You're right that the FTL has some durability concerns which, in addition to performance, is why it's typically cached in DRAM. Older DRAM-less SSDs were unreliable in the long-term but that's been improving with the adoption of HMB, which lets the SSD controller carve out some system RAM to store FTL data.
