15-inch MacBook Air with Single NAND Chip May See Slower SSD Speeds
The newest 15-inch MacBook Air model with 256GB of storage has been confirmed to be equipped with a single NAND chip, according to a YouTube channel called Max Tech. While this implementation results in slower SSD read and write speeds when compared to the 512GB, 1TB, and 2TB models that have multiple NAND chips, real-world results may vary from benchmark results.
Single NAND Chip Usage in 256GB 13-inch MacBook Air, 13-inch MacBook Pro, and Mac Mini
The 256GB models of Apple’s 13-inch MacBook Air, 13-inch MacBook Pro, and Mac Mini also use a single NAND chip and have exhibited 30% to 50% reductions in their SSD speeds in benchmark tests as compared to previous-generation models. Prior to this, Apple had incorporated two 128GB chips to build 256GB Macs, but with the newer models, the company has switched to using a single 256GB chip.
Impact of Slower SSD Speeds on System Performance
While slower SSD speeds may have an impact on specific tasks such as transferring files to external drives, the average customer purchasing an entry-level 15-inch MacBook Air is unlikely to notice the slower speeds. During periods of heavy workload when physical RAM is fully utilized, Macs use some SSD space as virtual memory, which can cause a slight, but not noticeable, impact on overall system performance. However, for customers who require the fastest speeds, it is recommended to opt for the 512GB storage model, which is a $200 upgrade over the 256GB model.
Larger Displays and Two Additional Speakers
The 15-inch MacBook Air model will release with the same M2 chip and overall design as the 13-inch model. Key new features of the 15-inch MacBook Air include a larger display and two additional speakers. Orders can be placed for the laptop currently, with pricing starting at $1,299. The 13-inch model now has a lower entry-level price of $1,099.
