Sandisk micro Secure Digital High Capacity, Class 4 Memory Card



Over the years, mobile phones have become an essential part of our modern lives. They are versatile and powerful tools which pack the very latest technology in the palm of our hands. To take full advantage of the features offered by these devices, the demand for digital storage space has increased more and more over the years.



I bought the 8GB Sandisk memory card for my smartphone. A the time, this had quadrupled the storage capacity of my device. It was the most cost effective way of 'upgrading' your phone.



For any given memory device, there are two speed specifications that you need to bear in mind, 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.



I have not experienced any problems with data corruption when using Sandisk cards. It is worth noting the 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.
