I cracked open my Acer Chromebook Spin 13 to see if I could boost the internal storage. I can’t but some models can. Here’s the answer to “Can you upgrade SSD on a Chromebook?”
Is it worth getting an upgraded Lenovo IdeaPad Flex 5 Chromebook for $80 when all you’re adding is double the storage? Yes because the storage is much faster NVMe. Here’s how much faster it can be.
Although Google lists the storage type as SSD for all three Pixelbook models, only one has a true SSD. However, the speed of your network connection is likely more important than local data transfer rates.
