Reliable as ever

I purchased the extreme micro Secure Digital High Capacity memory card to film up to 4K videos and to capture burst shooting in still cameras. In burst mode several photographs are captured in quick succession and this is where the speed of the memory card comes into play.
Some background info that you may find helpful. For any given memory device, there are two speed specifications that are provided by the manufacturer and these are namely, the read and write speed. The faster the read speed the more rapid is the rate of data transfer to your computer.
The higher the write speed the faster the images are saved onto the memory card. A Class 2 speed translates to write speeds of 2MB per sec. This is the sustained writing speed as opposed to the maximum instantaneous write speed. So the number shown on the memory card is the sustained write speed. Therefore a class 10 card will achieve 10MB/sec.
I've used other brand 'high speed' (class 10) cards in the past and I found that during the shooting process, on occasions you can experience dropout or jitter. I have not experienced any such problems with the Sandisk extreme cards.
There are plenty of cards out there that will do the job if you are just shooting standard photos or even capturing standard or HD quality videos. It is worth noting that image quality is unaffected by the type of memory card used. However using a low speed (say class 2) will process the information more slowly. It may also be less reliable and may corrupt you data more readily when used in high demanding applications.
I purchased this item at full price. If the product is unworthy of a good review, I think it is unfair to leave positive feedback as this can mislead potential buyers. I hope you found the review helpful. Please click on the “Yes” button below.
