存储卡存在于各种设备中：专业数码单反(DSLR)相机、监控摄像头、行车记录仪、智能手机、平板电脑和笔记本电脑。我们甚至将它们用于Nintendo Switch控制台。某些设备（如数码相机）需要存储卡(memory card)作为主要存储设备。其他人（如平板电脑和智能手机）需要它们来增加存储空间(storage space)。存储卡有多种尺寸、格式、速度和存储容量。理解一切可能会让人望而生畏。为了帮助您，我们创建了本指南，其中涵盖了购买下一张存储卡(memory card)时要考虑的最重要标准：
注意：(NOTE:)本指南涵盖了在选择适合您需求的最佳存储卡时涉及的基本原则，适用于(memory card)金士顿(Kingston)的产品组合(portfolio)。
一、存储卡(memory card)的种类和物理尺寸
首先(First)，明确你需要什么类型的存储卡(memory card)。这取决于您计划在其中使用存储卡(memory card)的设备。您可能拥有仅适用于CompactFlash卡的DSLR 相机，例如(DSLR camera)Kingston的Canvas Focus CompactFlash。
您可能需要一张可用于标准SD 格式和 microSD的多功能(SD format and microSD)SD 卡(SD card)，例如Kingston's Canvas Go! Plus microSD加上 microSD。这种卡可以插入多种设备，如数码相机、平板电脑和智能手机。
存储卡有不同的类型和尺寸：Compact Flash、SD、miniSD、microSD 等。要熟悉并了解它们之间的区别，请阅读：有哪些不同类型的存储卡？他们的规格是什么意思(specs mean)？
2、储物空间
在购买下一张存储卡(memory card)之前，请阅读要插入的设备的用户手册，并查看支持的最大存储容量(storage capacity)。来自不同制造商的不同设备使用存储卡(memory card)的特定最大尺寸。您的智能手机可以使用最大 256 GB 的存储卡(memory card)，而您的旧数码相机可以使用最大 32 GB 的存储卡。另一方面，您的笔记本电脑可以使用高达 1 TB 的存储卡。(memory card)您不希望将预算浪费在购买容量不被您插入的设备所接受的存储卡上。(memory card)
我们的建议是选择容量至少为 32 GB的存储卡。(memory card)此存储大小(storage size)适用于所有设备，并确保您有足够的空间来存储各种内容：图片、视频、应用程序、文件等。金士顿(Kingston)以及其他制造商提供多种存储选项，从 16 GB 到 512 GB 或更多。完美的尺寸取决于您打算如何使用存储卡(memory card)以及您使用它的设备的规格。
如果您是需要用于智能手机或傻瓜相机的(point and shoot camera)存储卡(memory card)的普通用户，那么 32 GB 或 64 GB 就足够了。如果您打算在笔记本电脑或平板电脑(laptop or tablet)上存储文件并扩展存储空间，则选择 128 GB 或更大的存储卡是一个更好的主意。像金士顿的 Canvas Select Plus(Kingston's Canvas Select Plus)这样的卡对于没有特定需求的休闲用户来说是一个合适的选择。它提供了充足的存储容量和良好的整体性能。
但是，如果您打算拍摄大型 4K 视频，您可能需要具有 256 GB 或 512 GB存储空间的(storage space)金士顿 Canvas React MicroSD(Kingston Canvas React MicroSD)之类的东西，它既具有大尺寸又具有更高的速度。这导致我们购买存储卡(memory card)时要考虑的下一个标准：
3.速度
存储卡(memory card)的速度对于有特定需求的专业人士来说很重要。例如，如果您使用专业相机、无人机或运动相机进行 4K/8K视频制作(video production)，您应该选择高速V90 级别的(V90 class)存储卡(memory card)，例如金士顿 Canvas React Plus(Kingston Canvas React Plus)。
如果您是专业摄影师，同样适用于在DSLR 相机(DSLR camera)上快速连续拍摄照片并将其保存为高分辨率RAW 格式(RAW format)。该卡具有高达 285MB/s 的出色传输速度和高达 165MB/s 的记录速度。它甚至捆绑了一个MobileLite Plus microSD读卡器(Reader)，可以将您的工作快速传输到您的笔记本电脑或 PC(laptop or PC)上。
对于大多数消费者而言，存储卡(memory card)的速度并不那么重要，金士顿产品组合中的任何消费卡(Kingston)都(consumer card)应该是合适的选择。
4. 耐力
如果您计划在工业环境或消费类设备（如运动相机(action camera)、行车记录仪或保姆相机）中使用(dash cam)存储卡(memory card)，那么您应该将耐用性作为选择标准。您可能需要一张可以在沙漠高温(desert heat)或冰冻以下条件下、高湿度环境等环境中使用的存储卡。(memory card)他们可能还需要抵抗冲击、水或 X 射线。对于消费者，金士顿(Kingston)提供其高耐用性 MicroSD 存储卡(High-Endurance MicroSD Memory Card)。
对于使用运动相机(action camera)记录他们的冒险经历的户外爱好者、使用保姆摄像头远程监督孩子的父母或使用行车记录仪的司机来说，这是一个绝佳的选择，因为(dash cam)它必须承受大量的阳光直射或低于冰点的温度。
对于工业环境，当必须具备耐用性时，金士顿(Kingston)提供其工业温度 MicroSD UHS-I 存储卡(Industrial-Temperature MicroSD UHS-I Memory Card)。
5. 应用性能等级
如果您想在智能手机、平板电脑或笔记本电脑中使用存储卡(memory card)并在其上安装应用程序，最好选择具有A1 或 A2 应用性能等级的(A1 or A2 application performance class)存储卡(memory card)。
此类存储卡经过优化，可与移动应用程序配合使用，并提供用户期望的必要响应能力和速度。(responsiveness and speed users)您可以在Kingston Canvas Go! Plus microSD和Canvas React Plus microSD。
6. 保修
要考虑的另一个方面是您要购买的存储卡的保修。(memory card)有些型号的保修期为 2 年，有些为 5 年，而其他型号则提供终身保修。鲜为人知的品牌与金士顿(Kingston)等知名品牌之间的区别在于，后者倾向于提供延长保修期。例如，金士顿的大多数(Kingston)存储卡(memory card)，如消费者友好的Canvas Select Plus microSD 卡(Canvas Select Plus microSD Card)，都有终身保修。
7. 价格
大多数人的预算有限，选择存储空间大、速度快、耐用且保修期长的存储卡(memory card)可能会变得昂贵。这就是为什么最好确定对您最重要的功能并选择能够在您的预算和您想要的特性之间提供最佳平衡的存储卡。(memory card)
你买的是哪个内存卡？
我们希望在本指南结束时，为您的设备选择最好的存储卡(memory card)不再是问题。您(Did)是否找到了适合您需求而又不花钱的模型？在关闭之前，请告诉我们您购买了哪张特定的存储卡(memory card)以及原因。
7 criteria to use when choosing the best memory card for you
Memory cards are found inside all kinds of devices: profeѕsional DSLR cameras, surνeillance cameras, dash cams, smartрhones, tablеts, and laptops. We even use thеm for Nintendo Switch consoles. Some devices (like digital camеras) require a memory card for their primary storage. Others (like tablets and smartphones) need them to increase their storage space. Memory cards are available in many sizes, formats, speedѕ, and storage capacities. Mаking ѕense of everything may feel daunting. To help you out, we have created this guide that covers the most important criteria to consider when buуing your next mеmоry card:
NOTE: This guide covers the basic principles involved when choosing the best memory card for your needs, applied to Kingston's portfolio.
1. The type and physical size of the memory card
First of all, clarify what type of memory card you need. It depends on the device(s) in which you're planning to use the memory card. You may have a DSLR camera that works only with CompactFlash cards, like Kingston's Canvas Focus CompactFlash.
You may need a versatile SD card that can be used both in the standard SD format and microSD, like Kingston's Canvas Go! Plus microSD. Such cards can be plugged into multiple devices like digital cameras, tablets, and smartphones.
Memory cards come in different types and sizes: Compact Flash, SD, miniSD, microSD, and so on. To familiarize yourself, and understand the differences between them, read: What are the different types of memory cards? What do their specs mean?
2. Storage space
Before purchasing your next memory card, read the user manual of the device where you are going to plug it and see the maximum storage capacity that is supported. Different devices from different manufacturers work with specific maximum sizes for memory cards. Your smartphone may work with a memory card of maximum 256 GB, while your older digital camera may accept a maximum size of 32 GB. On the other hand, your laptop may work with memory cards up to 1 TB. You don't want to waste your budget on purchasing a memory card with a capacity that is not accepted by the device(s) where you plug it.
Our recommendation is to choose a memory card that has a capacity of at least 32 GB. This storage size works with all devices, and it ensures that you have enough space for storing all kinds of things: pictures, videos, apps, files, and so on. Kingston, as well as other manufacturers, has many storage options available, from 16 GB up to 512 GB or more. The perfect size varies based on what you plan to do with the memory card and the specifications of the device(s) you're using it in.
If you are a casual user who needs a memory card for a smartphone or a point and shoot camera, 32 GB or 64 GB should be enough. If you plan to store files and extend the storage on your laptop or tablet, choosing a card with 128 GB or more is a better idea. A card like Kingston's Canvas Select Plus is a suitable choice for casual users who don't have specific needs. It offers plenty of storage capacities and good overall performance.
However, if you plan to shoot large 4K videos, you may want something like Kingston Canvas React MicroSD with 256 GB or 512 GB of storage space that has both a large size and a higher speed. And this leads us the next criteria to consider when buying a memory card:
3. Speed
The speed of a memory card is important for professionals with specific needs. For example, if you do 4K/8K video production using professional cameras, drones, or action cameras, you should choose a memory card with a high-speed V90 class, like Kingston Canvas React Plus.
The same applies if you're a professional photographer taking photos in rapid succession on a DSLR camera and saving them in high-resolution RAW format. This card has excellent transfer speeds of up to 285MB/s and recording speeds of up to 165MB/s. It even bundles a MobileLite Plus microSD Reader to quickly transfer your work to your laptop or PC.
For most consumers, the speed of the memory card is not that important, and any consumer card from Kingston's portfolio should be a suitable choice.
4. Endurance
If you plan to use a memory card in an industrial environment or inside consumer devices, like an action camera, a dash cam, or a nanny cam, then you should consider endurance as a criterion of selection. You may need a memory card that can function in desert heat or below freezing conditions, in high humidity environments, and so on. They may also need to resist shock, water, or x-rays. For consumers, Kingston offers its High-Endurance MicroSD Memory Card.
It is an excellent choice for outdoor enthusiasts who record their adventures using an action camera, for parents who use a nanny cam to supervise their children remotely, or for drivers using a dash cam that has to endure lots of direct sunlight or below freezing temperatures.
For industrial environments, when endurance is a must, Kingston offers its Industrial-Temperature MicroSD UHS-I Memory Card.
5. Performance class for apps
If you want to use your memory card inside a smartphone, tablet, or laptop, and install apps on it, it is a good idea to choose a memory card with an A1 or A2 application performance class.
Such memory cards are optimized to work with mobile apps and provide the necessary responsiveness and speed users expect. You can choose between Kingston Canvas Go! Plus microSD and Canvas React Plus microSD.
6. Warranty
Another aspect to consider is the warranty for the memory card that you want to buy. Some models have a warranty of 2 years, others of 5 years, while others come with a lifetime warranty. A difference between less known brands and established ones, like Kingston, is that the latter tend to offer extended warranty periods. For example, most memory cards from Kingston, like the consumer-friendly Canvas Select Plus microSD Card, have a lifetime warranty.
7. Price
Most people have a limited budget, and choosing a memory card that has generous storage, high speed, endurance, and a long warranty, may turn out to be expensive. That's why it is a good idea to identify the features that are most important to you and choose the memory card that offers the best balance between your budget and the characteristics you want it to have.
Which memory card did you buy?
We hope that by the end of this guide, choosing the best memory card for your devices is no longer an issue. Did you find a model that is suitable for your needs without breaking the bank? Before closing, tell us which specific memory card you have bought and why.
