thanks for your quick response.
I think i will go for the open-rd base system as it is 'only' about 40 € more than the sheeva or wait for the e-sata plug. I got basic soldering skills but there is surely more needed than that. :-)
I want to use the sheeva-thing as follow up to my nslu2 (NAS & media server) and additionally using NAS in RAID1. So i'm interested in network performance (smb) when using sata. Did you tested it and if yes can tell me your results?
again thanks in advance
