In addition to Micron's traditional solid state drives announced today , they also showed off a concept for a SSD module that resembles RAM in physical design and would fit into a similarly designed port. It's obvious but genius: while the SSD drives with SATA interfaces are terrific because they can be used in current laptops with no mods, the real performance of flash mem is only going to be unlocked when we cast aside the legacy of spinning disks and their cases and interfaces and mount SSDs on the mobo like we do RAM modules.
The design uses a SATA interface and is only 4 mm thick. Micron claims the advantages of such a design are the small size and the ability to line up multiple drives next to each other. In addition, this design requires no wires or attaching the motherboard with screws, reducing the risk of the SSD becoming disconnnected or loose inside a computer. While this product is nowhere near ready for market, Micron says they would need to work with an OEM or someone who can offer a compatible computer solution. [Micron]
