It seems that during this decade we are going to witness many technological replacements. The DVD player will be replaced by HD DVD or Blu-ray player and the regular CDs and DVDs will be replaced by high-def discs. The latest in replacement, according to SanDisk Corporation is the hard drive which will be soon replaced by solid state drive (SSD). SanDisk has launched a 32GB, 1.8-inch solid state drive (SSD) as a replacement for the standard mechanical HDD. With no moving parts, it does not need to spin into action or seek files in the way that conventional hard disk drives do. According to company, this device is more than 100 times faster than most hard disk drives. A PC equipped with Sandisk SSD will boot Windows Vista enterprise in 35 seconds with an average file access rate of 0.12 milliseconds, compared with 55 seconds and 19 milliseconds of a PC with a traditional hard drive. It is also more power efficient than regular HDD.
The SSD achieves a sustained read rate of 62 megabytes (MB) per second and a random read rate of 7,000 inputs/outputs per second (IOPS) for a 512-byte transfer. By including NAND flash and SanDisk’s TrueFFS flash management technology, the SanDisk SSD delivers two million hours mean time between failures (MTBF). It is projected that inclusion of the SanDisk 32GB SSD in a notebook PC could increase the end-user price by around $600 in the first half of 2007. The 1.8-inch 32GB solid state drive is now available for original equipment manufacturers.
