installation on a SD/SDHC/SDXC card

Hi,
a noob question:
would I please be able to install OMV into and boot from an SD if I found my HP Chromebook 14 (FALCO) bios (upgradable to a Seabios) support it?
(http://chromeos-cr48.blogspot.…tu-on-external-drive.html)
This chromebook of mine has a SD/SDHC/SDXC built-in reader.

What I'm thinking is: will it slow down the system (and therefore the overall NAS) performance?
Regarding the wear leveling problem apparently "SanDisk Extreme Pro SDHC and SDXC UHS-I Memory Cards" (and probably others) have a built in Advanced Wear Leveling and Error Correction Code engine enhances endurance and reliability (http://www.sandisk.com.au/prod…ro-sdxc-sdhc-uhs-1-95mbs/) but I'm not so sure if that's enough of not..

Thanks

Thanks David,
I hope I may give it a try soon and post the results (an 8 GB card of those is about $20/30).
