Which means how many bytes can be written to the flash memory before there is data loss. Enterprise SSDs have a durability rating based off of drive writes per day. So obviously enterprise SSDs are more durable across the board.
So you have to set the parameters of what data you're backing up and how often. As an FYI, SSDs are NOT considered archival grade. Hard drives and magnetic tape are still the standard as archival grade. There are also archival grade writeable optical media. The issue is if the SSD is allowed to sit for a long duration, the electrons captured in the cells of the flash memory will eventually leak out the electrons. The only way to avoid this is to energize the flash memory periodically. How long you can go without energizing the flash memory to ensure data integrity is highly dependent on the flash memory used.

Thanks to all. Thanks for the comment about non-archival aspect of SSD, I am rethinking this and reconsidering spinning disk.
