SSDs vs HDDs
Explore the Pro’s and Con’s of HDD and SSD drives
Today, just about all brand new laptops or computers include SSD drives in place of HDD drives. You can find superlatives about them everywhere in the specialised press – that they’re quicker and function far better and that they are the future of desktop computer and laptop manufacturing.
Nevertheless, how do SSDs perform within the website hosting community? Are they dependable enough to replace the tested HDDs? At Auscfhost, we’ll aid you better understand the dissimilarities between an SSD as well as an HDD and determine the one that best suits you needs.
1. Access Time
Resulting from a radical new method of disk drive performance, SSD drives make it possible for faster file access speeds. Having an SSD, file accessibility instances are far lower (as little as 0.1 millisecond).
The technology driving HDD drives goes all the way to 1954. And while it’s been drastically polished through the years, it’s still can’t stand up to the innovative ideas powering SSD drives. Utilizing today’s HDD drives, the top file access rate you’re able to attain may differ between 5 and 8 milliseconds.
2. Random I/O Performance
Due to the unique radical data storage strategy incorporated by SSDs, they feature swifter data access speeds and speedier random I/O performance.
For the duration of Auscfhost’s tests, all of the SSDs demonstrated their ability to work with at the very least 6000 IO’s per second.
Having an HDD drive, the I/O performance gradually enhances the more you apply the disk drive. Nonetheless, in the past it gets to a certain limitation, it can’t get speedier. And due to the now–old technology, that I/O limit is significantly less than what you could have with an SSD.
HDD can only go so far as 400 IO’s per second.
3. Reliability
SSD drives lack any sort of moving elements, which means there is significantly less machinery in them. And the less literally moving parts you’ll find, the fewer the possibilities of failing can be.
The typical rate of failure of any SSD drive is 0.5%.
Since we already have observed, HDD drives use spinning disks. And anything that takes advantage of a great number of moving elements for prolonged intervals is susceptible to failure.
HDD drives’ normal rate of failing can vary among 2% and 5%.
4. Energy Conservation
SSD drives function practically noiselessly; they don’t create extra warmth; they don’t call for extra cooling down solutions and also use up considerably less power.
Tests have established that the common electric power usage of an SSD drive is somewhere between 2 and 5 watts.
From the second they were constructed, HDDs have been extremely electric power–heavy systems. Then when you’ve got a web server with numerous HDD drives, it will increase the monthly utility bill.
On average, HDDs consume in between 6 and 15 watts.
5. CPU Power
The speedier the data access speed is, the swifter the data file calls can be delt with. This means that the CPU will not have to arrange assets expecting the SSD to reply back.
The normal I/O delay for SSD drives is just 1%.
HDD drives enable slower accessibility rates in comparison to SSDs do, which will result in the CPU being required to hang on, although reserving allocations for the HDD to find and return the inquired data.
The regular I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
In the real world, SSDs function as perfectly as they did in the course of Auscfhost’s trials. We produced an entire system back up using one of the production servers. During the backup process, the common service time for I/O queries was indeed below 20 ms.
Compared to SSD drives, HDDs feature substantially reduced service times for I/O demands. Throughout a server backup, the common service time for any I/O request can vary somewhere between 400 and 500 ms.
7. Backup Rates
One more real–life advancement will be the rate at which the backup has been developed. With SSDs, a web server back–up today can take under 6 hours by making use of Auscfhost’s server–designed software solutions.
Throughout the years, we have employed mainly HDD drives on our web servers and we are familiar with their performance. On a hosting server furnished with HDD drives, an entire server back–up typically takes around 20 to 24 hours.
If you want to easily raise the general performance of one’s sites with no need to modify just about any code, an SSD–driven website hosting service is a good alternative. Take a look at our Linux shared website hosting packages as well as our Linux VPS web hosting – our solutions offer quick SSD drives and can be found at the best prices.
