Solid State Hard Drive Vs Hybrid Hard Drive

Solid State Hard Drive Vs Hybrid Hard Drive

A solid-state drive or a solid-state disk is a secondary storage device that stores persistent and indefatigable data of your computer. It is a non-volatile storage media in the hierarchy of computer storage. SSDs have typically high read speed with lower latency that you have from These are very appropriate and suitable when multiple jobs are running against a single drive. Also, its low energy consumption rate makes it more perfect than its competitors. Compared to the oldest storage media (Hard Disk Drive), solid-state hard drives are more resistant. That’s why now SSDs are very common in PCs.

History and Origin:

SSDs had origin in the 1950s. In the early 1970s, manufacturers implemented it with semiconductors for IBM. But because of its high price, it was rarely used by people at that time. In the 1980s, Toshiba invented Flash-based SSDs. In the late 1980s, Zittel offered a family of SSD products named “RAMDisk.” The capacity of SSD has been improved very much over time. It was 20 Gigabytes has now reached 100 terabytes. And now its price is US$0.10, which was almost US$50,000 per gigabyte at the start.

Firstly, Dataram introduced a bulk core SSD. It was 19 inches in width and 15.75 inches in length, with eight memory boards filled with RAM chips. Magnetic bubble memory is another concept. Magnetic bubble memory chips were more advanced in the term of capacity. And seem to be used by some computers like Grid Compass.

Architecture and Functionality:

Controller and memory are the main components of a Solid-state hard disk. Like host interface, configuration, battery, cache /buffer, many other modules present, but not more significant than these two.  The controller is an embedded processor that performs the functions, including reading and writing caching, block mapping, encryption, and ECC (Error-correcting code). It acts as a bridge between NAND memory and the host computer.

The number of parallel NAND flash chips in the device directly impacts the performance of SSD. Most manufacturers use non-volatile NAND flash-based memory in the construction of SSDs. That is because of its low price compared to others like DRAM-based memory and MRAM-based memory, but slower than DRAM. DRAM uses volatile memory with ultra-fast access (less than 10 microseconds). In this case, if power is lost, the data is copied to RAM and then copied back to the storage when the power is supply.


Whenever we talk about SSDs, a question arises about how SSDs are more appropriate than HHDs. The short answer is that SSDs stores more persistently and deliver read and write with high speed. But the long answer is that there are many features and characteristics of SSDs that make them more attractive than HDDs. As compare to the hard disk drive, SSDs have no moving parts that could break down. Instead of a magnetic read and write approach, Solid-state hard drives use interconnected flash memory chips. Moreover, it uses gate transistors to ensure that the data will not lose even if there is no power supply. Choose best storage for gaming pc from
