Hello I intend to use a SD Card to store data in real time. In worst case the data rate goes up to 32kByte / sec. I'm a little confused about the information I found about the SD Card. I found on the datasheet of SanDisk that the block write access time is typically 24ms and 250ms in worst case. As I understand a block is the same as a sector. (512Byte) With these Information I calculate that I can write typically around
20kByte / sec (512/0.024) and 2kByte (512/0.250) in worst case. These low values make no sense to me. (A commercial camera working with SD card needs newer 20 sec. to store a 500k picture to the card). So I think I misunderstand something. What is a realistic write speed to a SD card?Thank you
