When you have a web site or perhaps an web application, speed is extremely important. The swifter your website works and then the swifter your applications operate, the better for everyone. Considering that a website is only a number of files that interact with each other, the systems that store and access these data files play a vital role in web site performance.

Hard drives, or HDDs, were, until recent years, the most dependable systems for saving information. Having said that, in recent times solid–state drives, or SSDs, have already been becoming more popular. Check out our comparison chart to determine if HDDs or SSDs are more effective for you.

1. Access Time

Image

After the arrival of SSD drives, data access speeds are now tremendous. Because of the completely new electronic interfaces employed in SSD drives, the common data file access time has been reduced to a all–time low of 0.1millisecond.

Image

The concept powering HDD drives times back to 1954. And although it has been considerably polished progressively, it’s nevertheless can’t stand up to the revolutionary concept behind SSD drives. Having today’s HDD drives, the highest data file access rate you are able to attain varies somewhere between 5 and 8 milliseconds.

2. Random I/O Performance

Image

Due to the very same revolutionary method which allows for a lot faster access times, you too can appreciate greater I/O performance with SSD drives. They are able to accomplish twice as many procedures throughout a given time when compared to an HDD drive.

An SSD can manage at the least 6000 IO’s per second.

Image

Having an HDD drive, the I/O performance steadily increases the more you employ the disk drive. Nevertheless, as soon as it reaches a certain limitation, it can’t proceed quicker. And because of the now–old concept, that I/O cap is noticeably less than what you might find having an SSD.

HDD are only able to go as much as 400 IO’s per second.

3. Reliability

Image

The absence of moving elements and rotating disks inside SSD drives, and the recent advancements in electric interface technology have generated a significantly less risky data storage device, with a common failure rate of 0.5%.

Image

For an HDD drive to operate, it should spin a couple metallic hard disks at more than 7200 rpm, retaining them magnetically stable in the air. They have a great deal of moving components, motors, magnets as well as other gadgets crammed in a small location. Therefore it’s no surprise that the common rate of failing of the HDD drive varies somewhere between 2% and 5%.

4. Energy Conservation

Image

SSDs do not have moving elements and need hardly any chilling energy. They also call for very little power to operate – trials have indicated that they can be operated by a normal AA battery.

In general, SSDs consume amongst 2 and 5 watts.

Image

HDD drives are known for getting loud; they are more prone to getting too hot and whenever you have several hard drives inside a web server, you have to have a further air conditioning device used only for them.

As a whole, HDDs consume between 6 and 15 watts.

5. CPU Power

Image

The swifter the file access speed is, the swifter the data file calls will be treated. Therefore the CPU will not have to arrange resources waiting for the SSD to respond back.

The average I/O delay for SSD drives is simply 1%.

Image

By using an HDD, you will have to invest more time anticipating the outcome of one’s data file ask. Consequently the CPU will remain idle for much more time, waiting around for the HDD to react.

The normal I/O delay for HDD drives is approximately 7%.

6.Input/Output Request Times

Image

It is time for a few real–world instances. We, at gobighosts, competed an entire system backup with a hosting server only using SSDs for data storage reasons. During that process, the typical service time for any I/O request kept beneath 20 ms.

Image

In comparison to SSD drives, HDDs offer substantially reduced service rates for I/O requests. Throughout a web server backup, the common service time for any I/O request ranges somewhere between 400 and 500 ms.

7. Backup Rates

Image

You can actually check out the real–world advantages of having SSD drives daily. For instance, on a server loaded with SSD drives, a complete backup will take simply 6 hours.

Image

We used HDDs exclusively for a couple of years and we have got excellent familiarity with how an HDD works. Generating a backup for a server designed with HDD drives will take around 20 to 24 hours.

Our Linux VPS servers and also our typical Linux cloud hosting plans accounts have SSD drives automatically. Be part of our gobighosts family, and discover how we just might help you improve your website.
