SD and microSD cards have evolved considerably since their introduction and are now being used for a whole host of applications. Understanding the differences is key to supplying the right card for your customer. Whilst fit and form remain the same in 95% of applications, demands on the cards are different. Knowledge of these demands and of the limitations of each technology can help your customers save time and money. Last year Simms supplied 1.6m+ SD and microSD cards for use in numerous applications across many market verticals.

Top 5 reasons for SD card failure


10 questions to ask your customer:

  1. What application are the cards being used in?
  2. What function will the card be required to perform e.g. store data, boot O/S etc.?
  3. What file types, sizes and frequency are they hoping to use the cards with?
  4. What are the environmental demands put on the cards and how accessible are they?
  5. Have they considered how long the cards must operate for?
  6. How long will data need to be stored and accessed for?
  7. What happens if data is lost and who does it impact?
  8. What problems do they have with their current cards, e.g. data loss, performance, bricked cards?
  9. What made them choose their current cards?
  10. What are the resource implications of data loss or other issues?

Consumer v Industrial – know the difference

Industrial markets include: aerospace, defence, transportation, infotainment, energy, communications, medical and marine. These industries require high performance storage solutions that will last for years and perform every time. They can be in remote locations and operate in extreme environments 24/7, 365 days a year.

 Key features of industrial cards: 

  • High durability & data retention
  • Data integrity
  • High performance
  • Highest quality components (SLC, aMLC & MLC NAND flash)
  • Controlled BOM
  • Wide operating temperatures (-40°C to 85°C)
  • Full technical support – repair/replace service

Additional benefits of industrial cards include:

Customisation – Options include power settings, formatting, conformal coating, labelling & content upload.

Product registration – Helps reduce costs, manage supply control & track BOM costs.
