SanDisk 64GB (Two Pack) Extreme Pro Memory Card (SDSDXXY-064G-GN4IN) SDXC 4K V30 UHS-I With Everything But Stromboli (TM) Combo Reader Review

I've been using SanDisk SD cards for years - and I've never failed because of a bad card. Several self-inflicted disasters, but never the card's fault. Some even survived the spin cycle.

I don't know if it's a card or a reader but I used it in my camera and then inserted the card into the reader and imported light space . Everything went well. But when I transferred some files to the card and plugged it into another laptop, I was told that the card needs to be formatted before use. I tried again on the first laptop - same thing. Just tried a card into the built in card reader in another laptop - same thing. Now I don't trust this card or reader at all. Edit: I did a read/write…

Another great set of memory cards from Sandisk. Pop them into my new Nikon D750 and no problem. The USB card reader was new and included but is required if your laptop does not have an SD card reader. I won't be using it so I don't know how it will work.

I bought Lexar 633x 95MB/s cards but that speed was for read only! the actual write speed was around 20 MB/s. too slow (almost useless) for professional - hard - work. So I went for these Sandisk cards and the difference was like night and day. Period. These cards are very reliable and quickly empty the camera buffer.

I bought it for a safari earlier this year. My camera has two memory slots so I decided to buy it as I didn't need anything faster for the shots I was planning to take. Never again have I used one of these on a 4 hour safari trip and spent the next two hours after the charms struggled to transfer images to my computer due to bugs and poorly read messages from the cards. They're not even an option as there are no shipping options, duty and VAT would wipe out any profit.
