In the older versions of the new laptops Apple MacBook Pro drive can not be replaced
As you know, the youngest of the new laptops Apple MacBook Pro has a removable SSD. It is not easy to get, and connector the drive is proprietary, but it’s still better than soldered to the system Board decision, if to speak about repair or replacement.
As it turned out, the older laptops of the new generation SSDS are made differently. It is soldered on the Board, so no way to replace it is not, and in case of failure of at least one of flash memory chips, most likely, will either have to change the whole motherboard or buy new laptop.
This is the first MacBook Pro where the drive can’t be replaced. And not to say that that’s the price for compactness, because the most accessible version with 13-inch screen still has a removable SSD.
