For decades there seemed to be a particular dependable option to store info on your computer – by using a disk drive (HDD). However, this type of technology is already showing its age – hard drives are actually noisy and sluggish; they’re power–ravenous and tend to generate a great deal of warmth during intensive operations.
SSD drives, on the other hand, are extremely fast, use up a lesser amount of energy and are generally much cooler. They furnish a completely new solution to file access and storage and are years ahead of HDDs when it comes to file read/write speed, I/O performance and also energy effectivity. Figure out how HDDs fare against the newer SSD drives.
1. Access Time
SSD drives give a brand–new & ingenious method to data storage based on the use of electronic interfaces in place of any sort of moving parts and revolving disks. This innovative technology is quicker, enabling a 0.1 millisecond data accessibility time.
HDD drives even now make use of the very same fundamental data access technology that’s initially created in the 1950s. Although it was considerably enhanced after that, it’s slow in comparison with what SSDs are providing. HDD drives’ data file access speed ranges between 5 and 8 milliseconds.
2. Random I/O Performance
As a result of the brand–new radical data file storage technique adopted by SSDs, they provide swifter file access speeds and quicker random I/O performance.
In the course of our lab tests, all of the SSDs revealed their ability to handle at the very least 6000 IO’s per second.
Over the very same tests, the HDD drives proved to be significantly slower, with only 400 IO operations maintained per second. Even though this feels like a significant number, when you have a hectic web server that contains a lot of sought after web sites, a slow disk drive could lead to slow–loading websites.
The absence of moving parts and spinning disks inside SSD drives, and the current developments in electronic interface technology have ended in a substantially less risky data storage device, with an average failing rate of 0.5%.
Since we have previously mentioned, HDD drives rely on rotating hard disks. And something that works by using a lot of moving components for lengthy periods of time is susceptible to failure.
HDD drives’ average rate of failure ranges between 2% and 5%.
4. Energy Conservation
SSD drives operate virtually soundlessly; they don’t produce surplus heat; they don’t require additional cooling down alternatives and then consume a lot less electricity.
Trials have demonstrated that the normal electric power utilization of an SSD drive is somewhere between 2 and 5 watts.
HDD drives are famous for becoming loud. They require further electrical power for cooling purposes. On a hosting server which has a number of HDDs running continuously, you need a great number of fans to make sure they’re cool – this makes them far less energy–efficient than SSD drives.
HDDs take in between 6 and 15 watts.
5. CPU Power
SSD drives provide for swifter data file accessibility speeds, that, subsequently, allow the processor to finish file queries faster and after that to go back to different responsibilities.
The regular I/O wait for SSD drives is actually 1%.
When using an HDD, you have to devote time awaiting the outcome of your data file request. As a result the CPU will remain idle for extra time, expecting the HDD to reply.
The typical I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
The vast majority of our brand–new servers are now using just SSD drives. Our very own tests have revealed that using an SSD, the normal service time for any I/O request whilst operating a backup continues to be below 20 ms.
With the exact same server, however this time equipped with HDDs, the effects were different. The standard service time for an I/O request changed in between 400 and 500 ms.
7. Backup Rates
Referring to backups and SSDs – we have detected a fantastic improvement with the backup speed since we transferred to SSDs. Right now, a common server backup will take just 6 hours.
In contrast, on a web server with HDD drives, an identical backup normally requires three to four times as long to complete. A full back up of an HDD–equipped web server often takes 20 to 24 hours.
If you want to right away improve the overall functionality of your respective web sites and not having to transform any code, an SSD–equipped hosting solution will be a great choice.
