About SDHC Media

SDHC comes in Class 6, Class 10, Class 16 and the newest UHS-1 300X. Classes represent minimum sustained transfer speeds.

For example: - 

  • Class 6  represents a minimum of  6 MB/s
  • Class 10 represents a minimum of 10 MB/s
  • Class 16 represents a minimum of 16 MB/s
  • UHS-1 300X
  • UHS-1 633X 

Sony XDCam EX cameras will happily use some Class 6, most of Class 10 and above and now even UHS-1 300/633X memory cards.

For full overcranking the camera will require a minimum transfer rate of 10-11 MB/s which certain manufacturers can provide but, for safety and prudence the minimum of Class 10 is recommended.

However, we have happily overcranked Class 6 memory cards from ATP, SanDisk and Patriot and all these memory cards tested to be worthy of Class 12! So there are exceptions to the minimum class requirements...

MXM & Hoodman SDXC Adapters in use with SDXC Media & XDCAM recording - (Updated 8/1/12)

SDXC media is extended capacity media, up to 2T, compared with SDHC media which has a maximum capacity of 32GB. Currently, the maximinum capacity available on the market of SDXC media is 128GB. This will be extended in the future...

SDXC media's default file structure is exFAT file system, whereas SDHC media's default file structure is FAT32.

When SDXC media is used in Sony's XDCAM cameras, with MxM & Hoodman's SDHC/SDXC adapters, the SDXC media will be formatted to FAT32 file system as this is the camera's default file structure.

Since the MXM & Hoodman SDHC/SDXC adapter is COMPLIANT with SDXC memory cards, reformatting the memory card from FAT32 to exFAT file system does not represent an issue! 

Please bear in mind, that SDXC media, when purchased brand new, is by default formatted with exFAT file system.

The XDCAM camera series will format the new SDXC media upon insertion, safely to FAT32 file system.

Note, please only use COMPLIANT MXM and Hoodman SDHC/SDXC adapters to ensure trouble free formatting!


1.  Will my SDXC media, once formatted to FAT32, on XDCAM cameras, ever be able to be reformatted back to exFAT?

Only if you use MXM or Hoodman SDXC adapters...You will be able to format back and forth the SDXC media.

Caution should be taken, using a NON-COMPLIANT SDXC adapter, as it can make your SDXC memory card inoperable...

2.  Will my warranty be void if I format my SDXC media with MXM or Hoodman adapter on XDCAM camera to FAT32?

No, because the MXM and Hoodman adapter does not permanently alter the file structure of the SDXC media, rather, they comply to the host’s product’s settings.

3.  What are the speeds of SDXC memory cards?

The SDXC memory card presently are rated as:

  • Class 4
  • Class 6
  • Class 10
  • Class 10 UHS-1

The fastest being CLASS 10 UHS-1 (Ultra High Speed).

4.  How fast is SDXC media couple with the MXM or Hoodman adapters?

Depending upon the SDXC speed class used, you will get differing results.

In general Class 10 UHS-1 will give you the fastest read and write results.

For example:

Patriot   64GB SDXC Class 10 UHS-1, we were able to achieve 31 MB/s read and 18 MB/s write.

SanDisk 64GB SDXC Class 4 memory card, we could only achieve 22 MB/s read and 14 MB/s write.

Speed achieved without MXM or Hoodman adapter.

SanDisk Pro UHS-1 64GB SDXC Class 10 memory card, we were able to achieve 75 MB/s read and 45 MB/s write with USB 3.0  reader.

ATP Pro UHS-1 64GB SDXC Class 10 memory card, we achieved 55 MB/s read and 20 MB/s write using USB 3.0  reader.

Manufacturing quality of SDHC/SDXC memory cards

SDHC memory cards vary from factory to factory and country to country. For example, SanDisk memory cards are graded from professional to consumer to budget quality and the pricing will reflect this. 

Patriot can be manufactured in Taiwan and also manufactured in the USA.

Transcend memory cards come from all over the world and with other brands, they do not necessarily come for the branded name's manufacturer, rather they can be made for the manufacturer by an OEM company.

It is a well known practice, if a manufacturer runs out of one component, they will substitute it with another one, as long as it will represent the designated Class grade.

The fundamental difference between professional grade memory and non-professional, is the choice of NAND flash and choice of the memory controller and as well the quality of the casing.

Professional grade memory cards will be high quality, high performance and a durable flash product. For example, Hoodman Raw Steel, ATP Pro or SanDisk Extreme Pro.

However, other known non-professional grade memory cards we have tested, the likes of Patriot, Team or Transcend all went through the minimum 300 hours of recording without any failures and represent a good budget option for videographers not requiring the robustness of professional grade and higher priced memory cards.


  • Durability and built quality is very important and should be paramount in your choice of media.
  • SDHC/SDXC memory cards are available in different price and quality ranges: -


  • - professional grade memory cards – durability, consistent manufacturing and
  •    the built quality;
  • - consumer grade – works very well but the durability is unknown;
  • - low economy memory cards – works, need to be very careful; and
  • - cheap memory cards (bargains) which have also been tested to work and  
  •    fail immediately.
