Currently, all new computers are equipped with SSD drives as an alternative to HDD drives. You will see superlatives to them all over the specialised press – that they are quicker and perform much better and that they are actually the future of desktop computer and laptop computer generation.
Then again, how do SSDs perform within the website hosting community? Could they be reliable enough to substitute the proven HDDs? At Apache Website Hosting, we will assist you to much better understand the dissimilarities between an SSD as well as an HDD and determine which one best suits you needs.
1. Access Time
Due to a radical new solution to disk drive functionality, SSD drives allow for considerably faster data file accessibility rates. With an SSD, file accessibility times tend to be lower (under 0.1 millisecond).
The technology driving HDD drives dates all the way back to 1954. And while it has been considerably processed over time, it’s still no match for the inventive technology powering SSD drives. Having today’s HDD drives, the top data access speed you’ll be able to attain can vary somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Due to the unique radical data storage strategy incorporated by SSDs, they provide faster file access speeds and swifter random I/O performance.
For the duration of Apache Website Hosting’s tests, all SSDs demonstrated their capacity to work with at the least 6000 IO’s per second.
Having an HDD drive, the I/O performance steadily increases the more you employ the disk drive. Even so, once it actually reaches a specific limit, it can’t get faster. And due to the now–old concept, that I/O restriction is significantly lower than what you can find having an SSD.
HDD are only able to go as far as 400 IO’s per second.
SSD drives do not have any rotating parts, meaning there’s far less machinery included. And the less physically moving components you’ll find, the lower the likelihood of failure will be.
The normal rate of failure of any SSD drive is 0.5%.
HDD drives utilize rotating hard disks for holding and reading files – a concept since the 1950s. With hard disks magnetically hanging in the air, rotating at 7200 rpm, the prospects of some thing failing are usually increased.
The average rate of failing of HDD drives ranges between 2% and 5%.
4. Energy Conservation
SSDs don’t have moving components and require minimal chilling power. In addition they demand not much power to operate – trials have demostrated that they can be operated by a standard AA battery.
In general, SSDs use up amongst 2 and 5 watts.
HDD drives are renowned for being noisy. They demand far more energy for cooling down purposes. With a hosting server which has a lot of different HDDs running continually, you will need a large amount of fans to ensure they are cooler – this will make them far less energy–effective than SSD drives.
HDDs consume somewhere between 6 and 15 watts.
5. CPU Power
Thanks to SSD drives’ better I/O effectiveness, the main server CPU can process data file calls more rapidly and conserve time for other procedures.
The standard I/O delay for SSD drives is exactly 1%.
If you use an HDD, you have to dedicate time looking forward to the outcomes of your data file query. As a result the CPU will be idle for additional time, waiting for the HDD to reply.
The common I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
The majority of our brand new web servers now use just SSD drives. Our very own lab tests have demostrated that having an SSD, the typical service time for any I/O request while running a backup continues to be under 20 ms.
With the exact same server, however this time built with HDDs, the outcome were completely different. The regular service time for an I/O call changed between 400 and 500 ms.
7. Backup Rates
You are able to experience the real–world potential benefits to using SSD drives day–to–day. As an example, on a web server designed with SSD drives, a full data backup is going to take merely 6 hours.
We applied HDDs mainly for several years and we’ve decent comprehension of just how an HDD performs. Generating a backup for a hosting server furnished with HDD drives can take around 20 to 24 hours.
