OCZ Technology Group, a leading maker of solid-state drives, announced Tuesday that virtually all of its SSDs are now based on NAND flash memory produced using 20nm-class process technology. Such SSDs are less expensive to manufacture, but many customers are not satisfied with them.

“OCZ is constantly exploring ways to not just advance solid state drive design but also make the technology more affordable, while maintaining high performance and reliability standards. We are excited to complete the transition to the next generation 20nm-class NAND components which reiterates our strategy of producing high performance SSDs at the most attractive price point available for consumer applications.”

As the industry transitions to a 20nm-class fabrication process, OCZ remains focused on delivering high-performance solutions that continue to pave the way for SSDs to become more accessible to the complete range of consumers, and to ultimately replace traditional mechanical hard drives over the next few years.

OCZ will continue to offer the older flash technology in select SSD products with a higher price per gigabyte. All of OCZ’s 20nm‐based SSDs carry the same warranty as the earlier 30nm-class versions.

But not everyone is happy about OCZ's SSDs with 20nm-class NAND flash memory. According to some end-users, drives based on Micron's 25nm NAND flash memory offer lower write performance compared to predecessors, besides, they offer lower amount of spare capacity as more bits are reserved.
