Tried many SD cards and Lexar turned as most reliable for me. Sand Disk Extreme PRO died after 5-6 month, two PNY cards died after 8 month and now using two Lexar Premium very intensively and they are just great! I also have few other cards but using them only as backups.

Like Sandisk, I've never had any problems with the Lexar memory cards both CF and SD - The 600x speed cards are fast enough for my needs as a portrait photographer using a Nikon D800 shooting in uncompressed raw format.

The product is very good.

Easy To Set Up; Easy To Use; Fast; Portable

Excellent card for DSLR camera. Write speed is excellent. Just for comparision... I shot 79 pics in one minute with this card but as in Sony memory card i can shot only 45 pics in one minute.Yeah its coming with higher price tag.I bought this card @ 1180/- rupees.

I purchased the 3-pack of these 64GB cards. For the price the value is excellent. The MAJOR questions with any storage media are 1. Reliability 2. Speed. Since I've just received these I have no data on reliability but the vast majority of SD cards by reputable manufacturers do not fail.

For now, I did use it as a USB Flash Drive Device. It's for both Mac & Windows based PC. I had download Full HD 1080p without compress 1 hour movie clips in fairly quick time. Fast write and very quick reader to another computer at the fullest capacitive.
