SSDs vs HDDs
Find out which storage space service is better for your hosting account
These days, almost all brand new computer systems are equipped with SSD drives as an alternative to HDD drives. You can find superlatives about them everywhere in the specialised press – they are faster and perform far better and that they are really the future of home pc and laptop computer production.
On the other hand, how can SSDs stand up within the web hosting environment? Can they be dependable enough to replace the successful HDDs? At OnLine-A-Go-Go, we are going to make it easier to better see the dissimilarities in between an SSD and an HDD and judge the one that best suits you needs.
1. Access Time
Because of a radical new solution to disk drive functionality, SSD drives permit for faster file accessibility rates. With an SSD, data access instances are far lower (as low as 0.1 millisecond).
HDD drives still use the exact same basic data access technology that’s actually developed in the 1950s. Despite the fact that it has been substantially advanced ever since, it’s slow in comparison with what SSDs will provide. HDD drives’ data access rate can vary somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
On account of the brand new significant data storage solution embraced by SSDs, they have speedier data access speeds and swifter random I/O performance.
During OnLine-A-Go-Go’s tests, all of the SSDs confirmed their capacity to take care of at the very least 6000 IO’s per second.
With an HDD drive, the I/O performance steadily increases the more you apply the drive. Even so, right after it extends to a specific restriction, it can’t get swifter. And due to the now–old concept, that I/O limitation is a lot below what you could receive with a SSD.
HDD are only able to go as far as 400 IO’s per second.
3. Reliability
SSD drives are built to have as less moving components as is practical. They utilize a comparable technology to the one found in flash drives and are generally much more reliable as compared to common HDD drives.
SSDs provide an average failing rate of 0.5%.
HDD drives employ spinning disks for keeping and reading through info – a technology dating back to the 1950s. And with disks magnetically suspended in the air, spinning at 7200 rpm, the prospects of some thing going wrong are generally higher.
The regular rate of failing of HDD drives ranges between 2% and 5%.
4. Energy Conservation
SSDs are lacking moving components and need very little chilling energy. They also involve very little energy to operate – trials have demostrated that they can be operated by a standard AA battery.
As a whole, SSDs consume between 2 and 5 watts.
HDD drives are renowned for being noisy. They demand more power for air conditioning purposes. Within a web server which has a lot of HDDs running regularly, you will need a large amount of fans to make sure they’re kept cool – this will make them far less energy–effective than SSD drives.
HDDs take in in between 6 and 15 watts.
5. CPU Power
The speedier the data file accessibility rate is, the quicker the data queries are going to be processed. Consequently the CPU won’t have to reserve resources waiting around for the SSD to respond back.
The common I/O wait for SSD drives is simply 1%.
HDD drives accommodate sluggish accessibility rates when compared with SSDs do, resulting in the CPU being forced to hang around, whilst reserving assets for the HDD to find and return the requested data file.
The typical I/O wait for HDD drives is approximately 7%.
6.Input/Output Request Times
In real life, SSDs function as perfectly as they performed in the course of the trials. We ran an entire platform backup using one of our production web servers. All through the backup operation, the typical service time for any I/O queries was in fact below 20 ms.
Throughout the identical trials sticking with the same hosting server, this time fitted out using HDDs, performance was substantially slow. All through the hosting server data backup procedure, the common service time for any I/O requests varied somewhere between 400 and 500 ms.
7. Backup Rates
Another real–life development will be the speed with which the data backup is created. With SSDs, a hosting server back–up now can take no more than 6 hours by making use of our web server–enhanced software.
On the flip side, with a server with HDD drives, a comparable back up will take three or four times as long to complete. A complete backup of an HDD–powered hosting server may take 20 to 24 hours.
To be able to promptly improve the overall effectiveness of your respective web sites and never having to adjust any code, an SSD–equipped hosting solution will be a very good option. Check the hosting service packages as well as the Linux VPS servers – these hosting solutions highlight swift SSD drives and are offered at good prices.
