SSDs vs HDDs
Compare the 2 industry–leading data storage devices
For people with a website or perhaps an application, pace is crucial. The speedier your web site works and then the swifter your web apps perform, the better for everyone. Given that a site is simply a collection of data files that connect with one another, the systems that store and access these data files play a vital role in website performance.
Hard disks, or HDDs, have been, right until recent years, the most efficient systems for storing data. Then again, in recent times solid–state drives, or SSDs, have been gaining interest. Have a look at our comparability chart to view whether HDDs or SSDs are more suitable for you.
1. Access Time
After the arrival of SSD drives, data access rates are now over the top. As a result of unique electronic interfaces utilized in SSD drives, the typical data file access time has been reduced into a all–time low of 0.1millisecond.
The technology driving HDD drives goes all the way back to 1954. And although it’s been drastically enhanced in recent times, it’s nevertheless no match for the innovative technology powering SSD drives. Using today’s HDD drives, the highest data access speed you’re able to attain may differ somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is really important for the performance of any data storage device. We have carried out in depth trials and have identified an SSD can handle at the least 6000 IO’s per second.
During the same trials, the HDD drives demonstrated that they are considerably slower, with 400 IO operations maintained per second. While this may seem like a large amount, for those who have a hectic server that hosts loads of popular websites, a slow hard disk can lead to slow–loading websites.
3. Reliability
SSD drives are made to include as fewer rotating parts as is feasible. They use a comparable concept like the one used in flash drives and are generally much more efficient in comparison with common HDD drives.
SSDs have an typical failure rate of 0.5%.
HDD drives utilize spinning disks for saving and browsing files – a concept since the 1950s. With hard disks magnetically hanging in mid–air, rotating at 7200 rpm, the prospect of some thing going wrong are usually bigger.
The common rate of failure of HDD drives varies among 2% and 5%.
4. Energy Conservation
SSD drives are much smaller than HDD drives and they lack any moving elements whatsoever. Because of this they don’t make just as much heat and need significantly less power to operate and much less energy for cooling down reasons.
SSDs consume between 2 and 5 watts.
As soon as they have been constructed, HDDs have invariably been really electricity–ravenous products. When you have a web server with several HDD drives, this can increase the regular electric bill.
Typically, HDDs consume somewhere between 6 and 15 watts.
5. CPU Power
SSD drives support better data file accessibility rates, which will, subsequently, allow the CPU to accomplish data queries considerably quicker and to return to different jobs.
The average I/O wait for SSD drives is just 1%.
HDD drives accommodate reduced access rates in comparison with SSDs do, resulting in the CPU being forced to hang around, while arranging resources for your HDD to locate and give back the required file.
The normal I/O delay for HDD drives is around 7%.
6.Input/Output Request Times
Almost all of our brand new web servers are now using simply SSD drives. Our personal tests have established that having an SSD, the typical service time for any I/O request although running a backup remains under 20 ms.
Sticking with the same server, yet this time furnished with HDDs, the end results were different. The standard service time for an I/O query changed somewhere between 400 and 500 ms.
7. Backup Rates
Referring to back–ups and SSDs – we’ve found an amazing improvement in the data backup rate since we switched to SSDs. Currently, a normal hosting server back up can take simply 6 hours.
On the other hand, on a hosting server with HDD drives, the same back up normally takes three or four times as long to finish. An entire back–up of an HDD–powered server usually takes 20 to 24 hours.
The shared hosting plans accounts include SSD drives automatically. Join our family here, at 506Host, to check out how we can assist you supercharge your web site.
