SSDs vs HDDs
Compare and contrast the two industry–leading data storage space devices
At present, virtually all new personal computers contain SSD drives as an alternative for HDD drives. One can find superlatives on them everywhere in the specialised press – they are faster and operate much better and they are actually the future of home computer and laptop manufacturing.
Having said that, how do SSDs fare in the hosting community? Are they dependable enough to replace the proven HDDs? At Anas Hosting, we will help you much better be aware of the distinctions among an SSD and an HDD and decide the one that most closely fits you needs.
1. Access Time
With the release of SSD drives, file accessibility speeds have gone tremendous. As a result of unique electronic interfaces employed in SSD drives, the average data file access time has been reduced into a record low of 0.1millisecond.
The concept powering HDD drives goes all the way back to 1954. And even while it’s been considerably polished progressively, it’s nevertheless can’t stand up to the innovative technology behind SSD drives. Utilizing today’s HDD drives, the top data file access speed it is possible to achieve varies somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Thanks to the exact same radical method allowing for better access times, it’s also possible to take pleasure in improved I/O performance with SSD drives. They’re able to accomplish two times as many functions within a specific time in comparison to an HDD drive.
An SSD can manage at the very least 6000 IO’s per second.
Hard drives present slower file access speeds due to older file storage and access technology they are by making use of. And in addition they display significantly sluggish random I/O performance compared with SSD drives.
Throughout our trials, HDD drives addressed on average 400 IO operations per second.
3. Reliability
SSD drives do not have any kind of moving components, which means there is much less machinery within them. And the less physically moving parts you will discover, the lower the chances of failing are going to be.
The standard rate of failure of an SSD drive is 0.5%.
HDD drives make use of rotating hard disks for storing and reading through info – a concept dating back to the 1950s. And with hard disks magnetically suspended in mid–air, rotating at 7200 rpm, the prospect of anything going wrong are much increased.
The common rate of failure of HDD drives varies amongst 2% and 5%.
4. Energy Conservation
SSD drives are considerably smaller compared to HDD drives and also they lack any kind of moving elements whatsoever. As a result they don’t generate so much heat and need a lot less electricity to function and less energy for chilling purposes.
SSDs take in between 2 and 5 watts.
From the moment they have been developed, HDDs have always been very electrical power–ravenous equipment. And when you have a hosting server with a couple of HDD drives, this will add to the month to month utility bill.
On average, HDDs consume between 6 and 15 watts.
5. CPU Power
The swifter the file access rate is, the swifter the file queries are going to be adressed. This means that the CPU do not need to reserve assets looking forward to the SSD to respond back.
The average I/O delay for SSD drives is barely 1%.
Compared with SSDs, HDDs permit slower file access speeds. The CPU is going to wait for the HDD to return the demanded data file, reserving its resources for the time being.
The common I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
In the real world, SSDs conduct as perfectly as they did in the course of the tests. We produced a full platform back–up using one of our production servers. During the backup process, the common service time for any I/O requests was in fact below 20 ms.
With the exact same web server, however this time loaded with HDDs, the effects were very different. The common service time for an I/O request fluctuated in between 400 and 500 ms.
7. Backup Rates
One more real–life advancement is the rate at which the backup was developed. With SSDs, a hosting server data backup currently requires under 6 hours using Anas Hosting’s server–enhanced software solutions.
We applied HDDs exclusively for a couple of years and we have very good understanding of exactly how an HDD functions. Backing up a web server furnished with HDD drives is going to take about 20 to 24 hours.
Should you wish to instantaneously add to the overall performance of your sites and not having to adjust any code, an SSD–driven website hosting service is really a very good solution. Look at the Linux cloud website hosting packages plus our VPS web hosting services – our services have extremely fast SSD drives and can be found at the best prices.
