Nowadays, all completely new computing devices have SSD drives as an alternative for HDD drives. You will find superlatives to them all over the specialized press – that they’re a lot quicker and conduct far better and that they are the future of desktop computer and laptop production.
Then again, how do SSDs perform within the web hosting environment? Can they be responsible enough to replace the proven HDDs? At ITDA Group, we’ll make it easier to far better comprehend the distinctions among an SSD as well as an HDD and determine which one is best suited for you needs.
1. Access Time
With the release of SSD drives, file access rates are now over the top. As a result of brand–new electronic interfaces found in SSD drives, the normal data access time has been reduced to a all–time low of 0.1millisecond.
The technology driving HDD drives goes all the way to 1954. Even though it’s been substantially processed throughout the years, it’s nevertheless no match for the revolutionary technology behind SSD drives. Having today’s HDD drives, the best data file access rate you can actually achieve differs in between 5 and 8 milliseconds.
2. Random I/O Performance
Resulting from the completely new radical data storage solution adopted by SSDs, they have swifter data access rates and better random I/O performance.
Throughout our tests, all SSDs showed their capability to deal with a minimum of 6000 IO’s per second.
Hard drives present reduced data file access rates due to the older file storage and access technology they are using. Additionally they illustrate considerably sluggish random I/O performance as compared with SSD drives.
In the course of our tests, HDD drives dealt with around 400 IO operations per second.
The lack of moving parts and rotating disks within SSD drives, and the current developments in electrical interface technology have generated a much safer data storage device, with an common failure rate of 0.5%.
As we already have noted, HDD drives rely upon rotating disks. And something that utilizes a large number of moving parts for extended intervals is at risk from failing.
HDD drives’ regular rate of failure ranges somewhere between 2% and 5%.
4. Energy Conservation
SSD drives are usually smaller than HDD drives and also they don’t have just about any moving elements at all. This means that they don’t produce so much heat and need a lot less energy to function and less energy for chilling reasons.
SSDs consume between 2 and 5 watts.
From the moment they were designed, HDDs have invariably been extremely electrical power–hungry devices. And when you have a web server with many types of HDD drives, this tends to 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 easily work with file calls much faster and preserve time for different functions.
The standard I/O delay for SSD drives is 1%.
When compared to SSDs, HDDs allow for reduced file accessibility rates. The CPU is going to lose time waiting for the HDD to send back the demanded data file, saving its assets in the meantime.
The typical I/O wait for HDD drives is around 7%.
6.Input/Output Request Times
It’s time for several real–world illustrations. We, at ITDA Group, produced a full platform backup on a server only using SSDs for file storage uses. During that operation, the common service time for an I/O call stayed beneath 20 ms.
Weighed against SSD drives, HDDs offer much reduced service rates for I/O requests. Throughout a server backup, the normal service time for an I/O call varies between 400 and 500 ms.
7. Backup Rates
A different real–life development will be the rate with which the data backup is produced. With SSDs, a server back–up currently can take only 6 hours implementing our hosting server–designed software.
Throughout the years, we’ve got worked with mainly HDD drives with our servers and we are familiar with their performance. With a server furnished with HDD drives, a complete server back up usually takes around 20 to 24 hours.
