Im looking to get 2 Sandisk extreme pro SD cards, i was browsing amazon and found two of the same(?) item:

https://www.amazon.com/SanDisk-Extreme-UHS-I-Flash-Memory-x/dp/B005LFT3UW/ref=sr_1_4_acs_ac_1?s=pc&ie=UTF8&qid=1542764375&sr=1-4-acs&keywords=sandisk+extreme+pro+64gb

https://www.amazon.com/SanDisk-Extreme-UHS-I-Memory-SDSDXXG-064G-GN4IN/dp/B01J5RHD58/ref=sr_1_2?s=pc&ie=UTF8&qid=1542764437&sr=1-2&keywords=sandisk+extreme+pro+64gb

I notice one of them has the symbol V30 on the card and is somehow a little cheaper.

Is there a difference between the two or is one just a newer version?
