First of all, memory chips are getting smaller, reducing data paths. New NAND chips are made with 34nm chips, much like modern CPUs.

 

Second, smarter controllers are striping data between NAND chips to overcome the 16 bit asynchronous IO interface on a single NAND chip. By striping data across multipole chips, like RAID stripes data across multiple mechanical hard drives, the bottleneck on any individual NAND chip is bypassed.

Hi tpatterson,

Here's an interesting article on how can make an SSD even faster.

How do you make an SSD even faster?

"I now have four SSD-equipped systems - two desktops and two laptops - running full time. That’s given me an opportunity to try a very interesting experiment. How do you make an already fast SSD even faster? What I found is that the combination of an SSD and a disk controller upgrade can boost performance by a minimum of 50% and can triple disk throughput speeds. Here are the details."
