Chapter in this post:
Buying an SD card sounds like an easier task than it actually is. Because there are different formats, a number of names and also different manufacturers or brands. So before you go to the next electronics store or one memory card ordered online, please read the following paragraphs first. If you already know whether you want to buy an SD, microSD, SDHC or SDXC card, but are still bothered by the labels, characters and numbers, then take a look at this guide: What are Class, SDHC, SDXC, UHS, I, A, V and Co.?
The size of your SD card, SDHC or SDXC memory card should be in the instructions for use of the device in which you want to use the memory expansion. MicroSD cards are usually used in a smartphone. For larger devices such as DSLR cameras or an older MacBook, regular SD models can be inserted. So my tip: it's best to buy a microSD with an adapter for SD slots. That is not more expensive and makes your mobile storage flexible to use. Whether it's a drone, smartphone, laptop, camera or dictation machine - with a small memory card and an adapter for a larger format you are always well equipped.
Several factors come together to answer this question. Because on the one hand you should of course have enough memory on the chip so that you don't have to constantly change the memory cards. On the other hand, the memory card must also be compatible with the device in which it is used. So look again in the operating instructions or the manual PDF of the device whose memory you want to expand. Some devices can handle 512 GB or 1 TB; others don't even want 256 GB, but can only be expanded with 128 GB, 64 GB or 32 GB. Old devices maybe even only with 16 GB or 8 GB.
If you are still unfamiliar with terms like Class, UHS, A, V and so on, then I recommend the link given in the introduction. In the linked post I have explained all abbreviations and values to you. Therefore, here are just a few small cornerstones for video devices (drone, smartphone, DSLR, camcorder, etc.):
I am relatively inflexible on this question: I only use SanDisk memory cards out of conviction. You can't go wrong with SanDisk, in my opinion, as you get decent quality for a reasonable price. I only buy SanDisk cards for all my devices, especially since I have a friend who had a breakdown during a photo job with a no-name SD card. Many of the photos could no longer be read at home and even a data recovery program couldn't get anything out. Sure, Lexar, Transcend, and Samsung cards aren't fake either, but personally I'll stick with it SanDisk.
Regardless of whether SD, microSDXC, other memory cards, USB sticks or external hard drives with SSD architecture - here in the blog there are now and then articles and test reports on SanDisk products. Here is a selection so that you can read about the high-quality articles:
Which memory card, which class and MB / s rate, which size in terms of SD, micro, SDHC or SDXC and how much memory you need from 4 GB to 128 GB to 1 TB can usually be found in the information on the device used . You now also know how to find the right memory card, what the individual names mean and that a small card with an adapter is probably the right one. With this post and the one linked above, you should have all the information you need. If you still have questions about buying an SD card, please leave a comment or write an email;)
