With the release of the Agility 4 series solid state drives, OCZ leverages the Indilinx Everest 2 platform featuring SATA III 6GBs transfer speeds, as well as incorporating the latest technology when it comes to NAND flash memory to create some of the most reliable solid state drives available today.
Another new feature for the Agility 4 series is NDurance 2.0, a cutting edge management suite developed exclusively for Indilinx solid state drives. NDurance 2.0 handles multilevel ECC, adaptive NAND flash signal processing as well as the Redundant NAND Array (RNA).
Shown in this photo is the heart of the Agility 4, the IndiLinx Everest 2 controller. The Everest 2 is surrounded by eight flash memory chips on both sides of the PCB; the two smaller IC chips seen in the photo are the DRAM memory that the controller utilizes.
Here we have a block diagram for the Ndurance 2.0 technology. Built into the advanced Indilinx Everest 2 platform, Ndurance 2.0 is a sophisticated memory management suite that greatly increases the life span of NAND flash memory based solid state drives. It features multilevel ECC technologies including Redundant NAND Array functions along with adaptive NAND flash management. Ndurance 2.0 significantly lowers write amplification without the loss of performance caused by data compression

Regardless, in recent years SSDs have been doing better than HDDs in every category except cost per GB, longevity, and total capacity, having resolved poor write times some time ago. Now it seems a matter of finding a cost-effective way of getting high capacities out of these without compromising endurance and making it so it costs even less per GB and it would be a viable alternative to HDDs for everyone.
That is, assuming they've also solved that issue with SSDs not doing so well after 10's of thousands of rewrites? I guess HDDs still have the edge there too?
If so, there is always the next generation of storage. I don't remember the details, but I know they're working on it.
