Difference between SD card and memory card

Memory cards are typically used to extend the storage capacities of devices like mobile phones, Dashcam, SLRs, Drone, and more.

Most times, we often refer to memory cards like SD cards. But, the fact is, that’s inaccurate, as memory card comes in different types. SD card is only a type of memory card, and Micro SD Memory Card is also one of them. What’s the difference between the memory cards and SD cards? Here’s a detailed explanation.

The size difference between the memory card and SD card. 

The size of most memory cards; for example, Micro SD is different from that of the SD card.

Simply put, SD cards are usually larger than standard memory cards like Micro SD card.  Specifically, the SD card is available in a size of 24 mm x 32 mm x 2.1 mm, and the memory cards like TF card comes at a size of 15 mm x 11 mm x 1 mm. Hence it is wrong to refer to the memory card of mobile phones as SD cards. It is better referred to as a micro SD memory card.

Different application 

SD card means a secure digital card and works on the principle of semiconductor flash memory.

Moreover, SD card started in earlier ages, and are the outcome of the last century’s research and development.

On the other hand, memory cards like the TF card stand for T-Flash Card. T-flash card implements the latest NAND MLC technology.

The TF card got into the market in 2004, which was five years after the SD card was launched.

Most people commonly use SD cards in digital cameras, handheld computers, or baby monitors. Due to its flash memory features, you can use it to store files, much like a USB flash drive.

However, if you want to read or write an SD on a computer, you’ll need a card reader. SD card is an open standard system, commonly used in ebooks, digital video cameras, AV equipment, and more.

On the other hand, the Micro SD card is a small-sized memory card mostly used in GPS, mobile phones, drives, Dashcam, and other digital devices.

SanDisk invented the Micro SD format. SanDisk designed this micro SD card using the SD architecture, with a size as small as a fingernail.

It was known formerly as Trans-flash Card before the SDA association, in 2014, changed its name to Micro SD card.

Before Micro SD was launched, many Phone manufacturers use embedded memory. While anyone can easily install these modules, they are unable to meet today’s standard- because their capacity was limited. Not long after, Micro SD tapped into the SIM card application mode: it allows a SIM cardholder to allow the use of one card in different mobile phone types.

 Different maximum capacity 

When it comes to storage capacity, SD cards are different from some other memory cards like the TF cards.

Specifically, the most common SD card capacity ranges from small 128MB, 256MB, 512 MB, and more, with the maximum capacity of up to 51GB-2TB. Meanwhile, the TF card comes at a max capacity of up to 512GB, because of the volume limitation.

  Different security technology 

When it comes to security technology, the SD card has one protection switch, while memory cards like the TF card have no lock. What’s more, the latest SD has an exceptionally high-speed card. It’s not the same as the TF card.

SD features an encryption function that keeps the data secure and confidential. Another significant feature is the copyright protection technology, which is called the CPRM technology, mostly implemented on DVDs.

SD card vs. Memory card- The verdict 

SD cards are characterized by small size, huge capacity, stability, effective data storage, errorless, noiseless, and ability to resist high temperatures.

It is one of the most popular memory cards. SD card connects to the standard ATA IDE interface, allowing the storage of the software installation program.

However, while SD cards and most memory cards are different in many ways, their essence stays the same- all are memory cards. If you still want to choose these memory card types separately, then you can use SD cards in cameras, and other memory cards like the TF cards in mobile phones, dashcam, and GPS. At Hugdiy you can custom SD cards and design logo free. You will wholesale SD cards at an affordable price.

And if you’re considering the purchase costs, the TF card is the way, because you can turn them into one SD card and an SD adapter, but you cannot convert SD cards into a micro SD card.

Therefore, speaking relatively, a typical memory card can be more flexible and economical than the regular SD card.
