Presently, virtually all new computer systems come with SSD drives instead of HDD drives. You can see superlatives on them everywhere in the specialized press – they are a lot quicker and conduct much better and they are actually the future of home pc and laptop computer production.
However, how do SSDs fare in the web hosting world? Can they be responsible enough to replace the proven HDDs? At Spdy VPS, we will assist you to much better see the dissimilarities among an SSD and an HDD and choose which one is best suited for you needs.
1. Access Time
Due to a radical new method to disk drive performance, SSD drives allow for much faster file access speeds. With an SSD, data access times are much lower (as low as 0.1 millisecond).
HDD drives depend on rotating disks for data storage applications. Every time a file will be used, you need to wait for the appropriate disk to get to the right position for the laser to view the data file in question. This ends in a standard access rate of 5 to 8 milliseconds.
2. Random I/O Performance
Because of the unique significant file storage solution embraced by SSDs, they have faster file access speeds and quicker random I/O performance.
Throughout Spdy VPS’s trials, all of the SSDs confirmed their ability to work with at least 6000 IO’s per second.
Hard drives deliver slower data file access speeds because of the aging file storage and access technique they’re implementing. In addition, they display much sluggish random I/O performance as compared to SSD drives.
Throughout our tests, HDD drives maintained typically 400 IO operations per second.
SSD drives are built to have as fewer rotating parts as is practical. They utilize an identical technology like the one used in flash drives and are also much more efficient when compared to traditional HDD drives.
SSDs come with an normal failure rate of 0.5%.
For the HDD drive to operate, it has to spin 2 metallic disks at more than 7200 rpm, having them magnetically stabilized in the air. They have a lots of moving elements, motors, magnets and also other devices packed in a small place. Consequently it’s obvious why the regular rate of failure associated with an HDD drive can vary among 2% and 5%.
4. Energy Conservation
SSD drives are far small compared to HDD drives and also they lack virtually any moving parts at all. It means that they don’t generate so much heat and need a lot less energy to function and fewer energy for cooling down purposes.
SSDs use up somewhere between 2 and 5 watts.
HDD drives can be known for becoming loud; they are at risk from heating up and whenever there are several hard drives in one web server, you will need one more a / c unit just for them.
In general, HDDs consume between 6 and 15 watts.
5. CPU Power
As a result of SSD drives’ higher I/O efficiency, the main web server CPU will be able to work with data file queries more rapidly and conserve time for different functions.
The average I/O wait for SSD drives is just 1%.
When using an HDD, you will need to dedicate additional time awaiting the outcomes of one’s data file call. As a result the CPU will remain idle for much more time, awaiting the HDD to reply.
The regular I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
The vast majority of our completely new machines moved to simply SSD drives. Each of our tests have established that with an SSD, the typical service time for any I/O request although running a backup stays under 20 ms.
With the same server, however, this time built with HDDs, the results were different. The common service time for any I/O request changed in between 400 and 500 ms.
7. Backup Rates
You can experience the real–world added benefits of utilizing SSD drives every single day. For example, on a hosting server loaded with SSD drives, a full back up will take only 6 hours.
In the past, we’ve got used primarily HDD drives on our servers and we are knowledgeable of their performance. With a web server equipped with HDD drives, a full hosting server data backup normally takes around 20 to 24 hours.
