ASUS GL502VS whats difference between those two SKUs ?

Edit: I´ve pringed ASUS and will share their reply within this thread

Hello NBR Community,

as i´m new at current ASUS lineup and pretty interested into the GL502VS series, i´m wondering whats the diference between those two SKU´s here as both have same specs (8GB VRAM, 8GB DDR4, 6700HQ, 256SSD+1TBHDD)

Asus ROG GL502VS-FY045T (EAN 4712900495379)
5400rpm drive

Asus GL502VS-FY088T (EAN 4712900520484)
7200rpm drive


Both listed at amzn within my country, both got absolutely same specs+ both windows 10, as i know SKU is pretty interesting at other manufacturers alike MSI where I´m able to lookup the sku numbers, i am wanted to pick the "better one" for my bugs.

Additional questions:
- I hope all GL502VS have GSYNC IPS displays (am i right here?)
- the m2 slot can handle nVME(PCIE) or SATA3 SSD`s (m2 2280) (as i have 512Gig model left)
- the 2,5inch bay where HDD is inside, is capable of SATA-III (and not SATA-II as it´s in some other laptops)?

Can anyone please help ?

many thanks, aVa
