Sequential writes were 35.36MB/s to 446.55MB/s, averaging 252.68 for the OWC, and 25.28MB/s to 232.12MB/s, averaging 140.33MB/s for the standard SSD.

Finally, random writes were 34.86MB/s to 445.86MB/s, averaging 236.48MB/s for the OWC and 24.33MB/s to 232.79MB/s, averaging 123.57MB/s for the standard SSD.

The bad news is that my machine also ran hotter with the OWC drive inside, and the fan began to kick in even for simple operations like using Chrome with five or six tabs open.

Verdict

There's no arguing the OWC drive is way faster than a stock SSD, but the question to ask yourself is really whether that increase in speed is of any real benefit to you. You'll also trade off fan noise, which is going to hit battery life too. It's not a cheap upgrade either, so it's really only worth doing if every ounce of speed is essential to you. ®
