AT2LP has a slower HDD format time than CY7C68300A

Last Updated: July 01, 2011
Question: 

Why AT2LP has a slower HDD format time than CY7C68300A?

Answer: 

Some customers have noted that the AT2LP takes longer to format a HDD than the CY7C68300A.  The CY7C68300A did not actually verify the sectors that it had previously erased.  This gave the appearance of having a very fast format time when compared to other USB bridge solutions, but it was actually not the proper way to format a drive.  The AT2LP provides the correct format procedure at a fast rate.
