Despite the continuous improvements, price-per-gigabyte could continue to be an issue when comparing SSDs to hard drives, Forward Insight's Wong said.
"The cost per gigabyte of a 2.5-inch SSD is something like five times that of a hard disk drive," Wong said. The price difference mainly applies to the consumer space, where PC makers like Apple, Dell, and HP offer SSDs in laptops.
Samsung's Yang said the company is working with PC makers to develop SSD form factors that could fit into different laptop models.
In the server space, customers may bypass price for performance, said Michael Cornwell, lead technologist for flash memory at Sun in a recent interview. Server-grade SSDs usually perform better in certain environments like Web 2.0, where they are comparatively faster and more power efficient than hard drives.
Web 2.0 applications could drive the adoption of SSDs in the enterprise, Cornwell said. Delivery of distributed Web 2.0 applications -- like cached photo content -- may be delivered quicker from SSD nodes than hard drives, Cornwell said.
Many server vendors have announced plans to include server-grade SSDs in systems, including Hewlett-Packard. Samsung is working with PC makers and server vendors on the implementation of SSDs, Yang said.
"Most of these datacenters, when they employ a new technology, it takes a long time to ... qualify and evaluate," Yang said.
