Currently, all of the new computer systems come with SSD drives as a substitute for HDD drives. You’ll find superlatives to them everywhere in the professional press – that they’re quicker and operate better and that they are actually the future of home computer and laptop manufacturing.

Nonetheless, how can SSDs perform in the web hosting world? Could they be trustworthy enough to replace the proved HDDs? At Cloudcroft Online, we will make it easier to much better understand the differences in between an SSD as well as an HDD and determine which one is best suited for you needs.

1. Access Time

After the introduction of SSD drives, file access rates have gone tremendous. On account of the new electronic interfaces utilized in SSD drives, the standard data access time has shrunk to a all–time low of 0.1millisecond.

HDD drives make use of rotating disks for files storage applications. When a file will be utilized, you will have to wait around for the correct disk to get to the correct position for the laser beam to view the file involved. This ends in a standard access rate of 5 to 8 milliseconds.

2. Random I/O Performance

The random I/O performance is important for the functionality of any data file storage device. We’ve carried out substantial trials and have confirmed an SSD can handle no less than 6000 IO’s per second.

All through the very same lab tests, the HDD drives demonstrated to be significantly slower, with simply 400 IO operations addressed per second. While this might appear to be a large amount, when you have an overloaded web server that serves many sought after web sites, a slow harddrive can lead to slow–loading sites.

3. Reliability

SSD drives are built to have as fewer rotating components as feasible. They utilize an identical concept like the one employed in flash drives and are more trustworthy when compared to traditional HDD drives.

SSDs provide an normal failure rate of 0.5%.

HDD drives employ rotating disks for saving and browsing data – a technology dating back to the 1950s. Along with disks magnetically suspended in the air, spinning at 7200 rpm, the likelihood of something failing are considerably higher.

The normal rate of failure of HDD drives ranges amongst 2% and 5%.

4. Energy Conservation

SSD drives work virtually silently; they don’t make excess warmth; they don’t demand extra air conditioning alternatives as well as use up less energy.

Lab tests have demostrated that the average electrical power utilization of an SSD drive is somewhere between 2 and 5 watts.

HDD drives are famous for becoming loud. They demand far more energy for cooling applications. Within a hosting server containing a lot of different HDDs running constantly, you will need a great number of fans to ensure they are cool – this may cause them a lot less energy–effective than SSD drives.

HDDs consume in between 6 and 15 watts.

5. CPU Power

The faster the data accessibility speed is, the quicker the file requests will likely be processed. As a result the CPU will not have to reserve resources expecting the SSD to answer back.

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

As compared with SSDs, HDDs allow for not so quick data file access speeds. The CPU must await the HDD to send back the required data file, saving its assets for the time being.

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

6.Input/Output Request Times

It’s about time for several real–world illustrations. We produced a complete system backup on a hosting server only using SSDs for file storage reasons. In that procedure, the typical service time for any I/O call remained beneath 20 ms.

With the same web server, but this time furnished with HDDs, the end results were completely different. The average service time for an I/O request changed between 400 and 500 ms.

7. Backup Rates

Speaking about back ups and SSDs – we’ve discovered an amazing progress with the back–up rate since we moved to SSDs. Right now, a regular server back up takes merely 6 hours.

We applied HDDs mainly for a couple of years and we have great comprehension of exactly how an HDD runs. Generating a backup for a server furnished with HDD drives is going to take about 20 to 24 hours.
