SSDs vs HDDs
Do a comparison of the two industry–leading data storage devices
These days, pretty much all new computing devices are equipped with SSD drives as an alternative to HDD drives. You can see superlatives to them all over the specialized press – that they’re quicker and function much better and they are actually the future of home computer and laptop computer production.
Nevertheless, how do SSDs perform in the web hosting world? Are they efficient enough to substitute the tested HDDs? At EtherVPS, we’ll aid you much better be aware of the dissimilarities in between an SSD and an HDD and judge which one most accurately fits you needs.
1. Access Time
A result of a revolutionary new solution to disk drive performance, SSD drives enable for faster data access speeds. Having an SSD, data accessibility times are far lower (just 0.1 millisecond).
HDD drives continue to take advantage of the very same basic file access concept that was originally developed in the 1950s. Though it was significantly enhanced after that, it’s sluggish compared with what SSDs are providing. HDD drives’ data access speed varies somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is vital for the efficiency of a data file storage device. We have run in depth exams and have established that an SSD can deal with at least 6000 IO’s per second.
With a HDD drive, the I/O performance progressively improves the more you use the drive. However, once it extends to a specific restriction, it can’t get swifter. And because of the now–old concept, that I/O limitation is much less than what you could get with a SSD.
HDD can only go as much as 400 IO’s per second.
3. Reliability
SSD drives are made to have as less rotating components as is feasible. They use an identical technology like the one used in flash drives and are significantly more efficient in comparison to standard HDD drives.
SSDs provide an average failing rate of 0.5%.
As we have documented, HDD drives use rotating disks. And something that works by using many moving components for extented intervals is liable to failure.
HDD drives’ normal rate of failing can vary somewhere between 2% and 5%.
4. Energy Conservation
SSD drives operate almost noiselessly; they don’t generate excess heat; they don’t require more air conditioning options and then consume a lot less power.
Lab tests have demostrated that the typical electrical power utilization of an SSD drive is amongst 2 and 5 watts.
HDD drives are renowned for getting noisy. They need extra electric power for chilling purposes. On a hosting server containing a multitude of HDDs running continuously, you need a great deal of fans to ensure they are kept cool – this will make them far less energy–efficient than SSD drives.
HDDs consume between 6 and 15 watts.
5. CPU Power
The speedier the data file access rate is, the sooner the data file requests will be delt with. Because of this the CPU won’t have to hold assets expecting the SSD to reply back.
The normal I/O wait for SSD drives is just 1%.
When using an HDD, you have to spend extra time watching for the outcome of one’s data ask. It means that the CPU will continue to be idle for more time, looking forward to the HDD to reply.
The typical I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
The vast majority of EtherVPS’s brand new servers are now using simply SSD drives. Each of our tests have established that by using an SSD, the normal service time for any I/O request although building a backup continues to be below 20 ms.
In comparison with SSD drives, HDDs feature much slower service rates for I/O requests. In a hosting server backup, the common service time for any I/O request varies between 400 and 500 ms.
7. Backup Rates
Yet another real–life improvement will be the speed at which the backup has been created. With SSDs, a web server backup now takes no more than 6 hours using EtherVPS’s server–enhanced software.
Over time, we’ve utilized mostly HDD drives with our servers and we’re well aware of their overall performance. On a server designed with HDD drives, a full hosting server back–up may take about 20 to 24 hours.
Should you want to without delay enhance the performance of your sites with no need to adjust any kind of code, an SSD–operated hosting service is a really good choice. Check out our Linux web hosting packages as well as our VPS hosting service – these hosting solutions feature extremely fast SSD drives and are offered at the best prices.
