How to increase SD card write speed in arduino

I'm creating a data-logger system which logs data in SD card at a high speed of about 20000-30000 bytes per second. But the SD library in arduino currently writes data at about 4500-5000 bytes per second which is too slow. I've read this hack to…

Writing to sd card with a sampling rate 50ms or less? I have a sketch that writes to sd every 1s but jams at faster sampling rates. Please help?

My code below reads data from an ADC and 3 digital pins via a Mega and prints to an SD Shield (Deek Robot). I want to be able to read the data every 50ms (20ms ideally). I can't get below 250ms. I've read countless forum posts regarding the same…

Is it possible to use extra AVR Flash memory as non-volatile EEPROM-like Flash memory storage?

In STM32 microcontrollers it is possible to use a technique that ST calls IAP, or In-Application Programming, in order to write to the Flash memory from your running application. They even have a nice Application Note (ex: AN2594) to describe a…
