Third Generation Solid State Drives

Solid State Drives

        The basic system architecture for an SSD will be described to help visualize the main components that assist in the wear-leveling algorithm. Below is a simple block diagram of an SSD. Data transferred to and from the SSD passes through a Host interface chip that is configured for different interfaces like PATA, SATA, SCSI, SAS, etc. The host interface is connected to two buses, a system bus used for addressing and control, and a data bus that provides the data path to the NAND flash. On the control bus is the CPU, Flash controller and static random access memory (SRAM). The SRAM is used for tables, CPU scratch pad computing and logical block to physical block address mapping. 

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.


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. 

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.

 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. 


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.
