The article says:
> the problem lies in hardware, not firmware, which could explain the lack of corrective firmware updates for those models and SanDisk's continued silence about the source of the issues.
But I'd guess a firmware update that slowed down the erase process could let it cool down. But the performance hit.
Are they not using charge pumps and these are some of the first SSDs upgraded to on-board inductored boost convertors?
These messes could be solved if system power supplies had a 20V rail instead of requiring tiny devices to make it. Maybe an integrated manufacturer (hi apple) will spec out proprietary SSDs like this one day.
Charge pumps are cheap and small, but not as efficient (ie: HEAT!):
> By using the boost converter with the optimized inductor, the energy during write-operation of the proposed 1.8-V 3D-SSD is decreased by 68% compared with the conventional 3.3-V 3D-SSD with the charge pump.

2023 paper:
> One of the main causes is the on-die charge pump circuit, which has a low conversion efficiency and induces high heat generation.
> Using the in package boost converter, we show that the power consumption can be reduced by up to 39% while the temperature rise can be reduced by 50%.

Maybe an integrated manufacturer (hi apple) will spec out proprietary SSDs like this one day. Then you'll get people (like me) who will deride Apple for requiring a proprietary component where COTS components are available, calling it an anti-consumer move.
- Scoundreller 3y agome too, but we're talking about a few extra minutes of battery life here. That's catnip to cat people.
- jona-f 3y agoOh, if it were also smaller and lighter, we'd be in heaven. If it weren't for the proprietary devil lurking in the corner, showing us a fake heaven while having us in chains, sucking the life of our dreams.
