In the last decade Flash cards became the most important digital storage support. It is difficult to identify a single killer application (digital photography, MP3, digital video, …) or whether the success of this media support is due to its usability in different applications. It is also difficult to state whether the recent revolution in the infotainment area has been triggered by the availability of highperformance NAND Flash memories or if the extraordinary success of Flash cards is a consequence of the establishment of new applications. In any case, independently of the cause–effect relationship linking new digital
daily life, it is sufficient to imagine as they would change our recent habits if the NAND memories disappeared suddenly. To take a picture it would be necessary to be used to record a video or to listen a song, and a cellular phone would return to entertainment. The development of NAND Flash memories will not be set down on the mere evolution of these digital systems since a new killer application can trigger a further success for this memory support: the replacement of Hard Disk Drives (HDD) with Solid State Drives (SSD). The advantages of SSD with respect to HDD are countless (higher read/write speed, higher mechanical reliability, random access, silent operation, lower power consumption, lower weight, …). Nevertheless, the cost per gigabyte is still significantly favorable to HDD and the success of SSD will depend only on the performances that they will succeed in reaching
