For decades there was a single efficient method to store info on your computer – working with a hard drive (HDD). Then again, this sort of technology is by now expressing its age – hard disk drives are noisy and sluggish; they can be power–ravenous and tend to generate a great deal of heat throughout intensive operations.

SSD drives, on the contrary, are really fast, consume much less power and are generally far less hot. They furnish an innovative method of file accessibility and data storage and are years in advance of HDDs in terms of file read/write speed, I/O efficiency and also energy capability. Find out how HDDs stand up against the modern SSD drives.

1. Access Time

Because of a revolutionary new method of disk drive operation, SSD drives make it possible for noticeably faster data file access rates. Having an SSD, data file accessibility instances are far lower (as little as 0.1 millisecond).

The technology behind HDD drives times back to 1954. Even though it has been substantially polished over the years, it’s still can’t stand up to the innovative concept powering SSD drives. Using today’s HDD drives, the best file access speed you’ll be able to attain varies in between 5 and 8 milliseconds.

2. Random I/O Performance

As a result of the brand–new significant data storage technique adopted by SSDs, they furnish swifter file access speeds and better random I/O performance.

In the course of Acruxnet’s trials, all SSDs revealed their capability to take care of at least 6000 IO’s per second.

Throughout the same lab tests, the HDD drives turned out to be significantly slower, with 400 IO operations addressed per second. While this may seem like a large amount, for people with a busy web server that serves a great deal of famous sites, a sluggish hard disk could lead to slow–loading sites.

3. Reliability

SSD drives are built to include as fewer rotating elements as is practical. They use a comparable concept to the one used in flash drives and are also more reliable as opposed to regular HDD drives.

SSDs provide an average failing rate of 0.5%.

For the HDD drive to function, it should spin a couple metallic disks at over 7200 rpm, keeping them magnetically stabilized in the air. They have a lot of moving elements, motors, magnets as well as other devices loaded in a tiny place. Hence it’s no wonder that the standard rate of failing of any HDD drive ranges in between 2% and 5%.

4. Energy Conservation

SSDs don’t have any moving parts and need hardly any chilling energy. They also call for not much electricity to perform – lab tests have indicated they can be operated by a normal AA battery.

In general, SSDs use up between 2 and 5 watts.

HDD drives are renowned for staying loud. They want extra energy for cooling down reasons. Within a server that has a large number of HDDs running consistently, you’ll need a good deal of fans to make sure they’re cool – this will make them far less energy–effective than SSD drives.

HDDs consume somewhere between 6 and 15 watts.

5. CPU Power

As a result of SSD drives’ better I/O performance, the key hosting server CPU can work with data queries more quickly and save time for additional operations.

The common I/O delay for SSD drives is exactly 1%.

HDD drives enable reduced access rates than SSDs do, resulting for the CPU needing to delay, although saving resources for the HDD to uncover and give back the requested data.

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

6.Input/Output Request Times

In real life, SSDs conduct as perfectly as they managed throughout our tests. We produced an entire platform backup on one of the production machines. Over the backup procedure, the common service time for any I/O requests was in fact below 20 ms.

With the exact same web server, but this time built with HDDs, the effects were totally different. The common service time for any I/O call changed in between 400 and 500 ms.

7. Backup Rates

Talking about back ups and SSDs – we’ve found a great development in the back up speed as we switched to SSDs. Today, a regular server back–up can take solely 6 hours.

We utilized HDDs mainly for a couple of years and we’ve pretty good expertise in just how an HDD performs. Generating a backup for a hosting server furnished with HDD drives can take about 20 to 24 hours.

Should you want to immediately improve the overall performance of your sites while not having to adjust just about any code, an SSD–equipped web hosting solution is really a great option.
