手順8
Back to the business of taking things apart: next up are these twin "SSDs." Under a couple stickers we find some Torx screws. Off they go! Each blade is designated Apple EMC 3197, model 656-0061A.
  • Back to the business of taking things apart: next up are these twin "SSDs."

  • Under a couple stickers we find some Torx screws. Off they go!

  • Each blade is designated Apple EMC 3197, model 656-0061A.

  • Popping the shields off, we encounter some chips:

  • SanDisk SDRQF8DC8-128G (four per card, two top and two bottom, for a total of 512 GB × 2 = 1024 GB)

  • Apple 338S00285 power management IC (likely)

  • Unlike a standard SSD, which has the controller logic onboard, these raw flash modules only have an interface buffer—the PCIe/NVMe controller lies elsewhere. More on that in a bit.

回到我们的工作上:接下来我们该拆出这个双固态硬盘了

在两张螺丝保护贴纸下,我们找到了星型螺丝,拆掉他们!

每片闪存均采用 Apple EMC 3197,型号 656-0061A。

屏蔽罩去掉后,可以看到如下芯片:

闪迪(SanDisk)SDRQF8DC8-128G (每张SSD带有4个相同芯片,两个位于上部,两个位于下部,提供总共512 GB X 2 = 1024 GB的存储空间)

Apple 338S00285

与板载控制器的标准SSD不同,这些原始闪存模块只有一个接口缓冲区,PCIe / NVMe控制器位于其他位置。 关于这一点,会在之后详细叙述。
