When you can't detect the original speed! Please choose this original Sandisk card reader! This card reader is specially used to read the Sandisk memory card. Click the card reader to learn more!↑↑↑Click to buy Sandisk Mobilemate USB 3.0 Reader
Use the Sandisk Mobilemate USB 3.0 Reader plugged into a USB 3 port. The type of reader you use for speed tests makes a huge difference.
When you used one of the cheap card readers(USB2.0), the maximum speed was only about 25 MB/s for each card. So make sure you use a reader with a good controller for the test. Otherwise, The speed will not reach the speed of the card itself. So it is not the SD microSD cards that are to blame for the lower speeds, but the "old" hardware that does not support the newer technology.
FOR A1 / A2 CARDS, A NEW CARD READER IS REQUIRED IN ORDER TO APPROXIMATELY REACH THE SPECIFIED VALUES!

FAQ
How many pictures can my memory device hold?
The following assumptions were made to calculate the number of images per card: MP = 1,000,000 pixels 1MB = 1,000,000 bytes, 1GB = 1,000MB TIFF image has 24 bit color depth, one of 16,777,216 colors per pixel JPEG 100% Quality = Visually lossless JPEG compression with 1:10 ratio of RAW image Photos - Compressed (JPEG 100% quality) Images per card.
Why do I get a "The disk is write-protected" message when I transfer files to my SD card?
SOLUTION 1 - Unlock the memory card. There is a Lock switch on the left side of the SD card. Make sure the Lock switch is slid up (unlock position). You will not be able to modify or delete the contents on the memory card if it is locked. SOLUTION 2 - Toggle the lock switch. If the lock switch is loose and moves easily It is likely the switch is sliding to the locked position as the card is placed in your host device. In this case the card will need to be replaced.
How do I format my memory card, flash drive or device using a PC?
NOTE: All SanDisk memory cards and flash drives come pre-formatted and do not need to be formatted out of the box. Memory cards are formatted with the following standards: SD/microSD- 2GB or lower:FAT16 SDHC/microSDHC- 4GB to 32GB: FAT32 SDXC/microSDXC- 64GB or higher: exFAT CompactFlash- up to 128GB: FAT32 CompactFlash- 256GB: exFAT Reformatting may clear file system corruption and quickly erase everything on the device. If re-formatting is needed, follow the steps below. WARNING: Backup all your data before formatting. Formatting will erase all data on the memory device.
What is the difference between Speed Class and Speed Ratings for SDTM/SDHCTM cards?
The speed rating measures maximum transfer speed for reading and writing images to and from a memory card, expressed as megabytes per second. However, video doesn't need as big a data pipe because the video format is a smaller "fixed stream" that uses only a portion of the data pipe. Unlike card write speeds that measure maximum performance, class ratings measure the minimum sustained speed required for recording an even rate of video onto the card. The class rating number corresponds to the transfer rate measured in megabytes per second. Class 2 cards are designed for a minimum sustained transfer rate of 2 megabytes per second (MB/s)1, while Class 10 cards are designed for a minimum sustained transfer rate of 10MB/s2.
Why do I see the SATA Link Speed is 6.0 Gb/s in Device Detail page when I connect the SSD to a USB 2.0 port using a SATA-to-USB adaptor cable?
The SATA Link Speed is the speed that is negotiated between the USB cable and the SSD, which is not the interface speed between the USB cable and the host platform.

Warm Tips:
How to verify the Capacity and Speed of the memory card?
1). Please use quality
USB 3.0
card reader to verify all memory card by   H2testw on PC. Real memory card should pass H2testw with no error.
2). Please don't use cheap card reader to test Micro SD card, speed of Micro SD card will be reduced by low quality card reader.
3). Micro SD memory card speed is greatly affected by card reader and the capacity you choose , USB port ect. Low quality device will 100% slow down card speed,1MB=1000KB.
