从数码相机到智能手机、平板电脑、音乐播放器、笔记本电脑甚至您的Nintendo Switch，现代设备都需要(Nintendo Switch require)存储空间。
如果您设备的集成存储(storage isn)不足以(t adequate)存储照片、视频、游戏、音乐等所有媒体文件，它可能有一个microSD 插槽(microSD slot)，可让您根据自己的喜好扩展存储。出于这个原因，制造商现在生产具有更大存储容量(storage capacity)和更快数据传输速度的 microSD 卡。
如果您正在市场上为您的设备购买最好的microSD 卡(microSD card)，您会很快发现它们并非生而平等。有不同的尺寸、容量、速度等级，甚至品牌需要考虑。
在本指南中，我们将分享您在为您的设备选择正确的(share everything)microSD 卡(microSD card)时需要记住的一切、要避免的一些常见错误以及最佳microSD 卡(microSD card)选项。
购买 MicroSD 卡时要寻找的功能(Features To Look For When Buying a MicroSD Card)
不同的 microSD(Different microSD)卡具有不同的存储量，但microSD 卡(microSD card)的大小将取决于您需要多少以及根据您的设备需要它的用途。与大容量卡相比，小容量(Smaller capacity)卡往往会很快填满，但您需要在用完之前检查设备可以支持的最大尺寸并购买容量更大的卡。(check the maximum size your device can support)
也就是说，为了更好的组织、防止损坏和卡的安全性，你最好投资一些最好的中等大小的 microSD 卡，而不是一两张大容量的卡。
速度(Speed)
除了存储空间之外，您还需要一张能够快速读取和写入数据的microSD 卡(microSD card)，尤其是在您观看电影、复制数据、加载游戏关卡或捕捉视频时。检查卡的连续速度，它告诉您在拍摄高分辨率视频和照片(high-resolution video and photos)或将媒体文件复制到卡时可以多快地从卡中读取大量数据。
该卡还需要在随机位置快速读取和写入数据，这就是随机速度(random speed)很重要的原因，尤其是当您将它们用于运行操作系统、应用程序/程序或加载游戏时。
Speed Rating/Class
在选择最佳 microSD 卡时，卡的速度评级系统(speed rating system)也很重要，因为它关系到其传输速度性能(transfer speed performance)。除非您的设备规定较低的速度等级(speed class)要求（以MB/s为单位），例如2 类(class 2)、4 类或 6 类，否则请找到额定至少为 10 类(Class 10)、U1 或 U3(U1 or U3)的卡，因为它们可以写入至少 10 MB/s或更高的顺序数据。
有速度更快的 microSD 卡，额定为V60 或 V90(V60 or V90)（视频速度等级），但这些卡价格更高，需要罕见的更高UHS总线速度标准，以(UHS)更快的速率(faster rate)双向传输数据。
UHS 总线速度(UHS Bus Speed)
超高速 ( UHS )总线速度(Bus Speed)是衡量数据如何在microSD 卡(microSD card)上的引脚和设备连接器之间传输的指标。共有三个版本：UHS I，数据传输速度高达 104 MB/s，而UHS II 和 UHS III 数据传输(UHS II and UHS III move data)速度分别高达 312 MB/s和 624 MB/s。
一些制造商在他们的卡上列出了速度等级和 UHS 总线速度(speed rating and UHS bus speeds)，这就是我们将这两个类别分开的原因，这样您就知道在为您的情况选择最佳microSD 卡(microSD card)时要寻找什么。
SDHC 和 SDXC(SDHC And SDXC)
MicroSD卡可以是安全数字高容量(Secure Digital High Capacity)( SDHC ) 或安全数字扩展容量(Digital Extended Capacity)( SDXC )，它们的存储容量(storage capacity)不同。SDHC是提供 4-32 GB 的低容量 microSD 卡，而SDXC提供从 64 GB 到 2 TB 的更高容量。许多设备，尤其是手机，都可以使用SDXC microSD卡，但移动控制台等设备只能接受SDHC microSD卡。
其他要考虑的因素包括卡的保修，因为制造商提供较短的保修，而其他的则提供 10 年有限或终身有限保修。另外，请检查您正在考虑的 microSD 卡是否来自知名品牌或卖家(brand or seller)，如Sandisk、Samsung、Kingston、Lexar、Transcend等，以避免购买假冒卡。有些卡还声称防水、防震、防 X 射线，并且可以在极端温度下工作。
人们在购买 MicroSD 卡时犯的错误(Mistakes People Make When Buying MicroSD Cards)
了解购买 microSD 卡时需要注意的事项有助于避免一些常见错误，这些错误可能会导致您花钱。您也可能最终在一张根本不起作用的卡上表现不佳。
人们在购买 microSD 卡时最常犯的错误是：
1. 在大型市场网站上从第三方卖家处购买(1. Buying from a third-party seller on big marketplace sites)。这些卖家可能没有信誉，即使他们是通过大型零售商销售的。MicroSD卡经常是伪造的。此类仿冒品速度较慢，没有相同的广告容量，并且没有保修。如果可能，直接从信誉良好的卖家那里购买(Buy)，例如品牌制造商。(brand manufacturer)如果在Amazon上购买，请查找“ Ships from and sold by Amazon .com”并选择原包装。
始终选择大品牌的 microSD(brand microSD)卡，因为它们更可靠，并提供更好的性能、保修、防水、防震、极端温度和 X 射线(temperature and x-rays)保护。有些还提供对图像恢复软件(image recovery software)的访问作为标准功能。
2.不检查设备兼容性(2. Not checking device compatibility)。MicroSD卡并非都是平等的。有些兼容并适用于特定设备，而有些则不兼容。设备兼容性(Device compatibility)将确保您获得适合您设备的卡。例如，有些是为Raspberry设计的，而另一些则适用于基于 Android 的小工具、Nintendo Switch等。购买前检查(Check)microSD卡插槽(card slot)，如果您的设备有全尺寸 SD卡插槽(card slot)，则购买带适配器的 micro SD 卡(SD card)。
3.为您的任务选择错误的卡片(3. Choosing the wrong card for your task)。MicroSD卡的设计不同，因此您需要选择一款与其预期用途相匹配的卡。检查capacity and speed rating/class，以便根据用例(use case)获得具有足够存储空间和快速速度的设备。例如，使用数码相机拍摄视频或在手机上存储(camera or storing) 应用程序和媒体文件(apps and media files)需要(phone require)不同的 microSD 卡。

3 Best MicroSD Cards To Buy in 2020
Modern devices from digital cameras, to ѕmartphones, tablets, music players, laptops and even your Nintendo Switch require storage.
If your device’s integrated storage isn’t adequate to store all your media files like your photos, videos, games, music and more, it probably has a microSD slot to allow you to expand storage to your liking. For this reason, manufacturers now produce microSD cards with more storage capacity and faster data transfer speeds.
If you’re in the market for the best microSD card to buy for your device, you’ll quickly discover that they’re not all created equal. There are different sizes, capacities, speed classes, and even brands to consider.
In this guide, we’ll share everything you need to keep in mind when picking out the right microSD card for your device, some common mistakes to avoid, and the best microSD card options.
Features To Look For When Buying a MicroSD Card
Different microSD cards have different amounts of storage, but the size of the microSD card will depend on how much you need and what you need it for based on your device. Smaller capacity cards tend to fill up quickly compared to larger capacity cards, but you need to check the maximum size your device can support before you run out and buy one with a higher capacity.
That said, you’re better off investing in a handful of the best moderately sized microSD cards instead of one or two high-capacity cards for better organization, protection from damage, and security of the cards.
Speed
Besides storage, you want a microSD card that’ll read and write data fast, especially if you’re watching movies, copying data, loading game levels, or capturing video. Check for the sequential speed of the card, which tells you how fast large volumes of data can be read from the card if you’re shooting high-resolution video and photos, or copying media files to it.
The card also needs to be fast at reading and writing data in random locations, which is why the random speed matters, especially if you’re using them for running operating systems, apps/programs, or loading games.
Speed Rating/Class
The card’s speed rating system is also important to consider when choosing the best microSD cards as it relates to its transfer speed performance. Unless your device states lower speed class requirements (measured in MB/s) such as class 2, 4 or 6, find a card that’s rated at least Class 10, U1 or U3 as these can write at least 10MB/s and higher of sequential data.
There are faster microSD cards rated V60 or V90 (video speed classes), but these are pricier and require a rare, higher UHS bus speed standard that can shuttle data in both directions at a faster rate.
UHS Bus Speed
Ultra-high speed (UHS) Bus Speed is the measure of how data is transferred between the pins on the microSD card and your device’s connector. There are three versions: UHS I, which moves data up to 104 MB/s, while UHS II and UHS III move data up to 312 MB/s and 624 MB/s respectively.
Some manufacturers list the speed rating and UHS bus speeds on their cards, which is why we’ve separated the two categories so you know what to look for when choosing the best microSD card for your case.
SDHC And SDXC
MicroSD cards can either be Secure Digital High Capacity (SDHC) or Secure Digital Extended Capacity (SDXC), which differ in storage capacity. SDHC are low-capacity microSD cards that offer 4-32 GB, while SDXC offer higher capacities from 64GB up to 2TB. Many devices, especially phones, work with SDXC microSD cards, but fewer devices like mobile consoles can accept SDHC microSD cards only.
Other factors to consider include the card’s warranty, as manufacturers offer a shorter warranty, while others offer 10-year limited or lifetime limited warranties. Plus, check that the microSD card you’re considering is from a reputable brand or seller like Sandisk, Samsung, Kingston, Lexar, Transcend and so on, to avoid buying counterfeit cards. Some cards also claim to be water-proof, shock-proof, x-ray proof, and work in extreme temperatures.
Mistakes People Make When Buying MicroSD Cards
Knowing what to look for when buying a microSD card helps you avoid some common mistakes, which could cost you money. You may also end up with poor performance on a card that doesn’t work at all.
The most common mistakes people make when buying microSD cards are:
1. Buying from a third-party seller on big marketplace sites. These sellers may not be reputable, even if they’re selling through a major retailer. MicroSD cards are often faked. Such counterfeits are slower, don’t have the same advertised capacity, and aren’t warrantied. Buy directly from a reputable seller, such as a brand manufacturer if possible. If buying on Amazon, look for “Ships from and sold by Amazon.com” and select the original packaging.
Always go for big brand microSD cards as they’re more reliable, and offer better performance, warranty, protection against water, shock, extreme temperature and x-rays. Some also offer access to image recovery software as a standard feature.
2. Not checking device compatibility. MicroSD cards aren’t all created equal; there are some that are compatible and suitable for particular devices, while others aren’t. Device compatibility will ensure you get the card that’s suitable and will work with your device. For example, some are designed for Raspberry while others are suited for Android-based gadgets, Nintendo Switch, and so on. Check for a microSD card slot before you buy, or buy a microSD card with an adapter if your device has a full-size SD card slot.
3. Choosing the wrong card for your task. MicroSD cards are designed differently so you need to pick one that matches its intended use. Check the capacity and speed rating/class so that you get one with adequate storage and fast speeds depending on the use case. For example, shooting videos using a digital camera or storing apps and media files on a phone require different microSD cards.
