For years there seemed to be only 1 reliable way to store information on your personal computer – having a disk drive (HDD). Then again, this type of technology is actually displaying its age – hard disk drives are loud and sluggish; they are power–hungry and have a tendency to produce a lot of warmth during intense procedures.

SSD drives, in contrast, are really fast, take in far less power and are generally much cooler. They feature a brand new solution to file access and storage and are years in advance of HDDs when it comes to file read/write speed, I/O efficiency and then energy effectivity. See how HDDs fare against the more recent SSD drives.

1. Access Time

SSD drives provide a brand new & impressive approach to file safe–keeping according to the utilization of electronic interfaces in place of any kind of moving parts and spinning disks. This unique technology is considerably faster, making it possible for a 0.1 millisecond data file access time.

HDD drives rely on rotating disks for data storage uses. Each time a file is being utilized, you need to wait around for the correct disk to reach the appropriate position for the laser beam to view the file in question. This translates into a typical access speed of 5 to 8 milliseconds.

2. Random I/O Performance

Resulting from the unique radical data storage technique embraced by SSDs, they offer better data access speeds and better random I/O performance.

All through our tests, all SSDs showed their ability to handle at the very least 6000 IO’s per second.

All through the exact same lab tests, the HDD drives confirmed to be significantly slower, with 400 IO operations maintained per second. Although this may appear to be a great number, when you have an overloaded server that serves a lot of well–known sites, a slow hard disk drive can cause slow–loading web sites.

3. Reliability

SSD drives don’t have any kind of rotating parts, meaning there’s much less machinery included. And the less actually moving components you will discover, the fewer the chances of failing are going to be.

The regular rate of failure of an SSD drive is 0.5%.

HDD drives utilize rotating disks for storing and reading through files – a technology dating back to the 1950s. Along with hard disks magnetically hanging in the air, spinning at 7200 rpm, the chances of anything going wrong are much higher.

The standard rate of failing of HDD drives varies amongst 2% and 5%.

4. Energy Conservation

SSDs don’t have moving parts and require little or no cooling down energy. In addition they involve a small amount of power to work – trials have established that they can be operated by a common AA battery.

As a whole, SSDs take in amongst 2 and 5 watts.

HDD drives are well known for being noisy; they’re prone to overheating and in case you have several disk drives in one hosting server, you need one more cooling device exclusively for them.

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

5. CPU Power

As a result of SSD drives’ better I/O effectiveness, the key web server CPU can process file queries more quickly and save time for other operations.

The regular I/O delay for SSD drives is just 1%.

As compared to SSDs, HDDs enable not so quick data file access speeds. The CPU is going to wait for the HDD to return the requested file, scheduling its assets in the meantime.

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

6.Input/Output Request Times

It is time for a few real–world illustrations. We produced an entire system backup with a web server only using SSDs for file storage reasons. In that procedure, the average service time for any I/O query remained below 20 ms.

Using the same server, however, this time furnished with HDDs, the outcome were completely different. The standard service time for an I/O call changed in between 400 and 500 ms.

7. Backup Rates

Another real–life improvement is the rate at which the data backup has been developed. With SSDs, a server backup currently can take only 6 hours by making use of Renstay’s hosting server–optimized software.

We utilized HDDs exclusively for a couple of years and we have got very good knowledge of precisely how an HDD performs. Generating a backup for a server furnished with HDD drives will take about 20 to 24 hours.

Our Linux VPS servers and additionally the typical shared web hosting plans accounts offer SSD drives by default. Be a part of our Renstay family, and see the way we can assist you boost your site.
