Last week Apple updated its MacBook Air line. The update itself was very modest and within the hardware, only one thing was improved - the processor, the clock of which was increased by 100 Mhz for all basic models. The second news was somewhat more positive, because Apple reduced the price of all models by $100, which was reflected in the Czech Republic by reducing prices by up to CZK 1.

Server & Hosting MacWorld tested the new MacBooks and compared them to the older models from last year that the update replaced. The test was conducted on two models with identical specifications, namely the basic 11-inch MacBook Air with 4GB RAM and 128GB SSD and the 13-inch MacBook Air with 4GB RAM and 256GB SSD. Both processor performance and disk speed were tested. As expected, increasing the clock rate brought little improvement, specifically 2-5 percent by operation, from Photoshop to Aperture to Handbrake.

The surprise, however, was the speed of the SSD disk, which is significantly slower compared to last year's model. Tests included copying, compressing and extracting a 6GB file. According to the table below, you can see that drives of the same capacity (lower capacity SSDs tend to be slower in general) showed a difference of tens of percent: 35 percent when copying and 53 percent when extracting a file. Blackmagic Speed ​​Test also produced similarly worrying results, measuring 128/445 MB/s (write/read) for the 725GB drive on last year's model, while it was only 306/620 MB/s for the new model with the same capacity. There was a smaller difference with the 256GB disk, where last year's model showed values ​​of 687/725 MB/s versus 520/676 MB/s of the updated version. Especially the 128 percent difference in write speed for the 30GB version is quite worrying.

Results are given in seconds, lower results are better. Best results are in bold.

The tests also revealed that the computers contained drives from a total of three manufacturers: Samsung, Toshiba and SanDisk. It is the change of disk that could be behind the worse measurement results. So if you're planning to buy a new MacBook Air, we recommend getting the 2013 models on sale or waiting for a major update in the summer or fall.
