I have two questions from those who have an Asus x556 and tried to upgrade their storage?
first is in those models that have Ssd+Hdd together,like x556uq, where is the second drive? they replaced optical drive or both storage can fit in Hdd place? i searched all related clips in youtube but haven't seen any second storage.is second ssd of yours a m.2 storage?
My second question is there any m.2 support in this model?
For the X556UQ,
You will need to replace the Optical drive with an SSD caddy and populate the caddy with an SSD. I'd suggest leaving the HDD location as is since HDD's will need airflow, seeing how there are vents.
From this image:
The only M.2 connector is occupied with the NGFF WiFi adapter.
