Synchronous NAND enables reads and writes to be “synced” with the SSD processor’s clock signal for maximum data throughput. 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. OWC SSDs are engineered to be the best for Mac, undergoing a rigorous 7-stage lab testing process to deliver absolute reliability at maximum performance long into the future. Better by Design Aura Pro 6G SSD for MacBook Air 2012 is designed and built with premium tier-1 NAND flash. Unlike the factory pre-configured models with no other SSD choices offered, the OWC Aura Pro 6G gives you the freedom to choose from a variety of sizes to meet your storage needs. OWC’s Aura Pro SSD provides up to nearly 16x the capacity of your MacBook Air’s factory SSD, while offering faster performance. Now thanks to OWC and the Aura Pro SSD line, you can buy the MacBook Air you want today and enjoy higher performance whenever you’re ready to upgrade. The SATA cable is the weak link, one of many reasons Apple went to the PCI-e and soldered-in storage.Designed for Mac 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 16X 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. They can be damaged quite easily if the unit is mishandled during assembly or re-assembly. This type of cable can experience cracks in traces due to aging, heat, vibration, impact and abrasion. Those SATA cables are actually not cables but flexible circuit boards, usually mylar, with printed circuit traces taking the place of wires. As it cools down, electrical contact may once again be restored. As a unit heats up, it expands, and as it expands, the crack widens, eventually forcing a complete electrical separation to exist on both sides of the crack, hence a failure. In the case of an intermittent generic failure, the electrical continuity of a cracked trace on both sides of the crack is very often a function of the temperature of the unit at the point where the crack exists. It is however no mystery why old cables fail when switching from HDD to SSD. Agreed, a new SATA cable is a nominal expense and highly recommended.
