Next, because you're not likely to simply swap out the OWC SSD for the factory drive without migrating data over, you'll want to perform a Time Machine backup to an external drive. Upgrade the to the latest version of OS X - in this case it would be El Capitan v10.11.4. How to perform the SSD upgradeįirst things first. In other words, the OWC SSD had slightly slower performance than my factory installed SSD, but the difference was not noticeable. It revealed a maximum read/write speed of 700MBps and 423MBps, respectively. Using BlackMagic disk benchmarking software, I tested the Aura PCIe SSD once it had been installed. I was excited to see just how much faster OWC's SSD would push the MacBook Pro's performance. As expected, it was blazing fast, offering up to 723MBps sustained reads and 661MBps writes. Prior to installing a new OWC 1TB Aura SSD, I performed a performance benchmark test on my factory installed 256GB PCIe SSD using BlackMagic software, a free app. They also come with native AES 256-bit encryption and a three-year limited warranty. The OWC Aura PCIe SSDs offer up to 763MBps sustained read and 446MBps write rates. The OWC PCIe SSDs allows you to increase the capacity on your MacBook Pro up to eight times that of the factory drive and it offers up to 5.8 times faster performance than Apple's factory installed drive. But, when you already have an SSD, the next best upgrade is a bigger SSD. It improves both performance and reliability. I've said it many times before: Adding an SSD to your computer is the single best upgrade you can perform for the money. 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).
