- Lifetime: Actual technology provide an MTBF of at least 1M Hours. Laptop HD have MTBF of around 2M Hours. You'll replace your laptop before replacing your SSD, and you have more chance(risk) to have a failing HD than a failing SSD :) - Hotspot: the selfhealing feature of ZFS (checksum) is perfect to counter "badblocks" for dying cells.
My advice: give a try and then consider the "risks".
