What's the best after-market SSD for my MBP?
The best available data are not yet good enough to separate fact from fiction on SSD reliability among vendors or even as compared to spinning metal.

There's an excellent review at Tom's Hardware that explores what is currently known about SSD reliability.

From the article:


  ... Many of the IT managers we interviewed reiterated that Intel's SLC-based SSDs are the shining standard by which others are measured. But ... there's nothing to suggest that its products are significantly more reliable than the best hard drive solutions. We don’t have failure rates beyond two years of use for SSDs, so it’s possible that this story will change.
