Backup options for home

[Scott R. Ehrlich]

I'm looking for relatively cheap nonmechanical means to backup up data 
from my home Linux box.

I've been pricing 16GB Compact Flash and SDIO cards.  I'd store a 
collection of MP3s on one, and the rest of my data on another.

I've ot my eye on a TransCend 16GB CF card (TS16GCF133) and a Transcend 16 
GB SDHC memory card (TS16GSDHC6-s5w).   Some manufacturers boast Toshiba 
or Samsung memory.   How much does that really play a role, and are their 
prices relevent, or is it just marketing?

What are people's experiences with using CF and SD cards for data 
preservation on the cheap?  What is the average data storage life 
expectency for solid state devices, such as CF and SD cards, vs their 
mechanical equivalents?

Thanks.

Scott
