How to connect hdd/sdd to raspberry pi?

Question

Microcontrollers

The task of the device is as follows: when a flash card is connected and a button is pressed, the device creates a folder in the root of the internal drive (ssd / hdd / paired flash cards) with the date and time and overwrites all information from it. Files prioritized by ~ 7Mb. in total at a time ~ 32GB or less. Accordingly, the write speed should be high. The device should not read files - only write. Since I don't know much about this, I'd love to hear your opinion.

Answer 1

All we have in the Arduino to provide an exchange with media is a UART and a stone at 16 MHz, i.e. it is hardly possible to count on a speed of more than 115 Kbps. This is quite enough for logging some events. But in order to score these gigabytes at such a speed ... you can grow old faster :) You definitely need something like a Raspberry Pi, this is at least.

Answer 2

At a minimum, you need a serious driver that can communicate with the hardware and read fs. Another thing - really, why? There are ready-made shields with memory cards.

Answer 3

the option that comes to mind is ARM devboards
for example Cubietruck (Cubieboard3) or similar, and the performance is higher and SATA is present
