For years there seemed to be only one trustworthy solution to store data on a computer – utilizing a disk drive (HDD). Having said that, this kind of technology is currently expressing its age – hard drives are noisy and sluggish; they can be power–hungry and tend to produce a lot of warmth during intensive operations.
SSD drives, on the contrary, are fast, take in way less power and are much cooler. They provide an innovative approach to file access and storage and are years in advance of HDDs in relation to file read/write speed, I/O effectiveness and power capability. Figure out how HDDs fare up against the newer SSD drives.
1. Access Time
SSD drives offer a brand–new & imaginative way of data storage based on the usage of electronic interfaces as an alternative to any kind of moving parts and rotating disks. This unique technology is quicker, enabling a 0.1 millisecond data file access time.
HDD drives rely on rotating disks for data storage uses. When a file will be utilized, you need to await the appropriate disk to get to the appropriate position for the laser beam to view the data file in question. This leads to a standard access speed of 5 to 8 milliseconds.
2. Random I/O Performance
The random I/O performance is extremely important for the performance of any file storage device. We have carried out substantial lab tests 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 improves the more you employ the drive. Even so, once it actually reaches a specific restriction, it can’t go faster. And because of the now–old concept, that I/O cap is significantly below what you might have having an SSD.
HDD can only go as far as 400 IO’s per second.
SSD drives do not have virtually any moving elements, which means that there’s a lesser amount of machinery in them. And the less literally moving parts you’ll find, the fewer the probability of failure will be.
The average rate of failure of an SSD drive is 0.5%.
As we have already documented, HDD drives make use of rotating disks. And something that utilizes plenty of moving parts for prolonged time periods is prone to failing.
HDD drives’ average rate of failing can vary among 2% and 5%.
4. Energy Conservation
SSD drives are much smaller compared to HDD drives and they don’t possess any moving components whatsoever. It means that they don’t generate so much heat and require much less electricity to work and less energy for chilling purposes.
SSDs use up somewhere between 2 and 5 watts.
HDD drives are renowned for staying noisy. They need more power for cooling down purposes. With a web server containing several HDDs running all the time, you will need a great number of fans to make sure they’re cool – this will make them a lot less energy–effective than SSD drives.
HDDs consume in between 6 and 15 watts.
5. CPU Power
The swifter the file accessibility speed is, the faster the data file calls can be treated. Consequently the CPU will not have to arrange allocations waiting for the SSD to answer back.
The regular I/O wait for SSD drives is merely 1%.
If you use an HDD, you need to invest more time watching for the results of one’s file call. This means that the CPU will stay idle for more time, looking forward to the HDD to react.
The regular I/O wait for HDD drives is around 7%.
6.Input/Output Request Times
The bulk of CHENNAI DOMAIN’s new machines are now using simply SSD drives. All of our tests have demonstrated that having an SSD, the common service time for any I/O request while running a backup continues to be below 20 ms.
Using the same hosting server, however this time equipped with HDDs, the results were very different. The regular service time for an I/O request changed somewhere between 400 and 500 ms.
7. Backup Rates
Speaking about back–ups and SSDs – we’ve detected an effective improvement in the back–up rate since we moved to SSDs. Right now, a common hosting server back–up takes just 6 hours.
We employed HDDs mainly for several years and we have pretty good expertise in exactly how an HDD functions. Generating a backup for a hosting server furnished with HDD drives will take about 20 to 24 hours.
To be able to instantaneously raise the overall performance of your websites and never have to modify any code, an SSD–equipped web hosting solution will be a really good option.
