Macbook Air SSD memory sticks look just like DRAM sticks to me (see link), but they use a different abstraction to access them (SATA vs. DDR). Are the requirements that drove the original use of ATA still applicable with the SSD memory form-factor (e.g., seek times, etc.)?<p>http://notebooks.com/2010/11/08/toshiba-introduces-macbook-air-style-ssds/
Despite looking like memory, SSDs are not much like DRAM. They are also not much like disks either. I suspect you will see new protocols for accessing them eventually, similar to NCQ on SATA drives.
