Presently, all of the completely new computing devices have SSD drives in lieu of HDD drives. You will see superlatives on them everywhere in the professional press – that they are quicker and operate better and that they are the future of home computer and laptop manufacturing.
Then again, how can SSDs stand up inside the hosting environment? Are they responsible enough to replace the established HDDs? At Google Web Scan, we’ll help you far better see the differences between an SSD and an HDD and decide which one best suits you needs.
1. Access Time
Resulting from a radical new solution to disk drive functionality, SSD drives enable for much faster data access speeds. With an SSD, data file access times are much lower (only 0.1 millisecond).
HDD drives still utilize the exact same basic file access concept which was initially developed in the 1950s. Even though it has been noticeably advanced since then, it’s slow when compared to what SSDs are providing. HDD drives’ data file access speed varies in between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is vital for the efficiency of any data storage device. We have run thorough testing and have identified that an SSD can manage at the very least 6000 IO’s per second.
Hard drives deliver slower data access rates because of the older file storage and accessibility concept they are employing. And in addition they display noticeably slower random I/O performance compared with SSD drives.
For the duration of our trials, HDD drives addressed typically 400 IO operations per second.
SSD drives lack virtually any rotating elements, meaning there is a lesser amount of machinery in them. And the less literally moving components there are, the lower the probability of failing will be.
The common rate of failure of an SSD drive is 0.5%.
Since we have already mentioned, HDD drives rely on spinning hard disks. And anything that makes use of lots of moving elements for lengthy periods of time is more likely to failing.
HDD drives’ typical rate of failure varies somewhere between 2% and 5%.
4. Energy Conservation
SSDs don’t have moving components and require minimal chilling power. They also require very little electricity to operate – tests have indicated that they’ll be operated by a common AA battery.
As a whole, SSDs use up between 2 and 5 watts.
From the moment they were developed, HDDs have been quite energy–greedy devices. So when you have a web server with a couple of HDD drives, this will increase the regular monthly utility bill.
Typically, HDDs take in between 6 and 15 watts.
5. CPU Power
SSD drives allow for faster file accessibility speeds, which generally, in turn, allow the processor to finish data file requests much faster and after that to return to other responsibilities.
The typical I/O wait for SSD drives is 1%.
In comparison to SSDs, HDDs enable reduced data accessibility speeds. The CPU will have to lose time waiting for the HDD to send back the requested data file, saving its resources in the meantime.
The standard I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
It is time for several real–world cases. We produced a detailed system backup with a hosting server using only SSDs for file storage uses. In that process, the normal service time for any I/O request stayed under 20 ms.
Compared with SSD drives, HDDs feature much slower service times for I/O queries. During a server backup, the common service time for any I/O query ranges between 400 and 500 ms.
7. Backup Rates
Referring to backups and SSDs – we have detected an effective enhancement in the back up speed since we turned to SSDs. Currently, a common server back–up can take merely 6 hours.
Throughout the years, we have got employed predominantly HDD drives with our web servers and we are well aware of their effectiveness. With a server built with HDD drives, a full hosting server backup may take about 20 to 24 hours.
