Today, all brand new laptops or computers contain SSD drives in lieu of HDD drives. You’ll discover superlatives about them everywhere in the professional press – that they are faster and function better and that they are the future of home computer and laptop production.
However, how can SSDs fare inside the web hosting world? Could they be dependable enough to substitute the tested HDDs? At Webreg, we are going to help you better understand the differences in between an SSD as well as an HDD and decide the one that most accurately fits you needs.
1. Access Time
Because of a revolutionary new method of disk drive operation, SSD drives permit for considerably quicker data accessibility speeds. Having an SSD, data file accessibility instances are much lower (just 0.1 millisecond).
HDD drives make use of rotating disks for files storage applications. Every time a file is being used, you need to await the appropriate disk to get to the correct position for the laser beam to view the data file you want. This ends in an average access speed of 5 to 8 milliseconds.
2. Random I/O Performance
The random I/O performance is vital for the functionality of any file storage device. We’ve conducted in depth testing and have established an SSD can deal with no less than 6000 IO’s per second.
Hard drives feature reduced data file access rates because of the aging file storage space and access technology they are implementing. And they also illustrate significantly reduced random I/O performance when compared to SSD drives.
Throughout Webreg’s tests, HDD drives dealt with on average 400 IO operations per second.
SSD drives lack just about any moving parts, which means that there’s far less machinery inside them. And the less literally moving components there are, the fewer the possibilities of failing will be.
The average rate of failure of any SSD drive is 0.5%.
With an HDD drive to work, it must rotate a pair of metal disks at more than 7200 rpm, retaining them magnetically stabilized in the air. There is a massive amount of moving parts, motors, magnets as well as other gadgets stuffed in a small space. Consequently it’s no surprise the normal rate of failure of the HDD drive can vary in between 2% and 5%.
4. Energy Conservation
SSD drives are far small compared to HDD drives as well as they don’t possess any moving parts whatsoever. Consequently they don’t generate just as much heat and require less electricity to operate and much less energy for chilling purposes.
SSDs take in somewhere between 2 and 5 watts.
From the moment they have been constructed, HDDs were always quite power–greedy products. Then when you’ve got a server with different HDD drives, this tends to add to the month–to–month electric bill.
Normally, HDDs take in somewhere between 6 and 15 watts.
5. CPU Power
SSD drives support a lot faster file access speeds, which, subsequently, permit the CPU to finish data file queries much faster and afterwards to return to additional jobs.
The typical I/O hold out for SSD drives is only 1%.
HDD drives enable sluggish accessibility rates when compared with SSDs do, resulting in the CPU being forced to hang around, while saving assets for the HDD to find and give back the requested data.
The typical I/O delay for HDD drives is just about 7%.
6.Input/Output Request Times
It is time for a few real–world illustrations. We, at Webreg, produced a complete platform backup with a server using only SSDs for data storage uses. In that operation, the typical service time for an I/O request kept below 20 ms.
Sticking with the same web server, but this time equipped with HDDs, the effects were totally different. The average service time for an I/O query fluctuated somewhere between 400 and 500 ms.
7. Backup Rates
Discussing back–ups and SSDs – we’ve detected a great progress with the back–up rate since we turned to SSDs. Currently, a typical hosting server data backup takes solely 6 hours.
We implemented HDDs mainly for quite a while and we’ve pretty good knowledge of how an HDD performs. Creating a backup for a web server equipped with HDD drives is going to take about 20 to 24 hours.
