Compared to the rapid performance increases and price decreases of flash memory over the past few years, solid state drive advancements have slowed down considerably in 2013 as modern drives have plateaued at SATA III's 6Gb/s bus. Current flash products are already maxing out the existent SATA spec for sequential reads and writes, so it's expected the industry will eventually move to SATA Express for bandwidths of up to 2GB/s using PCIe 3.0.

That transition will inevitably encourage an entirely new breed of SSDs as companies compete for your hard-earned cash, but until then, SSDs will become cheaper and more reliable through improved manufacturing processes.
