Currently, pretty much all completely new computers come with SSD drives in lieu of HDD drives. You will see superlatives on them throughout the specialised press – that they are quicker and conduct better and that they are actually the future of desktop computer and laptop computer manufacturing.
Nonetheless, how do SSDs fare in the hosting environment? Can they be trustworthy enough to replace the established HDDs? At Plus100 Hosting, we will assist you far better be aware of the differences in between an SSD as well as an HDD and decide the one that most accurately fits you needs.
1. Access Time
A result of a radical new way of disk drive performance, SSD drives permit for considerably faster data file access speeds. Having an SSD, data accessibility instances are much lower (just 0.1 millisecond).
HDD drives depend on spinning disks for files storage applications. When a file will be utilized, you have to wait for the appropriate disk to reach the correct position for the laser to access the file in question. This ends in a standard access speed of 5 to 8 milliseconds.
2. Random I/O Performance
Resulting from the brand new revolutionary data storage method shared by SSDs, they furnish better data access speeds and quicker random I/O performance.
For the duration of Plus100 Hosting’s lab tests, all of the SSDs confirmed their capacity to take care of no less than 6000 IO’s per second.
Hard drives feature reduced data file access rates because of the aging file storage and accessibility concept they are by making use of. And they also show considerably sluggish random I/O performance as opposed to SSD drives.
Throughout Plus100 Hosting’s lab tests, HDD drives handled an average of 400 IO operations per second.
SSD drives are created to have as fewer rotating components as possible. They use a comparable concept like the one used in flash drives and are more efficient as opposed to conventional HDD drives.
SSDs come with an common failure rate of 0.5%.
As we have already mentioned, HDD drives rely on rotating disks. And anything that uses a great number of moving components for prolonged time frames is at risk from failure.
HDD drives’ regular rate of failing ranges between 2% and 5%.
4. Energy Conservation
SSDs are lacking moving components and need little or no cooling down power. Additionally, they call for not much energy to function – lab tests have established they can be operated by a regular AA battery.
As a whole, SSDs use up amongst 2 and 5 watts.
From the minute they have been developed, HDDs have invariably been quite electricity–hungry products. Then when you’ve got a server with many types of HDD drives, this can increase the regular monthly electricity bill.
On average, HDDs take in in between 6 and 15 watts.
5. CPU Power
SSD drives support swifter file access speeds, which generally, subsequently, allow the processor to accomplish file requests much quicker and then to go back to other tasks.
The typical I/O wait for SSD drives is barely 1%.
In comparison with SSDs, HDDs enable slower data file access speeds. The CPU will need to wait around for the HDD to return the demanded file, scheduling its allocations in the meantime.
The normal I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
In the real world, SSDs operate as wonderfully as they have during our lab tests. We ran an entire system data backup using one of our own production web servers. Throughout the backup procedure, the common service time for any I/O calls was in fact below 20 ms.
During the identical lab tests using the same server, this time suited out with HDDs, overall performance was substantially reduced. During the server back up process, the normal service time for I/O calls varied between 400 and 500 ms.
7. Backup Rates
Yet another real–life enhancement will be the rate at which the data backup is made. With SSDs, a hosting server backup today will take only 6 hours by making use of our hosting server–enhanced software.
Through the years, we’ve used mostly HDD drives with our web servers and we are familiar with their performance. On a hosting server designed with HDD drives, a full web server back up normally takes about 20 to 24 hours.
