At present, just about all new computers include SSD drives as an alternative to HDD drives. You’ll find superlatives to them all around the professional press – that they’re quicker and conduct better and they are actually the future of home computer and laptop computer production.
Having said that, how do SSDs fare in the website hosting environment? Are they efficient enough to substitute the tested HDDs? At Bulls Host, we are going to help you far better comprehend the dissimilarities between an SSD as well as an HDD and decide the one that most closely fits you needs.
1. Access Time
Resulting from a radical new approach to disk drive performance, SSD drives allow for much quicker data file accessibility speeds. With an SSD, data file access instances are much lower (as little as 0.1 millisecond).
HDD drives continue to take advantage of the very same fundamental data access technology which was originally developed in the 1950s. Despite the fact that it was considerably advanced since then, it’s slower as compared to what SSDs are providing. HDD drives’ file access rate ranges between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is crucial for the overall performance of a file storage device. We’ve run detailed trials and have identified that an SSD can handle a minimum of 6000 IO’s per second.
Having an HDD drive, the I/O performance gradually enhances the more you apply the hard drive. Nevertheless, in the past it reaches a certain cap, it can’t get faster. And due to the now–old concept, that I/O limitation is much lower than what you could receive with an SSD.
HDD can only go as far as 400 IO’s per second.
The lack of moving elements and spinning disks in SSD drives, and also the current developments in electronic interface technology have led to a significantly less risky data storage device, having an average failure rate of 0.5%.
Since we have observed, HDD drives make use of spinning disks. And something that takes advantage of a large number of moving elements for lengthy intervals is vulnerable to failing.
HDD drives’ typical rate of failure varies somewhere between 2% and 5%.
4. Energy Conservation
SSD drives are much small compared to HDD drives as well as they do not have any moving components whatsoever. This means that they don’t produce so much heat and need a lot less electricity to work and less power for chilling purposes.
SSDs consume amongst 2 and 5 watts.
HDD drives can be well known for becoming noisy; they are liable to getting hot and whenever you have several hard drives in a single web server, you’ll want an additional a / c system only for them.
In general, HDDs consume somewhere between 6 and 15 watts.
5. CPU Power
SSD drives allow for swifter data file accessibility speeds, that, subsequently, permit the processor to complete file calls much faster and then to return to other duties.
The regular I/O hold out for SSD drives is exactly 1%.
When compared with SSDs, HDDs enable reduced data access rates. The CPU must lose time waiting for the HDD to come back the requested data file, saving its allocations in the meanwhile.
The common I/O wait for HDD drives is around 7%.
6.Input/Output Request Times
In real life, SSDs function as admirably as they did during our trials. We ran a full system back up on one of the production machines. Throughout the backup process, the regular service time for I/O calls was basically under 20 ms.
With the same web server, however this time furnished with HDDs, the effects were different. The common service time for any I/O request fluctuated somewhere between 400 and 500 ms.
7. Backup Rates
Yet another real–life improvement is the speed at which the back–up has been developed. With SSDs, a hosting server back up currently will take only 6 hours by using our web server–designed software solutions.
We implemented HDDs mainly for lots of years and we have got pretty good expertise in exactly how an HDD works. Backing up a hosting server equipped with HDD drives can take around 20 to 24 hours.
