After 50 years, the useful life of the hard disk drive (HDD) is increasingly being threatened by SDRAM and flash-based semiconductor solid state disk (SSD) storage. For example, Samsung Electronics Company has announced plans to release a 64GB solid state disk drive in a 2.5-in. form factor with an IDE/ATA or Serial ATA interface.

And, Has the HDD reached the physical limits or can the technology be pushed further?
