Tests MacBook Air 1.8 GHz with SSD
Finally, one person ( Ben Drawbaugh ) managed to put Xbench 1.3 in the Apple Store on the 1.8 GHz MacBook Air with an SSD on display. Then, these results were combined into one table with previous results of testing the 1.6 GHz model (with a regular disk).
In general, the results were expected. The 1.8 GHz processor gives a small performance boost. However, the biggest increase in speed comes from using the SSD when reading non-sequential data, since No need to move read / write heads. Just as expected, the SSD is a bit slower with sequential write, but very short search time compensates for this.
Usually, a disk reads and writes “sequential” data in such cases as loading a large file into memory or saving it to disk. Inconsistent read / write operations usually occur when accessing small files that are “scattered” across the entire disk (for example, at boot).

The test results are shown in the table below (clickable)

Also, the use of SSD should increase the battery life of the laptop, but there are no specific numbers yet. The disk upgrade option costs $ 999 on the American Apple Store website.
