It was not quite as fast as OWC said it would be but it was certainly respectable.

I did a read/write speed test on my factory installed SSD once I'd turned it into an external drive using the OWC Envoy Pro enclosure and it had a read/write speed of 304MBps and 253MBps, respectively. Once you've installed the OWC SSD, you can use your Mac's original flash drive in the enclosure as a fast external USB drive with transfer speeds up to 355MBps. The kit is actually a pretty good deal because just to purchase the Envoy Pro SSD enclosure would cost you $79. You can also purchase a complete upgrade kit, which includes the OWC SSD, screw drivers, a USB standard A to micro B cable and an external PCIe SSD enclosure with USB 3.0 port for $399 (480GB model) or $649 (1TB model).
