SSDs vs HDDs
Look into the Pro’s and Con’s of HDD and SSD drives
Presently, just about all brand new computer systems contain SSD drives as opposed to HDD drives. You can see superlatives on them all over the specialized press – that they’re a lot quicker and operate much better and they are the future of home computer and laptop production.
Having said that, how do SSDs stand up in the web hosting environment? Can they be well–performing enough to substitute the proven HDDs? At Site Quay, we’ll make it easier to much better understand the distinctions among an SSD and an HDD and decide the one that most accurately fits you needs.
1. Access Time
SSD drives have a brand–new & imaginative approach to data storage according to the use of electronic interfaces rather than just about any moving parts and spinning disks. This innovative technology is noticeably faster, permitting a 0.1 millisecond file accessibility time.
The technology powering HDD drives goes all the way back to 1954. And although it’s been substantially processed in recent times, it’s nonetheless can’t stand up to the ingenious ideas driving SSD drives. With today’s HDD drives, the very best file access speed you’ll be able to attain may differ in between 5 and 8 milliseconds.
2. Random I/O Performance
Due to the new radical file storage approach embraced by SSDs, they have quicker data access rates and swifter random I/O performance.
In the course of our lab tests, all SSDs showed their ability to manage a minimum of 6000 IO’s per second.
Hard drives offer reduced file access speeds because of the older file storage space and accessibility concept they’re implementing. Additionally they show significantly sluggish random I/O performance when compared with SSD drives.
Throughout Site Quay’s tests, HDD drives addressed an average of 400 IO operations per second.
3. Reliability
The absence of moving components and spinning disks within SSD drives, and also the recent advancements in electric interface technology have ended in a significantly risk–free data file storage device, with a normal failing rate of 0.5%.
Since we have already documented, HDD drives depend on spinning disks. And anything that uses plenty of moving elements for lengthy time periods is at risk from failing.
HDD drives’ normal rate of failing can vary somewhere between 2% and 5%.
4. Energy Conservation
SSD drives function virtually soundlessly; they don’t produce excessive warmth; they don’t mandate added air conditioning options and then consume far less energy.
Tests have demostrated the average electrical power use of an SSD drive is amongst 2 and 5 watts.
From the minute they were built, HDDs have always been very electric power–heavy products. And when you have a hosting server with a bunch of HDD drives, it will add to the month to month power bill.
On average, HDDs use up in between 6 and 15 watts.
5. CPU Power
SSD drives allow for quicker file access rates, that, in turn, permit the processor to accomplish file calls much quicker and then to go back to different tasks.
The typical I/O wait for SSD drives is 1%.
In comparison with SSDs, HDDs enable not so quick data access rates. The CPU is going to wait around for the HDD to send back the inquired data file, saving its allocations for the time being.
The average I/O wait for HDD drives is around 7%.
6.Input/Output Request Times
Almost all of Site Quay’s completely new machines now use exclusively SSD drives. Each of our lab tests have shown that by using an SSD, the normal service time for an I/O request while doing a backup remains below 20 ms.
With the same web server, however this time equipped with HDDs, the end results were completely different. The common service time for any I/O query fluctuated between 400 and 500 ms.
7. Backup Rates
Speaking about back–ups and SSDs – we’ve witnessed an effective improvement with the back up speed since we turned to SSDs. Right now, a standard web server back–up can take only 6 hours.
In contrast, with a server with HDD drives, the same back up may take three to four times as long in order to complete. An entire backup of an HDD–equipped web server normally takes 20 to 24 hours.
To be able to immediately improve the efficiency of one’s web sites without the need to transform any code, an SSD–powered website hosting solution is really a great alternative. Take a look at Site Quay’s Linux hosting packages packages and the Linux VPS web hosting – our solutions highlight fast SSD drives and are offered at competitive prices.
