For many years there seemed to be only one trustworthy solution to store info on your computer – employing a hard drive (HDD). Nonetheless, this type of technology is by now expressing it’s age – hard disks are actually noisy and sluggish; they are power–hungry and have a tendency to produce lots of warmth throughout intensive operations.
SSD drives, on the contrary, are quick, use up significantly less power and are also far less hot. They offer an exciting new method of file access and storage and are years in advance of HDDs in terms of file read/write speed, I/O efficiency and then energy efficacy. See how HDDs stand up up against the more recent SSD drives.
1. Access Time
After the launch of SSD drives, data access speeds have gone through the roof. Because of the unique electronic interfaces found in SSD drives, the common data file access time has been reduced into a all–time low of 0.1millisecond.
HDD drives rely on rotating disks for files storage applications. When a file is being accessed, you have to wait around for the appropriate disk to get to the appropriate position for the laser to view the file you want. This ends in a standard access speed of 5 to 8 milliseconds.
2. Random I/O Performance
The random I/O performance is extremely important for the general performance of any data storage device. We have run detailed lab tests and have confirmed an SSD can deal with at the least 6000 IO’s per second.
Having an HDD drive, the I/O performance steadily improves the more you use the drive. Nonetheless, as soon as it extends to a specific limit, it can’t proceed faster. And due to the now–old technology, that I/O limit is much below what you might get with a SSD.
HDD are only able to go so far as 400 IO’s per second.
SSD drives are made to have as less moving elements as feasible. They use a comparable technique like the one employed in flash drives and are more trustworthy when compared to traditional HDD drives.
SSDs offer an typical failing rate of 0.5%.
As we have already noted, HDD drives rely on rotating hard disks. And anything that uses a great number of moving parts for lengthy periods of time is more prone to failing.
HDD drives’ typical rate of failing varies somewhere between 2% and 5%.
4. Energy Conservation
SSD drives are usually smaller compared to HDD drives and also they lack any kind of moving elements at all. This means that they don’t produce as much heat and need less energy to operate and much less energy for cooling down purposes.
SSDs take in between 2 and 5 watts.
HDD drives are renowned for becoming loud. They demand a lot more energy for cooling down reasons. Within a hosting server containing different HDDs running continuously, you will need a large amount of fans to ensure that they’re cooler – this may cause them far less energy–economical than SSD drives.
HDDs use up in between 6 and 15 watts.
5. CPU Power
The quicker the data accessibility speed is, the swifter the file calls will be adressed. Consequently the CPU won’t have to save allocations waiting for the SSD to answer back.
The common I/O wait for SSD drives is 1%.
When compared to SSDs, HDDs enable not so quick data accessibility rates. The CPU will be required to wait around for the HDD to return the demanded data, scheduling its allocations in the meanwhile.
The standard I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
The vast majority of Domaci Hosting’s completely new servers now use solely SSD drives. Our own tests have indicated that having an SSD, the common service time for any I/O request whilst performing a backup continues to be under 20 ms.
In comparison with SSD drives, HDDs provide considerably slower service times for input/output calls. In a hosting server backup, the standard service time for any I/O request varies between 400 and 500 ms.
7. Backup Rates
Talking about backups and SSDs – we have found a significant improvement in the back up rate since we switched to SSDs. Now, a standard server back–up requires merely 6 hours.
Through the years, we have got employed largely HDD drives with our web servers and we’re familiar with their functionality. With a server pre–loaded with HDD drives, a full web server back up may take about 20 to 24 hours.
With Domaci Hosting, you can get SSD–powered website hosting services at affordable prices. Our VPS services can include SSD drives automatically. Get an web hosting account here and witness the way your sites will become better automatically.
