How to find out the cache size?

Dear WD Community!

Could you tell me, how to find out cache size of WD My Passport Ultra especially 2.5 1 TB Usb 3.0 WDBGPU0010BBK(-EESN)?
I have been searching for it a long time. I can not find anyithing on WD’s webpage, users manual…
I would like to buy this one, and it would be really useful to find out the cache size.

Thank you,
