At present, pretty much all completely new computing devices come with SSD drives as a substitute for HDD drives. One can find superlatives on them everywhere in the specialized press – that they are faster and function much better and that they are really the future of home pc and laptop manufacturing.
Even so, how do SSDs stand up in the web hosting community? Are they reliable enough to replace the verified HDDs? At RadialHosting, we will assist you much better understand the differences in between an SSD and an HDD and determine which one best fits you needs.
1. Access Time
With the release of SSD drives, data access speeds have gone over the top. As a result of brand new electronic interfaces employed in SSD drives, the typical file access time has been reduced to a record low of 0.1millisecond.
HDD drives make use of spinning disks for files storage applications. Every time a file is being accessed, you have to wait for the appropriate disk to get to the right position for the laser beam to view the file you want. This ends in a common access rate of 5 to 8 milliseconds.
2. Random I/O Performance
The random I/O performance is very important for the overall performance of a data file storage device. We’ve carried out thorough trials and have established that an SSD can manage at the very least 6000 IO’s per second.
Throughout the very same trials, the HDD drives demonstrated that they are significantly slower, with 400 IO operations addressed per second. Although this seems to be a large number, if you have a busy web server that contains many famous sites, a sluggish disk drive can lead to slow–loading web sites.
SSD drives do not have just about any moving parts, meaning there’s significantly less machinery in them. And the less physically moving parts you’ll find, the lower the chances of failing will be.
The normal rate of failing of an SSD drive is 0.5%.
With an HDD drive to work, it needs to rotate a pair of metallic disks at over 7200 rpm, retaining them magnetically stabilized in mid–air. There is a large amount of moving parts, motors, magnets and also other gadgets loaded in a tiny place. Consequently it’s no wonder that the common rate of failure of any HDD drive ranges somewhere between 2% and 5%.
4. Energy Conservation
SSD drives operate almost noiselessly; they don’t produce excess warmth; they don’t demand additional cooling down solutions and then consume way less power.
Trials have demostrated the common electric power intake of an SSD drive is somewhere between 2 and 5 watts.
From the second they have been built, HDDs have invariably been very energy–greedy products. So when you have a server with many types of HDD drives, this will raise the per month power bill.
On average, HDDs use up somewhere between 6 and 15 watts.
5. CPU Power
Thanks to SSD drives’ greater I/O performance, the main hosting server CPU will be able to work with data file requests more quickly and preserve time for other operations.
The average I/O delay for SSD drives is exactly 1%.
When compared with SSDs, HDDs permit not so quick data file access rates. The CPU is going to wait for the HDD to send back the inquired file, saving its resources for the time being.
The standard I/O delay for HDD drives is around 7%.
6.Input/Output Request Times
In the real world, SSDs perform as wonderfully as they have throughout the tests. We produced a full system data backup on one of our production web servers. Through the backup procedure, the average service time for I/O calls was under 20 ms.
All through the same trials sticking with the same hosting server, this time around equipped out with HDDs, performance was significantly slow. All through the hosting server data backup process, the normal service time for I/O demands varied somewhere between 400 and 500 ms.
7. Backup Rates
You’ll be able to notice the real–world advantages of using SSD drives on a regular basis. By way of example, on a web server furnished with SSD drives, a full backup will take just 6 hours.
On the other hand, with a hosting server with HDD drives, a similar data backup usually requires 3 to 4 times as long in order to complete. A full back up of any HDD–equipped web server normally takes 20 to 24 hours.
