High Capacity Sdhc
Is the Hi-density as well as SD SD High Capacity (SDHC)?

I recently bought a Dell Inspiron laptop which has an 8-in-1 card reader. The manual tells the reader to accept "Hi Speed-SD and Hi Density-SD" cards. But an Internet search for "Hi Density-SD cards found nothing. Does anyone know if "Hi Density-SD" is the same as SD High Capacity (SDHC)?

The high capacity SD cards are the ones "More than 2 GB" and bought several of these PNY SAN DISK SD high capacity 4GB cards on sale during Black Friday in November after Thanksgiving only discover they are not compatible with all computers and Digital Cameras … so if your laptop DELL accepts is only half your solution …. that we have 3 DELL Notebook PCs: Inspiron E1505/6400, Latitude D620 and Latitude D800 and so far, have had to stay with 2 GB of disk SD San bec which is mainly used in our Digital Camera. I hope the above information helps!
