这几天，老狐的电脑硬盘空间告急，看了下主板上的一条 M.2 固态硬盘的插槽还空着，于是就想着给自己的电脑加个大容量的固态硬盘。 当时的想法是 2T 起步，价格给力的话直接搞个 4T 的也不是不行。毕竟上次买固态也是两年多以前了，当时买的是 2T 的，用到现在，空间也所剩无几 了。 由于当时买的这个固态用的挺好的，这两年也没出啥幺蛾子，就想着买回同款，为此还专门去京东把两年前的购买链接翻出来。 结果一点开链接，天塌了！当年我 478 元买的 2T 固态硬盘，如今却要 1199 元！ 这是怎么个事儿？固态硬盘啥时候涨成这样了？ 本来以为苹果的存储容量已经够贵了，就拿 iPhone17 来说，256GB 的起步价是 5999 元，而 512G 的就要 7999 元，换句话说在苹果这里 256G 的存储容量 就值 2000 元！ 至于说 Mac 上的运行内存更是如此，8G 就值 1500 元，16G 更是要 3000 大洋！这已经很离谱了，但是，没想到如今却还有高手，2TB 的固态硬盘硬生生 从 478 元涨到了 1199 元！ 以前大家都调侃：苹果的内存和存储是金子做的。 苹果的存储，相对于以往的固态硬盘和内存而言 ...
