So why is my 1GIG ssd drive not the size of 8 of these microSD cards? In fact I could easily fit 16 of these cards in USB stick. Someone MAKE IT SO! :D

  I think it's mainly a matter of pin count - SATA SSDs want to be able to access the NAND devices independently in order to stripe accesses. That's how they're able to offer such high sequential speeds. So a typical SSD will include 4-8 packages containing only a few NAND dies each, rather than one or two with 8 dies each.

    We also aren't that far off with 1TB mSATA (about 1x2 inches) drives available today. 2.5" drives are obviously much bigger than 8 microSD cards because the form factor was designed for spinning platters.

      There already is a 1TB mSATA http://www.anandtech.com/show/7594/samsung-ssd-840-evo-msata-120gb-250gb-500gb-1tb-review http://www.anandtech.com/show/7594/samsung-ssd-840-evo-msata...

        But that sacrifices a lot, by using TLC (since 128Gb MLC isn't available yet), and by stacking stacking 16 dies per package, and by having less spare area than most drives. The end result is significantly lower performance and longevity than other mSATA drives, and it's currently got a 25% premium over the 2.5" counterpart.
