The refreshed MacBook Air features a 13.3-inch display with a 2560x1600 resolution, and is powered by an Intel Core i5-8210Y, a 1.6GHz dual-core Amber Lake CPU with integrated UHD Graphics 617. It also comes standard with 8GB of LPDDR3-2133 RAM and 128GB or 256GB of SSD storage, as it pertains to the models that are on sale.
Here is how they are priced on Amazon...
Those are some tasty discounts, so long as you are willing to swallow the stunted drive speeds. Multiple sites are reporting that the SSDs used in the newest MacBook Air models run slower than the ones in the previous generation MacBook Air.
The good news for the average user is that those speed comparisons are largely academic. For many tasks, including general purpose computing, the slower read speeds are not going to be noticeable. At all. And in a vacuum, topping the 1GB/s mark is still extremely fast for tasks that feed on storage. SATA-based SSDs, by comparison, top out at around 550-580MB/s on the top models.
That said, the read speed degradation is a bummer for folks who might actually benefit from faster read performance. While still fast in their own right, a 500-700MB/s decline compared to last year's model is significant. We imagine it's a very small subset of users, though, who will find ~1.2GB/s reads to be unacceptable.
