Solid-State Drives Will Not Replace Hard Disk Drives - Apple Co-Founder

?I don't see [SSD] kicking all spinning disks out. In computers we have so many tiers of storage for cost efficiency. Even when you have a hard disk drive it has its own cache built into it. Then we have caching systems in operating systems. Then we have different speeds of memory from your RAM to your L1, L2, L3 caches. [?] It cost more money per bit to create NAND flash,?
said Steve Wozniak in an interview with Computerworld.
...
The low cost-per-gigabyte argument is usually repeated by high-ranking executives of hard drive companies, who naturally recall the main advantage of HDDs over NAND-based storage. However, as the cost of NAND gets lower, whereas the cost of platters and mechanics inside hard drives does not, SSDs and HDDs reach crossover point, where the prices of different types of devices with similar storage capacities become equal. Once the crossover point is reached, SSDs win, claims Mr. Wozniak.

If you are talking 64GB or less, it's less expensive to have flash solid-state drive now,? said the chief scientist of Fusion-io.
...
It is interesting to note that the co-founder of Apple sees SSDs in enterprise as a form of cache, not as primary storage option.
...
?I look at [PCIe] as a more efficient, more direct connection to the high-speed bus. That's where you want it.
...
Why do you want to go through extra boards to cables to more boards and cables and then transfer it back? Skip all that middle-man stuff. That's the same way I thought when I was designing computers, storage and disks. Re-visualize the entire problem,? said Mr. Wozniak.
