SSDs vs. HDDs

Learn which storage service is better for your cloud hosting account

For years there was one efficient way to store info on a laptop – utilizing a hard drive (HDD). However, this type of technology is currently displaying its age – hard drives are really loud and slow; they can be power–hungry and have a tendency to generate a great deal of heat for the duration of serious procedures.

SSD drives, however, are extremely fast, take in much less energy and they are much cooler. They provide a completely new method of file access and storage and are years in advance of HDDs regarding file read/write speed, I/O performance and also energy efficacy. Find out how HDDs fare up against the more recent SSD drives.

1. Access Time

Resulting from a revolutionary new approach to disk drive performance, SSD drives make it possible for considerably faster data accessibility rates. With an SSD, data file access instances tend to be lower (as low as 0.1 millisecond).

The concept powering HDD drives dates all the way to 1954. And even though it’s been drastically polished in recent times, it’s nonetheless can’t stand up to the ingenious technology powering SSD drives. Utilizing today’s HDD drives, the best data access rate you are able to attain can vary between 5 and 8 milliseconds.

2. Random I/O Performance

Caused by the new radical data storage solution shared by SSDs, they feature quicker data access rates and better random I/O performance. During WnD Solutions’s trials, all of the SSDs confirmed their capacity to deal with at the least 6000 IO’s per second.
Hard drives offer slower data access rates because of the older file storage and access concept they’re implementing. In addition, they illustrate considerably reduced random I/O performance as compared with SSD drives. For the duration of WnD Solutions’s trials, HDD drives dealt with around 400 IO operations per second.

3. Reliability

The absence of moving parts and spinning disks inside SSD drives, as well as the recent advances in electrical interface technology have led to a much safer file storage device, having an normal failing rate of 0.5%.
For an HDD drive to operate, it must spin a couple metal hard disks at over 7200 rpm, retaining them magnetically stabilized in mid–air. There is a good deal of moving elements, motors, magnets along with other gadgets packed in a small location. Therefore it’s no wonder that the average rate of failing of the HDD drive ranges between 2% and 5%.

4. Energy Conservation

SSD drives are far smaller compared to HDD drives and also they lack just about any moving parts at all. Because of this they don’t make as much heat and require less electricity to work and less power for cooling down purposes. SSDs take in amongst 2 and 5 watts.
From the time they have been designed, HDDs have always been quite electric power–heavy devices. Then when you’ve got a hosting server with multiple HDD drives, this will add to the month–to–month electricity bill. Typically, HDDs take in between 6 and 15 watts.

5. CPU Power

As a result of SSD drives’ higher I/O effectiveness, the key server CPU can process data file queries much faster and save time for additional operations. The common I/O wait for SSD drives is only 1%.
By using an HDD, you must invest extra time awaiting the outcome of your data ask. Consequently the CPU will be idle for more time, awaiting the HDD to reply. The regular I/O delay for HDD drives is around 7%.

6.Input/Output Request Times

In the real world, SSDs carry out as admirably as they managed for the duration of the testing. We competed a full platform backup using one of our production machines. During the backup operation, the average service time for any I/O demands was indeed under 20 ms.
Using the same hosting server, yet this time built with HDDs, the effects were totally different. The standard service time for any I/O request fluctuated somewhere between 400 and 500 ms.

7. Backup Rates

You can actually experience the real–world added benefits of utilizing SSD drives day–to–day. For instance, with a web server equipped with SSD drives, a full back up can take simply 6 hours.
We utilized HDDs mainly for a few years and we’ve pretty good expertise in exactly how an HDD works. Backing up a server designed with HDD drives is going to take about 20 to 24 hours.

Our Linux VPS packages and then the regular Linux web hosting packages accounts offer SSD drives by default.
