For many years there was a single trustworthy way to keep info on a computer – using a hard drive (HDD). However, this sort of technology is currently demonstrating its age – hard disk drives are really loud and sluggish; they’re power–hungry and tend to create a great deal of warmth for the duration of intense procedures.
SSD drives, however, are quick, use up significantly less energy and are generally much cooler. They furnish a new method to file accessibility and data storage and are years in advance of HDDs regarding file read/write speed, I/O performance and power capability. Figure out how HDDs stand up up against the more recent SSD drives.
1. Access Time
Resulting from a revolutionary new method of disk drive general performance, SSD drives allow for much quicker data accessibility rates. Having an SSD, file accessibility instances tend to be lower (as small as 0.1 millisecond).
The technology powering HDD drives goes all the way back to 1954. Even though it’s been noticeably enhanced over the years, it’s still no match for the ground breaking technology powering SSD drives. With today’s HDD drives, the best data file access rate you are able to attain differs somewhere between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is really important for the efficiency of a data file storage device. We have run thorough trials and have established that an SSD can deal with no less than 6000 IO’s per second.
With a HDD drive, the I/O performance steadily enhances the more you use the hard drive. Having said that, once it actually reaches a specific limit, it can’t go faster. And due to the now–old technology, that I/O limit is noticeably lower than what you could get having an SSD.
HDD are only able to go as much as 400 IO’s per second.
SSD drives do not have any kind of rotating elements, meaning there is far less machinery within them. And the less actually moving components you will discover, the lower the possibilities of failure are going to be.
The regular rate of failing of an SSD drive is 0.5%.
Since we already have noted, HDD drives make use of rotating disks. And anything that makes use of lots of moving parts for extented periods of time is at risk of failure.
HDD drives’ average rate of failing can vary between 2% and 5%.
4. Energy Conservation
SSDs don’t have any moving elements and require very little cooling down power. In addition they require very little electricity to perform – trials have indicated that they’ll be powered by a normal AA battery.
As a whole, SSDs take in between 2 and 5 watts.
From the second they were made, HDDs have always been extremely energy–hungry products. When you have a server with a couple of HDD drives, this will likely add to the monthly power bill.
Typically, HDDs use up between 6 and 15 watts.
5. CPU Power
SSD drives permit a lot quicker file access rates, which, in return, allow the processor to perform file requests considerably faster and afterwards to return to different jobs.
The typical I/O wait for SSD drives is just 1%.
When you use an HDD, you have to devote time anticipating the results of your file ask. This means that the CPU will be idle for further time, awaiting the HDD to respond.
The typical I/O delay for HDD drives is about 7%.
6.Input/Output Request Times
Almost all of Sibanda Hosting’s completely new web servers now use only SSD drives. All of our tests have demostrated that by using an SSD, the common service time for any I/O request although performing a backup stays under 20 ms.
With the exact same hosting server, however, this time equipped with HDDs, the end results were completely different. The normal service time for an I/O query fluctuated between 400 and 500 ms.
7. Backup Rates
An additional real–life improvement will be the rate at which the backup has been produced. With SSDs, a hosting server back up currently will take less than 6 hours by using Sibanda Hosting’s hosting server–designed software.
Over time, we’ve used mainly HDD drives on our servers and we’re familiar with their overall performance. On a web server built with HDD drives, a full web server backup typically takes around 20 to 24 hours.
