I am extreme sandisk card user for years. This range allows you to have rather effective rates while remaining within reasonable prices. I have two extreme 16GB Sandisk cards 60MB / s and therefore this card replaces pleasantly. Yes 120MB / s it goes fast ... In fact 2 times faster than my previous cards. Now my only limit seems to be that the buffer of my DSLR (Canon 5D MII). The transfer is done on my Mac at lightning speed, thanks to a card reader USB 3.0 (LRW300U Lexar Professional). The 32 GB are not too because I do photography in RAW and each file is larger than 25MB. Generally I needed 2 to 3 cards of 16GB for a photo shoot, there with this card I almost want every time with only one! This is handy. A beautiful card that fully meets my needs and expectations, SanDisk also offers one year of using a photo restoration software after accidental deletion. To have had the use once or twice, it's a great idea! Be careful not to activate the software during its use, this will save you having an expired license in a crash that would happen in a year.
