SSD is the acronym of Solid State Drives. SSDs are the new bee in world of Storage technology which promises great potential/future. SSD is not a stand alone memory element as in conventional storage devices, it contain its own CPU, a battery and a memory bus board. SSD is a NAND based non-volatile memory device which support plug and play feature. It didn’t contain any moving mechanism for fetching and storing data on the memory but it employs piles of semiconductor memory chips. In this article I will let you know about the SSD “What does it offer?” and whether you replace your HDD or not with the SSD.
Features of SSD:
- SSD employs NAND memory architecture similar to the flash memory. As NAND based memory devices offer greater chip density and reduces total size of the memory chip. We also have NAND based memory system but it needs more wiring thus require more chip area and offer less chip density as compared to the NOR memory architecture.
- SSD employs semiconductor chips to store data where as in conventional HDD deploys magnetic platters to store data. In HDD magnetic platters are kept on a spindle on which a mechanical arm with bunch of READ/WRITE heads keep on moving for facilitating data migration between the CPU, memory and other peripherals.
- SSD are less noisy as compared to the HDD as it involves movements of mechanical parts for data transmission between the CPU and other peripheral devices. You have heard sometime the clicking sound suddenly when you start copying or moving large amount of data on your laptop. In case of SSD a processor/CPU is embedded on the chip which uses data buses to facilitate data migration between the storage devices. So produce almost zero noise.
- As SSD employs semiconductor chips for storage so draws very less power and are light in weight as compared to the HDD.
- SSD offers more speed as compare to the HDD for data read and write operation which results in faster execution of data transmission between the computer and the peripherals. SSD offers a transmission rate of 500 – 600 MBs data per second where as HDD offers a transmission rate of 50 – 150 MBs of data per second. Even the computer setup which deploys SDD take less time (almost 22 secs) for booting process and get your computer startup screen.
Drawback of SSD:
- In this world money pays a great role in influencing life of all of us. SDD are much expensive than HDD. For getting 1 GB of SSD you have to spend 1.75 $ from a good branded company where as you have to spend only 0.15 $ for getting the 1 GB of HDD. So if are not bother about the price then SSD is a handy option for you.
- But you must lookout for this fact before switching your HDD. It is very important to know that SDD renders only fixed number of Program/erase cycles thus seems to be not so good in log term use. This issue arises due to the fact that SDD use semiconductor memory which employs grid of transistor arranged in row column synchronized with each other. Some charge is left after data operation in transistor connected in the grid mounted on the memory chips which result in spike in resistance of Gate terminal of the concerned transistor thus after sometime data write operation become useless affects the SSD write ability badly. Many of the OEM use techniques like wear-leveling or came up with some of the new ideas like they had use the combination of HDD and SSD. Many of the world renowned companies are using SDD as RAM and HDD as external storage which results in greater speed of data migration.
Thus in my opinion SSD is a lot better option for who desire speed at the trade off cost. If you still have any problem then you can use the online technical support services provided by some of the well renowned companies. They also provide reliable computer maintenance tools for enhancing the speed and performance of computer.
SSD based memory system contain its own CPU, a battery and a memory bus board. SSD is a NAND based non-volatile memory device which support plug and play feature. SSD are little bit expensive but offers tremendous speed.
