2019 256GB MacBook Air has a slower SSD than 2018 model
根據 Consomac 的測試,在 Blackmagic 硬碟速度測試軟體中,
2019 款 256 GB MacBook Air 的讀取速度為 1.3 GB/s,寫入速度為 1 GB/s。
2018 款 256 GB MacBook Air 的讀取速度高達 2 GB/s,寫入速度為 0.9 GB/s。
這意味著,兩代 MacBook Air 的寫入速度相差不多,
但數據讀取速度新款卻落後於舊款 35%,從 2 GB/s 減至 1.3 GB/s。
100 美元的優惠就是 SSD 速度降低實現的。
當然,MacBook Air SSD 速度降低 35%並不意味著性能會降低 35%。
1.3 GB/s 的 SSD 對於日常任務來說已經足夠,
主要瓶頸還是在 CPU、GPU 和 DRAM 幾個方面。

以 Air 來說這應該不會影響太多,
不能自行更換才是可惜的地方。
