mac 固态硬盘 格式化

If you are new to working with computer hardware, then you may find yourself wondering about ‘wear and tear’ on your HDD or SSD. Today’s SuperUser Q&A post takes a look at the topic to help a curious reader understand more about HDDs and SSDs.

如果您不熟悉计算机硬件，则可能会对HDD或SSD的“磨损”感到好奇。 今天的SuperUser Q＆A帖子介绍了该主题，以帮助好奇的读者更多地了解HDD和SSD。

问题 (The Question)

SuperUser reader Suvarna Amar wants to know if there is a limit to the number of times that a hard-disk drive can be formatted:

超级用户阅读器Suvarna Amar想知道硬盘格式化的次数是否有限制：

Is there a limit to the number of times that I can format a hard-disk drive? I looked for this information on Wikipedia, but was unable to find an answer.

我可以格式化硬盘驱动器的次数有限制吗？ 我在Wikipedia上查找了此信息 ，但找不到答案。

Is there a limit to the number of times an individual can format a hard-disk drive?

个人格式化硬盘的次数是否有限制？

答案 (The Answer)

SuperUser contributor allquixotic has the answer for us:

超级用户贡献者allquixotic为我们提供了答案：

With the exception of CDs, DVDs and Blu-Ray discs (collectively called “optical media”), formatting is not a special action and is fundamentally the same as any other disk operation. Formatting a storage device (whether it is a hard-disk drive (HDD), solid state drive (SSD), or flash drive) just involves regular old reads and writes to the disk.

除CD，DVD和Blu-Ray光盘(统称为“光学介质”)外，格式化不是一项特殊的操作，基本上与其他任何磁盘操作相同。 格式化存储设备(无论是硬盘驱动器(HDD)，固态驱动器(SSD)还是闪存驱动器)仅涉及对磁盘的常规旧读取和写入。

The only matters of concern are:

唯一需要关注的事项是：

• Are you performing a quick format or a full format? A quick format just overwrites the core file system data structures with a new file system and usually only involves a few megabytes of writes (compared to many gigabytes or terabytes of total disk space). A full format only writes a small amount of data, but reads from every part of the disk to make sure the disk is okay.您要执行快速格式化还是完整格式化？ 快速格式只是用新文件系统覆盖核心文件系统的数据结构，通常只涉及几兆字节的写入(相比之下，总磁盘空间为数GB或TB级)。 完整格式只会写入少量数据，但会从磁盘的每个部分进行读取以确保磁盘可以正常运行。
• Usually after you format a disk (if it is your primary storage), you are going to install an operating system on it. This usually causes 2 – 25 GB of disk writes at first, plus another several gigabytes to install programs and updates.通常，在格式化磁盘(如果它是您的主存储)之后，您将在其上安装操作系统。 通常，这首先会导致2到25 GB的磁盘写入，再加上几GB的磁盘来安装程序和更新。

All this writing of new data (which will vary in quantity depending on what type of format you performed and what you are going to do after you format it) can cause wear on SSDs and, to a lesser degree, the mechanical parts of HDDs. The amount of wear is proportional to the amount of data that is being read and/or written, with SSDs largely unaffected by reads, but HDDs being affected roughly the same by reads and writes.

所有这些新数据的写入(数量会有所不同，具体取决于执行的格式类型以及格式化后要执行的操作)会导致SSD磨损，并在较小程度上导致HDD的机械部件磨损。 磨损量与正在读取和/或写入的数据量成正比，其中SSD在很大程度上不受读取的影响，但HDD受到读取和写入的影响大致相同。

I am not going to delve into the topic of disk endurance and how certain quantities and frequencies of reads and writes affect the endurance (wear level) of different types of disks. This is a very complex topic that is completely independent from the subject of disk formatting.

我不会深入探讨磁盘的耐用性，以及某些读写次数和频率如何影响不同类型的磁盘的耐用性(磨损程度)的主题。 这是一个非常复杂的主题，与磁盘格式化主题完全无关。

Just know that the operation of reinstalling Windows on a hard-disk drive is basically doing the same thing to your disk as copying several gigabytes of movies or pictures or music. Just the act of using a computer involves very frequent disk reads and writes.

只需知道在硬盘驱动器上重新安装Windows的操作基本上与复制几GB的电影，图片或音乐在磁盘上的作用相同。 只是使用计算机的行为涉及非常频繁的磁盘读取和写入。

The only difference is that formatting a disk and then using it often incurs a fairly large amount of reads and writes compared to what a typical user might do in a day.

唯一的区别是，格式化磁盘然后再使用它通常会引起与普通用户一天中所做的相当多的读写操作。

Analogy: If you normally drive 8 km to work every day in your car and then take a holiday trip of 200 km, this is fundamentally the same action, you are just driving further. Formatting causes more wear on your disk, just like driving further causes more wear on your car.

打个比方：如果您通常每天开车开车行驶8公里，然后进行200公里的假日旅行，那么这基本上是相同的操作，您只是在继续行驶。 格式化会导致磁盘上更多的磨损，就像进一步驱动会导致汽车上的更多磨损一样。

If you want to know how reading and writing data impacts the endurance of your particular type of disk, you can either ask a new question, search for existing questions, or use Google to find this information.

如果您想知道读写数据如何影响特定类型磁盘的耐用性，则可以提出一个新问题，搜索现有问题，或者使用Google查找此信息。
