Re: pb with sheeva plug and usb/sd memory cards

Hello again,

just an idea : I can find cheap "old SATA 3G" SSD disk + usb box. Should
it be a good solution? For, say, 50 $, I can get 32 GB and those SSD
seems much more reliable.

I'm interested in your opinions (and in answers to my first post!)

thanks ahead
