Query: This is card running at 24X speed.

I purchased this card from the market seller "emartbuy". This card in not running at 150X speed. It's write speed is close to 3.6MB/sec(24X). Don't buy it from emartbuy if you really want a 150X card. The card is okay to buy if you don't mind the write speed(24X).
