Have your SD cards been filling up and collecting over the years? If so, you'll eventually want to offload those photos and files. And the best way to do that—if you don't already have a card reader embedded into your computer or laptop—is to buy one that connects externally.
Card readers come in all sorts of shapes and sizes, with all types of connectors. They don't just read SD cards; some can read microSD cards, CompactFlash (CF) cards, and even Sony’s Memory Stick Pro Duo.
To find the best SD reader for your machine, we tested those that connect either via USB or by way of USB Type-C. The latter is a type of connection standard that's become more widely used, and manyApple laptops，，，，Chromebooks，并且超级本仅带有这种端口。
在计算市场上八个最佳SD读卡器的速度时间之后，我们发现我们最喜欢的是Unitek Y-9324BGY（（available at Amazon）. Not only did it hail some of the fastest write speeds from the batch of readers we tested, but it also offers a multitude of connection options. The Unitek is a worthy card reader for anyone who needs to get their data off of a memory card.
以下是我们测试的最佳SD读卡器：
我的名字叫佛罗伦萨离子，近十年来，我一直在为专业购买建议。我也是一个专门的Chromebook用户，经常正在寻找USB Type-C配件，可以帮助您从DSLR来回传输照片。
I bundled together nearly 30GB of varying file types, including RAW images, JPEGs, GIFs, ebooks, text files, Word documents, and videos to test the write speeds of each card reader. The test was split up into three stages: moving over 10GB of data, then 20GB, and then nearly 30GB. The tests were conducted three times apiece, each time measured by a stopwatch, and the final results were then averaged to determine each card reader's top write speeds.
并非所有的读卡器都使用同一台计算机进行了测试。使用Windows 10笔记本电脑对USB 3.0兼容的读取器进行了测试，而USB Type-C读取器则通过MacBook Pro进行了测试。
为了测试每个读取器的读取速度，我使用了一个名为USB Flash基准测试的程序来测量PC上的USB 3.0连接卡读取器，并在使用Mac测试的USB-C读卡器上测量了USB。Sandisk Extreme Pro 32GB，它tested the fastest in our SD card test，，，，served as the benchmark for each card reader since it can handle up to 95 MB/s transfer speeds.
As you're shopping for an SD card reader, you should consider things like speed, size, and overall ease of use.
If your laptop has a USB-C port (many models these days only have one to work with), you'll want to stick with that type of connection for your card reader. If you have a laptop with traditional USB ports, there are also two USB 3.0 options tested here.
左侧的USB-C连接器比右侧更传统的USB 3.0连接器变得越来越普遍。
Don't bother with USB 2.0 card readers, as they're generally considered an outdated standard and are much slower than what's out now. USB 3.0 card readers are also backward compatible, so they're worth checking out even if you have an older computer.
您不必购买所有插槽的读卡器。例如，如果您没有较旧的数码单反相机，请跳过CF阅读器，因为它也可能会为您节省一些房间。CF卡大于SD卡，因此需要更多的住房。插槽越少，读者越小，如果您想保持光线充足，读者会很好。
Removable cables are nice, but if you're always on the go, consider a card reader with one that's permanently attached. Cables can be easily misplaced, which can later cause a headache. Also, just because a card reader is small and compact doesn't mean it offers you access to all of your computer's ports.
