  • Intelligent Block Management & Wear Leveling automatically distributes data evenly across the entire SSD.
  • Intelligent Read Disturb Management spreads the active read/write across the flash components eliminating data corruption caused by constant use.
  • Intelligent "Recycling" for advanced free space management gradually re-writes data across the SSD over time to ensure data never gets corrupted.

More Options
Once again, OWC provides Mac users an upgrade path that delivers higher performance, functionality, and reliability! With the 2012 base model 11" MacBook Air only offering a 64GB flash module and the base 13" model offering just a 128GB flash module, installing an Aura Pro 6G flash module can increase storage capacity up to 8X higher! Plus for the upgradeable models, unlike an upgrade from the factory at the time of purchase, this OWC bundle includes an Envoy to keep that factory flash module working for you as a super fast, external storage solution!
Better by Design
"Mean Time To Failure" – We all know that nothing lasts forever. But that doesn't mean you shouldn't get the most out of your investment. OWC SSD with DuraWrite™ Technology, optimizes writes to the flash memory over conventional controllers increasing the overall endurance and reliability of the complete SSD. Highly intelligent block management and wear leveling also extends the overall endurance. This adds up to a MTTF that is higher than most SSDs and enterprise class hard drives on the market today.
Synchronous Interface NAND
To achieve the higher bandwidth potential of the SATA 6Gb/s bus standard, the OWC Aura Pro 6G SSDs utilize Tier-1 Synchronous NAND instead of commonly utilized Asynchronous NAND. Synchronous NAND enables reads and writes to be "synced" with the SSD processor's clock signal for maximum data throughput.

Rating: 2/5 This product has some defects January 15, 2013 When I got my SSD, it didn't fit in to my air. It was less than 1mm too long, but long enough that I had to modify the SSD to get it to fit.

When I put my original SSD in the Envoy, it only worked sometimes. I noticed when I plugged in the USB cable at the Envoy end, there was some sparking. I did some investigating and found out the case of the Envoy had voltage on it. See my youtube video for a quick diagnosis of this issue.

I think both of these are design flaws that should be addressed.

That said, once I got everything working, I'm fairly happy. The new SSD gets about the same write speed as the original, but the read speed is a small bit under double that of the original. The original SSD gets the same R/W speeds in the Envoy as it did internal in the Air.

Rating: 4/5 Good but speed is not 500 MB/s January 10, 2013 180GB Memory: Good reading speed up to 430 mb/s but no more than 220 MB/s in writing, macbook air 2012 11 '. I found several installation problems: - Videos are very good aid - The memory was slightly larger than a corner and had to sand Envoy Storage Solution: Very good price per pack, but a screw was swept, gave me a lot of trouble being able to get. Overall I feel good but do not expect 500 MB/s in reading and writing, note that the original memory MacBoo Air is slower than OWC 180GB Aura Pro.

Rating: 5/5 Simply Outstanding September 20, 2012 The service and product from OWC was the best I have ever witnessed from any internet retailer. The SSD was shipped from America to Rural New Zealand in little less then a week and came with all appropriate packaging and manual's. The product is great, exactly as advertised and was a breeze to install.

I purchased the 180GB OWC Aura Pro 6G Solid State Drive for a Mac Book Air that was sent to me as a replacement from an insurance company. They had devalued my previous Mac Book to a 64GB SSD so naturally I turned to Apple for an upgrade. After finding that this was not possible I then followed Google Search's to OWC. The drive itself may not be quite as fast as the 64GB Toshiba drive however as the only solution available I am extremely happy with the product. Exceptional Service and Products, Top Marks OWC.

I would recommend this item to a friend!
