SSDs vs HDDs
Have a look at Pro’s and Con’s of HDD and SSD drives
Presently, almost all brand new computers come with SSD drives as an alternative to HDD drives. One can find superlatives on them everywhere in the specialized press – that they’re a lot quicker and perform much better and they are the future of desktop computer and laptop manufacturing.
On the other hand, how do SSDs stand up inside the hosting world? Can they be well–performing enough to substitute the successful HDDs? At seogex, we will help you far better comprehend the differences between an SSD and an HDD and decide the one that most accurately fits you needs.
1. Access Time
Due to a radical new method to disk drive performance, SSD drives enable for considerably faster file access rates. Having an SSD, file access times are far lower (only 0.1 millisecond).
The technology driving HDD drives dates all the way to 1954. And even though it’s been significantly enhanced through the years, it’s nonetheless no match for the imaginative technology driving SSD drives. With today’s HDD drives, the top file access rate you are able to reach may differ somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Caused by the new radical file storage method incorporated by SSDs, they furnish better file access rates and better random I/O performance.
During our tests, all SSDs showed their capability to manage at least 6000 IO’s per second.
Hard drives deliver slower file access rates as a result of aging file storage and accessibility technique they are by making use of. And in addition they demonstrate noticeably reduced random I/O performance in comparison to SSD drives.
In the course of seogex’s lab tests, HDD drives addressed an average of 400 IO operations per second.
3. Reliability
The absence of moving parts and rotating disks within SSD drives, as well as the current improvements in electric interface technology have led to a considerably less risky data storage device, with an common failing rate of 0.5%.
Since we have noted, HDD drives make use of spinning disks. And anything that takes advantage of a number of moving elements for prolonged time periods is more prone to failure.
HDD drives’ common rate of failure can vary among 2% and 5%.
4. Energy Conservation
SSDs do not have moving elements and need very little cooling down power. They also demand very little electricity to work – trials have indicated that they can be operated by a standard AA battery.
As a whole, SSDs use up somewhere between 2 and 5 watts.
HDD drives are famous for being loud. They require far more energy for air conditioning reasons. With a web server containing a lot of different HDDs running consistently, you will need a great number of fans to keep them cooler – this may cause them much less energy–economical than SSD drives.
HDDs take in between 6 and 15 watts.
5. CPU Power
Thanks to SSD drives’ higher I/O performance, the key server CPU can easily process data queries more rapidly and save time for different functions.
The common I/O delay for SSD drives is only 1%.
HDD drives accommodate reduced accessibility speeds compared to SSDs do, resulting for the CPU having to hold out, while saving resources for the HDD to locate and return the requested data file.
The common I/O delay for HDD drives is around 7%.
6.Input/Output Request Times
The vast majority of seogex’s brand–new web servers now use just SSD drives. Our own tests have revealed that by using an SSD, the average service time for an I/O request whilst building a backup stays below 20 ms.
Sticking with the same web server, yet this time furnished with HDDs, the outcome were totally different. The normal service time for any I/O call fluctuated between 400 and 500 ms.
7. Backup Rates
Referring to back–ups and SSDs – we have found a significant progress with the backup speed since we switched to SSDs. Now, a regular web server backup requires only 6 hours.
On the other hand, on a web server with HDD drives, the same back up might take 3 to 4 times as long in order to complete. An entire back–up of an HDD–powered web server may take 20 to 24 hours.
The VPS servers and then our standard cloud website hosting plans accounts offer SSD drives by default. Be a part of our family here, at seogex, to see how we can help you revitalize your site.
