For many years there was just one efficient solution to keep info on a computer – with a hard disk drive (HDD). Then again, this sort of technology is presently displaying it’s age – hard disks are really noisy and sluggish; they are power–ravenous and are likely to create a great deal of heat for the duration of intensive procedures.
SSD drives, on the contrary, are fast, use up way less power and tend to be far less hot. They feature a new method of file access and data storage and are years in front of HDDs regarding file read/write speed, I/O efficiency and energy effectivity. Figure out how HDDs fare against the more recent SSD drives.
1. Access Time
Resulting from a revolutionary new method to disk drive functionality, SSD drives enable for noticeably faster data access speeds. Having an SSD, file access times tend to be lower (only 0.1 millisecond).
HDD drives count on spinning disks for data storage reasons. Each time a file is being accessed, you will have to await the appropriate disk to reach the appropriate place for the laser to reach the file you want. This ends in a typical access speed of 5 to 8 milliseconds.
2. Random I/O Performance
The random I/O performance is crucial for the functionality of a file storage device. We’ve carried out extensive testing and have determined that an SSD can handle no less than 6000 IO’s per second.
With an HDD drive, the I/O performance gradually raises the more you apply the disk drive. Having said that, once it extends to a particular limitation, it can’t get swifter. And because of the now–old technology, that I/O restriction is much less than what you can receive with a SSD.
HDD are only able to go as far as 400 IO’s per second.
SSD drives are meant to include as less moving parts as is practical. They utilize an identical technique like the one employed in flash drives and are also much more reliable than conventional HDD drives.
SSDs have an typical failure rate of 0.5%.
With an HDD drive to function, it needs to rotate a few metallic disks at more than 7200 rpm, holding them magnetically stable in the air. There is a good deal of moving elements, motors, magnets as well as other gadgets crammed in a tiny location. Hence it’s obvious why the standard rate of failing of any HDD drive can vary among 2% and 5%.
4. Energy Conservation
SSD drives are much smaller compared to HDD drives and also they lack any kind of moving parts whatsoever. This means that they don’t generate as much heat and require much less electricity to work and less energy for cooling reasons.
SSDs use up amongst 2 and 5 watts.
From the second they were developed, HDDs have invariably been very energy–ravenous equipment. And when you have a server with several HDD drives, this will certainly raise the regular power bill.
Normally, HDDs use up somewhere between 6 and 15 watts.
5. CPU Power
SSD drives provide for swifter data access speeds, that, in turn, enable the processor to accomplish file queries much quicker and to return to additional duties.
The typical I/O wait for SSD drives is actually 1%.
If you use an HDD, you’ll have to spend time waiting around for the outcome of your file ask. Consequently the CPU will remain idle for extra time, waiting for the HDD to reply.
The average I/O wait for HDD drives is about 7%.
6.Input/Output Request Times
In real life, SSDs conduct as wonderfully as they did in the course of our lab tests. We ran a complete system data backup on one of our production web servers. Through the backup process, the typical service time for any I/O calls was basically under 20 ms.
In contrast to SSD drives, HDDs feature considerably reduced service times for input/output queries. During a hosting server backup, the common service time for any I/O request varies between 400 and 500 ms.
7. Backup Rates
You can easily experience the real–world benefits to utilizing SSD drives every day. For example, with a hosting server with SSD drives, a full back up will take only 6 hours.
Throughout the years, we’ve used largely HDD drives with our servers and we are knowledgeable of their performance. On a hosting server pre–loaded with HDD drives, an entire server data backup may take about 20 to 24 hours.
If you want to without delay add to the overall performance of your websites without the need to alter just about any code, an SSD–powered hosting service will be a excellent choice. Have a look at the Linux shared website hosting packages and the Linux VPS web hosting – our services include really fast SSD drives and are offered at competitive prices.
