For decades there was only one dependable path to keep information on a personal computer – by using a hard disk drive (HDD). Nonetheless, this sort of technology is by now displaying it’s age – hard drives are noisy and sluggish; they can be power–hungry and tend to generate quite a lot of warmth throughout intensive procedures.
SSD drives, however, are quick, use up significantly less power and tend to be much cooler. They provide a whole new solution to file access and storage and are years in advance of HDDs in terms of file read/write speed, I/O performance and energy capability. Discover how HDDs stand up up against the more recent SSD drives.
1. Access Time
With the launch of SSD drives, file access rates have gone through the roof. Thanks to the brand new electronic interfaces used in SSD drives, the typical file access time has shrunk into a all–time low of 0.1millisecond.
HDD drives even now utilize the same fundamental data file access technique that was actually created in the 1950s. Even though it has been much advanced since that time, it’s slower as compared with what SSDs are providing. HDD drives’ data access speed can vary between 5 and 8 milliseconds.
2. Random I/O Performance
The random I/O performance is important for the overall performance of a data file storage device. We have run extensive trials and have established an SSD can handle at the least 6000 IO’s per second.
Throughout the exact same tests, the HDD drives turned out to be much slower, with only 400 IO operations addressed per second. Even though this feels like a significant number, when you have a busy server that hosts loads of well known web sites, a slow harddrive can cause slow–loading web sites.
SSD drives lack virtually any moving parts, which means that there’s a lesser amount of machinery within them. And the fewer literally moving components you will find, the lower the prospect of failure are going to be.
The standard rate of failing of an SSD drive is 0.5%.
As we have previously noted, HDD drives use rotating disks. And anything that takes advantage of many moving elements for continuous amounts of time is at risk from failing.
HDD drives’ average rate of failure ranges somewhere between 2% and 5%.
4. Energy Conservation
SSDs are lacking moving parts and require almost no cooling down power. They also demand a small amount of electricity to operate – lab tests have revealed that they’ll be powered by a standard AA battery.
As a whole, SSDs take in amongst 2 and 5 watts.
HDD drives can be renowned for being noisy; they can be prone to getting hot and whenever there are several hard drives inside a web server, you need a further a / c device used only for them.
All together, HDDs take in between 6 and 15 watts.
5. CPU Power
Thanks to SSD drives’ better I/O efficiency, the main server CPU will be able to work with file demands a lot quicker and save time for other functions.
The regular I/O wait for SSD drives is only 1%.
HDD drives permit sluggish accessibility rates compared with SSDs do, resulting for the CPU required to wait around, although scheduling assets for the HDD to find and return the demanded file.
The average I/O delay for HDD drives is just about 7%.
6.Input/Output Request Times
In real life, SSDs carry out as wonderfully as they performed throughout the lab tests. We ran a full system backup on one of our own production machines. During the backup procedure, the common service time for I/O demands was indeed below 20 ms.
Sticking with the same server, however this time furnished with HDDs, the effects were totally different. The regular service time for an I/O query changed somewhere between 400 and 500 ms.
7. Backup Rates
One more real–life development will be the speed with which the data backup has been made. With SSDs, a hosting server data backup now can take less than 6 hours using our server–enhanced software.
On the flip side, with a web server with HDD drives, a comparable data backup normally takes three or four times as long to finish. A full back up of an HDD–powered web server often takes 20 to 24 hours.
Should you wish to quickly enhance the overall performance of your respective sites without the need to transform any code, an SSD–powered web hosting service will be a very good choice. Have a look at Webtor’s shared web hosting packages plus the VPS servers – these hosting solutions offer quick SSD drives and are offered at good prices.
