For many years there was only 1 reliable method to keep info on a computer – having a hard drive (HDD). On the other hand, this kind of technology is actually showing it’s age – hard disk drives are really loud and slow; they are power–ravenous and frequently generate lots of heat for the duration of intensive operations.

SSD drives, alternatively, are fast, use up significantly less power and are generally much cooler. They furnish an innovative method of file access and storage and are years in advance of HDDs in relation to file read/write speed, I/O effectiveness and then energy efficiency. Find out how HDDs fare against the more recent SSD drives.

1. Access Time

Image

With the introduction of SSD drives, file accessibility speeds are now tremendous. On account of the brand new electronic interfaces made use of in SSD drives, the normal data access time has been reduced to a record low of 0.1millisecond.

Image

HDD drives even now utilize the very same fundamental file access technology that’s actually developed in the 1950s. Even though it was much improved since then, it’s sluggish as compared to what SSDs will offer. HDD drives’ data access speed ranges in between 5 and 8 milliseconds.

2. Random I/O Performance

Image

The random I/O performance is vital for the operation of a file storage device. We have executed extensive tests and have determined that an SSD can manage at least 6000 IO’s per second.

Image

With an HDD drive, the I/O performance steadily enhances the more you employ the drive. Nevertheless, just after it actually reaches a certain cap, it can’t proceed quicker. And because of the now–old technology, that I/O limit is significantly lower than what you could receive with a SSD.

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

3. Reliability

Image

The lack of moving elements and spinning disks inside SSD drives, and the current developments in electrical interface technology have generated a significantly risk–free file storage device, having a common failing rate of 0.5%.

Image

HDD drives use rotating hard disks for holding and browsing files – a concept since the 1950s. And with disks magnetically suspended in the air, rotating at 7200 rpm, the likelihood of one thing failing are usually bigger.

The common rate of failing of HDD drives can vary amongst 2% and 5%.

4. Energy Conservation

Image

SSDs lack moving parts and require very little chilling power. In addition they call for a small amount of electricity to work – tests have indicated that they’ll be operated by a normal AA battery.

In general, SSDs take in amongst 2 and 5 watts.

Image

From the moment they have been built, HDDs have invariably been extremely power–hungry products. So when you have a web server with many types of HDD drives, this will likely increase the regular electricity bill.

Normally, HDDs take in somewhere between 6 and 15 watts.

5. CPU Power

Image

SSD drives allow for quicker data accessibility speeds, which, in turn, enable the processor to complete file queries considerably faster and to return to additional responsibilities.

The regular I/O wait for SSD drives is simply 1%.

Image

If you use an HDD, you must dedicate additional time waiting around for the outcome of one’s data file query. This means that the CPU will remain idle for extra time, waiting around for the HDD to respond.

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

6.Input/Output Request Times

Image

In real life, SSDs conduct as admirably as they managed throughout the testing. We ran a full platform backup using one of the production web servers. Through the backup procedure, the typical service time for any I/O calls was in fact under 20 ms.

Image

Throughout the identical trials with the exact same hosting server, this time around equipped out with HDDs, efficiency was significantly slow. During the web server back–up procedure, the standard service time for I/O calls fluctuated between 400 and 500 ms.

7. Backup Rates

Image

You’re able to check out the real–world great things about using SSD drives day after day. As an example, with a hosting server equipped with SSD drives, a full back–up will take simply 6 hours.

Image

Throughout the years, we have got utilized predominantly HDD drives with our machines and we’re familiar with their efficiency. With a hosting server built with HDD drives, an entire web server backup typically takes around 20 to 24 hours.

Our Linux VPS web hosting packages and the regular Linux cloud web hosting accounts offer SSD drives automatically. Be a part of our family here, at MozDudes Hosting, to see how we can help you improve your website.
