So what's going on with the M1 SSDs?Īpple has some world-class SSD engineers. While reads are microseconds quick, writes can take milliseconds - not much better than hard drives.Īnd there's more, like write amplification and read disturbs, that call for more controller acrobatics to mitigate. Writes are WAY slow and take a lot of power. ![]() ![]() what PCs use - NAND flash may handle as few as 500 writes over a cell's lifespan. That voltage steadily wears away the insulation that lines the quantum well. Herding electrons into a quantum well takes power, way more than the 5 volts common in solid state circuits. Electrons, those bad boys, are always trying to sneak out, which is why SSDs aren't forever, unlike, say, M Discs. Flash stores electrons in tiny physical quantum wells. NAND flash is an analog medium, unlike the magnetic bits in hard drives, or the optical pits in DVD media.The new M1 iMac highlights everything that's wrong with Apple M1 MacBook Air: After 3 months use, here's what I wish I'd known Mac Mini review: Most affordable M1 Mac offers great valueĪpple M1: Will storage and memory limits be a problem for pros?
