Guides for ordering buy SD Card in Bulk from MRT


Let’s learn some stories of SD Card before the shopping.

The big family of Memory cards has consisted of SD Card, Micro SD Card , CF Card, MMC Card , Mini-SD, RS-MMC , MS PRO and MS Duo. However, most of them are no longer used for latest gadgets in market. SD Card has been one of the old members, it had been popular since 1999. The size of SD Card is 24mm by width and 32mm by height; also it weighs only around 2g. It is also small size but a bit bigger than Micro SD, therefore the application between them will be different. One big advantage for Micro SD is using one SD adapter, it can be easily turning to be full size SD Card; however, SD Card can’t be used as Micro SD due to the size. Can we conclude that Micro SD can replace SD card? The answer is definitely negative.

Although we can use SD adapter to achieve the transformation from Micro SD to SD, the consistent stability is not same between them. To know more about them, we’d better learn the inner structure.


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 stabilization for them is declining one by one. 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 bigger size and 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. The logo for it is usually using sticker, it is more flexible than TF Card; also it has lock button on the shell, this is unique design for SD Card. With this lock button, the data inside can be protected from copy or read; it is one special characteristics of SD Card.

Based on the introduction above for the SD structure, the purchase of SD card will be easy and simple, as you will know well of which device will use the SD card.


What kind devices use buk SD Cards often?


Due to the size issue, we can use exclusive method. 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 DLSR Cameras, stealthy Cameras, and digital video cameras. In a conclusion, as if we are using the products related to professional cameras, the best storage accompany is the SD Card.

Besides it, many old models are also using SD Card such as handhold PC, e-Books, electronic piano, and AV equipment. 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 Cards



As we mentioned previously, SD is one old member of memory cards. Therefore, the main parameter of SD card will be same as Bulk Micro SD card. 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.


To check if the bulk SD Card is Genuine SD


You may wonder why this question coming out? What does the Genuine SD Card? It is understandable that you may have these doubts, as you have known that micro SD can be turned to be SD Card by SD adapter, also the cost of micro SD is much cheaper than SD due to the size issue. 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.
