Macbook air 2017 ssd upgrade

The Samsung "EVO" series SSDs do not enjoy a good reputation among Mac users.

I suggest shopping for an SSD from OWC / MacSales: https://eshop.macsales.com/shop/ssd/owc/macbook-air/2013-2014-2015 They make internal and external SSDs that are guaranteed to work.

Other options are possible, but you should avoid PC-centric vendors that do not support Macs.

What product did you have in mind?

Generally speaking if a product's specifications do not explicitly confirm macOS compatibility, do not buy it.

I understand. You're welcome and good luck.
