SSDs vs HDDs
Compare and contrast the 2 industry–leading data storage space devices
Currently, pretty much all completely new computing devices are equipped with SSD drives as an alternative to HDD drives. You can find superlatives on them all over the specialised press – they are quicker and perform better and that they are the future of home pc and laptop manufacturing.
Even so, how can SSDs fare within the web hosting world? Can they be reliable enough to substitute the proven HDDs? At Self-Server.net, we will assist you better understand the differences between an SSD and an HDD and decide which one best suits you needs.
1. Access Time
After the arrival of SSD drives, data accessibility speeds are now tremendous. On account of the brand new electronic interfaces employed in SSD drives, the average data file access time has shrunk to a record low of 0.1millisecond.
HDD drives still makes use of the very same general file access technique that’s actually developed in the 1950s. Even though it has been much enhanced consequently, it’s sluggish in comparison with what SSDs are offering. HDD drives’ data file access speed varies between 5 and 8 milliseconds.
2. Random I/O Performance
As a result of the brand new significant data storage solution embraced by SSDs, they give you quicker data access speeds and faster random I/O performance.
In the course of Self-Server.net’s lab tests, all of the SSDs showed their capacity to manage at least 6000 IO’s per second.
With an HDD drive, the I/O performance progressively raises the more you employ the disk drive. Even so, as soon as it actually reaches a specific limit, it can’t go faster. And due to the now–old technology, that I/O restriction is much lower than what you might get having an SSD.
HDD are only able to go as much as 400 IO’s per second.
3. Reliability
SSD drives are meant to include as fewer rotating parts as is feasible. They utilize an identical concept to the one found in flash drives and are also much more trustworthy as compared to traditional HDD drives.
SSDs offer an normal failure rate of 0.5%.
HDD drives work with rotating hard disks for storing and browsing files – a technology going back to the 1950s. Along with disks magnetically suspended in the air, spinning at 7200 rpm, the likelihood of something failing are considerably increased.
The standard rate of failure of HDD drives varies between 2% and 5%.
4. Energy Conservation
SSD drives are considerably small compared to HDD drives and also they lack virtually any moving elements whatsoever. As a result they don’t make as much heat and require much less energy to function and fewer energy for chilling reasons.
SSDs consume between 2 and 5 watts.
HDD drives are famous for getting noisy. They need a lot more power for cooling down reasons. On a hosting server which has a number of HDDs running continuously, you will need a lot of fans to ensure they are kept cool – this makes them far less energy–efficient than SSD drives.
HDDs take in between 6 and 15 watts.
5. CPU Power
SSD drives provide for quicker file access rates, which generally, in return, enable the processor to perform data file calls much quicker and then to go back to different jobs.
The regular I/O hold out for SSD drives is just 1%.
In comparison with SSDs, HDDs permit not so quick file accessibility rates. The CPU will have to wait around for the HDD to send back the requested data, scheduling its assets in the meanwhile.
The standard I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
It’s about time for some real–world examples. We, at Self-Server.net, ran an entire system backup on a server using only SSDs for data storage purposes. In that procedure, the typical service time for an I/O demand kept under 20 ms.
Throughout the same trials with the exact same web server, this time installed out with HDDs, overall performance was significantly slower. During the web server back–up procedure, the standard service time for any I/O calls fluctuated between 400 and 500 ms.
7. Backup Rates
You can notice the real–world added benefits of utilizing SSD drives on a regular basis. As an example, on a hosting server built with SSD drives, a full backup will take simply 6 hours.
Over the years, we have got made use of mostly HDD drives with our web servers and we are well aware of their general performance. With a hosting server equipped with HDD drives, an entire hosting server back up typically takes around 20 to 24 hours.
The cloud hosting plans accounts offer SSD drives automatically. Be a part of our family here, at Self-Server.net, to check out the way we can assist you to help your site.
