I4U reports SanDisk has developed an integrated solid state disk (iSSD) that is roughly the size of a post stamp. These tiny storage devices are thinner than a SD memory card but are capable of 160MB/s read speeds and 100MB/s write speeds. They will start shipping this quarter in 16GB, 32GB and 64GB capacities.
While this drive would work fine soldered into a laptop or desktop, SanDisk's focus here is on shipping to tablet manufacturers. They had three tablets out on display (including an HP Slate) that all used other models of SSD chip.
Actually holding the iSSD in my hand (or rather between my fingers) was a bit of a trip. It feels a little thinner than a SD card, and it's significantly smaller all around. It brags 160 MB/s read and 100 MB/s write speeds and weighs just .83 grams. These things are so small that (given the know-how) you could solder one in to pretty much any tablet out there. They take up almost no space and have an average power draw of just .18 W.
