This is a bad idea. Other than the ludicrous cost of the SSD, flash drives tend to fail all at once. bam! and all your data is gone. This is also why i do not use a USB key for backups.
On my system everything is dumped on a 2TB mirrored system (simple 2 x 2TB HDDs running debian software encryption + RAID lvm) and periodically backed up to blu ray DLs in duplicate. At $10/disk from japan (see ebay) two verbatims back up 50GB in duplicate for $20.
Typically it takes 2-3 months to generate that amount which means its cost effective. DVDRs (Taiyo Yudens) fill the gap if there is not enough data to justify a bunch of blu rays.
