Today, all of the brand new computer systems have SSD drives as an alternative to HDD drives. You will see superlatives about them everywhere in the specialised press – that they are a lot faster and perform better and that they are the future of desktop computer and laptop computer generation.
On the other hand, how can SSDs perform in the web hosting community? Are they trustworthy enough to replace the tested HDDs? At Web Hosting Priced Right, we are going to make it easier to much better comprehend the dissimilarities between an SSD as well as an HDD and choose which one best fits you needs.
1. Access Time
SSD drives give a fresh & innovative way of data storage in accordance with the usage of electronic interfaces rather than any moving parts and rotating disks. This completely new technology is faster, enabling a 0.1 millisecond data access time.
The technology behind HDD drives goes back to 1954. And even while it has been significantly refined in recent times, it’s still can’t stand up to the inventive concept behind SSD drives. With today’s HDD drives, the highest data access speed you can attain differs somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Resulting from the brand new significant data storage technique incorporated by SSDs, they furnish quicker data access rates and swifter random I/O performance.
All through Web Hosting Priced Right’s tests, all of the SSDs confirmed their capacity to take care of at the least 6000 IO’s per second.
Having an HDD drive, the I/O performance gradually improves the more you apply the drive. Having said that, once it actually reaches a certain restriction, it can’t go quicker. And because of the now–old technology, that I/O limitation is significantly lower than what you could get having an SSD.
HDD can only go so far as 400 IO’s per second.
SSD drives are designed to include as less rotating elements as is possible. They utilize an identical technique to the one employed in flash drives and are also significantly more dependable when compared with standard HDD drives.
SSDs have an typical failing rate of 0.5%.
Since we have already documented, HDD drives rely on rotating hard disks. And anything that works by using many moving elements for extented periods of time is prone to failure.
HDD drives’ typical rate of failing ranges between 2% and 5%.
4. Energy Conservation
SSDs don’t have any moving parts and require almost no cooling down energy. They also demand not much energy to perform – tests have established that they can be powered by a regular AA battery.
As a whole, SSDs consume amongst 2 and 5 watts.
From the moment they have been created, HDDs were always quite electric power–heavy equipment. When you have a server with numerous HDD drives, it will boost the month–to–month power bill.
Typically, HDDs use up between 6 and 15 watts.
5. CPU Power
SSD drives support quicker data file accessibility rates, which will, in return, permit the processor to accomplish data requests much quicker and then to go back to other responsibilities.
The normal I/O hold out for SSD drives is exactly 1%.
By using an HDD, you need to invest more time waiting for the outcomes of your data file request. Consequently the CPU will be idle for extra time, expecting the HDD to react.
The normal I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
It’s about time for a few real–world cases. We competed a full platform backup with a web server using only SSDs for data storage purposes. During that process, the standard service time for any I/O request remained under 20 ms.
With the same web server, however this time equipped with HDDs, the results were completely different. The average service time for an I/O request fluctuated in between 400 and 500 ms.
7. Backup Rates
You can actually check out the real–world great things about having SSD drives every single day. For example, on a hosting server pre–loaded with SSD drives, a full back–up can take just 6 hours.
In contrast, with a web server with HDD drives, a similar back–up could take three to four times as long to complete. An entire back–up of an HDD–equipped server usually takes 20 to 24 hours.
