For years there seemed to be only 1 reliable option to keep information on a personal computer – utilizing a hard disk drive (HDD). Then again, this sort of technology is presently showing its age – hard drives are really loud and sluggish; they can be power–hungry and tend to produce a lot of heat throughout serious procedures.
SSD drives, on the other hand, are fast, consume far less power and are much cooler. They furnish a whole new way of file accessibility and storage and are years ahead of HDDs with regard to file read/write speed, I/O performance and energy capability. See how HDDs stand up up against the modern SSD drives.
1. Access Time
With the arrival of SSD drives, data access rates are now over the top. As a result of new electronic interfaces found in SSD drives, the typical data access time has shrunk towards a record low of 0.1millisecond.
HDD drives even now use the same fundamental data access technology which was actually developed in the 1950s. Though it was considerably enhanced since then, it’s slow compared with what SSDs are offering. HDD drives’ data access rate varies somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Resulting from the unique revolutionary data storage approach shared by SSDs, they offer swifter file access rates and faster random I/O performance.
During our tests, all of the SSDs demonstrated their ability to manage at least 6000 IO’s per second.
With a HDD drive, the I/O performance progressively improves the more you use the drive. Having said that, in the past it actually reaches a particular cap, it can’t get speedier. And because of the now–old technology, that I/O cap is much lower than what you could find with a SSD.
HDD are only able to go as much as 400 IO’s per second.
The absence of moving parts and rotating disks within SSD drives, and also the current advancements in electrical interface technology have led to an extremely safer data file storage device, having an average failure rate of 0.5%.
HDD drives utilize rotating hard disks for keeping and reading through data – a technology dating back to the 1950s. With hard disks magnetically suspended in mid–air, rotating at 7200 rpm, the odds of anything going wrong are usually higher.
The average rate of failing of HDD drives varies amongst 2% and 5%.
4. Energy Conservation
SSD drives operate practically soundlessly; they don’t make surplus warmth; they don’t involve more cooling down alternatives and then consume considerably less electricity.
Lab tests have revealed the average electrical power intake of an SSD drive is somewhere between 2 and 5 watts.
HDD drives can be known for becoming noisy; they can be at risk from overheating and when you have several hard drives within a server, you have to have an additional air conditioning device simply for them.
All together, HDDs take in somewhere between 6 and 15 watts.
5. CPU Power
SSD drives provide for speedier file accessibility rates, which will, subsequently, permit the processor to perform data file requests much faster and then to go back to other responsibilities.
The normal I/O wait for SSD drives is actually 1%.
As compared to SSDs, HDDs allow for slower data file accessibility rates. The CPU will need to lose time waiting for the HDD to send back the requested data file, scheduling its assets for the time being.
The normal I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
The bulk of Number One Hosting Company’s brand–new web servers moved to exclusively SSD drives. Our own lab tests have indicated that by using an SSD, the average service time for any I/O request although operating a backup remains below 20 ms.
During the same trials with the same hosting server, now equipped out with HDDs, overall performance was much slow. During the server backup process, the standard service time for any I/O calls varied between 400 and 500 ms.
7. Backup Rates
Talking about back ups and SSDs – we have witnessed an amazing progress with the back up speed as we turned to SSDs. Currently, a common hosting server data backup takes only 6 hours.
In contrast, with a server with HDD drives, an identical back up usually requires three to four times as long to finish. A full back up of an HDD–powered hosting server usually takes 20 to 24 hours.
To be able to automatically improve the overall general performance of your respective web sites with no need to transform any code, an SSD–operated web hosting solution is really a really good alternative. Take a look at the Linux hosting packages plus the Linux VPS hosting – our solutions feature swift SSD drives and are offered at competitive prices.
