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.
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.
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.
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.
