Just for a reference of someone who did at least close to this:http://webpages.uncc.edu/~jmconrad/ECGR6185-2008-01/notes/SD_CARD_DISPLAY_MICROCONTROLLER.pdf these guys did it.
Code here ftp://ftp.circuitcellar.com/pub/Circuit_Cellar/2007/209/Davaine-209.zip .
Discussed here https://www.raspberrypi.org/forums/viewtopic.php?f=44&t=135915 .

http://electronics.stackexchange.com/questions/29010/sd-card-emulation even suggests that SPI wouldn't be enough but that modern SD cards go "25Mhz".. what's the issue?How would you implement this?
Also any more references on this forum would be much appreciated.

Can I use the Espruino to emulate a SD memory card?
I.e., I plug in a microSD (via some kit hopefully even more useful than http://www.ebay.com/itm/TF-Micro-SD-To-SD-Card-Extension-Cable-Adapter-Flexible-Extender-For-Car-GPS-YG-/112084033724 ) to the GPIO pins, and the Espruino will emulate a block device i.e. block-read and block-write commands.
What speed would I get?

DrAzzy, thanks for responding -
What is the easiest-to-plug-in microSD breakout for the Espruino Pico of which you're aware that it's for sale anywhere?

Hi,
Is a ready-soldered/ready-to-use Espruino Pico + microSD breakout combo for sale?
Do you feel that that would be relevant at all?
Thanks,

Hi,
Very sorry if this is a repeated conversation -
Can I use the Espruino to emulate an USB mass storage device?
E.g. I flash the Espruino with my custom software, and when I plug it into a desktop, it will appear as a mass storage device?
..That delivers say the contents of a microSD card. If I would set up that, how many MB/sec throughput would that Espruino-microSD "DIY USB-microSD adaptor" likely have?
Thanks!
Tink
Em, maybe this one is on this topic too, not sure: https://hackaday.io/project/6435-sd-card-sized-board-lets-say-sduino .
