Solid State Disk (SSD) Will Replace Harddisk

The new Solid State Disks (SSD) will replace HDD soon, MICRON has announced two new lines of flash memory solid state drives (SSDs) using high-performance single-level cell (SLC) NAND technology, aimed at enterprise server and notebook PC applications.

SSDs offer performance advantages, power savings and reliability benefits over hard disk drives (HDDs).SSDs perform about ten times faster than HDDs, exhibiting 0.8 ms data access latency compared to average HDD data seek latency of approximately 8 ms.

SSDs consume about one-tenth the electrical power of typical HDDs, running at 0.3 watts when idle and only 2.5 watts while active, whereas HDDs usually draw between 8 to 28 watts. Since they use so little power, SSDs also require virtually no cooling, which also reduces power consumption.

SSDs are also more reliable than HDDs. Using wear-leveling technology, SSDs offer mean time before failure (MTBF) ratings of approximately two million hours compared to typical HDD MTBF ratings of between 300,000 to 500,000 hours.

SSDs for notebook PCs will come in 1.8-inch and 2.5-inch modules with capacities from 16GB to 256GB.

500 GB DVD from Pioneer

Leading hardware Pioneer has developed a technique which will allow optical drives to store 500GB of data. Nikkei Business Daily reported that the technique will use ultraviolet lasers, which emit shorter wavelength rays than blue lasers,
the beam to write data holes in a master disk, each separated by 70 nanometres.

Ultraviolet lasers are a good topic for engineering students seminar
