I wonder if SSDs will ever gain an additional level of hierarchy, such as an NVRAM layer over the flash layer. "Hot write" zones could then live in the NVRAM layer and only be committed to flash infrequently.
If you're willing to pay $50/GB, the STEC ZeusIOPS and TMS RamSAN provide something like this. For affordable SSDs I expect DRAM caches to range between tiny and nonexistent.
