Year after year cameras are getting better and require more and more data transfer rates from SD cards! In this article we propose the best SD memory cards for DSLR 4K video recording, especially considering the speed of writing and reading of memory cards.
The latest cameras have features that can cripple SD cards and put them on strings! 4k video with very high frame rates like 120fps and very long photographic bursts need an SD card to keep up!
Are you looking for an SD card to use in your DSLR and would you like to have some advice on it? Have you already looked at some SD cards but do not know how to evaluate their technical features? Do not worry, if you have five minutes of free time I can give you one hand and help you choose the best SD memory cards for DSLR.

Which SD you should buy for DSLR cameras?

Let’s start by saying that there is no perfect SD card for everyone. Or rather, there are high-end SD cards that are suitable for all uses, but so expensive, then recording only a few HD videos or taking some photos would be an unnecessary waste of money. To understand what SD card is best suited to you and avoid spending more than you owe it, you have to carefully consider the camera model in your possession and, above all, the use you intend to do.
SD cards, in addition to having different storage capacities, also have read and write speeds of different data: features that determine card performance and delimit their potential usage scenarios (eg if they are suitable to video recording in 4K or less). If you want to know more and want to find out which SD buy for DSLR camera, read on: find everything explained below.

How to Choose an SD memory card for DSLR camera?

We just said SD cards are not all the same. But what are the technical features that need to be considered before purchasing one? Let’s find out immediately.

SD or MicroSD

The Reflexes use standard SD cards, but there are also good microSDs on the market that are supplied complete with SD adapter. Nothing prevents you from purchasing a microSD and using it in a Digital SLR camera using an adapter, but this could affect the card read and write performance. If you need high performance, for example to record videos in 4K resolution, buy a standard SD card or find confirmations about the fact that the SD adapter included in the microSD you are about to buy non-casters card performance (many Adapters stop at 30MB / s).
If you do not need high level performance, and in addition to DSLR, you want to use the card on devices such as smartphones or tablets, buy a microSD as well: you will save and you will find yourself with a multi-purpose card.

Storage capacity

The SD cards are classified with the letters indicating their storage capacity.
• The standard SD offer up to 2GB of space.
• The SDHC (SD High Capacity abbreviation) have 4-32 GB capacity.
• The SDXC (Extended Capacity SD stands for) may have a capacity from 64GB to 2TB.
For DSLR I recommend up to 32GB cards, but if you are not interested in the videos and just want to take photos, you could also be happy with a 16GB card.

Speed classes

The speed class of SD (and microSDs) is another very important factor that you should consider. Each class indicates the minimum speed with which the data on the card is written, and from this parameter it is understood what purpose a card can be used for.

Class 2 (C2)

It indicates SD with a minimum writing speed of 2 MB / s. These cards can only be used for basic operations, such as creating single-image or standard definition video. They are not suitable either for HD video production or for long photographic gusts.

Class 4 (C4)

It indicates SD with a minimum writing speed of 4 MB / s, which can also be used to produce HD and Full HD video (although it is preferable to limit the resolution to 720p).

Class 6 (C6)

It indicates SDs with a minimum write speed of 6 MB / s, which can be used quite smoothly for HD and Full HD video and medium-range photographs.

Class 10 (C10)

It indicates SD with a write speed of at least 10 MB / s. These cards are suitable for HD, Full HD and high-resolution photos.


These are the abbreviations that classify the SDHC and SDXC cards with an optimized bus for recording continuous data flows. The bus is the hardware component that manages the data exchange with the device. Cards of this type are thought to be ad hoc for recording high quality video and photos, which is what interests us in Reflex optics. The SD UHS-I provides a data transfer rate of up to 50MB / s to 104MB / s, which, compared to the UHS-II standard, guarantees a transfer speed of 156MB / s to 312MB / s (provided that DSLR is compatible with UHS-I and UHS-II standards).

U1 and U3

These are two abbreviations concerning UHS-I and UHS-II cards. They indicate, respectively, SDs that can provide a minimum data write speed of 10 MB / s to 30 MB / s. They are the most advanced cards you can currently find on the market, the ones you can use to make 4K video or capture more video streams in HD quality at the same time.

Video Speed Class

Starting from 2016, SD cards are also classified according to the minimum speed with which videos are recorded on them. V6 cards record video at 6 MB / s, V10 at 10 MB / s, V30 at 30 MB / s, V60 at 60 MB, or V90 at 90 MB / s. If you are planning to record videos in 4K resolution, purchase a V30 or higher class card.


This acronym is exclusively on microSDs that have been certified for use as main memory on Android devices. They provide 1,500 IOPS in reading and 500 IOPS in writing, but this should not be very important in terms of use with a DSLR or Reflex camera.
It should be emphasized that a single SD can have multiple classifications at the same time. Therefore, it is possible to find cardss reporting the speed class (eg Class 10) plus the technology used by the bus (eg UHS-II), the U1 / U3 parameters and the classification for the Video Speed Class (eg V30).
With this in mind, we can say that the most suitable SD memory cards for DSLR camera are the UHS-I and UHS-II type.

Weather resistance

If you intend to use your DSLR in pretty busy situations, it could make you feel comfortable with an SD card that can withstand weather. On the market there are many SD and microSDs that can withstand water, impact, extreme temperatures and X-rays. They cost a few Dollars more than those less resistant to weather, but I think the price difference is worth.
