For those who have a website or maybe an web application, speed is critical. The swifter your website works and then the faster your web applications operate, the better for you. Considering that a website is only an offering of data files that interact with one another, the devices that store and access these files play a crucial role in website performance.
Hard disks, or HDDs, have been, right up until recent years, the more effective devices for keeping information. Having said that, recently solid–state drives, or SSDs, have been rising in popularity. Take a look at our evaluation chart to view whether HDDs or SSDs are more suitable for you.
1. Access Time
Resulting from a radical new method of disk drive performance, SSD drives make it possible for much quicker data file access speeds. With an SSD, data file access times tend to be lower (as small as 0.1 millisecond).
The technology driving HDD drives times all the way to 1954. And while it’s been substantially processed as time passes, it’s still no match for the ground breaking technology behind SSD drives. Having today’s HDD drives, the highest data file access speed you are able to attain can vary somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
On account of the new revolutionary file storage approach embraced by SSDs, they furnish swifter file access rates and better random I/O performance.
Throughout our trials, all of the SSDs showed their capability to deal with at least 6000 IO’s per second.
Hard drives deliver slower data file access speeds due to aging file storage space and accessibility concept they are making use of. And they also demonstrate substantially sluggish random I/O performance as compared with SSD drives.
In the course of IQLAB’s lab tests, HDD drives addressed an average of 400 IO operations per second.
The lack of moving elements and rotating disks inside SSD drives, and also the recent advances in electrical interface technology have ended in an extremely less risky file storage device, with an common failing rate of 0.5%.
HDD drives utilize spinning disks for storing and browsing files – a technology since the 1950s. And with hard disks magnetically suspended in mid–air, rotating at 7200 rpm, the possibilities of anything failing are generally bigger.
The common rate of failing of HDD drives varies among 2% and 5%.
4. Energy Conservation
SSDs don’t have any moving elements and require almost no chilling power. In addition they involve very little energy to work – lab tests have established that they’ll be powered by a normal AA battery.
In general, SSDs use up between 2 and 5 watts.
HDD drives can be known for being noisy; they are liable to getting hot and in case there are several hard drives in a server, you must have an extra cooling system simply for them.
In general, HDDs take in somewhere between 6 and 15 watts.
5. CPU Power
Because of SSD drives’ greater I/O functionality, the leading web server CPU can easily process data requests more quickly and save time for additional procedures.
The average I/O wait for SSD drives is 1%.
Compared to SSDs, HDDs permit slower data file accessibility speeds. The CPU will need to lose time waiting for the HDD to send back the inquired data file, saving its assets in the meanwhile.
The average I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
It’s time for several real–world examples. We produced a complete platform backup on a server only using SSDs for data storage purposes. In that procedure, the standard service time for an I/O request remained under 20 ms.
Compared with SSD drives, HDDs offer considerably sluggish service times for input/output queries. Throughout a web server backup, the standard service time for an I/O request ranges between 400 and 500 ms.
7. Backup Rates
Discussing back–ups and SSDs – we’ve detected an amazing enhancement in the back up speed since we moved to SSDs. Now, a usual server backup will take merely 6 hours.
Throughout the years, we’ve used principally HDD drives with our servers and we are familiar with their performance. With a server equipped with HDD drives, a full web server back up often takes about 20 to 24 hours.
