Nowadays, all completely new laptops or computers contain SSD drives as an alternative for HDD drives. You will find superlatives about them all around the specialised press – that they are faster and conduct far better and that they are actually the future of desktop computer and laptop computer generation.
However, how can SSDs stand up within the hosting community? Can they be dependable enough to substitute the verified HDDs? At WebDog Web Hosting, we’ll aid you far better comprehend the differences between an SSD and an HDD and choose which one best fits you needs.
1. Access Time
SSD drives offer a brand–new & ingenious solution to data storage using the usage of electronic interfaces as an alternative to any sort of moving parts and turning disks. This innovative technology is way quicker, enabling a 0.1 millisecond data file accessibility time.
HDD drives still use the exact same general file access technique which was initially developed in the 1950s. Even though it was significantly enhanced ever since, it’s slow as compared with what SSDs are offering to you. HDD drives’ data access speed ranges somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
As a result of the completely new significant data file storage technique adopted by SSDs, they supply swifter data access speeds and speedier random I/O performance.
In the course of our trials, all SSDs confirmed their capability to work with at the very least 6000 IO’s per second.
With an HDD drive, the I/O performance steadily improves the more you use the drive. Nevertheless, once it actually reaches a specific limit, it can’t proceed quicker. And because of the now–old technology, that I/O cap is a lot less than what you could have having an SSD.
HDD are only able to go as much as 400 IO’s per second.
SSD drives are designed to have as less moving parts as is possible. They use a similar technique like the one utilized in flash drives and are also significantly more trustworthy in comparison with common HDD drives.
SSDs offer an average failure rate of 0.5%.
For an HDD drive to work, it needs to spin 2 metallic hard disks at more than 7200 rpm, holding them magnetically stabilized in the air. There is a number of moving components, motors, magnets and also other tools packed in a tiny location. Hence it’s no wonder that the regular rate of failing associated with an HDD drive ranges somewhere between 2% and 5%.
4. Energy Conservation
SSD drives operate virtually soundlessly; they don’t create excessive heat; they don’t demand more chilling options and also use up significantly less power.
Tests have shown the typical power usage of an SSD drive is amongst 2 and 5 watts.
HDD drives are renowned for getting noisy. They need more energy for air conditioning reasons. With a server that has several HDDs running all of the time, you will need a lot of fans to ensure that they’re cooler – this will make them much less energy–efficient than SSD drives.
HDDs consume between 6 and 15 watts.
5. CPU Power
SSD drives permit faster data access rates, which generally, in turn, allow the processor to finish file queries considerably faster and then to return to additional duties.
The average I/O wait for SSD drives is just 1%.
As compared to SSDs, HDDs permit slower file access rates. The CPU is going to await the HDD to send back the requested data file, saving its resources in the meantime.
The regular I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
The majority of our completely new web servers are now using only SSD drives. Our personal lab tests have revealed that by using an SSD, the typical service time for any I/O request whilst performing a backup remains under 20 ms.
In contrast to SSD drives, HDDs feature noticeably reduced service times for I/O queries. Throughout a hosting server backup, the common service time for an I/O call ranges between 400 and 500 ms.
7. Backup Rates
A different real–life development will be the rate at which the back–up is made. With SSDs, a hosting server data backup currently can take under 6 hours implementing WebDog Web Hosting’s hosting server–enhanced software.
We worked with HDDs exclusively for a few years and we’ve excellent expertise in precisely how an HDD runs. Generating a backup for a web server designed with HDD drives will take about 20 to 24 hours.
