For many years there seemed to be a particular trustworthy way for you to store info on a computer – with a hard disk drive (HDD). However, this sort of technology is currently expressing its age – hard drives are loud and sluggish; they can be power–hungry and have a tendency to generate lots of heat throughout intensive procedures.
SSD drives, however, are swift, take in a lesser amount of power and are generally far less hot. They provide a whole new strategy to file access and data storage and are years in advance of HDDs regarding file read/write speed, I/O performance and power effectivity. See how HDDs stand up against the modern SSD drives.
1. Access Time
After the launch of SSD drives, file access rates are now tremendous. As a result of new electronic interfaces found in SSD drives, the normal data file access time has been reduced into a all–time low of 0.1millisecond.
HDD drives even now use the very same basic data file access concept that’s initially developed in the 1950s. Although it has been noticeably advanced since then, it’s slower compared with what SSDs will offer. HDD drives’ data access speed can vary in between 5 and 8 milliseconds.
2. Random I/O Performance
Due to the brand–new revolutionary data file storage strategy embraced by SSDs, they feature speedier file access speeds and speedier random I/O performance.
During PCT Thailand's Website Hosting’s lab tests, all SSDs confirmed their ability to work with a minimum of 6000 IO’s per second.
With a HDD drive, the I/O performance gradually enhances the more you use the drive. However, as soon as it reaches a particular cap, it can’t go swifter. And because of the now–old technology, that I/O limitation is significantly less than what you could receive having an SSD.
HDD are only able to go as much as 400 IO’s per second.
SSD drives are made to have as fewer moving parts as possible. They utilize a similar technology to the one utilized in flash drives and are also much more efficient as compared to common HDD drives.
SSDs come with an average failure rate of 0.5%.
Since we have already noted, HDD drives make use of rotating hard disks. And something that employs a number of moving components for extented periods of time is more prone to failing.
HDD drives’ common rate of failing varies between 2% and 5%.
4. Energy Conservation
SSDs don’t have moving parts and require hardly any cooling down energy. In addition they involve a small amount of electricity to perform – lab tests have revealed they can be powered by a normal AA battery.
In general, SSDs take in between 2 and 5 watts.
HDD drives are renowned for becoming noisy. They require more electricity for cooling down purposes. Within a server which has a multitude of HDDs running all of the time, you’ll need a great deal of fans to ensure they are cooler – this makes them much less energy–efficient than SSD drives.
HDDs use up somewhere between 6 and 15 watts.
5. CPU Power
SSD drives permit better data access rates, which, in return, encourage the processor to perform data calls considerably quicker and then to return to other duties.
The typical I/O hold out for SSD drives is only 1%.
As compared with SSDs, HDDs allow for slower data accessibility speeds. The CPU will have to wait for the HDD to return the demanded file, scheduling its resources for the time being.
The standard I/O delay for HDD drives is around 7%.
6.Input/Output Request Times
It’s about time for some real–world cases. We, at PCT Thailand's Website Hosting, competed a complete system backup on a server using only SSDs for file storage uses. In that procedure, the standard service time for an I/O query kept under 20 ms.
In contrast to SSD drives, HDDs deliver considerably sluggish service rates for input/output demands. Throughout a web server backup, the regular service time for any I/O call can vary somewhere between 400 and 500 ms.
7. Backup Rates
Discussing backups and SSDs – we have noticed an amazing enhancement in the back–up speed as we transferred to SSDs. Currently, a usual web server back–up can take simply 6 hours.
Over time, we’ve made use of mostly HDD drives with our web servers and we’re knowledgeable of their overall performance. With a hosting server designed with HDD drives, a complete hosting server data backup typically takes around 20 to 24 hours.
If you want to at once improve the overall overall performance of your sites and not having to modify any code, an SSD–equipped web hosting service is really a great option.
