It's more a thought experiment at this moment than anything else.
http://www.dealextreme.com/p/sdhc-sd-card-to-sata-solid-state-hard-drive-22597
Coupled with a Class 10 8GB SDHC card.
The goal is to run the computer (which is a headless server so there won't be much writing to the card after installation) from the SDCard, freeing up the remaining drives to function as just storage devices:
2x500GB in RAID 1 for Time Machine backups of my MBA.
1x1TB for movies
1x1TB for TvShows
1x500GB for Music
I know the sustained write speed of a C10 SDHC card is 10MB/s, which is slower than the 3GB/s SATA interface it will be on. I can't get any figures on read speed, tho some averages for various manufacturers is up to 200x, which would be 2GB/s.. so not too bad.
Either way, is this possible/advisable for a server? Or would I be better off just partitioning the Music drive into a 400GB / 100GB and using the smaller portion for Ubuntu?
(As a side note, is an Intel Core 2 Duo@2Ghz enough oomph to handle RAID 1? Or I am better off scrapping the whole idea and shelling out for a hardware RAID controller?)
