SSD或固态驱动器^{(Solid State Drive)}并不是一个新术语。固态硬盘^(SSDs)已经上市好几年了，但很少有人知道他们在做什么。从本质上讲，SSD是对旧^(SSDs)HDD（硬盘驱动器^{(Hard Disk Drive)}）的升级，它们提供更快的启动时间、更快的处理速度，但成本要高得多。

与传统硬盘驱动器不同，SSD使用NAND闪存，可以持续使用数年。但是，为现实生活中的表现付出额外的钱真的值得吗？让我们来了解一下。

您需要SSD还是固态驱动器^{(Solid State Drive)}

首先，您可能希望选择SSD代替标准HDD的原因有很多。

• 旅行时笔记本电脑可能会被撞到^{(Laptops might take get bumped around when you travel)}

如果您经常带着笔记本电脑旅行，那么当您随身携带时，您的电脑肯定会在不同的地方撞到。最好拥有一台装有SSD的机器，以便在遇到碰撞时知道您受到坚固驱动器的保护。

• 流动性是关键^{(Mobility is key)}

SSD的另一个好处是，与传统的HDD相比，它更便于携带和移动。SSD最终节省了空间以在笔记本电脑中包含其他硬件，甚至减轻了重量和厚度。SSD^(SSDs)也需要更少的电量，因此您的笔记本电脑电池应该可以使用更长时间。

• 启动时间降低^{(Boot times are lowered)}

最后，启动时间。如果您是Windows PC 拥有者的时间最长，那么您肯定已经感受到了长时间等待系统启动的痛苦。使用SSD，尤其是在启动Windows 10时，将帮助您注意到在桌面上加载所有应用程序所用时间的突然变化。

因此，既然您已经选择了确实需要为您的机器配备 SSD，那么是时候了解一些技术了。^{(So, now that you have chosen that you do indeed want an SSD for your machine, it’s time to get a bit technical.)}

适合您的 SSD 的内存类型

• 单级单元 (SLC)^{(Single-Level Cell (SLC))} – SLC内存实际上是任何SSD上速度更快的内存类型。在读取和处理数据方面，它也是最精确的，这可以更好地延长系统的电池寿命。但最糟糕的是，SLC也是最昂贵的，而带有SLC的^(SLC)SSD^(SSDs)通常用于企业^(Enterprise)版。

• 多级单元 (MLC)^{(Multi-Level Cell (MLC))} – MLC内存在不增加物理尺寸的情况下具有更大的存储量，价格比SLC^(SLCs)低，但反过来，写入和读取速度较慢且精度较低。与SLC^(SLCs)相比，它们还吸收​​更多的能量并且更不耐用。

• 三级单元 (TLC)^{(Triple-Level Cell (TLC))} – TLC是同类产品中最便宜的，因此在消费者领域非常受欢迎。但是，它也具有最低和最不精确的写入和读取速度。由于功耗增加，与其他两种内存变体相比，它的耐用性也低得多。

因此，这是对SSD^(SSDs)是什么以及如何选择合适的 SSD的简要总结。如果您有任何建议，请在下方告诉我们。

Do I really need an SSD or Solid State Drive?

The SSD or Solid State Drive isn’t exactly a new term. SSDs have been on the market for quite a few years now, but not a lot of people know what they do. Essentially, SSDs are an upgrade over the older HDD (Hard Disk Drive), and they offer faster boot times, faster processing speeds but at a substantially higher cost.

Unlike your traditional hard disk drives, an SSD uses NAND flash memory, which can last for years on a stretch. But is it exactly worth the extra bucks for real-life performance? Let’s find out.

Do you need an SSD or Solid State Drive

To start with, there are multiple reasons why you might want to opt for an SSD in place of a standard HDD.

• Laptops might take get bumped around when you travel

If you travel a lot with your laptop, chances are your computer is sure to get bumped off on different places when you carry it around. It is better to have a machine that sports an SSD to know that you are protected with a sturdy drive when you get bumped.

• Mobility is key

Another benefit of an SSD is that it is much more portable and mobile compared to the traditional HDD. The SSD ends up saving space to include other hardware in the laptop, and even reduces weight and thickness. SSDs also require less power, so your laptop battery should last longer.

• Boot times are lowered

And finally, boot time. If you have been a Windows PC owner for the longest time, you surely have felt the pain of waiting for your system to boot up after a long time. Using an SSD, especially for booting up Windows 10 will help you notice the sudden changes in the time taken to load all your apps on the desktop.

So, now that you have chosen that you do indeed want an SSD for your machine, it’s time to get a bit technical.

The right type of memory for your SSD

• Single-Level Cell (SLC) – SLC memory is practically the faster type of memory on any SSD. It is also the most precise when it comes to reading and processing data, which makes it better for your system’s battery life. But the worst part is that SLC is also the most expensive of the lot and the SSDs with SLC are usually used in Enterprise editions.

• Multi-Level Cell (MLC) – MLC memory has a larger amount of storage without an increase in physical size, are available for a lower price than SLCs, but, in turn, have slower and less precise write and read speeds. They also suck in more power and are less durable compared to the SLCs.

• Triple-Level Cell (TLC) – TLC is the cheapest of the lot and thus quite popular in the consumer segment. But, it also has the lowest and least precise write and read speeds. It is also much less durable compared to the other two memory variants due to increased power consumption.

So, this was a brief summary of what SSDs are and how you should choose the right one. Do let us know if you have any suggestions, below.
