It's a fair comparison. Both Apple's computers and drives like the WD SN850x are using commodity SSD-grade TLC flash; there's no significant difference in quality, performance, efficiency, or durability in the flash itself. It's possible (maybe even likely) that a Mac with 2TB of built-in storage is using literally the same NAND flash dies that show up in a SN850x.
SSD performance and power efficiency are significantly affected by the choice of controller. Apple's Macs have the controller built-in to the SoC, so it's a sunk cost that doesn't really factor in to upgrade pricing.
- Retric 2y agoI said poor not unfair. They might happen to end up with equal price per flash chip, but either could end up being more expensive it’s just not a good yardstick IMO. Anyway, what you might consider insignificant differences are things companies do consider these worth paying for. You not caring isn’t the same thing as nobody caring. > significantly affected by the choice of controller Aka it is more complicated than just slapping different controller on the same chips and calling it a day.
