SSDs vs HDDs
Compare the two industry–leading data storage devices
At present, pretty much all new laptops or computers are equipped with SSD drives in place of HDD drives. You’ll discover superlatives about them all over the professional press – that they’re quicker and conduct better and that they are actually the future of home pc and laptop computer manufacturing.
Even so, how do SSDs fare in the hosting world? Can they be responsible enough to replace the established HDDs? At YourDomainBoss.Com, we will assist you to far better see the differences in between an SSD as well as an HDD and choose the one that best fits you needs.
1. Access Time
SSD drives have a brand–new & ingenious way of data storage according to the use of electronic interfaces in place of any kind of moving parts and revolving disks. This innovative technology is much quicker, enabling a 0.1 millisecond file accessibility time.
The technology behind HDD drives dates back to 1954. And while it has been substantially processed as time passes, it’s still no match for the inventive concept driving SSD drives. Through today’s HDD drives, the highest data file access speed you can actually attain varies between 5 and 8 milliseconds.
2. Random I/O Performance
Due to the new revolutionary data storage strategy shared by SSDs, they provide a lot quicker file access speeds and faster random I/O performance.
In the course of YourDomainBoss.Com’s lab tests, all of the SSDs confirmed their capability to work with at least 6000 IO’s per second.
With an HDD drive, the I/O performance gradually improves the more you apply the disk drive. Nonetheless, in the past it reaches a particular cap, it can’t get faster. And because of the now–old technology, that I/O limit is a lot lower than what you can find with an SSD.
HDD can only go so far as 400 IO’s per second.
3. Reliability
The absence of moving components and rotating disks inside SSD drives, and the recent advances in electric interface technology have generated a much better data file storage device, with a common failure rate of 0.5%.
To have an HDD drive to work, it has to rotate a pair of metal hard disks at more than 7200 rpm, holding them magnetically stabilized in mid–air. They have a lots of moving components, motors, magnets and also other gadgets stuffed in a tiny space. Consequently it’s no surprise that the regular rate of failure of the HDD drive varies among 2% and 5%.
4. Energy Conservation
SSD drives are usually small compared to HDD drives as well as they don’t have just about any moving elements whatsoever. As a result they don’t create just as much heat and require significantly less electricity to work and much less energy for cooling reasons.
SSDs consume between 2 and 5 watts.
HDD drives can be notorious for becoming loud; they are at risk of overheating and if there are several disk drives inside a web server, you will need one more cooling system exclusively for them.
All together, HDDs take in between 6 and 15 watts.
5. CPU Power
The speedier the data file accessibility rate is, the quicker the data file queries will be treated. It means that the CPU won’t have to reserve assets looking forward to the SSD to reply back.
The standard I/O wait for SSD drives is just 1%.
When you use an HDD, you will have to dedicate time watching for the outcome of one’s data ask. As a result the CPU will stay idle for much more time, waiting around for the HDD to respond.
The normal I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
It’s time for some real–world illustrations. We produced an entire system backup on a web server using only SSDs for file storage uses. During that process, the regular service time for any I/O call stayed under 20 ms.
Compared with SSD drives, HDDs deliver much reduced service times for input/output demands. In a server backup, the regular service time for an I/O request can vary between 400 and 500 ms.
7. Backup Rates
You can easily experience the real–world benefits to having SSD drives daily. As an example, with a server equipped with SSD drives, a complete back–up will take only 6 hours.
We made use of HDDs mainly for quite a while and we’ve pretty good knowledge of how an HDD works. Creating a backup for a web server equipped with HDD drives can take around 20 to 24 hours.
