PSA: Apple using slower SSDs in some MacBook Air models (video)

When you head to Apple's online store to configure your MacBook Air, you'll find options to increase processor speed or SSD capacity -- depending on the model you select, of course. There's no mention of flash drive speed, however, though it's now clear that not all SSDs are created equal at Apple -- not only when it comes to capacity, but also performance. Jonathan over at TLD discovered a fairly significant discrepancy when benchmarking both MacBook Air models over the weekend. The 128GB Samsung SSD in his 11-inch Air was able to achieve 246 MB/s write and 264 MB/s read speeds. When he switched to the 13-inch model, however, speeds dropped to 156 MB/s and 208 MB/s, respectively, using that notebook's 128GB Toshiba SSD. We compared speeds on two generations of 13-inch models, and confirmed Jonathan's findings. During our tests, the 256GB Samsung drive in our older model achieved 214 MB/s write and 251 MB/s read speeds, while the 128GB Toshiba drive in the new MacBook Air scored 184 MB/s and 203 MB/s during write and read tests, respectively. Overall, you're not likely to notice a significant difference during normal usage, though it's certainly an interesting find, nonetheless.
