For decades there was only one efficient method to store info on your computer – by using a hard drive (HDD). Having said that, this type of technology is presently expressing its age – hard drives are actually loud and sluggish; they are power–ravenous and are likely to generate quite a lot of heat for the duration of serious procedures.

SSD drives, on the contrary, are swift, use up much less energy and are far less hot. They offer a completely new approach to file access and storage and are years ahead of HDDs in terms of file read/write speed, I/O operation and also energy effectivity. Observe how HDDs stand up against the more recent SSD drives.

1. Access Time

SSD drives give a fresh & inventive method to data safe–keeping based on the utilization of electronic interfaces as an alternative to just about any moving components and turning disks. This completely new technology is noticeably faster, making it possible for a 0.1 millisecond data file accessibility time.

HDD drives make use of spinning disks for data storage purposes. Each time a file is being used, you have to await the correct disk to reach the right position for the laser to view the file in question. This leads to an average access speed of 5 to 8 milliseconds.

2. Random I/O Performance

The random I/O performance is vital for the performance of any data file storage device. We have conducted substantial assessments and have confirmed that an SSD can handle no less than 6000 IO’s per second.

Over the same tests, the HDD drives confirmed to be considerably slower, with only 400 IO operations managed per second. Even though this feels like a large amount, if you have an overloaded server that hosts a lot of famous sites, a sluggish harddrive can result in slow–loading websites.

3. Reliability

The absence of moving components and spinning disks inside SSD drives, and also the recent advancements in electronic interface technology have ended in a substantially safer file storage device, with an normal failure rate of 0.5%.

Since we have previously noted, HDD drives use spinning hard disks. And anything that utilizes numerous moving components for prolonged time frames is more prone to failing.

HDD drives’ average rate of failure ranges between 2% and 5%.

4. Energy Conservation

SSD drives are much smaller compared to HDD drives and also they don’t possess any moving elements at all. As a result they don’t generate as much heat and need considerably less energy to function and fewer energy for cooling down purposes.

SSDs consume between 2 and 5 watts.

HDD drives are renowned for becoming noisy. They require far more energy for cooling down applications. Within a hosting server which includes lots of HDDs running regularly, you need a large amount of fans to ensure that they’re cool – this makes them much less energy–economical than SSD drives.

HDDs use up in between 6 and 15 watts.

5. CPU Power

Because of SSD drives’ better I/O functionality, the main web server CPU will be able to work with file requests much faster and conserve time for different functions.

The standard I/O delay for SSD drives is only 1%.

When using an HDD, you have to spend more time watching for the results of one’s data call. Because of this the CPU will remain idle for further time, looking forward to the HDD to reply.

The typical I/O wait for HDD drives is around 7%.

6.Input/Output Request Times

It’s time for a few real–world examples. We competed an entire system backup on a server only using SSDs for data storage reasons. During that operation, the average service time for any I/O demand remained under 20 ms.

In contrast to SSD drives, HDDs feature significantly slower service rates for I/O demands. Throughout a hosting server backup, the common service time for any I/O request ranges between 400 and 500 ms.

7. Backup Rates

A different real–life development is the speed at which the backup is produced. With SSDs, a hosting server back–up now takes only 6 hours using our web server–optimized software.

In the past, we’ve got made use of predominantly HDD drives on our machines and we’re familiar with their general performance. On a hosting server built with HDD drives, a full hosting server data backup normally takes around 20 to 24 hours.

The VPS plans and then the typical shared website hosting plans accounts have SSD drives automatically. Join our apluschoice family, and find out how we can assist you to revitalize your website.
