我的是 mini， 感觉还好， 平常开好几个 xCode 和模拟器。
我把自动睡眠给关了， 尽量不开 intel 专属软件， 特别是微信。
唯一就是要经常重启。。。 感觉内存还是容易溢出

4T 三星 860pro MLC 的 TBW 才敢标 4800T，你这 256G 的就敢说 2000T，真是什么都敢吹。

参考标准不一样吧，不过 TBW 至少是厂商明确标示的，超出 TBW 就过保。

@egen 我查了下资料 ，确实有可能 。


SLC: Single-level cell NAND flash supports 50,000 to 100,000 write cycles.

MLC: The 2-bit data multi-level cell (MLC) flash generally takes up to 3,000 write cycles. eMLC (enterprise MLC) sustains up to10,000 write cycles, and can reach 35,000 cycles on 3D NAND.

TLC: Triple-level cells (3-bit) NAND flash is low at 300-1000 write cycles, and can achieve 1500-3000 write cycles with 3D NAND.

使用 eMLC 能有 10000 次读写。256G*10000=2560T
