Something about this story doesn't seem to add up. An SSD's firmware presents the raw flash to the OS as a block device. The filesystem is at a higher level of abstraction, above that block device. If the device is handling data that doesn't fit by wrapping back around to the beginning of the file, how is it figuring out where that file begins when all it sees is a bunch AHCI requests?

- dfranke 16y agoThanks, that makes more sense.
