For many years there seemed to be only one dependable way for you to store information on a pc – having a hard drive (HDD). Then again, this kind of technology is actually showing its age – hard disks are really noisy and sluggish; they’re power–hungry and tend to produce a lot of heat throughout serious operations.

SSD drives, in contrast, are swift, consume a lesser amount of power and they are much cooler. They furnish a new solution to file accessibility and data storage and are years ahead of HDDs when considering file read/write speed, I/O operation and also power effectivity. Discover how HDDs fare up against the more recent SSD drives.

1. Access Time

A result of a revolutionary new approach to disk drive operation, SSD drives permit for considerably quicker data access rates. With an SSD, data file accessibility times are far lower (just 0.1 millisecond).

HDD drives continue to take advantage of the exact same fundamental file access concept that’s initially created in the 1950s. Even though it was much enhanced after that, it’s slower in comparison to what SSDs are offering. HDD drives’ data file access speed ranges somewhere between 5 and 8 milliseconds.

2. Random I/O Performance

The random I/O performance is crucial for the effectiveness of a data storage device. We’ve conducted thorough assessments and have established an SSD can handle no less than 6000 IO’s per second.

Hard drives provide slower data file access rates due to the aging file storage and accessibility technique they’re using. And they also display significantly slower random I/O performance compared with SSD drives.

During’s lab tests, HDD drives maintained around 400 IO operations per second.

3. Reliability

The lack of moving components and rotating disks in SSD drives, as well as the latest developments in electrical interface technology have resulted in a considerably less risky data storage device, with an average failure rate of 0.5%.

Since we have noted, HDD drives rely on spinning hard disks. And something that employs plenty of moving parts for prolonged intervals is prone to failing.

HDD drives’ normal rate of failing can vary somewhere between 2% and 5%.

4. Energy Conservation

SSD drives are usually smaller than HDD drives as well as they don’t possess any kind of moving elements at all. Consequently they don’t make just as much heat and need less power to operate and less energy for cooling reasons.

SSDs use up somewhere between 2 and 5 watts.

HDD drives are infamous for getting loud; they’re prone to getting hot and if there are several disk drives inside a server, you must have a different air conditioning device simply for them.

In general, HDDs take in between 6 and 15 watts.

5. CPU Power

As a result of SSD drives’ higher I/O efficiency, the key hosting server CPU can easily process file queries much faster and save time for different functions.

The regular I/O wait for SSD drives is 1%.

By using an HDD, you will need to dedicate extra time waiting around for the results of your data query. Because of this the CPU will remain idle for further time, waiting for the HDD to reply.

The regular I/O delay for HDD drives is around 7%.

6.Input/Output Request Times

It’s time for some real–world instances. We competed an entire platform backup on a web server using only SSDs for data storage purposes. During that operation, the standard service time for an I/O query remained under 20 ms.

Sticking with the same web server, however, this time furnished with HDDs, the outcome were completely different. The regular service time for an I/O call changed in between 400 and 500 ms.

7. Backup Rates

One more real–life advancement is the speed at which the backup has been developed. With SSDs, a server back–up today requires less than 6 hours by making use of our web server–enhanced software solutions.

Over the years, we’ve employed largely HDD drives with our servers and we are well aware of their overall performance. On a server pre–loaded with HDD drives, an entire hosting server data backup usually takes around 20 to 24 hours.

If you want to automatically enhance the effectiveness of one’s web sites and never having to transform any code, an SSD–driven hosting solution is a good solution.
