SSDs vs HDDs
Learn which data storage device is better for your website hosting account
Presently, pretty much all completely new personal computers come with SSD drives in lieu of HDD drives. You can see superlatives to them all around the specialised press – that they’re a lot quicker and perform much better and they are actually the future of home computer and laptop computer generation.
Then again, how can SSDs perform within the web hosting environment? Can they be reliable enough to substitute the proved HDDs? At Owl Hosting, we are going to aid you far better be aware of the distinctions in between an SSD as well as an HDD and choose the one that best fits you needs.
1. Access Time
Resulting from a revolutionary new solution to disk drive performance, SSD drives make it possible for much faster data file access speeds. Having an SSD, file access instances are far lower (under 0.1 millisecond).
The technology behind HDD drives dates all the way back to 1954. And although it has been noticeably processed in recent times, it’s nevertheless can’t stand up to the revolutionary technology powering SSD drives. With today’s HDD drives, the highest data file access rate it is possible to attain can vary between 5 and 8 milliseconds.
2. Random I/O Performance
Due to the exact same revolutionary technique that permits for better access times, it is possible to experience greater I/O performance with SSD drives. They’re able to perform double the operations throughout a specific time as compared to an HDD drive.
An SSD can manage a minimum of 6000 IO’s per second.
Hard drives present slower data access speeds due to older file storage and accessibility technique they’re employing. And in addition they demonstrate considerably reduced random I/O performance compared with SSD drives.
In the course of Owl Hosting’s lab tests, HDD drives maintained typically 400 IO operations per second.
3. Reliability
SSD drives do not have virtually any rotating components, which means there’s far less machinery in them. And the less physically moving components you can find, the lower the chances of failure will be.
The normal rate of failure of an SSD drive is 0.5%.
HDD drives implement rotating hard disks for keeping and reading data – a concept since the 1950s. And with hard disks magnetically hanging in the air, spinning at 7200 rpm, the possibilities of one thing failing are generally increased.
The regular rate of failing of HDD drives varies amongst 2% and 5%.
4. Energy Conservation
SSD drives function nearly silently; they don’t create extra heat; they don’t require extra cooling down solutions and take in way less energy.
Tests have indicated the average electric power intake of an SSD drive is amongst 2 and 5 watts.
HDD drives can be notorious for becoming noisy; they’re prone to getting too hot and if there are several hard drives inside a server, you have to have one more a / c unit exclusively for them.
All together, HDDs take in between 6 and 15 watts.
5. CPU Power
SSD drives provide for quicker data file accessibility rates, which generally, consequently, allow the CPU to accomplish data file queries much faster and to go back to other tasks.
The common I/O hold out for SSD drives is just 1%.
As compared with SSDs, HDDs enable reduced file access rates. The CPU will need to wait for the HDD to return the requested file, scheduling its resources in the meantime.
The standard I/O delay for HDD drives is about 7%.
6.Input/Output Request Times
It is time for several real–world illustrations. We ran a complete platform backup on a server using only SSDs for file storage reasons. During that procedure, the standard service time for any I/O call stayed below 20 ms.
With the exact same server, however this time loaded with HDDs, the end results were different. The standard service time for an I/O request changed somewhere between 400 and 500 ms.
7. Backup Rates
An additional real–life improvement will be the speed with which the data backup has been made. With SSDs, a hosting server backup today requires only 6 hours by using Owl Hosting’s web server–enhanced software.
Alternatively, with a server with HDD drives, the same back up normally takes 3 to 4 times as long to finish. A complete back up of any HDD–powered hosting server typically takes 20 to 24 hours.
Our web hosting plans accounts include SSD drives by default. Join our family here, at Owl Hosting, to see how we can assist you enhance your site.
