Reality Check

Dramatically reduce an ioDrive's write performance down to that of SandForce's controller and you will easily exceed their five-year rating.

This is because the single largest determinant of longevity is how fast one writes, and under real-world use (mixed read / write load), the SandForce controller will achieve 1/4 to 1/8 the write performance of an ioDrive.

In other words, their endurance as measured by how much data can be written to the drive over it's lifetime is actually less than an ioDrive.

That's because the second largest determinant of longevity is how many write cycles can safely be made on the NAND without risking data loss. Here, Fusion-io's unique and patent pending FlashBack Protection allows for several times more cycles - because it can tolerate chip failures and not loose data.

SandForce's longevity extending techniques are well understood in the industry, and don't significantly alter the underlying endurance cycle counts like FlashBack protection does.

Oh and yes, I'll admit I'm biased, but it doesn't change the facts.
