Currently, virtually all brand new computing devices include SSD drives as an alternative for HDD drives. You’ll find superlatives on them everywhere in the specialised press – that they’re a lot faster and perform better and that they are really the future of desktop computer and laptop computer production.
On the other hand, how do SSDs fare inside the web hosting community? Could they be dependable enough to substitute the proved HDDs? At Create Free Website, we are going to help you far better be aware of the dissimilarities among an SSD and an HDD and judge the one that best fits you needs.
1. Access Time
Due to a revolutionary new way of disk drive general performance, SSD drives enable for considerably faster data file access rates. Having an SSD, file access times tend to be lower (as little as 0.1 millisecond).
HDD drives continue to use the same general data file access technology that was actually developed in the 1950s. Even though it was noticeably enhanced since that time, it’s slower when compared to what SSDs are offering. HDD drives’ file access speed varies somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Because of the new revolutionary file storage solution shared by SSDs, they have better data access rates and better random I/O performance.
For the duration of our trials, all SSDs confirmed their capability to deal with at least 6000 IO’s per second.
With an HDD drive, the I/O performance progressively improves the more you employ the disk drive. Even so, just after it actually reaches a specific limitation, it can’t get faster. And due to the now–old technology, that I/O limitation is a lot below what you might find with a SSD.
HDD can only go as far as 400 IO’s per second.
The lack of moving components and rotating disks inside SSD drives, as well as the recent advances in electric interface technology have resulted in a considerably better data storage device, having an normal failing rate of 0.5%.
HDD drives implement spinning hard disks for keeping and reading through data – a technology since the 1950s. With disks magnetically suspended in mid–air, spinning at 7200 rpm, the chances of anything failing are considerably increased.
The normal rate of failure of HDD drives ranges between 2% and 5%.
4. Energy Conservation
SSD drives function nearly noiselessly; they don’t create excessive warmth; they don’t call for added chilling alternatives and also consume considerably less energy.
Trials have established that the typical power usage of an SSD drive is somewhere between 2 and 5 watts.
HDD drives are notorious for becoming noisy; they can be prone to getting hot and in case there are several disk drives in a server, you have to have an additional cooling device simply for them.
In general, HDDs take in in between 6 and 15 watts.
5. CPU Power
SSD drives permit swifter data access rates, which will, in return, encourage the processor to accomplish file requests considerably faster and afterwards to go back to other tasks.
The common I/O wait for SSD drives is only 1%.
When you use an HDD, you have to invest additional time looking forward to the outcome of one’s data call. It means that the CPU will remain idle for extra time, waiting for the HDD to react.
The standard I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
Almost all of our brand new web servers now use only SSD drives. Each of our lab tests have demostrated that having an SSD, the average service time for any I/O request although operating a backup stays below 20 ms.
Sticking with the same hosting server, however this time loaded with HDDs, the outcome were different. The common service time for any I/O query fluctuated in between 400 and 500 ms.
7. Backup Rates
Yet another real–life enhancement will be the rate with which the data backup was produced. With SSDs, a server back up today can take less than 6 hours by making use of our web server–designed software.
We employed HDDs exclusively for a couple of years and we have now decent familiarity with just how an HDD works. Generating a backup for a hosting server equipped with HDD drives can take about 20 to 24 hours.
