Attachment Turns MicroSD Cards Into a 640GB SSD
microSD SSD creator kit, will let you find use for the microSD cards you could have lying around, and create a cool little solid state drive for your use. This would be extremely useful for people who have plenty of cards lying around. Having those cards work as an SSD would make them quite more useful. The device can accept 10 cards, going to a maximum storage of 640 GB. At $87, the price is a bit of a bummer.
are you sure it’s 640gb ? i calculate 1280gb with ten of these cards below.

The maximum storage capacity would generally be (also) governed by the processor on this attachment and the bus it uses. In this case, it seems the usable memory will top off at 640gb, irrespective of the number or storage capability of the cards.
