At present, almost all new computer systems come with SSD drives in place of HDD drives. You’ll find superlatives about them everywhere in the specialized press – that they’re a lot quicker and function much better and they are actually the future of desktop computer and laptop computer production.

Nonetheless, how can SSDs stand up within the website hosting environment? Can they be efficient enough to substitute the established HDDs? At LET'S HOST US, we will assist you much better be aware of the differences among an SSD as well as an HDD and judge which one best fits you needs.

1. Access Time

A result of a revolutionary new approach to disk drive performance, SSD drives enable for considerably faster data access speeds. Having an SSD, data accessibility instances tend to be lower (as low as 0.1 millisecond).

The technology driving HDD drives dates all the way back to 1954. And although it’s been drastically processed over time, it’s nonetheless can’t stand up to the revolutionary technology behind SSD drives. Through today’s HDD drives, the best file access rate you’ll be able to reach differs in between 5 and 8 milliseconds.

2. Random I/O Performance

With thanks to the same revolutionary technique which enables for quicker access times, you too can benefit from much better I/O effectiveness with SSD drives. They are able to accomplish double the operations throughout a given time when compared with an HDD drive.

An SSD can deal with at the very least 6000 IO’s per second.

Hard drives provide reduced data file access rates because of the aging file storage and access technique they’re by making use of. And they also exhibit substantially reduced random I/O performance as compared to SSD drives.

For the duration of our tests, HDD drives addressed typically 400 IO operations per second.

3. Reliability

SSD drives are designed to have as fewer moving elements as possible. They utilize a similar concept like the one found in flash drives and are much more dependable compared with standard HDD drives.

SSDs have an average failing rate of 0.5%.

HDD drives make use of spinning disks for keeping and reading info – a technology dating back to the 1950s. And with disks magnetically hanging in mid–air, rotating at 7200 rpm, the prospect of something going wrong are generally higher.

The common rate of failure of HDD drives ranges between 2% and 5%.

4. Energy Conservation

SSD drives are far smaller compared to HDD drives as well as they lack just about any moving elements at all. Consequently they don’t generate just as much heat and need less power to operate and much less power for cooling down reasons.

SSDs take in between 2 and 5 watts.

HDD drives are renowned for staying loud. They require extra electric power for air conditioning purposes. Within a server containing a number of HDDs running all the time, you’ll need a lot of fans to keep them cool – this may cause them far less energy–economical than SSD drives.

HDDs take in in between 6 and 15 watts.

5. CPU Power

Because of SSD drives’ higher I/O efficiency, the leading hosting server CPU can process data file demands much faster and conserve time for additional procedures.

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

HDD drives permit sluggish access speeds in comparison to SSDs do, resulting for the CPU needing to hang around, whilst scheduling resources for your HDD to locate and give back the required data file.

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

6.Input/Output Request Times

In real life, SSDs carry out as wonderfully as they have in the course of the trials. We competed a complete system data backup using one of the production servers. During the backup process, the regular service time for I/O demands was indeed under 20 ms.

Weighed against SSD drives, HDDs deliver noticeably reduced service times for I/O demands. Throughout a web server backup, the standard service time for any I/O request ranges between 400 and 500 ms.

7. Backup Rates

Talking about back ups and SSDs – we have spotted an effective advancement in the data backup rate since we switched to SSDs. Currently, a common hosting server back up takes merely 6 hours.

Over the years, we have got utilized primarily HDD drives on our servers and we are familiar with their overall performance. On a web server equipped with HDD drives, a full server back–up will take around 20 to 24 hours.

The VPS servers as well as our regular Linux cloud hosting accounts offer SSD drives by default. Be part of our LET'S HOST US family, to see how we can assist you transform your website.
