For decades there was just one single reputable option to keep info on a pc – employing a hard drive (HDD). On the other hand, this sort of technology is currently showing it’s age – hard disk drives are really loud and slow; they can be power–ravenous and frequently create lots of warmth throughout intense operations.

SSD drives, on the other hand, are swift, use up much less power and are also much cooler. They offer a completely new approach to file access and storage and are years ahead of HDDs in relation to file read/write speed, I/O performance and also energy effectivity. See how HDDs stand up up against the more recent SSD drives.

1. Access Time

Due to a radical new approach to disk drive operation, SSD drives allow for faster data accessibility speeds. With an SSD, file accessibility instances are much lower (as low as 0.1 millisecond).

Image

The technology powering HDD drives goes back to 1954. And even while it has been drastically polished progressively, it’s still no match for the innovative ideas behind SSD drives. Using today’s HDD drives, the top data access rate you can actually reach differs somewhere between 5 and 8 milliseconds.

2. Random I/O Performance

Image

The random I/O performance is vital for the performance of any file storage device. We’ve run substantial exams and have established an SSD can deal with no less than 6000 IO’s per second.

Image

Throughout the same lab tests, the HDD drives proved to be much slower, with simply 400 IO operations maintained per second. Even though this feels like a good deal, for those who have a busy server that contains numerous well–liked sites, a sluggish hard disk can cause slow–loading websites.

3. Reliability

Image

SSD drives lack any rotating components, which means there is far less machinery inside them. And the less actually moving elements you can find, the fewer the likelihood of failing can be.

The regular rate of failing of any SSD drive is 0.5%.

Image

HDD drives implement spinning hard disks for keeping and reading files – a concept dating back to the 1950s. Along with disks magnetically hanging in the air, rotating at 7200 rpm, the odds of one thing failing are much increased.

The regular rate of failure of HDD drives varies among 2% and 5%.

4. Energy Conservation

Image

SSDs don’t have moving elements and need hardly any cooling power. In addition, they involve a small amount of energy to operate – tests have demonstrated they can be operated by a standard AA battery.

As a whole, SSDs use up amongst 2 and 5 watts.

Image

HDD drives are renowned for being noisy. They need a lot more energy for air conditioning applications. On a server which includes a lot of different HDDs running continuously, you will need a good deal of fans to make sure they’re cool – this may cause them far less energy–economical than SSD drives.

HDDs consume in between 6 and 15 watts.

5. CPU Power

Image

SSD drives permit faster data file accessibility rates, which, consequently, permit the processor to complete data queries considerably faster and to return to additional jobs.

The average I/O wait for SSD drives is just 1%.

Image

As compared with SSDs, HDDs permit not so quick data accessibility speeds. The CPU must wait around for the HDD to come back the requested data file, reserving its allocations in the meantime.

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

6.Input/Output Request Times

Image

It is time for a few real–world cases. We, at Rocket Hosting, produced a detailed system backup on a web server only using SSDs for data storage uses. During that process, the regular service time for an I/O request remained under 20 ms.

Image

With the exact same web server, however, this time equipped with HDDs, the end results were very different. The regular service time for an I/O query changed in between 400 and 500 ms.

7. Backup Rates

Image

Another real–life improvement is the speed at which the data backup has been made. With SSDs, a web server back–up today takes no more than 6 hours by using Rocket Hosting’s hosting server–enhanced software solutions.

Image

On the other hand, on a hosting server with HDD drives, a comparable data backup normally takes three to four times as long to finish. An entire back up of an HDD–driven server typically takes 20 to 24 hours.

The Linux VPS hosting packages along with our routine Linux shared web hosting packages accounts have SSD drives by default. Be part of our Rocket Hosting family, and discover the way we just might help you supercharge your web site.
