I was wondering if I use arduino with an USB Host shield and a sata drive attached to an SATA/USB converter I could access the data on the drive to copy to another drive, I want to make an automatic backup tool, ...
I know that I could just buy one of this, but I guess I just want to do it myself to know how-to.
In theory it is possible,
In practice forget it.
The throughput of the Arduino is much much much lower than what USB3.0 can do. (don't have figures, but I expect it is lower than 50KB/sec)
Get a Raspberry PI for this. @700Mhz it is 50 times faster than an Arduino.
unless you only need to copy less than a few MB...
robtillaart - beat me to it, I was going to start with exactly the same phrase:-

However I was going to say that you would have to write the drivers to work with that devce if you got a USB Host shield. It comes with little actual software drivers.

I could, but I want to do something really cheap, just for fun, and in Brazil Raspberry Pi costs about R$ 200,00 or for you US$ 100,00.
import taxes are quite high in Brazil, I heard that before.
imho An Arduino is just not capable of doing this.
Better check the local 2nd hand shop if they have an old motherboard you could use?
These 2nd hand stores are also good places to get little motors leds, switches etc from toys or tools.

Yeap, really high, my next project will be an C4 remote trigger to blow some dirty politicians heads!

It's really hard to get electronics parts here, when I want I have to buy online almost everything, and if some store have the part that I want to buy, I have to pay taxes to the goverment and to the brazilian store because when they import the part they want some profits, and they also pay taxes to the goverment, so I prefer buy online and just pay the goverment once.
LoL
Thanks for the tips guys, I guess first I will make the C4 project, then, with no taxes I could by another raspberry pi hehehe...
Anyone knows where I could buy C4 ?
man i wouldnt even say that online. i dunno the political climate where you are, but here they really got no sense of humor about that these days. we all know youre joking, but it could in theory be used against you, out of context. that being said, make a model rocket launcher.
