Solid State Drive (SSD)

Solid State Drive :-

A solid-state drive (SSD) (also known as a solid-state disk or electronic disk, though it contains no actual "disk" of any kind, nor motors to "drive" the disks) is a data storage device using integrated circuit assemblies as memory to store data persistently. SSD technology uses electronic interfaces compatible with traditional block input/output (I/O) hard disk drives.

Intel Solid State Drive (SSD)

Solid state drive 320series (SSD):-

Laptops are quickly being eclipsed by tablets which have NAND flash drive embedded on their motherboard. Operating systems like windows 7 have been optimized to take advantage of SSD input and output performance.

This product is manufacture by Intel. Solid state drive is much more reliable and fast for booting as for the normal hard drive. It shifts the pc form performance form high gear. It improves reliability, performance, and much more.  Its reading performance is up to 270mb per seconds. It also has 128bit encryption capacity to secure your data. This drive is connected with the help of SATA cable. And compatible whit minimum 1.5Gb/s.

Solid State Drive 320series

Capacity:-

Solid state drives 320series have the capacity up to 40 to 600GB.

Temperature:-

This drive has the temperature up to 70 degree centigrade.

Reading and writing latency:-

It has the reading latency of 75 µs. and has the writing latency of 90 µs. but it fluctuate on the size of drive.

Inch factor:-

Normal SATA hard drive is of 3.5inch and the SSD are of 2.5inch. SSD are smaller than the SATA normal hard drive.

Voltage Characterstics:-

It need min 4.75v and max 5.25v to run.

Different Between Solid-state drive and Hard disk drive:-

Hard Drive Drive VS Solid State Drive

Start up Time:-

Solid starte drive Almost instantaneous no mechanical components to prepare. May need a few milliseconds to come out of an automatic power-saving mode.

Hard disk drive spin-up may take several seconds. A system with many drives may need to stagger spin-up to limit peak power drawn, which is briefly high when an HDD is first started.

Random access Time:-

Solid state drive Typically under 100 µs. As data can be retrieved directly from various locations of the flash memory, access time is usually not a big performance bottleneck.

Hard disk drive Ranges from 2.9 (high end server drive) to 12 ms (laptop HDD) due to the need to move the heads and wait for the data to rotate under the read/write head.

Data transfer rate:-

SSD technology can deliver rather consistent read/write speed, but when lots of individual smaller blocks are accessed, performance is reduced. In consumer products the maximum transfer rate typically ranges from about 100 MB/s to 600 MB/s, depending on the disk.

In Hard disk drive Once the head is positioned, when reading or writing a continuous track, an enterprise HDD can transfer data at about 140 MB/s. In practice transfer speeds are many times lower due to constant seeking, as files are read from various locations or they are fragmented. Data transfer rate depends also upon rotational speed, which can range from 4,200 to 15,000 rpm.

Noise:-

SSDs have no moving parts and therefore are basically silent, although electric noise from the circuits may occur.

HDDs have moving parts (heads, actuator, and spindle motor) and make characteristic sounds of whirring and clicking; noise levels vary between models, but can be significant. Laptop hard disks are relatively quiet.
