For years there was just one single dependable method to store information on a personal computer – utilizing a hard disk drive (HDD). On the other hand, this type of technology is already displaying it’s age – hard disk drives are loud and sluggish; they are power–hungry and are likely to generate a lot of heat in the course of serious procedures.
SSD drives, on the contrary, are quick, consume a smaller amount energy and are much cooler. They offer an innovative method to file accessibility and storage and are years ahead of HDDs relating to file read/write speed, I/O efficiency as well as energy effectivity. Discover how HDDs stand up up against the newer SSD drives.
1. Access Time
SSD drives provide a completely new & ingenious method to data storage in accordance with the usage of electronic interfaces in lieu of any moving components and spinning disks. This innovative technology is faster, permitting a 0.1 millisecond data accessibility time.
HDD drives continue to work with the same basic data access concept that’s actually created in the 1950s. Though it was vastly improved since that time, it’s sluggish as compared with what SSDs will provide. HDD drives’ data access speed can vary in between 5 and 8 milliseconds.
2. Random I/O Performance
As a result of the new significant data file storage strategy shared by SSDs, they offer a lot quicker file access speeds and quicker random I/O performance.
Throughout alvahosting’s lab tests, all SSDs confirmed their capacity to manage at least 6000 IO’s per second.
Over the same tests, the HDD drives demonstrated that they are much slower, with 400 IO operations maintained per second. While this feels like a great number, for people with a busy web server that hosts lots of famous websites, a sluggish disk drive may result in slow–loading sites.
SSD drives are designed to have as fewer rotating parts as is feasible. They utilize a similar concept to the one utilized in flash drives and are generally much more trustworthy when compared to traditional HDD drives.
SSDs have an typical failure rate of 0.5%.
As we have previously documented, HDD drives make use of spinning hard disks. And something that uses plenty of moving elements for extented time frames is at risk of failure.
HDD drives’ average rate of failing ranges somewhere between 2% and 5%.
4. Energy Conservation
SSD drives function virtually soundlessly; they don’t generate surplus heat; they don’t call for added cooling alternatives and consume much less power.
Trials have demostrated that the typical power intake of an SSD drive is between 2 and 5 watts.
HDD drives are renowned for getting noisy. They need further energy for cooling purposes. On a server which has a variety of HDDs running all of the time, you’ll need a lot of fans to keep them cool – this will make them much less energy–economical than SSD drives.
HDDs consume between 6 and 15 watts.
5. CPU Power
The swifter the data file access speed is, the faster the data file requests can be treated. As a result the CPU won’t have to arrange assets expecting the SSD to respond back.
The regular I/O delay for SSD drives is barely 1%.
HDD drives permit slower accessibility rates compared with SSDs do, which will result for the CPU needing to hang on, although arranging resources for the HDD to find and return the required file.
The typical I/O delay for HDD drives is approximately 7%.
6.Input/Output Request Times
Almost all of alvahosting’s brand new machines moved to simply SSD drives. Each of our lab tests have demostrated that with an SSD, the common service time for an I/O request whilst performing a backup continues to be below 20 ms.
Sticking with the same web server, however this time equipped with HDDs, the results were totally different. The average service time for an I/O call fluctuated between 400 and 500 ms.
7. Backup Rates
Speaking about backups and SSDs – we’ve detected a substantual development with the data backup rate as we moved to SSDs. Today, a regular hosting server back up can take only 6 hours.
On the flip side, with a hosting server with HDD drives, the same back up may take three or four times as long to complete. A full back–up of any HDD–equipped web server usually takes 20 to 24 hours.
