Currently, virtually all completely new computer systems contain SSD drives as an alternative to HDD drives. You will see superlatives on them everywhere in the specialised press – they are a lot quicker and operate far better and that they are the future of home pc and laptop generation.
Then again, how can SSDs stand up in the hosting environment? Can they be responsible enough to replace the tested HDDs? At 212 Hosting Professional, we are going to aid you much better see the distinctions between an SSD as well as an HDD and decide which one best fits you needs.
1. Access Time
SSD drives present a completely new & revolutionary approach to data safe–keeping using the utilization of electronic interfaces instead of just about any moving parts and turning disks. This completely new technology is much quicker, enabling a 0.1 millisecond data access time.
The technology driving HDD drives goes all the way back to 1954. And although it’s been considerably enhanced in recent times, it’s nevertheless no match for the ground breaking ideas powering SSD drives. Having today’s HDD drives, the top file access rate you are able to reach can vary in between 5 and 8 milliseconds.
2. Random I/O Performance
Because of the unique radical data file storage method embraced by SSDs, they have a lot quicker data access rates and better random I/O performance.
All through our trials, all of the SSDs revealed their capability to handle at least 6000 IO’s per second.
Hard drives deliver slower file access speeds because of the older file storage and access technology they are employing. In addition, they display noticeably reduced random I/O performance in comparison to SSD drives.
In the course of 212 Hosting Professional’s lab tests, HDD drives addressed on average 400 IO operations per second.
SSD drives are designed to include as less rotating elements as is feasible. They use a comparable technology like the one employed in flash drives and are more dependable when compared to regular HDD drives.
SSDs provide an average failing rate of 0.5%.
To have an HDD drive to work, it has to spin a pair of metallic disks at more than 7200 rpm, retaining them magnetically stabilized in the air. There is a whole lot of moving components, motors, magnets and other devices packed in a small space. Therefore it’s no surprise that the regular rate of failure of the HDD drive varies somewhere between 2% and 5%.
4. Energy Conservation
SSD drives function virtually noiselessly; they don’t generate excessive heat; they don’t involve additional air conditioning solutions and also take in considerably less energy.
Tests have established that the average electric power usage of an SSD drive is between 2 and 5 watts.
As soon as they have been built, HDDs were always quite electricity–heavy devices. So when you’ve got a web server with different HDD drives, this can raise the month–to–month electricity bill.
Typically, HDDs use up somewhere between 6 and 15 watts.
5. CPU Power
Thanks to SSD drives’ better I/O performance, the key web server CPU can work with data demands more quickly and preserve time for other functions.
The average I/O wait for SSD drives is just 1%.
HDD drives permit slower access speeds in comparison with SSDs do, which will result in the CPU needing to delay, while arranging allocations for your HDD to locate and give back the inquired data.
The common I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
In real life, SSDs carry out as perfectly as they did during our lab tests. We produced a complete system back–up using one of the production machines. During the backup procedure, the normal service time for any I/O demands was below 20 ms.
In comparison with SSD drives, HDDs deliver significantly reduced service rates for I/O requests. Throughout a web server backup, the regular service time for an I/O call ranges between 400 and 500 ms.
7. Backup Rates
Another real–life improvement is the rate at which the backup was produced. With SSDs, a web server back–up now can take no more than 6 hours using 212 Hosting Professional’s web server–optimized software.
Over time, we’ve made use of predominantly HDD drives on our web servers and we’re well aware of their overall performance. On a web server built with HDD drives, a full server back–up typically takes about 20 to 24 hours.
