SD block driver - ext2 block size
Am calculating throughput for my own SD (Secure Digital) card driver. I get very less numbers of throughput for SD cards. I receive only 4KB of data for every request from the file system. I use ext2 filesystem for the card.
I believe the maximum block size of the ext2 filesystem is 4KB. So that the file system gives 4KB per request.
Is there anyway to increase the blocksize of the ext2 filesystem?
i tried "mke2fs –t ext2 –b= 8192" to change the block size but got the error as invalid block size.
