SDHC

Back in the old days the disk drive manufacturers used to have to come out with a whole new interface standard every three years or so as the disks they were making exceeded the maximum capacity of the old standard.

So now the flash memory people are doing the exact same thing. Standard SD cards are limited to 2Gb so a new standard called SDHC has been introduced with a maximum capacity of 32Gb. Not too bright when there is already an 8Gb card on the market. The new standard will last us for at best three years.

Why not just go straight to 1Tb or so? The new cards require a new reader which means that all the people who paid for a card reader in their monitor are going to find it quickly becomes obsolete.
