The Difference between SD and Micro SD memory cards


Within SD card data recovery, memory cards are employed to provide a considerable amount of storage capacities drones, dash cams, mobile phones, SLRs and other electronic devices. Ordinarily, the memory card is referred to as an SD card. However, that is inaccurate as there are various types of memory cards with SD card being just one among them and the other being the Micro SD Memory card (TF). The following article will explore just what constitutes the differences between SD card and TF card.

  1. How to differentiate the sizes between Micro SD card and SD card?

The sizes between these two cards varies greatly as the size of the SD card is much bigger as compared to the Micro SD card. Now the exact size of the SD card ranges at 24 mm × 32 mm × 2.1 mm, whereas in the case of the TF card, its size measures at 15 mm × 11 mm × 1 mm. As such, it wouldn’t be correct to say that the memory card of the mobile phone is an SD card. Such a card is in fact, a Micro SD card and is also known as a TF card.

  1. The application of these two cards differ

Bulk SD card refers to secure digital card and its primary characteristics is based on the semiconductor flash memory. Furthermore, the origin of the SD card came much earlier and was the outcome of substantial research and development. The SD cards are primarily found in baby monitors, digital cameras, or even portable computers. Due to the fact that it is a flash drive, it can be utilized to store files, which are parallel to that of the USB flash dive. Having said that, you will need to employ a card reader that will enable you to write or read onto the SD card using a regular desktop computer. With the SD memory card, you will find that it is completely open standard and primarily found in MP3, e-books, digital cameras, AV equipment etc. It is very commonly used in digital cameras which are ultra-thin. On the other hand, the micro SD card is a very small sized flash memory drive and is featured in mobile phones, dash cam, GPS, drone as well as other digital devices.

  1. The maximum capacity they hold is different

As observed by SD card data recovery, there is a certain level of divergence between TF cards and SD cards when it comes to storage capacity. To be more precise, the capacity of the SD card that is available in the market is as low as 256MB, 128MB, 512MB, etc. while the capacity ranges up to 512GB as well as 2TB. But in the case of the TF card, the maximum capacity can only go up to 512GB, owing to the limitations of the volume.

  1. The security related technology differs

With respect to the security technology, SD card data recovery has observed that there is a switch for protection on the SD card. However, the TF card does not feature such a lock. Furthermore, the present SD card has been able to develop rather extreme levels of a high speed card, but the same cannot be said for the TF card.

Among the chief features of the SD card is that the encryption function enables the confidentiality and the security of the data. It is also equipped with a copyright protection enabled technology and the technology that provides copyright protection is known as CPRM technology i.e. recordable media content protection that is commonly found in DVDs. Some of the characteristics of the SD card are large capacity, small size, high temperature resistance, shock resistance, stable performance, lack of noise, permanent data storage etc. It’s also worth noting that is one such popular memory card and the SD card allows a connection to the standard ATA IDE interface. Given how it’s a device equipped with IDE storage, it is also feasible to store the software installation program.
