SSDs vs HDDs
Browse the Pro’s and Con’s of HDD and SSD drives
If you have a web site or maybe an web application, pace is vital. The quicker your website functions and then the speedier your web apps operate, the better for everyone. Given that a web site is simply a number of files that communicate with each other, the systems that store and work with these files have a huge role in web site functionality.
Hard drives, or HDDs, were, right up until recent years, the most trusted systems for saving data. Having said that, in recent times solid–state drives, or SSDs, have already been rising in popularity. Look at our evaluation chart to find out whether HDDs or SSDs are more suitable for you.
1. Access Time
After the introduction of SSD drives, data access speeds have gone tremendous. As a result of completely new electronic interfaces utilized in SSD drives, the average file access time has been reduced to a all–time low of 0.1millisecond.
The technology driving HDD drives dates all the way to 1954. Even though it’s been substantially polished through the years, it’s still can’t stand up to the ground breaking concept behind SSD drives. Having today’s HDD drives, the very best file access speed it is possible to reach can vary somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
Because of the new revolutionary data file storage technique adopted by SSDs, they feature speedier data access speeds and faster random I/O performance.
For the duration of our trials, all SSDs showed their capacity to manage at the very least 6000 IO’s per second.
With a HDD drive, the I/O performance gradually raises the more you employ the drive. Even so, in the past it actually reaches a specific limit, it can’t get speedier. And because of the now–old concept, that I/O cap is noticeably lower than what you might get having an SSD.
HDD are only able to go as much as 400 IO’s per second.
3. Reliability
The absence of moving elements and spinning disks in SSD drives, and the current advances in electric interface technology have ended in a much reliable file storage device, with a common failing rate of 0.5%.
For an HDD drive to work, it should rotate two metallic disks at over 7200 rpm, keeping them magnetically stable in mid–air. They have a lot of moving elements, motors, magnets and also other gadgets jammed in a tiny location. Hence it’s no wonder that the average rate of failure of an HDD drive varies in between 2% and 5%.
4. Energy Conservation
SSD drives are considerably smaller compared to HDD drives and also they don’t have any kind of moving elements at all. Consequently they don’t make so much heat and require much less energy to operate and fewer energy for cooling down purposes.
SSDs use up between 2 and 5 watts.
HDD drives are infamous for getting loud; they’re at risk of overheating and if you have several hard drives in a single web server, you will need one more air conditioning system used only for them.
All together, HDDs use up somewhere between 6 and 15 watts.
5. CPU Power
SSD drives provide for swifter data access speeds, that, in turn, permit the processor to complete data queries much faster and then to return to other tasks.
The standard I/O hold out for SSD drives is 1%.
HDD drives allow for reduced access rates in comparison with SSDs do, which will result for the CPU required to delay, whilst reserving assets for the HDD to locate and give back the required data.
The regular I/O wait for HDD drives is just about 7%.
6.Input/Output Request Times
In real life, SSDs conduct as perfectly as they did in the course of our tests. We produced a full platform back–up using one of our own production servers. Throughout the backup procedure, the standard service time for I/O calls was basically below 20 ms.
Using the same hosting server, however this time built with HDDs, the results were different. The regular service time for any I/O call changed in between 400 and 500 ms.
7. Backup Rates
Another real–life development is the speed at which the back–up has been developed. With SSDs, a web server data backup currently will take under 6 hours implementing our server–enhanced software solutions.
On the flip side, on a hosting server with HDD drives, a similar data backup can take 3 to 4 times as long to finish. An entire backup of an HDD–driven hosting server may take 20 to 24 hours.
If you want to promptly improve the effectiveness of your websites while not having to change just about any code, an SSD–operated website hosting service will be a good solution. Look at TreeCloudHost’s Linux shared service packages and then our Linux VPS web hosting service – these hosting solutions highlight really fast SSD drives and are offered at cheap prices.
