Reinvent Enterprise Storage with SSD
It is awe-inspiring to see how Solid State Drives (SSD) have come a long way and have clearly outperformed the traditional Hard Disk Drives (HDD) for permanent data storage. It is a silver bullet for data latency problems, especially in high density enterprise data centers. What are the reasons for its success? To figure out, let us compare SSD with traditional HDD.
HDDs are still consumed largely in the market and will live perennially for obvious benefits of lower cost per storage capacity and higher capacity per disk. However it’s underlying technology architecture resulting in slower performance positions it behind SSD.
HDD technology relies on spinning platters and read/write heads to magnetically store or retrieve data. These mechanical parts are the bottleneck that limits faster read/write operation and consumes more power .
Also, because of spinning platters, HDDs are more vulnerable to physical damage and wear out. Usually, HDD is the first thing to break in a computer.
The underlying storage technology in SSD is flash memory based on transistors, not magnetic media. Thanks to the fact that SSDs have no moving parts. In contrast to HDDs, SSDs are not fragile and handles shock and vibration much better than a rotating disk drive. They are heat tolerant and consumes lesser power than HDDs.
Surprisingly, SSD comes in traditional storage disk form factors such as 3.5-inch or 2.5-inch. Therefore, replacement can be done easily, as SSDs can be fitted into the same slots as identical form factored HDDs.
More importantly, SSDs have faster read/write, lower latency, and supports more IOPS (Input Output Operations Per Second) compared to traditional HDDs.
While talking about storage performance, IOPS is considered as an important metric. As the name implies, it measures how many input output operations are completed per second. Usually, a typical HDD can do about 100-200 IOPS when reading 4K sized data, whereas a SSD can do 10,000 to 100,000 IOPS. Simply to say, the slowest SSD has 50x higher random IOPS than the fastest HDD.
At the end
With its unmovable technique and great performance, SSD promises faster data storage with a higher throughput at low price. It has been reinventing the enterprise storage platform with its robust performance.
