Apple's SSD drives in Macbook? Are they good, or low end and/or slow?

SSD drives in Macbook: are they good, or low end and/or slow? Like, how do they compare to say the Corsair P128/P256? Are they worth it in the refurb models of the 13" Macbooks?

The SSD's Apple uses aren't the worse and but definitely not the best. So from a price standpoint, it probably woudn't be the best to buy the SSD from Apple unless you're afraid of getting a third party SSD and installing it yourself.
