SSD, which is otherwise known as “Solid State Drive”, is a data-storage medium, just like a flash drive or compact disk. Presently, ‘hard-disks’ or ‘hard-drives’ are highly in use. This is probably because of its high storage capacity and faster data transfer. Solid State Drives could be considered as an emulation of hard disks. This Solid State Drive uses either a static-RAM (SRAM) or a dynamic-RAM (DRAM), and hence SSDs are otherwise termed as RAM-drive. More precisely, it is made of NAND flash non-volatile memory or DRAM volatile memory.
Solid State Drives make use of the chips and semiconductors, instead of the electron tubes. This concept has been acquired from ‘Solid State Physics’, and hence the name. Additionally, the term Solid State also aids in differentiating SSDs from other conventional electromechanical storage devices.
Talking about its advantages over the electromechanical devices or rather the magnetic disks, it is essential to mention that these Solid State Devices are very robust and not fragile due to the absence of any moving parts. This again prevents the sound or rather noise triggered by other electromechanical devices. SSD consume comparatively less power due to the absence of motors or other moving parts. The high speed access is another catch of the Solid state drives, since it has no spinning procedures as that in a conventional drive. Besides, it is very reliable data storage medium and very low latency time. In the conventional mechanical drives, occasionally there might be mechanical failures, which have made Solid State devices even more reliable and hence advantageous. It can used internal to the computer, just like a hark disk. This is probably why, Solid State Drives are considered as an emulation of Hard Drives. It has a considerable range of operating temperatures when compared to hard disks. Drive failures occur either while erasing the cells or while writing. This obviously means that there is no failure during ‘read’ operation. So, what’s the catch? Well, failure during ‘read’ operation means that the data has been lost forever. But, a failure during ‘write’ or ‘erase’ operation will result in the data being written in another location or that the data would not have been erased respectively.
