Here we have a Class 2 type card that is economically priced.  This could seem attractive for those looking for a large storage capacity at alow price.  However, be careful as Class 2 is synonomous with a minimum writing speed of 2 MB/s and this can penalize a camera in burst mode.

Poor in writing, average in reading and respectable in a reflex

We can immediately say that in writing this card doesn’t fare too well.  With 3.73 MB/s with the 256 MB files it was the slowest of our survey.  In reading, it is also the slowest, but this is still a speed of 14.91 MB/s or 17% less than the current best cards.   Finally, in burst mode slowing down occurs upon the tenth photo, or almost 1 less than the average.  In practice, this means an average speed of 1.07 ips for a series of 30 shots, while the average for other cards is around 1.55 ips.

Performances below other cards

This card is reserved for those on a very tight budget and users that don’t often use their burst mode.
