Third Generation Solid State Drives


Hard Disk Drives

A hard disk drive, commonly referred to as a hard drive , hard disk or fixed disk drive, is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Strictly speaking, “drive” refers to a device distinct from its medium, such as a tape drive and its tape, or a floppy disk drive and its floppy disk. Early HDDs had removable media; however an HDD today is typically a sealed unit with fixed media.

Strictly speaking, an HDD is a rigid-disk drive, although it is probably never referred to as such. By way of comparison, a so-called “floppy” drive has a disc that is flexible. Originally, the term “hard” was temporary slang, substituting “hard” for “rigid”, before these drives had an established and universally-agreed-upon name. some time ago, IBM’s internal company term for an HDD was file.


Introduction

The explosion of flash memory technology has dramatically increased storage capacity and decreased the cost of non-volatile semiconductor memory. The technology has fueled the proliferation of USB flash drives and is now poised to replace magnetic hard disks in some applications. A solid state drive (SSD) is a non-volatile memory system that emulates a magnetic hard disk drive (HDD). SSDs do not contain any moving parts, however, and depend on flash memory chips to store data. With proper design, an SSD is able to provide high data transfer rates, low access time, improved tolerance to shock and vibration, and reduced power consumption. For some applications, the improved performance and durability outweigh the higher cost of an SSD relative to an HDD.

Intel Corporation introduces its highly anticipated third-generation solid-state drive (SSD) the Intel Solid-State Drive 320 Series. Based on its industry-leading 25-nanometer (nm) NAND flash memory, the Intel SSD 320 replaces and builds on its high-performing Intel X25-M SATA SSD. Delivering more performance and uniquely architected reliability features, the new Intel SSD 320 offers new higher capacity models, while taking advantage of cost benefits from its 25nm process with an up to 30 percent price reduction over its current generation.

Nand -Flash Memory Array Architecture

NAND flash memory chips arrange the memory cells in a logical “not-and” (NAND) configuration. This arrangement strings together all of the cells for a common input / output (I/O) bit across all memory pages.

 Single And Multiple Level Cells

The control gate voltage necessary to form the N-channel is controlled by the charge on the floating gate. The required voltage is called the gate threshold voltage and is labeled Vth. With SLC flash memory, there is only one programmed state in addition to the erased state. The total of two states allows a single data bit to be stored in the memory cell.

Intel Third-Generation Ssd 320 Series

For the better performance of Intel Third-Generation SSD 320 Series , the intel introduces a new processor called as  Intel 3D Tri-gate Transistor for 22nm Processors . Enter Intel’s new 22nm Tri-Gate transistors which can be packed onto smaller chips than current 2D 32nm transistors while consuming less than half the power. The new transistors will also enable exciting advances in portable electronics, as they are 37 percent more powerful when operating at low voltages. Intel already has plans to produce and ship a new breed of Ivy Bridge processors that utilize the Tri-Gate transistors by 2012, extending Moore’s law well into the future.

 Conclusion

As the Solid State Drives is a new innovative technology which will provide high data transference, high data security & enhanced reliability. And the most speculious highlighting feature is, the power consumption which can be contributed by the Intel third generation Solid State Drives with the help of the Intel 3-D Tri-Gate processors.
