NAND prices per GB are actually starting to come back down, now. Most of the 3D NAND tooling change-overs are completing at the various NAND fabs, so NAND prices should only continue to fall in the coming months/years in $/GB pricing metrics.
You can get consumer grade 500GB-class SATA 2.5" SSDs for $130 (or less!) now from multiple vendors. This time last year these were up around $200 (EDIT: this may not be accurate!). Consumer SATA SSDs were some of the first to transition to 3D NAND.

- ksec 9y agoWell it is coming down now only because Samsung is trying to lock in as much market share of NAND as possible this year, before the Chinese has their NAND Fab running and start race to bottom.
- judge2020 9y agoNote that many of these high capacities SSDs are able to sell at lower prices due to them not having any onboard dram, meaning the mapping data for wear leveling is either stored on the nand itself or in the system ram which causes random read/write to slow down a significant amount.
- bradfa 9y agoDRAM is still extremely expensive, so you're probably on-point about part of the low price being the lack of DRAM. It would be interesting to see tear downs of current consumer and enterprise SSDs to better understand how they work.
