Today, almost all completely new computers contain SSD drives as an alternative to HDD drives. You can find superlatives about them throughout the professional press – they are quicker and operate better and they are actually the future of desktop computer and laptop generation.
Nonetheless, how can SSDs perform inside the website hosting environment? Can they be reliable enough to substitute the proven HDDs? At compurus.com, we will help you far better be aware of the distinctions between an SSD as well as an HDD and choose which one most closely fits you needs.
1. Access Time
Resulting from a revolutionary new method of disk drive functionality, SSD drives allow for much faster file accessibility rates. Having an SSD, data file accessibility instances are much lower (under 0.1 millisecond).
HDD drives depend on spinning disks for data storage purposes. Every time a file is being utilized, you will need to wait for the appropriate disk to get to the right place for the laser to reach the data file you want. This leads to a common access speed of 5 to 8 milliseconds.
2. Random I/O Performance
Due to the completely new revolutionary data storage method embraced by SSDs, they have swifter data access rates and faster random I/O performance.
During our lab tests, all SSDs showed their ability to handle at the least 6000 IO’s per second.
Throughout the very same trials, the HDD drives demonstrated to be considerably slower, with 400 IO operations handled per second. While this might appear to be a large number, when you have a busy web server that serves a lot of well known sites, a slow hard disk can lead to slow–loading websites.
SSD drives don’t have just about any rotating components, which means that there is a lesser amount of machinery inside them. And the fewer literally moving components you’ll find, the fewer the possibilities of failure can be.
The common rate of failure of any SSD drive is 0.5%.
Since we have already mentioned, HDD drives rely upon spinning disks. And anything that works by using lots of moving parts for prolonged amounts of time is prone to failing.
HDD drives’ normal rate of failing can vary somewhere between 2% and 5%.
4. Energy Conservation
SSDs don’t have moving parts and need hardly any cooling energy. They also call for not much power to function – tests have revealed that they can be operated by a standard AA battery.
As a whole, SSDs consume amongst 2 and 5 watts.
From the time they were designed, HDDs were always really electricity–heavy products. And when you’ve got a hosting server with a bunch of HDD drives, this will boost the month to month electric bill.
Typically, HDDs consume in between 6 and 15 watts.
5. CPU Power
The quicker the file access rate is, the sooner the data file queries will be treated. As a result the CPU won’t have to reserve resources waiting around for the SSD to respond back.
The regular I/O delay for SSD drives is 1%.
HDD drives allow for sluggish accessibility rates when compared with SSDs do, which will result for the CPU being forced to hang on, whilst reserving assets for the HDD to find and give back the requested data file.
The common I/O delay for HDD drives is around 7%.
6.Input/Output Request Times
It’s about time for some real–world examples. We competed an entire system backup on a hosting server only using SSDs for file storage purposes. In that procedure, the common service time for an I/O demand stayed below 20 ms.
All through the same trials using the same server, now equipped out with HDDs, efficiency was considerably slow. All through the server back up procedure, the common service time for I/O calls fluctuated between 400 and 500 ms.
7. Backup Rates
Speaking about back–ups and SSDs – we’ve witnessed a fantastic development in the back–up speed as we turned to SSDs. Currently, a usual server data backup can take only 6 hours.
Over the years, we have utilized mainly HDD drives on our machines and we’re well aware of their functionality. On a web server designed with HDD drives, a complete hosting server data backup will take around 20 to 24 hours.
The Linux hosting accounts have SSD drives by default. Be part of our family here, at compurus.com, and find out how we can assist you to transform your web site.
