SSDs vs HDDs
Examine the Pro’s and Con’s of HDD and SSD drives
For those who have a website or an app, speed is extremely important. The speedier your web site works and the swifter your applications perform, the better for everyone. Considering that a website is a group of files that talk with one another, the devices that store and access these files play a vital role in web site overall performance.
Hard disk drives, or HDDs, were, right until recent years, the more effective devices for keeping data. Nonetheless, in recent years solid–state drives, or SSDs, are already becoming more popular. Have a look at our comparison chart to find out if HDDs or SSDs are more appropriate for you.
1. Access Time
Resulting from a radical new solution to disk drive operation, SSD drives permit for much quicker data accessibility speeds. Having an SSD, data file accessibility times are far lower (under 0.1 millisecond).
The concept driving HDD drives times back to 1954. And even while it has been considerably processed in recent times, it’s nevertheless can’t stand up to the ingenious technology powering SSD drives. Having today’s HDD drives, the top file access speed it is possible to reach may differ between 5 and 8 milliseconds.
2. Random I/O Performance
Resulting from the unique radical data storage method adopted by SSDs, they offer faster data access speeds and quicker random I/O performance.
For the duration of Host Composer’s lab tests, all of the SSDs confirmed their ability to take care of no less than 6000 IO’s per second.
Throughout the same trials, the HDD drives demonstrated to be considerably slower, with 400 IO operations maintained per second. Even though this might appear to be a good deal, if you have a busy server that contains a lot of popular web sites, a slow hard disk drive may result in slow–loading websites.
3. Reliability
The absence of moving elements and rotating disks in SSD drives, and also the current advances in electronic interface technology have resulted in a significantly less risky data storage device, with an average failing rate of 0.5%.
Since we already have mentioned, HDD drives use rotating hard disks. And anything that makes use of a great number of moving elements for prolonged time frames is prone to failure.
HDD drives’ normal rate of failing can vary between 2% and 5%.
4. Energy Conservation
SSD drives are far smaller than HDD drives as well as they don’t possess any moving parts at all. Because of this they don’t produce so much heat and require considerably less energy to operate and less energy for cooling down purposes.
SSDs take in between 2 and 5 watts.
HDD drives are renowned for getting noisy. They need extra electricity for cooling purposes. On a hosting server which has lots of HDDs running continuously, you will need a great deal of fans to make sure they’re cool – this makes them much less energy–effective than SSD drives.
HDDs consume in between 6 and 15 watts.
5. CPU Power
Thanks to SSD drives’ better I/O efficiency, the main web server CPU will be able to process file requests a lot quicker and save time for other procedures.
The normal I/O delay for SSD drives is 1%.
HDD drives allow for reduced accessibility speeds compared with SSDs do, which will result for the CPU being forced to hold out, whilst arranging resources for the HDD to discover and return the inquired file.
The common I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
It’s time for several real–world illustrations. We, at Host Composer, ran a full platform backup on a web server only using SSDs for data storage purposes. In that procedure, the typical service time for any I/O call kept beneath 20 ms.
Sticking with the same web server, yet this time equipped with HDDs, the results were totally different. The regular service time for any I/O query changed between 400 and 500 ms.
7. Backup Rates
You can actually notice the real–world benefits of having SSD drives on a daily basis. For instance, with a hosting server furnished with SSD drives, a complete back up can take only 6 hours.
In contrast, on a server with HDD drives, an identical backup might take three to four times as long in order to complete. A full back–up of an HDD–equipped hosting server may take 20 to 24 hours.
Our Linux shared website hosting accounts feature SSD drives automatically. Join our family here, at Host Composer, to see how we can assist you to transform your site.
