Solid-state disks are bigger and better

Storage semiconductor business is becoming more and more the attention of the fans of mobile telephony. Flash memory is justified thinner, more energy efficient and has better access than the traditional calendars disks. They are the best choice for notebooks as the MacBook Air or ethereal Lenovo ThinkPad X300.

High capacity disks notes are extremely expensive, and it is very likely that you pay the price for a sports car for a 160 GB of solid-state drive. For example, the option of flash memory in the MacBook Air $ 1300 accounts for the difference in comparison to the costs, lower disk model, which sold $ 1799. Moreover, the fixed disks have a limited lifespan, if the comparison to the hard, and that a number of cycles letter (10000 cells, which for Multi-Level Flash for storage or 100000 single cell).

SanDisk has a poor performance, high-speed, 1.8-inch hard drive, which a transfer rate of 66MB/sec data at a rate of random play of more than 7000 inputs and outputs per second. This slightly exceeds the performance disk capacity several times. The company was not the look of charges for the moment, but it will certainly rise to the device reached the market. For example, a flash-memory card SanDisk 8GB now sells for about $ 80 at retailers, but a few years ago, for just $ 80 you could get a feather-1GB hard drive.

SanDisk will also Toshiba in manufacturing of 43 nanometer chip flash memory, which in solid disks reach capacity between 120 GB to 160 GB Both SanDisk and Toshiba have recently announced that they are on 32 Gigabit (Gb) the density the chips. By N. Khandker cube, SanDisk vice president of flash memory design and product development, 32 GB, with the many levels of battery technology, so that more bits to store twice the storage capacity for DBVARIANZ.

SanDisk is also working on a new technology called "X3", given the opportunity, in the company 3-bit memory cell. "This is an important (and) we can 3bits/cell unlike 2bits/cell thus the efficiency of production," he said. "Then, a combination of technologies of the scale (c 'means that 56nm to 43nm), and bit-level (ie 2bits/cell to 3bits/cell) is extremely powerful for the manufacture of efficiency and the increase in flash memory, Claim cube.
