At present, almost all completely new computing devices are equipped with SSD drives as opposed to HDD drives. You’ll discover superlatives on them all over the specialized press – they are a lot faster and perform better and they are actually the future of home computer and laptop production.
Nonetheless, how can SSDs fare inside the web hosting world? Are they responsible enough to substitute the verified HDDs? At elktis, we are going to assist you much better comprehend the dissimilarities among an SSD as well as an HDD and determine which one is best suited for you needs.
1. Access Time
SSD drives present a completely new & progressive approach to data storage according to the use of electronic interfaces in lieu of just about any moving components and revolving disks. This brand new technology is much quicker, enabling a 0.1 millisecond file access time.
The concept behind HDD drives goes all the way to 1954. And while it’s been considerably refined in recent times, it’s nevertheless no match for the ground breaking concept behind SSD drives. With today’s HDD drives, the very best data access rate you are able to achieve varies between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is really important for the operation of any file storage device. We’ve carried out thorough tests and have determined an SSD can handle no less than 6000 IO’s per second.
With a HDD drive, the I/O performance gradually enhances the more you use the hard drive. Having said that, once it extends to a particular restriction, it can’t go quicker. And due to the now–old concept, that I/O limitation is noticeably less than what you could have having an SSD.
HDD are only able to go as far as 400 IO’s per second.
The lack of moving parts and rotating disks within SSD drives, and the recent improvements in electric interface technology have led to a significantly less risky data storage device, with an typical failing rate of 0.5%.
HDD drives utilize rotating hard disks for storing and reading through info – a concept going back to the 1950s. Along with disks magnetically suspended in the air, rotating at 7200 rpm, the probability of anything failing are much increased.
The normal rate of failing of HDD drives ranges among 2% and 5%.
4. Energy Conservation
SSD drives operate virtually silently; they don’t make excess warmth; they don’t involve extra air conditioning alternatives and take in much less energy.
Tests have indicated that the common electrical power consumption of an SSD drive is somewhere between 2 and 5 watts.
HDD drives are renowned for being loud. They require far more electrical power for cooling purposes. Within a hosting server which has several HDDs running all the time, you will need a large amount of fans to make sure they’re cool – this will make them far less energy–economical than SSD drives.
HDDs consume in between 6 and 15 watts.
5. CPU Power
Because of SSD drives’ better I/O performance, the leading server CPU will be able to process file queries much faster and preserve time for additional operations.
The regular I/O delay for SSD drives is just 1%.
As compared with SSDs, HDDs permit not so quick data file accessibility speeds. The CPU will need to lose time waiting for the HDD to send back the inquired data, scheduling its resources in the meanwhile.
The typical I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
In real life, SSDs carry out as admirably as they performed during the checks. We produced a complete platform back up using one of our production web servers. All through the backup procedure, the normal service time for I/O requests was indeed under 20 ms.
Compared to SSD drives, HDDs provide substantially reduced service rates for I/O queries. In a hosting server backup, the common service time for any I/O request ranges between 400 and 500 ms.
7. Backup Rates
An additional real–life enhancement is the speed at which the data backup has been developed. With SSDs, a web server data backup now takes no more than 6 hours using elktis’s web server–enhanced software.
On the other hand, on a web server with HDD drives, a similar back up usually requires three to four times as long in order to complete. A full back up of an HDD–driven hosting server often takes 20 to 24 hours.
