SSDs vs HDDs
Discover which storage space service is better for your cloud hosting account
For many years there was just one single reliable option to store information on a computer – by using a disk drive (HDD). Nonetheless, this kind of technology is presently expressing its age – hard drives are actually loud and sluggish; they are power–hungry and are likely to generate lots of heat in the course of intensive operations.
SSD drives, on the other hand, are extremely fast, take in significantly less power and are much cooler. They furnish a whole new way of file access and data storage and are years ahead of HDDs in terms of file read/write speed, I/O performance as well as power capability. Observe how HDDs stand up up against the modern SSD drives.
1. Access Time
Resulting from a revolutionary new approach to disk drive general performance, SSD drives enable for faster data file accessibility speeds. Having an SSD, data accessibility times tend to be lower (only 0.1 millisecond).
HDD drives even now makes use of the exact same general data access technique which was initially developed in the 1950s. Even though it was vastly upgraded ever since, it’s slower when compared with what SSDs are providing. HDD drives’ data access rate can vary between 5 and 8 milliseconds.
2. Random I/O Performance
Caused by the completely new significant file storage technique shared by SSDs, they give you swifter data access rates and speedier random I/O performance.
In the course of Don Webhosting’s trials, all SSDs revealed their capacity to deal with no less than 6000 IO’s per second.
Hard drives feature slower data access speeds because of the aging file storage space and accessibility technology they are using. And in addition they show substantially slower random I/O performance when compared to SSD drives.
During Don Webhosting’s trials, HDD drives dealt with an average of 400 IO operations per second.
3. Reliability
SSD drives do not have virtually any moving parts, which means there is a lesser amount of machinery included. And the less physically moving elements you will find, the lower the probability of failing can be.
The regular rate of failing of an SSD drive is 0.5%.
As we have already mentioned, HDD drives rely upon spinning disks. And something that employs plenty of moving parts for extented time periods is susceptible to failing.
HDD drives’ common rate of failing can vary between 2% and 5%.
4. Energy Conservation
SSD drives are usually smaller compared to HDD drives as well as they do not have any kind of moving elements at all. Because of this they don’t produce as much heat and need less power to work and much less power for chilling reasons.
SSDs use up between 2 and 5 watts.
HDD drives can be known for getting noisy; they’re liable to getting too hot and when you have several disk drives in a single hosting server, you have to have an extra cooling system exclusively for them.
In general, HDDs take in in between 6 and 15 watts.
5. CPU Power
The faster the file accessibility rate is, the quicker the data demands are going to be adressed. Because of this the CPU do not need to save resources looking forward to the SSD to answer back.
The regular I/O wait for SSD drives is 1%.
HDD drives support sluggish accessibility rates when compared with SSDs do, resulting in the CPU being forced to hold out, while scheduling resources for your HDD to uncover and give back the inquired file.
The normal I/O wait for HDD drives is just about 7%.
6.Input/Output Request Times
Almost all of Don Webhosting’s brand new machines moved to only SSD drives. Each of our tests have revealed that having an SSD, the normal service time for an I/O request although doing a backup remains under 20 ms.
During the exact same trials using the same hosting server, this time installed out utilizing HDDs, performance was much reduced. Throughout the server backup process, the average service time for I/O calls ranged between 400 and 500 ms.
7. Backup Rates
You can easily feel the real–world benefits to using SSD drives on a daily basis. For example, on a web server loaded with SSD drives, a complete backup is going to take only 6 hours.
Over the years, we have made use of predominantly HDD drives on our machines and we are familiar with their general performance. On a web server furnished with HDD drives, an entire web server back up usually takes about 20 to 24 hours.
With Don Webhosting, you will get SSD–powered website hosting services at competitive prices. The cloud web hosting plans and also the VPS service can include SSD drives by default. Apply for an web hosting account here and see the way your sites can become much better promptly.
