticity. You see, with drives like these you slash space and energy consumption in relation to HDDs by a large number, and that allows you to pay a premium for the device, because, at the end of its lifetime, it’ll have more than covered the cost difference in saved space and energy.

Density, power efficiency, write endurance, sustained write speeds under continuous load, power-loss protection.
