Memory prices for cameras, PDAs etc. are already dropping nicely. HDD prices are plummeting (£80 for a 1TB drive in PC World), while P2 is feeding the professional appetite for fast, reliable, flexible memory.
SanDisk is one of the world's largest manufacturers of solid state memory devices, and was recently a Samsung acquisition target.
Ahead of the 2009 CES in Las Vegas, Ars Technica reports that the company has announced that it soon hopes to crack the three main issues surrounding SSDs; high price, low drive capacity and poor random write performance.
Sandisk will push the nantechnology boundary a bit further and invest more in the development of multi-level cell (MLC) drives. At present, SLC drives are 1-bit per block of memory, while the new drives, which Sandisk hopes will be available in 2009, will be 3-bit and 4-bit (see diagram):

To compensate for a potential performance hit, SanDisk is also developing a new file system, ExtremeFFS.
