Once you have a web site or maybe an web app, pace is really important. The faster your site performs and then the faster your applications operate, the better for you. Given that a website is just a variety of data files that interact with each other, the systems that store and access these data files play a huge role in web site overall performance.
Hard drives, or HDDs, were, until the past few years, the most reliable systems for storing data. Having said that, recently solid–state drives, or SSDs, have already been gathering popularity. Check out our comparability chart to determine whether HDDs or SSDs are better for you.
1. Access Time
Due to a revolutionary new solution to disk drive performance, SSD drives allow for noticeably faster file access speeds. Having an SSD, file accessibility times tend to be lower (as little as 0.1 millisecond).
HDD drives still work with the exact same general data file access technology that was originally created in the 1950s. Even though it has been noticeably upgraded after that, it’s slower when compared to what SSDs are offering. HDD drives’ data file access speed can vary between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is vital for the effectiveness of any data storage device. We’ve carried out thorough testing and have determined an SSD can manage at the very least 6000 IO’s per second.
Throughout the very same tests, the HDD drives demonstrated that they are considerably slower, with 400 IO operations addressed per second. Even though this feels like a large amount, for people with an overloaded server that serves lots of famous web sites, a sluggish hard disk can lead to slow–loading web sites.
SSD drives are designed to have as less moving elements as possible. They use an identical technology like the one utilized in flash drives and are more dependable compared to common HDD drives.
SSDs have an normal failure rate of 0.5%.
HDD drives employ spinning hard disks for saving and browsing info – a technology since the 1950s. And with hard disks magnetically suspended in the air, rotating at 7200 rpm, the prospects of some thing going wrong are generally increased.
The normal rate of failure of HDD drives varies between 2% and 5%.
4. Energy Conservation
SSDs do not have moving parts and require almost no cooling energy. In addition they need very little energy to perform – trials have indicated they can be operated by a normal AA battery.
In general, SSDs use up amongst 2 and 5 watts.
HDD drives are infamous for being loud; they’re at risk of getting hot and when there are several hard drives in a web server, you have to have an extra cooling system used only for them.
All together, HDDs take in in between 6 and 15 watts.
5. CPU Power
The quicker the file access speed is, the swifter the data file requests can be delt with. This means that the CPU will not have to save assets expecting the SSD to answer back.
The average I/O wait for SSD drives is simply 1%.
Compared with SSDs, HDDs allow for not so quick data access speeds. The CPU will be required to wait for the HDD to return the required data file, reserving its assets in the meantime.
The standard I/O delay for HDD drives is around 7%.
6.Input/Output Request Times
The majority of Web-Nic’s new web servers now use just SSD drives. All of our lab tests have demonstrated that utilizing an SSD, the average service time for an I/O request whilst performing a backup continues to be below 20 ms.
Using the same hosting server, yet this time furnished with HDDs, the end results were different. The regular service time for an I/O request changed somewhere between 400 and 500 ms.
7. Backup Rates
You’ll be able to notice the real–world benefits to utilizing SSD drives daily. By way of example, with a hosting server loaded with SSD drives, a complete back–up can take simply 6 hours.
Alternatively, with a hosting server with HDD drives, the same back–up may take three or four times as long to finish. A full back–up of an HDD–equipped hosting server usually takes 20 to 24 hours.
If you want to without delay boost the performance of your respective web sites and not having to change just about any code, an SSD–equipped website hosting solution is a great choice. Have a look at Web-Nic’s Linux website hosting packages packages and also the Linux VPS web hosting packages – our services have fast SSD drives and are available at reasonable prices.
