What is a Solid State Drive (SSD)?

A Solid State Drive (SSD) is a server hard disk called stockpiling gadget that holds information in streak memory rather than an attractive based framework like a hard plate drive. By definition, "streak memory is an electronic (strong state) non-unpredictable PC memory capacity medium which can be electrically deleted and reinvented." A strong state drive is characterized by its capacity to store waiter information utilizing the dependable properties of a solid bunch of semiconductors. Since strong state drives don't rely upon moving parts or turning circles, putting away information recovery speed is quicker.

What is a Hard Disk Drive (HDD)?

A Hard Disk Drive (HDD) is a non-unstable, equipment information capacity gadget connected to a PC or waiter. 

A HDD attractively stores, recovers, and results computerized data utilizing a progression of stacked pivoting metallic platters that have been covered with attractive material.

 The pivoting plates are matched with an actuator arm that peruses and composes the computerized information to the server circles.

  • SSD versus HDD Performance Summary
  • SSD    Parameters    HDD
  • 0.1 ms    Access Times    5.5~8.0 ms
  • 6000 io/s    I/O Performance    400 io/s
  • 20 ms    I/O Request Time    400 ~ 500 ms
  • 0.5%    Lifespan (Failure Rate)    2 ~ 5%
  • 2 and 5 Watts    Energy Savings    6 and 15 Watts
  • 1%    CPU Power Consumption    7%
  • 6 Hours    Backup Rates    20~ 24 Hours

Execution and Speed

As far as SSD versus HDD execution, a SSD has information access paces of 40 to 100 microseconds, almost multiple times quicker than a HDD.

Solid state drives keep on overwhelming the hard drive market's development due to the continuous upgrades being made to the strong state drives. Significant makers like SanDisk, Samsung, Sun Microsystems, and Toshiba keep on working on the speed, space, and solidness of SSDs.


In the server hard disk market, SSD offers quicker read and compose times, which speeds up execution by a normal of 95%. This, thus, diminishes page load times, driving engineers to put greater usefulness in online applications. This permits clients to exploit and use more utilitarian sites. SSDs increment the information move rate, which expands the servers' general speed and responsiveness.


Since each capacity block is accessible at a similar speed as each and every other stockpiling block, the entrance rate is dramatically upgraded. This implies that strong state drives throughput is decisively quicker than a HDD.

Limit is consistently a variable while choosing a capacity medium. SSD drives offer the best profit from speculation because of the bigger sizes accessible and valuing choices. Scaling organizations might require seriously facilitating capacity as they develop, going with SSD an optimal decision.


SSDs can peruse consecutive information at up to 550 MBps and compose at up to 520 MBps, though HDDs can deal with successive peruses/composes at 125MBps.

As far as productivity, strong state drives outflank traditional hard drives because of higher dependability, utilization of less power, and quicker read/compose times.


SSDs have no factor to look for time or rotational idleness issues, since strong state drives read and keep in touch with NAND cells, which is generally not quite the same as how HDDs read and compose records. It's a lot quicker, and consumes less power than HDDs.

HDDs require actual mechanical developments to peruse and compose information to the circle, which takes additional time and consumes more power versus SSD.

Life expectancy

SSD life expectancy versus HDD, as far as possible for SSDs, is about 10 years, though HDD drives will endure around three to five years.

Since strong state drives have no dropping parts to wear out or break, they commonly give better execution and a superior life expectancy over HDDs.


Furthermore, SSD gives improved information uprightness and perseverance since they hold information in any event, when shut down. The typical SSD life expectancy can be more limited than 10 years, contingent upon explicit use cases.

Since server HDDs are normally perusing/composing information day in and day out, they will generally require upkeep more regularly. Furthermore, HDDs' disappointment rates go on at roughly 2-5% each year versus SSDs, which just have a disappointment pace of 0.5% each year.


This being said, the SSD has a drawback. There is a limited number of composes accessible, which will influence the possible requirement for a substitution strong state drive to be utilized. A few evaluations place around 3,000 compose cycles normal for every cell before breakdown.

Moreover, a few drives might show up from the plant with corrupted cells, which can cause a dramatically quicker breakdown and cause the drive's initial disappointment.
