Difference between SD Memory cards and SDHC and SDXC

Over the course of more than ten years, SD card development has been formally documented. During this time period, drives went through numerous generations, expanded their maximum memory capacity, increased their speed, and became more commonplace for the typical person who uses technology. What are the differences between SDHC memory cards, SDXC memory cards, and SD memory cards? We will also discuss the characteristics of these drives, as well as how to select the most appropriate drive for your device.

An SD drive is distinct from an SDHC drive and an SDXC drive.

Varieties of SD

Secure Digital is what the abbreviation SD means for by itself. Beginning in the year 1999, this category of media has been generated. Obviously, in our day and age, no one utilizes cards in their original form for reasons that are self-evident. The creators, throughout the course of time, started to improve the qualities and volume, resulting in the release of new generations, which will be explored in further detail.

Capacity is the primary distinction, as was briefly discussed above. Nevertheless, the read/write speed and support capabilities of various devices (cameras, phones, and so on) are entirely different from one another. A total of three types are available:

SD; SD High Capacity; SD eXtended Capacity are all supported.

To further understand the distinctions between SD, SDHC, and SDXC memory cards, let’s examine each of its qualities in isolation.

Volume difference

MicroSD is the type that has been around the longest and has the fewest claims. In version 1.0, the first generation can only store up to 2 gigabytes of data, however in version 1.1, it can store up to 4 gigabytes of data. When compared to the size of the high-quality films and photographs that are produced by modern smartphones and cameras, these figures are currently considered to be extremely insignificant regarding the modern consumer. It is possible that such media is only useful for the transfer of small files. There is no rationale behind the act of expressly purchasing such stuff. It is a file system that uses the FAT16 format.

SDHC cards are the second group of cards. When compared to standard SD cards, they are distinguished by the greater quantity of storage space and file system. By utilizing the FAT32 file system, the maximum capacity has been increased to a maximum of 32Gb.

SD eXtended Capacity is the format that is the most up-to-date. 2009 was the year that the standard was formally established, and it continues to be in high demand even today. The SDXC standard, which differs in volume, is capable of accommodating up to 2 terabytes of information, which is a significant increase from the previous generation. ExFAT is the file system, and it also supports formatting in the FAT32 format.

the primary distinction between SDHC and SDXC memory cards, which is something that you should take into consideration when selecting a drive for your device of choice.

Device and operating system support

All devices that have the suitable slot are able to support the SD generation as of the year 2017. For the time being, any and all devices that are only capable of supporting the SD standard will be unable to read data from HC or XC media. In order to be compatible with all three generations, cameras and smartphones that support SD eXtended Capacity must be compatible. There are no compatibilities with older versions.

In terms of the operating systems that enable SD, it is also possible for SD to be differentiated from High Capacity and eXtended Capacity:

Because to exFAT, the Windows XP operating system does not accept SDXC drives unless a special update is installed. On the other hand, the Macbook and Mac OS have supported SD eXtended Capacity since 2011. Additionally, flagship Android devices support SD eXtended Capacity. In order to use any other smartphone or tablet, you will require a specific driver that is manufactured by Samsung.

Difference between Micro and Mini

Now, let’s examine the differences between MicroSD and MicroSDHC memory cards and their Mini equivalents from a technical standpoint. The size difference is the primary distinction, as you could have guessed. In order to accommodate apparatus that is more compact, a Mini version has been developed. This version is typically supported in smartphones and is typically put in the second SIM card slot. MicroSDHC, SDXC, and SD are distinguished from one another by the fact that they are able to connect to the card reader without the need for an adapter, whilst the Mini version entails the use of an adapter.

Speed ​​difference

Now that we have that out of the way, let’s have a look at the variances in information reading speed that exist between all SD, SDHC, and SDXC memory cards. There are four different speed classes that are marked on the case of each drive: numbers 2 (from 2 MB/s), 4 (from 4 MB/s), 6 (from 6 MB/s), and 10 (from 10 MB/s). Based on the fact that the class designation represents the minimum write speed, it is possible that the performance of a single drive is higher in actuality. Rather than indicating qualities in accordance with the accepted classification, manufacturers indicate them in megabits per second. Additionally, both SDHC and SDXC are capable of supporting Ultra High Speed technology, which can reach speeds of up to 25 megabits per second.

Pay close attention to the type of drive and the capacity it has when selecting one. These days, SDHC and SDXC are still relevant. It is also important to confirm the media’s compatibility with the device for which you are purchasing it before making a purchase in order to avoid any incompatibilities.
