Performance Testing: Not All 2013 MacBook Air SSDs Are The Same
Wednesday, June 12th, 2013 | Author: OWC Michael and OWC Ron
Weve received two models of the new MacBook Air yesterday and have started some of our initial testing on the machines.
The SSD form factor has indeed changed as Apple is the first to adopt and incorporate PCIe storage, but rest assured we are working hard and fast to get you the upgrades youve come to rely on from OWC. Were on it!
In the meantime, we have noticed a vast difference in write speeds between the two SSD offerings that weve received so far. The 512GB Samsung SSD found in our 13-inch model offers roughly a 400MB/s increase in write speeds over the 128GB SanDisk/Marvell SSD as our 11-inch model was configured. It is our assumption that the write performance is mainly due to NAND densities and not brand performance in these cases, but well know more once we can run the same tests on a few more models.
