通常情况下，离硬件越近，离现实越远。不仅在M1内核及其性能中可以看到这一点，而且在存储方面也是一个很好的规则。
我一拿到第一台M1 Mac电脑，就对其进行了现成的磁盘基准测试，以比较其内部SSD与iMac Pro的速度。其中一些结果表明，近20 GB/s的传输速率高得离谱，这似乎是缓存的结果。换句话说，SSD欺骗了测......

人们经常告诉我他们不了解性能工具输出，因为它们可以＆＃39; t告诉39; s＆＃34;好＆＃34;或＆＃34;坏。＆＃34;它可能很难，因为性能是主观的。什么＆＃39;对于一个用户而言，对另一个用户可能不好。还有我可以在哪里＆＃39; t告诉他们：工具只提供进一步分析的线索。

如果您可以购买具有无限存储容量的1 TB外部SSD，您是否准备为此付出代价呢？感谢Big Sur中的Disk Utility，我现在可以揭示如何在单个1 TB磁盘上获得数TB的APFS容器。可悲的是，它们只是磁盘工具想象力的虚构，是一个错误，而不是真实的。

我已经建立了最不方便的音乐播放方式！这是低保真的可怕和赛博朋克的垃圾。
正如我昨天所讨论的，一张软盘可以容纳半小时的演讲。世界上最好的乐队是披头士乐队，他们最短的专辑是“艰难的一天的夜晚”--时长30分45秒。甲壳虫乐队的音频被设计为在拙劣的AM收音机上以单声道播放，因此非常适合使用最新的音频编解码器进行压缩。
好的......

Unix始于1970年。它所做的许多事情，它不得不在飞行中发明。磁盘处理就是其中之一。我们今天完全认为理所当然的事情，曾经是一个积极创新的领域。这篇博客将探索Unix的早期：那时我们将静态分区编译到驱动程序中。
那个时代的典型驱动器：很大，而且很难管理(从外观上看，RL01或RL02可以容纳5MB或10MB的存储空间......
