Sucks to be us, eh? :)
A write to a FLASH device requires that either existing data be moved, or that existing data be re-written in place. This is because FLASH data is managed in large blocks, and a block needs to be erased before it can be written. An updated block needs to be updated in device RAM before it can be written. Without an exceedingly good design, this makes me feel nervous if the power fails since data unrelated to the write could be destroyed.
Got'cha. In the case of a system crash (where the SSD retained power), would this be an issue? I'm thinking it'd be ok since that should all be internal to the drive? Or is that another unknown?
