Internal Chip and Structure Difference
The chip for SD memory card is twice bigger than TF Card (referred to Micro SD), then the NAND flash used for SD is usually SLC or MLC; TF Card adopts MLC or TLC. These are one kind of memory technology for memory cards, the rank among them is SLC, MLC, TLC and QLC, and the stability decreases progressively. As SLC and MLC solution are easily produced by the PCB board in larger board, it’s the reason of the Size difference, we can confirm that a bigger size means better performance. SD structure is similar to the USB Drive; both of them are composed by shell and chips. The shell of SD is usually black or blue, but it is also available with colorful design as if clients have demands.

Due to the size issue, we can use exclusive method to sort out the devices using SD card. The devices such as mobile phones, tablets and Mp3 will not work with SD Card, as they have limited spaces. Also there are some devices available for both cards, for example, GPS, Dashcam, Raspberry Pi and Sport camera. Meanwhile, some devices only take SD card as their first and sole storage, these are DSLR Cameras, stealthy Cameras, and digital video cameras. Obviously, photographers or videographer concern more about SD cards. As the quality of SD card will direct affect their videos and photos. In a conclusion, as if we are using the products related to professional cameras, the best storage accompany is the SD Card. Besides it, people who still use e-Books, electronic piano, and AV equipment are in high demands of bulk SD card. It is because of the launch time of SD card prior to the Micro SD card, the slot for storage part is specifically designed for SD Card.
The important parameter of SD
As we mentioned previously, SD is one old member of memory cards. Therefore, the main parameter of SD card will be same as Micro SD. SD Card also follows the same specification of speed, it has three ways to classify the speed, and there are Class, UHS and V version. Let’s review the details for the speed. Class 4: Max writing speed is 4MB/S Class 6: Max writing speed is 6MB/S Class 10: Max writing speed is 10MB/S UHS-1: writing speed is 10MB/s, and reading speed is as fast as 60MB/s or higher UHS-3: writing speed is 30MB/s, and reading speed is as fast as 60MB/s or higher V60: the minimum writing speed is 60MB/s V90: the minimum writing speed is 90MB/s With the instruction of speed, you can easily know SD with different speed work with diverse devices. To make the purchase, you could follow the order list below. Class 4/6: low-end cameras, ATM Machine, Bluetooth speaker and the other gadgets supporting slow version. Class 10/UHS-1: high-end camera, stealthy camera, Dashcam, GPS and any electronic devices supporting SDHC. UHS-3/V60/V90: Industrial equipment, High-resolution video camera, and any 4K devices.

Obviously it is one good way to make profits by this loophole, how we identify and avoid it? There are two simple ways to find the truth. 1. We must disassemble the SD Card, and check the chip inside. If the manufacturer makes cheating, you will find one micro SD inside instead of normal chipboard. 2. We can check the function of lock button, if we could lock the data from copy or read by this button, then it is genuine SD. We have to be very careful of every detail when starting to place any orders, otherwise the loss will be unavoidable.
