For decades there seemed to be only one efficient method to keep info on a computer – using a hard disk drive (HDD). Nevertheless, this kind of technology is actually expressing its age – hard drives are noisy and slow; they can be power–ravenous and tend to create quite a lot of warmth during intense procedures.
SSD drives, in contrast, are really fast, use up far less energy and are generally far less hot. They provide a brand new solution to file accessibility and data storage and are years ahead of HDDs in terms of file read/write speed, I/O effectiveness as well as energy effectivity. Observe how HDDs fare up against the modern SSD drives.
1. Access Time
With the introduction of SSD drives, file accessibility speeds are now tremendous. As a result of new electronic interfaces employed in SSD drives, the typical data access time has been reduced into a record low of 0.1millisecond.
The concept behind HDD drives goes all the way back to 1954. Even though it’s been substantially polished throughout the years, it’s nevertheless no match for the innovative technology behind SSD drives. Using today’s HDD drives, the highest file access speed you can actually reach varies between 5 and 8 milliseconds.
2. Random I/O Performance
With thanks to the very same radical strategy that enables for speedier access times, you can also appreciate improved I/O efficiency with SSD drives. They will carry out two times as many operations during a specific time compared to an HDD drive.
An SSD can deal with at the very least 6000 IO’s per second.
Over the same lab tests, the HDD drives demonstrated to be significantly slower, with only 400 IO operations handled per second. While this might appear to be a great number, for those who have a busy web server that serves a great deal of popular websites, a slow hard disk drive can lead to slow–loading websites.
SSD drives are built to include as fewer rotating components as feasible. They use a similar concept like the one utilized in flash drives and are generally more efficient compared with common HDD drives.
SSDs offer an normal failing rate of 0.5%.
Since we have mentioned, HDD drives depend on spinning hard disks. And anything that employs plenty of moving components for extented amounts of time is at risk from failure.
HDD drives’ normal rate of failing ranges among 2% and 5%.
4. Energy Conservation
SSDs are lacking moving parts and require very little cooling power. In addition they require very little electricity to work – tests have revealed they can be operated by a regular AA battery.
As a whole, SSDs take in between 2 and 5 watts.
HDD drives are famous for becoming noisy. They require further electrical power for cooling purposes. Within a server that has a multitude of HDDs running regularly, you will need a good deal of fans to make sure they’re cool – this makes them a lot less energy–effective than SSD drives.
HDDs consume in between 6 and 15 watts.
5. CPU Power
SSD drives enable quicker data file access speeds, which generally, in return, enable the CPU to finish data requests much faster and afterwards to return to other tasks.
The common I/O wait for SSD drives is simply 1%.
When compared with SSDs, HDDs enable reduced data accessibility rates. The CPU must await the HDD to send back the inquired data file, scheduling its allocations in the meantime.
The regular I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
The bulk of Mediajem Hosting UK’s brand–new servers are now using solely SSD drives. All of our lab tests have indicated that having an SSD, the common service time for any I/O request whilst running a backup stays below 20 ms.
With the exact same server, but this time built with HDDs, the results were very different. The average service time for any I/O call changed somewhere between 400 and 500 ms.
7. Backup Rates
You are able to notice the real–world great things about utilizing SSD drives day–to–day. For instance, on a server loaded with SSD drives, a complete back up is going to take merely 6 hours.
Through the years, we’ve used predominantly HDD drives with our servers and we’re knowledgeable of their performance. On a server pre–loaded with HDD drives, an entire web server back up usually takes about 20 to 24 hours.
To be able to instantly add to the performance of your respective sites with no need to adjust just about any code, an SSD–operated web hosting solution is really a good solution.
